Usage Syntax:

tst10.exe /r:script.txt [options]

/r:script.txt      run script.txt
[options]          any of these:

/o:output.txt      send session output to output.txt
/m                 run script in minimized window

Usage Example:

tst10.exe /r:script.txt /o:output.txt /m

Scripting Syntax:

HOSTNAME PORT      port number optional, default: 23
WAIT "string"      string to wait for
SEND "string"      string to send
\"                 represents the a quote character
\m                 represents a <CR/LF>
\\                 represents the backslash character

Scripting Example:

hostname.com 23
WAIT "login"
SEND "root\m"
WAIT "password"
SEND "mypassword\m"
WAIT ">"
SEND "dip internet.dip\m"
WAIT ">"

Scripting Note:

You can start with either WAIT or SEND commands,
but you *must* alternate them. ie: you can't use two
or more WAIT or SEND in a row.

Note:

TST will disconnect and close as soon
as its done with the last entry of the script.

If you need to, you can type in the terminal
window while the script is running.

You can use the tool to automate not just sessions where you log into another system via the telnet protocol, but other types of connections where you might use the telnet command.

E.g., I often telnet to the Simple Mail Transfer Protocol (SMTP) port, which is port 25 on mail servers, to troubleshoot connections. The Telnet Scripting Tool (TST) can be used to automate this type of testing as well.

For instance, I created a file, testSMTP.txt, to use with the Telnet Scripting Tool in timing how long it was taking a mail server to display its banner. The banner from mail server software, such as sendmail, usually begins with the code 220, e.g. 220 mail.example.com ESMTP Sendmail 8.13.8/8.13.8; Mon, 29 Dec 2008 21:39:48 -0500. So, I placed the following commands in a file to connect to a mail sever at address 192.168.0.5

192.168.0.5 25
WAIT "220"
SEND "quit\m"

The first line specifies the IP address of the server followed by the port number to use, in this case port 25 for an SMTP connection. The WAIT "220" tells the Telnet Scripting Tool to wait for the string 220 from the server and then to send the quit command followed by a carriage return and line feed, e.g. the characters that would be sent if I typed "quit" and hit the Enter key

I then opened a command prompt on a Windows XP system and entered the command below:

C:\DOCUME~1\JSmith\MYDOCU~1\>"\program files\network\tst10\tst10.exe" /r:testSMTP.txt

In this case the file testSMTP.txt was in the current directory, but the tst10.exe program was in \program files\network\tst10\tst10.exe

Note: before using the program,I uploaded the executable, TST10.exe, to VirusTotal, a service that scans files with many different antivirus programs. It checked the file with 38 antivirus programs. None of them found any malware within the file (see MD5: 4aee641e6ddb9a5fa95f590273729708). Note: the viradd and virsize in the Portable Executable (PE) information stand for "Virtual Address" and "Virtual Size" respectively (see Strange tcpip header?).

The explanation was that it derives from the Roman use of the letter C to stand for the K sound. The Anglo-Saxons in what is now Great Britain adopted the Roman system. After the Battle of Hastings in which William the Conqueror defeated the Anglo-Saxon forces led by Harold Godwinson many French words became part of the English language. The Norman French pronounced "C" as "S" before the letters "I,E,(Y)". So "C" became a letter with two sounds.

You can set the value of a variable with myvar="some text". You can view the value of the variable using $myvar or ${myvar}. Putting the "$" in front of the variable name causes BASH to use the value stored in myvar.

$ myvar="some text"
$ echo $myvar
some text
$ echo ${myvar}
some text

There is sometimes an advantage to the format that encloses the variable name in curly braces, i.e. the ${myvar} format.

$ echo "foo$myvar"
foosome text
$ echo "foo$myvarother text"
foo text
$ echo "foo${myvar}other text"
foosome textother text

In the above example, in the instance where the curly braces weren't used, the value of myvar wasn't displayed, because BASH didn't know I wanted myvar rather than myvarother, which has no value assigned to it, so it just dispalyed "foo text". In the second instance where the curly braces were used, BASH could tell I wanted the vaue of myvar and displayed "foo some textother text".

Substrings can be extracted from a string by chopping characters from the beginning and end of a string.

Chopping a trailing character:

You can chop a trailing character from a string in BASH by placing the variable name inside ${ }, such as ${myvar}, and then using %<char>. E.g. suppose myvar has the value "0064092004008999,". To remove the trailing comma from the end of the variable, you could use myvar=${myvar%,}

$ myvar="0064092004008999,"
$ echo ${myvar%,}
0064092004008999

If you wanted to remove the last "9" and all characters that appear after it in the line, you can use "*" in the expression.

$ myvar="0064092004008999,"
$ echo ${myvar%9*}
006409200400899

In the example above, the shortest matching substring is selected and removed, i.e. the "9,". If you wanted to remove the longest matching substring, e.g. every character from the first "9" onwards, you could use

$ myvar="0064092004008999,"
$ echo ${myvar%%9*}
00640

Chopping leading characters:

You can chop leading characters from a string by using # or ##. E.g. suppose myvar has the value "SNMPv2-MIB::sysContact.0 = STRING: John Smith". If you only want the name John Smith, you can use ## to remove the longest substring containing the ":" character. I.e., using myvar=${myvar##*:} wold work. If you instead used only one "#", the shortest matching substring would be removed. I.e., using myvar=${myvar#*:} would return :sysContact.0 = STRING: John Smith, where all characters up to and including the first ":" are removed.

$ myvar="SNMPv2-MIB::sysContact.0 = STRING: John Smith"
$ echo ${myvar##*:}
John Smith
$ echo ${myvar#*:}
:sysContact.0 = STRING: John Smith

But rather than page through it by the above method, you can also transfer the contents of the log to a TFTP server. Instructions for setting up a TFTP server on a Linux system can be found at Setting Up a Linux TFTP Server.

To redirect the output to a TFTP server, use the command get log traffic > tftp <IP Address> <filename>, substituting the IP address of the TFTP server for <IP Address> and the name of the file you want to write to on the TFTP server for <filename>. E.g. the command below would store the log file on a TFTP server at IP address 192.168.0.5 in the file NetScreen-log.txt. Note: the file NetScreen-log.txt must already exist on the server, though it may be an empty file prior to transfer of the log file from the NetScreen firewall

ns5gt-> get log traffic > tftp 192.168.0.5 NetScreen-log.txt

If you see a tftp timeout max error message followed by a tftp abort message, firewall software on the TFTP server may be blocking the file transfer. If you see a !rcv tftp error(1) File not found message then you likely have mistyped the name of the file that should be pre-existing on the server or the permissions on that file are not set appropriately, e.g., if the TFTP server is a Linux or Unix system, the file should have world read+write permissions set on it, which you can set with chmod 666 filename.

The Trivial File Transport Protocol (TFTP) proivides a mechanism to read files from or write files to a remote server. It is similar to the File Transfer Protocol (FTP), but doesn't have all of the features of FTP, such as an authentication mechanism.

The instructions below were written for the CentOS distribution of Linux, but TFTP server software is available for Linux, Unix, Windows and other operating systems. For Linux systems that use the Red Hat Package Manager (RPM) package management system, you can determine if the tftp-server package is installed with the command rpm -qi tftp-server.

# rpm -qi tftp-server
package tftp-server is not installed

The tftp-server package depends on the xinetd package; you can check if that package is installed with rpm -qi xinetd. If it isn't installed and you use the Yellow dog Updater, Modified (YUM) package management utility, you can install both packages with yum install tftp-server xinetd. To install just the tftp-server package, use yum install tftp-server. The installation of the tftp-server package will create the directory /tftpboot on the system. The directory should be set to 755 for tftp clients to be able to read from or write to files in the directory.

# ls -ld /tftpboot
drwxr-xr-x 2 root root 4096 Dec 24 14:15 /tftpboot

You next need to turn on the tftp service with the chkconfig command.

# chkconfig tftp on

You can verify that the service is available with chkconfig --list tftp.

# chkconfig --list tftp
tftp            on

TFTP uses the User Datagram Protocol and listens for data on port 69, so you can also use netstat -a | grep tftp to check on whether the system is listening for data on port 69. You should see something like the following if it is listening:

udp        0      0 *:tftp                      *:*

If you have firewall software running on the TFTP server, you will also need to allow connectivity to UDP port 69 through the firewall. You can do this on a CentOS system through the GUI by taking the following steps:

1. Click on System.
2. Click on Administration.
3. Select Security Level and Firewall
4. Under Firewall Options, select other ports.
5. Click on the Add button.
6. Put 69 in the port field and select udp for the protocol.
7. Click on OK.
8. Click on OK again.
9. When prompted to override any existing firewall configuration, click on Yes.

To be able to write to a file on the tftp server, e.g. a file named firewall-log.txt in the /tftpboot directory, you need to first create the file with the touch command and then set the permissions on the file so it is "world" writable.

# touch /tftpboot/firewall-log.txt
# chmod 666 /tftpboot/firewall-log.txt

Once you have the TFTP server configured, you can then transfer files from the tftp client to the server.

Yes. Light-emitting diodes (LEDs) are small light sources illuminated by the movement of electrons through a semiconductor material - and they are worth the extra money.

According to ENERGY STAR®, LEDs are very energy efficient when producing individual colors, such as those used in many holiday lights. LEDs use up to 90 percent less energy than incandescent bulbs to produce the same amount of light.

The amount of electricity consumed by just one 7-watt incandescent bulb could power 140 LEDs - enough to light two 24-foot strings of lights.

Still not convinced? ENERGY STAR qualified LEDs are worth the extra money because they:

• last up to 10 times longer than traditional incandescent strands,
• are cool to the touch, reducing the risk of fire,
• don't have filaments or glass so they are much more durable and shock-resistant than other light strings,
• come with a three-year warranty, and
• will absorb their initial cost after about one to two years of use.

At hpboid.exe Windows process - What is it?, I found the hpboid process described as follows:

The process HP Status Server Module belongs to the software HP Status Server or HP Deskjet or HP Status Server Module by Hewlett-Packard Company (www.hp.com).

Description: File hpboid.exe is located in a subfolder of C:\Windows\System32 or sometimes in the folder C:\Windows\System32. Known file sizes on Windows XP are 73728 bytes (96% of all occurrence), 61440 bytes.
The program has no visible window. File hpboid.exe is not a Windows system file.

At have multiple hpboid.exe & hpbpro.exe processes, WHY?, I found others reporting the same problem. Someone posted the following script as a solution for eliminating the processes.

net stop spooler
sleep 5
taskkill /F /IM HPBOID.exe
taskkill /F /IM HPBPRO.exe
sleep 5
net start spooler

The poster suggested the script be saved as kill_hpprocess.cmd and run through the Windows task scheduler. The poster stated he found the script at HPBOID.EXE remove it permanently. The author of the blog article there states the following:

Some HP Printer drivers install a service called HP Status Server based on an executable called hpboid.exe, on terminal service machine it start itself many times and it doesn't remove it whenever user disconnect itself consuming too much resources.

He offers some steps to solve the problem on that webpage. Someone else posted the script there as a way to solve the problem. Another poster suggests the problem can be solved instead following advice from Hewlett-Packard (HP), which is the company responsible for hpboid.exe and hpbpro.exe. He references HP Deskjet 6980 Series Printer - Computer Crashes when Printing Over a Network and Network Task Manager Shows Multiple Instances of hpboid.exe Running

The HP webpage lists the following as solutions to the problem:

Issue

Task Manager shows multiple instances of hpboid.exe running. This consumes all the resources and the computer ultimately crashes. This happens when the printer is printing over a network.

Solution

Choose one of the solutions below.

Solution one

Follow the steps below to resolve this issue.

1. Click Start , and then click Run.
2. In the Run dialog box, type services.msc and click OK.
3. Search for HP status server and right-click it. Click Properties, and then click Stop
4. Click Apply and then click OK.
5. Check whether the issue persists. If the issue persists, repeat the same steps for HP port resolver and stop this service.

Solution two

Search for hpboid.exe and delete the file. Deleting the file will not affect the printing functionality.

I followed the steps HP listed in solution one. I stoped the HP Status Server service. That reduced the number of hpboid.exe processes by only one, however, from 63 to 62. It did not reduce the number of hpbpro.exe processes. I stopped the HP Port Resolver service. That reduced the number of hpbpro.exe processes by one from 49 to 48. Since there were still many instances of each process running, I killed all of the others with the following commands:

taskkill /f /fi "imagename eq hpboid.exe"
taskkill /f /fi "imagename eq hpbpro.exe"


I saw a substantial reduction in the amount of memory being used when I killed all instances of those two processes.

I used the runas command to run the following command under an administrator account on the system. In this case the "owner" account was in the administrators group on the system.

C:\>runas /user:owner "RunDLL32 shell32.dll,Control_RunDLL %SystemRoot%\system32\TIMEDATE.cpl"

That command opened the Date and Time Properties window. When I clicked on the Time Zone tab, I found the time zone set to "GMT-8:00 Pacific Time (US & Canada)", whereas it should have been set to "GMT-5:00 Eastern Time (US & Canda)". I could now change the timze zone.

The time zone can also be specified on the command line rather than changing it through the Date and Time Properties window. E.g. the command C:\>runas /user:owner "RunDLL32 shell32.dll,Control_RunDLL %SystemRoot%\system32\TIMEDATE.cpl,,/Z US Eastern Standard Time" would allow one to change the time zone to "(GMT-5:00) Indiana (East)". Of course, you don't need the runas /user:owner, if you are already logged into the system as an administrator.

NOTE: You do not encapsulate the time zone string in quotation (") marks. I have quotation marks around the entire rundll32 command for entering a command with spaces in it to the runas command.

You can see what the values are that you should use on the command line for your specific time zone by running regedit and navigating to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\Time Zones\.

In this case, I needed to use RunDLL32 shell32.dll,Control_RunDLL %SystemRoot%\system32\TIMEDATE.cpl,,/Z Eastern Standard Time rather than using "US Eastern Standard Time" to have the time zone be "(GMT-5:00) Eastern Time US & Canada". The value that appears under the Time Zone tab in the Date and Time Properties window is what is listed for the display value under each time zone within the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\Time Zones\ registry key.

When I changed the time zone, the time changed also to match the time zone change. I needed to reset it, which I did by opening a command window from the "owner" administrator account using runas /user:owner cmd. I then used the time command to reset the time.

In email from the Cron Daemon to the root account, I found messages with the following within them:

/etc/cron.daily/logrotate:

error: syslog:1 duplicate log entry for /var/log/maillog

I checked /etc/logrotate.conf, but didn't find any references to rotation of the maillog file there.

Contents of /etc/logrotate.conf:

# see "man logrotate" for details
# rotate log files weekly
weekly

# keep 4 weeks worth of backlogs
rotate 4

# create new (empty) log files after rotating old ones
create

# uncomment this if you want your log files compressed
#compress

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d

# no packages own wtmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    minsize 1M
    create 0664 root utmp
    rotate 1
}

# system-specific logs may be also be configured here.

I then checked the /etc/logrotate.d directory. I found maillogrotate there.

Contents of /etc/logrotate.d/maillogrotate:

# Begin maillogrotate control file
/var/log/maillog {
   daily
   rotate 14
   sharedscripts
   create 0600 root root
   missingok
   postrotate
   /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
   endscript
}
# End maillogrotate control file

I also checked the /etc/logrotate.d/syslog file, since syslog may rotate the file.

Contents of /etc/logrotate.d/syslog:

/var/log/messages /var/log/secure /var/log/maillog /var/log/spooler /var/log/boot.log /var/log/cron {
    sharedscripts
    postrotate
        /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null || true
        /bin/kill -HUP `cat /var/run/rsyslogd.pid 2> /dev/null` 2> /dev/null || true
    endscript
}

So it appears that both the /etc/logrotate.d/maillogrotate and the /etc/logrotate.d/syslog files were attempting to rotate the maillog file on a daily basis.

Checking notes posted on my blog, I found I resolved the problem on another email server, a Redhat Linux server, on Friday, September 17 of 2004, almost exactly 4 years ago, and had posted my notes in Daily Rotation of Mail Logs. In that case, I had removed the /var/log/maillog reference from /etc/logrotate.d/syslog, so I did the same thing in this case as well. But this time, I decided to leave the maillogrotate file in /etc/logrotate.d.

Checking my notes for the CentOS email server, I see that I had in the past removed the /var/log/maillog reference from /etc/logrotate.d/syslog. Some installation or upgrade must of led to the version of the file I created then being overwritten.

As I posted there, I would like to point out that he never claimed to have invented the Internet (see the Snopes article "Internet of Lies"). For a much fuller discussion of the topic and some history on the Internet’s development and Gore’s role in supporting advanced networking initiatives, I would recommend “ Al Gore and the Creation of the Internet”

His early vision of its potential and his support for funding of advanced networking activities was important. Vint Cerf, who has, I think appropriately, been dubbed the “father of the Internet” for his technical contributions, along with Bob Kahn, in designing the Internet Protocol, has credited Gore’s early support for advanced networking efforts (see "Vint Cerf responded to MSNBC").

I see the same tactic of taking an opponent’s statements out of context being widely used in the current campaign by both parties. Unfortunately, I suspect many Americans will make up their minds based on what they see in political ads that are designed to mislead them. The tactic used so successfully against Gore still works.

At the end of the installation, the installation software displays the message below:

After the installation, I clicked on Start, selected All Programs, then COPSSH, then Activate a User.

I selected a user and then proceeded to the next step where I typed in a passphrase, which is used to protect the private key for the account.

I then clicked on the Activate button, which produced the message below.

I selected the "This program installed correctly" option.

Since the system was using the firewall capability built into Windows Vista, I then clicked on the Start button, selected Control Panel, then Security then Windows Firewall, and then Change Settings.

I clicked on the Exceptions tab and then selected Add Port. At the Add Port window, I specified copSSH as the name for the firewall port and the default SSH port, which is port 22. SSH uses the TCP protocol.

I clicked on Ok and then OK again to create the firewall rule for copSSH. I was then able to use PuTTY to log into the system from another system.

If you would like to use another port other than the default port of 22, you need to edit the sshd_config file, which you will find within the etc directory beneath the directory in which you installed copSSH, e.g. \Program Files\copSSH\etc\sshd_config.

I suggest editing the file with WordPad rather than Notepad, because WordPad can handle the end of line characters used in the file so that each line appears one beneath the other rather than all lines appearing as one long line as they will in Notepad. WordPad can deal with the end of line character used on Unix and Linux systems better than Notepad. The file uses the linefeed character common for files on Unix and Linux systems rather than the combination of carriage return and linefeed characters that Microsoft Windows uses.

To change the port, locate the line below. Remove the "#" from the beginning of the line, which turns the line into a comment line. Then replace 22 with whatever number you wish to use for the port.

#Port 22

When you've changed the port, you will need to restart the SSH server service, which you can do by rebooting or simply stopping and restarting the service. To stop and restart the service from the command line, obtain a command prompt. If you aren't logged into an administrator account, you can use the command runas /user:administrator cmd from a command prompt to open another command prompt window under the administrator account.

C:\>net stop "Openssh SSHD"
The Openssh SSHD service is stopping.
The Openssh SSHD service was stopped successfully.


C:\>net start "Openssh SSHD"
The Openssh SSHD service is starting.
The Openssh SSHD service was started successfully.

You can verify copSSH is listening on the new port using the netstat command. E.g., if you set the port to 5622, you could use the command below:

C:\>netstat -an | find "5622"
  TCP    0.0.0.0:5622          0.0.0.0:0              LISTENING

When a scan is started, the following is displayed:

Scanning


Scanning all filesystems mounted under /mnt/scan/ directory.
The results of the scan will be saved in /tmp/scan_results.txt

Alt-F1 This screen.
Alt-F5 To see details of files being scanned.
Alt-F6 To see any malware found.
Ctrl-C TO cancel scanning.

You can also use Alt-F2, Alt-F3, or Alt-F4 to get a shell prompt. I used Alt-F2 to obtain a shell prompt.

When a system is booted from the rescue CD, the hard drive on the system is mounted under /mnt/scan. In this case, the hard drive is an IDE drive designated as hda2 by Linux, which is the operating system used on the F-Secure Rescue CD. So I could store the log files, which are as follows, somewhere under /mnt/scan/hda2.

scan_error.txt
scan_log.txt
scan_results.txt

On this system there was a C:\TEMP directory, so I decided to store them there. You can see the directories on the hard drive using the ls command, e.g. ls /mnt/scan/hda2/.

Using the pico editor on the CD, I created a script, which I named rebootwin in the /tmp directory to automatically reboot the system after 9 hours, presuming that the scan of the system should certainly be completed within that time (it took about 3 hours).

root@tty2[/]# cd /tmp
root@tty2[tmp]# pico rebootwin

I put the following commands in the script:

#!/bin/bash
date
sleep 9h
cp scan*.txt /mnt/scan/hda2/TEMP/.
reboot

The script prints the date and time and then "sleeps" for 9h. When that amount of time has elapsed, it copies the log files from the scanning process from the /tmp directory to the C:\TEMP directory on the system's hard drive. The system is then rebooted. If the system is set to boot from the hard drive first, rather than a CD-ROM drive, it will boot into Windows from the hard drive. If the system's BIOS is set to attempt to boot the system first from a CD in a CD-ROM drive, it will reboot from the F-Secure Rescue CD, but, unless a key is hit within a few seconds, it will not continue with a reboot into the antivirus scanning software, but will instead boot from the system's hard drive.

I saved the script with Ctrl-X and then made the script executable with the chmod command. I then started the script with ./rebootwin.

root@tty2[tmp]# chmod 755 test
root@tty2[tmp]# ./rebootwin
Sat Sep 13 23:52:46 UTC 2008

The next morning, I was able to check the results of the scanning process by examing the log files on the system's hard drive.

To search from the line I was on to the end of the document I can use .,$. With the substitute s command, you can search and replace text with commands of the form s/old text/new text. You can use the i option, if you don't want the case of letters to be considered, i.e. if you wish "A" and "a" to be treated the same, then you can use s/old text/new text/i. You can use the g option, if you wish to replace all occurrences of old text on the line, for cases where the text may occur multiple times on the same line, e.g. s/old text/new text/g. You can use whatever delimiter you wish to separate the parts of the command, e.g. you can use s:old text:new text:.

The \d in the command indicates that I am only looking for digits, i.e. 0 to 9. By enclosing the \d in parentheses, i.e. by using (\d), I can have the editor "remember" whatever it found between the parentheses. Then I can have it insert what it has remembered in the replacement text by using \1. If I had used multiple parentheses at various parts in the search text, then the second string I wanted remembered would be indicated with a \2. In this case the last digit of the year was all I wanted the editor to remember and insert appropriately in the substitutiong text.

If you wish to search an entire document, you can use 1,$ to represent the first line of the file through the last line, or you can just use % to represent the entire file.

To use BlackLight, simply download it and run the downloaded file. There is no installation process. When the scan is completed, BlackLight will report whether it found any hidden processes, files, or folders that may be part of a rootkit.

Analysis of the results of a RootkitRevealer scan requires more technical competence as some of the entries you see listed in its report may be normal for Windows systems and not necessarily a sign that the system has been "rootkitted".

The version information for the router I tested is shown below:

The Belkin F5D7230-4 router has a security logging feature that shows a "system log" and a "firewall log", but the logging capabilities provided by the router are extremely limited. There's no way to have a log transmitted by email or for log information to be transmitted from the router by syslog. And the information logged is very rudimentary.

The example below shows entries in the system log for attemnpts I made from a system at 192.168.2.4, which was on the WAN side of the router, to login with an incorrect password, from a system that wasn't allowed to remotely manage the router. The entries in the firewall log section are from an nmap scan I ran against the router from a system on the WAN side of the router.

The router provides the capability to set "client IP filters" that allow one to limit outbound access through the router from systems on the LAN side of the router. You can specify an IP range and port range to be blocked and whether the block should apply only during specified days of the week and times or whether the block should always apply. And you can easily enable and disable a block. Using that capability you can limit outbound email access to only certain systems, etc.

There is also a "Parental Control" feature. Belkin states "Belkin's Parental Control protects you and your children/employees from objectionable content on the web. Parental Control comes pre-configured to block many types of web content, but is custom configurable to be more or less restrictive. Any web site can easily be set to be either, always blocked, or always allowed." That feature requires a subscription to Belkin's parental control service.

I had hoped that, if I specified a port block in the client IP filters section, I would see firewall log entries, if a system on the inside of the router attempted to access a system on the outside on a blocked port. Alas, no entries appear in the firewall log in such cases. For me, that makes the firewall logging capability provided by the router too limited to be of much value. I'd have to put a real firewall in front of it.

And for rating its security, you can access a lot of information from the router without even logging into it. If you use your web browser to access the router you can see the following information without logging into the router:

If the router is going to be used strictly for home use, making that information so readily available may not be a big concern, since, hopefully, family members connected by cables to the router can be reasonably trusted. Hopefully, wireless protection has been activated, so that no one can easily access the device, since providing all of that information so readily then could make an attacker's job much easier.

In addition to the lack of logging functionality, I have concerns regarding the router's reliability. I replaced it at my mother-in-law's house after she had some problems printing via the wireless interface in her laptop. I traced the problem to the Belkin router not responding. Powering the router off and on resolved the problem, but this happened a couple of times and I thought it best to replace the router. I also encountered problems with the router not responding when I tested it. The problems occurred within just a few minutes of testing. While logged into the router from a system on the LAN side, I tried accessing it from the WAN side from a system permitted to manage the router. I wanted to see what be logged if I entered the wrong password from that system. Well, the router simply stopped responding completely. I couldn't even ping it from either the WAN or LAN side. It wouldn't provide IP addresses via DHCP and it was no longer accessible from either the LAN or WAN side by HTTP. I had to power the router off and on. I tried again with the same results. Even for a router designed primarily for home use, having to power the router off and on frequently could irritate other family members and, if it was used in a small office, users would likely find any tendency to stop responding aggravating.

TransUnion

You can choose to add your name, i.e. opt-in, to such offers, remove your name for 5 years, or remove your name permanently. If you try to remove your name permanently, you will be informed that you have to complete a form you will be sent, so I chose to remove my name for 5 years.

You will be asked to confirm your phone number, name and address and provide your Social Security Number (SSN) and date of birth. The whole process is handled by an automated system and it only took me a couple of minutes to complete it.

When I completed the process, I was informed that my removal request would be completed within 5 business days, but that I might continue to receive offers for several months from companies to which my information had already been provided and that I might also receive offers from companies that had obtained my information by other means. Hopefully, though, I will see a substantial diminution of the daily deluge of junk mail we receive at my house.

You can use the method outlined by Adobe in Set passwords for PDFs to password protect PDF files that you will then email to others.

The article mentions that PDF documents can have two types of passwords:

1. User, aka "document open", password
2. Pemissions, aka "master", password, which provides access controls for the PDF document

To keep unauthorized individuals from viewing a PDF file, employ a "user" password. The other type of password, which you might also want to use in some cases, controls what recipients can do with a document.

Note: there are low-cost tools readily available online to remove that type of password from a PDF file. There are also low-cost programs readily available to defeat the first type of password unless you pick a strong password, i.e. one that is not a dictionary word, car name, sports team, person's name, etc. There are plenty of password dictionaries available to allow people to crack weak passwords. Any password protection scheme is virtually worthless, if someone picks a weak password. A strong password should have at least 8 characters with a combination of characters from at least 3 character sets. Character sets include those below:

1. Upper case letters
2. Lower case letters
3. Numbers
4. Special characters, such as "!", "-", "_", "$", etc.

Open the file you want to protect in Adobe Acrobat and follow the instructions below for encrypting and password protecting the file.

1. Click the secure button in the Tasks toolbar and choose Password Encrypt.
2. Click on Yes when prompted "Are you sure you want to change the security on this document?" If necessary, type the Permissions password that lets you change security settings. If you don't know the password, contact the author of the PDF file.
3. In the Password Security - Settings dialog box set the security options as desired. For the Compatibility setting, "Acrobat 5.0 or later" is the default option. That will provde 128-bit RC4 encryption. Selecting "Acrobat 3.0 or later", instead, will mean that users of older versions of Acrobat will be able to open the file, if they know the password, but I would strongly advise against choosing that option, if you need to guarantee that only someone who has been given the password can open it. If that option is selected, a 40-bit encryption scheme is used instead of 128-bit encryption. Even with a strong password, if you use 40-bit encryption, there are plenty of low-cost programs available online for anyone to easily break the password protection. With 128-bit protection, you can be confident that the protection will likely remain unbreakable for years to come (eventually increases in computing speeds, or the development of quantum computers, will likely render even that level of encryption breakable).
4. Specify a password, click OK and then OK again.
5. Save the file

Note: these instructions were written specifically for Adobe Acrobat 8 Standard edition, but will likely be similar for other versions.

The screen saver for the hidden account is set to the "Windows XP" screen saver with "On resume, display Welcome screen" checked.

At Hide user accounts from the Windows XP Welcome screen, one can download a tool that makes it easy to hide and unhide accounts. The webpage also mentions that the Ctrl-Alt-Del trick for logging into hidden accounts has a a pitfall - "it will fail to work if a user is still currently logged in."

If I hit Ctrl-End, the cursor is placed in the passwod field for one of the visible accounts, but hitting Ctrl-Alt-Del at that point has no effect and I can't get back into the logged in account.

I've found I can get around this problem by logging into one of the visible accounts and then immediately logging off that account. If I then hit Ctrl-Alt-Del a couple of times, I get the "Log On to Windows" user name and password prompt and can regain access to the hidden account under which I'm already logged in.

After modifying the httpd.conf file, I restarted Apache with /usr/local/apache2/bin/apachectl restart. For a Linux system apachectl restart should suffice, though it is likely located in /usr/sbin, if you need to specify the full path.

After restarting Apache I was able to configure a browser on the system at the 192.168.1.4 address to use the Apache server as a proxy server. I used the IP address of the Apache server, 192.168.1.1 as the HTTP proxy server address with 80 as the port. I verified that the browser was using the Apache server as a proxy server by pointing the browser on the 192.168.1.4 system to www.showmyip.com. That site showed the address for the system as 192.168.1.1, i.e. it showed the connection as originating from the proxy server rather than the actual system on which the browser was being used.

I was also still able to access webpages on the website I host on the Apache server on the default HTTP port.

If you want to turn the proxy service off, you need only change the ProxyRequests On line to ProxyRequests Off and restart Apache.

Chances are that you are reading this because you found a reference to this web page from your web server logs. This reference was left by Turnitin.com's web crawling robot, also known as TurnitinBot. This robot collects content from the Internet for the sole purpose of helping educational institutions prevent plagiarism. In particular, we compare student papers against the content we find on the Internet to see if we can find similarities. For more information on this service, please visit www.turnitin.com

The Wikipedia article on Turnitin states that it is as "an Internet-based plagiarism-detection service created by iParadigms, LLC. Institutions (typically universities and high schools) buy licenses to submit essays to the Turnitin website, which checks the document for plagiarism."

I had read that many schools now use such services to deter students from submitting plagiarized papers. I've seen services offerring pre-written papers for students to submit for classes, so I can see the need for teachers to use such detection services. I didn't realize this service crawled websites to index materials on the web as part of its detection efforts, but it makes sense to me that the service would do so. This is the first time I've noticed this particular web crawler

I ran yum install ethereal, which installed wireshark and its dependency, libsmi. Wireshark was installed, because development of ethereal has stopped and the core development team is now developing wireshark.

The FAQ for wireshark offers the following explanation of the name change.

In May of 2006, Gerald Combs (the original author of Ethereal) went to work for CACE Technologies (best known for WinPcap). Unfortunately, he had to leave the Ethereal trademarks behind.

This left the project in an awkward position. The only reasonable way to ensure the continued success of the project was to change the name. This is how Wireshark was born.

Wireshark is almost (but not quite) a fork. Normally a "fork" of an open source project results in two names, web sites, development teams, support infrastructures, etc. This is the case with Wireshark except for one notable exception -- every member of the core development team is now working on Wireshark. There has been no active development on Ethereal since the name change. Several parts of the Ethereal web site (such as the mailing lists, source code repository, and build farm) have gone offline.

After the installation completed, I tried running wireshark by issuing the command wireshark.

# wireshark
bash: wireshark: command not found

I then discovered that installing the wireshark RPM only installs a command line program, tshark. The program was installed in /usr/sbin/tshark. You can obtain help on tshark using man tshark or tshark -h. There is also documentation installed in /usr/share/wireshark/help.

I had to install wireshark-gnome to get the GUI version, which I did with yum -y install wireshark-gnome. I could then start the GUI version from a shell prompt with wireshark or start it by clicking on Applications, Internet, and then Wireshark Network Analyzer.

Since I wanted to capture only HTTP traffic, I typed HTTP in the Filter field and then clicked on the Apply button. I then clicked on Capture, Interfaces, and clicked on the Start button next to the eth0 interface to start capturing all HTTP traffic.

SquirrelMail is installed in /usr/share/squirrelmail. The configuration files are installed in /etc/squirrelmail.

# ls /etc/squirrelmail
config_local.php  config.php  default_pref  sqspell_config.php

After the software was installed I ran the configuration script to configure SquirrelMail.

# /usr/share/squirrelmail/config/conf.pl

When I ran the configuration script, I saw the following menu:

SquirrelMail Configuration : Read: config.php (1.4.0)
---------------------------------------------------------
Main Menu --
1.  Organization Preferences
2.  Server Settings
3.  Folder Defaults
4.  General Options
5.  Themes
6.  Address Books
7.  Message of the Day (MOTD)
8.  Plugins
9.  Database
10. Languages

D.  Set pre-defined settings for specific IMAP servers

C   Turn color off
S   Save data
Q   Quit

Command >>

I typed D and hit Enter to configure SquirrelMail for a specific IMAP server. In this case, I'm running dovecot on the server, which is one of the IMAP servers for which the configuration script can optimize SquirrelMail's settings.

SquirrelMail Configuration : Read: config.php
---------------------------------------------------------
While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others.  If you select your IMAP server, this option will
set some pre-defined settings for that server.

Please note that you will still need to go through and make sure
everything is correct.  This does not change everything.  There are
only a few settings that this will change.

Please select your IMAP server:
    bincimap    = Binc IMAP server
    courier     = Courier IMAP server
    cyrus       = Cyrus IMAP server
    dovecot     = Dovecot Secure IMAP server
    exchange    = Microsoft Exchange IMAP server
    hmailserver = hMailServer
    macosx      = Mac OS X Mailserver
    mercury32   = Mercury/32
    uw          = University of Washington's IMAP server

    quit        = Do not change anything
Command >>

I typed dovecot and hit Enter to configure SquirrelMail for the dovecot IMAP server. I was then shown the configuration options set for dovecot.

              imap_server_type = dovecot
         default_folder_prefix = 
                  trash_folder = Trash
                   sent_folder = Sent
                  draft_folder = Drafts
            show_prefix_option = false
          default_sub_of_inbox = false
show_contain_subfolders_option = false
            optional_delimiter = detect
                 delete_folder = false

Press any key to continue...

When I hit a key, I was returned to the main menu. I typed S and hit Enter to save the settings. I was informed "Data saved in config.php". I then typed Q and hit Enter to exit from the configuration script.

The system runs the Apache webserver, so I then restarted the Apache server with apachectl restart.

During the installation, the file /etc/httpd/conf.d/squirrelmail.conf is created. The file contains the following lines:

#
# SquirrelMail is a webmail package written in PHP.
#

Alias /webmail /usr/share/squirrelmail

The web interface for SquirrelMail can be accessed at http://a.example.com/webmail [substitute the actual name for your server for a.example.com]. You should see a login page where you can login to check email.

You can also test the SquirrelMail configuration using http://a.example.com/webmail/src/configtest.php [again, substitute your actual domain name for a.example.com]. When that page is displayed, you will see configuration information. The script will try to check some aspects of your SquirrelMail configuration and point you to errors whereever it can find them. You need to have run conf.pl in the config/ directory first, as I mentioned above, before you run this script. At the bottom of the webpage that is displayed, you should see "Congratulations, your SquirrelMail setup looks fine to me!"

You have exceeded the size limit on your mailbox. You can find types of items to delete or move, empty the deleted items folder, or you can have Outlook transfer items to an archive file.

I had to delete copies of messages he forwarded multiple times and archive some messages to bring the mailbox size below 2 GigaBytes (GB) [See Outlook 2003 Mailbox Size Exceeded].

I also checked the size of all other users' mailboxes on the Microsoft Exchange 6.5 server that processes his email. [See Determining Mailbox Size for All Exchange Users]

The "line too long" messages are normal for this MUSH and don't impact the functioning of the MUSH. The first unexpected message I see is the line below:

*** glibc detected *** ./bin/netmush: double free or corruption (top): 0x000000000c2076f0 ***

The line in the Startmush file that was producing the error message is shown below:

$BIN/netmush $make_db -c $GAMENAME.conf -l $LOGNAME -p $PIDFILE -t $TEXT -b $BIN -d $DATA -g $GDBM_DB -k $CRASH_DB >>$LOGNAME 2>&1 &

I suspected the problem might be related to the fact that I'm running the MUSH on a 64-bit version of CentOS now. It was previously installed on a 32-bit Red Hat 9 Linux system. I remembered encountering problems when I initially moved it to the CentOS system in April, related to the fact that the CentOS system was a 64-bit operating system. Unfortunately, I can't remember exactly how I resolved the problems I encountered then.

When I performed a Google search on "glibc double free or corruption 64-bit", one of the pages I found, glibc detected double free or corruption error? had a posting by RavenOfOdin that offered a solution:

Re: glibc detected double free or corruption error?

That's an old Linux C++ error. Not new news.
To fix it so you can run the program just type:

export MALLOC_CHECK_=0

before running the program.

So I entered the command export MALLOC_CHECK_=0 from a BASH shell prompt before the Startmush command. It solved the problem and the MUSH started as before the crash. I don't remember entering that command previously to get the MUSH to run, but since it did fix the problem, I thought I had better document it for the next time I encountered the problem.

$ export MALLOC_CHECK_=0
$ ./Startmush

I put the drive in a desktop system and booted that system from one of the Ghost 2003 CDs I had tried with the laptop. I didn't receive any error messages and was able to back up the drive without any problems, so I'm not sure why I received the error message when attempting the backup with the laptop.

I know that sometimes a CD or DVD drive will have problems with discs from a particular manufacturer, so perhaps the external HP DVD ROM drive (p/n: PA509A#ABA) was having a problem reading the Office Depot CD-R discs I had put Ghost on, but that shouldn't have any bearing on Ghost aborting when I tried to start it to backup the disk drive. I was able to boot the laptop using the external DVD-ROM drive with an Ubuntu Linux LiveCD.

The blog uses a Blosxom Calendar plugin.

I remembered having problems when I moved the blog from a 32-bit Linux system to a 64-bit system (see Blosxom Calendar Plugin on 64-bit System). I found the problem was similar and I was able to resolve it by deleting the .calendar.cache file from the Blosxom plugins state directory, plugins/state.

Once the blog was accessible again, I checked the state directory with ls -al again and saw the .calendar.cache file had been recreated.

Write protect error writing drive A
Abort, Retry, Fail?

I would hit F and the boot process would proceed. If I hit R, I would get the same message again. Hitting A for "Abort" would allow me to proceed to running Ghost, but the mouse driver wouldn't load. If I hit F8 just as I was booting from the Ghost 2003 boot CD, I could walk through the commands in config.sys and autoexec.bat, which allowed me to see that the error occurred just as the mouse driver was being loaded.

I didn't know how to eliminate the error until I found the cause of the problem described by eASYkILL in a posting at Ghost 2003 Multi-Boot CD (Abort,Retry,Fail) error. He posted the following information:

So here is the deal... MOUSE.COM is trying to create a MOUSE.INI file and because you created a bootable CD (read-only) it is unable to write the file and gives the error message (Abort, Retry, Fail). If you fail, you can continue just fine with mouse support.

The solution... add a MOUSE.INI to your floppy that you are creating the image from. If you booted from the floppy at least once, this problem doesn't occur because the file is created. That may be how it went away for you. Just re-create the bootable CD from the floppy with mouse.ini added.

Here is my mouse.ini

[mouse]
MouseType=PS2

Cheers!

Since most of the systems on which I'm performing the Ghost 2003 image backups have a mouse attached by the PS/2 mouse port, I thought that should work fine. So I used Notepad to create a mouse.ini file with the above lines on one of the Ghost 2003 boot floppy disks (be sure to change the "save as type" to "all files", if using the Windows Notepad program). I also found that I was able to boot laptops with a built-in mouse touchpad and use use the mouse with no problems with the mouse type set to PS2 in mouse.ini. I no longer received the "Abort, retry, or fail" message when booting from a Ghost 2003 boot CD that had the mouse.ini file in the root directory.

Note: you can see optons for the mouse.com program by typing mouse /? at a command prompt. You can use mouse off to remove the mouse driver from memory.

mouse type       /Cn (serial), /Z (PS2), /In (inPort), /B (bus)
                  (n specifies a prot and can be either 1 or 2)

I followed the instructions at How to Mount an NTFS Filesystem in order to be able to do so. I issued the command yum install fuse fuse-ntfs-3g dkms dkms-fuse to install the required packages (dkms and dkms-fuse install the fuse kernel module).

The system needs to be configured to use the RPMforge repository in order for the above yum install command to work. See Installing Wine on CentOS or RPMForge Packages and Yum Priorites for information on configuring yum to use the RPMforge repository.

After installing the ntfs-3g driver, I was able to mount the NTFS-formatted drive.

[root@localhost ~]# mkdir /mnt/windrive
[root@localhost ~]# mount -t ntfs-3g /dev/sda1 /mnt/windrive

I first created a mount point, which I arbitrarily named "windrive" under /mnt. Then I needed to specify the file system type with -t ntfs-3g. This particular drive was an external USB drive, which Linux identified as /dev/sda. It had only one partition on it, so I used /dev/sda1 to mount it. If you are unsure how Linux will identify the drive, see Linux Drive Designations

If the NTFS drive contains the Windows operating system for a system and the system was put into hibernation mode when it was shut down, you can only mount it in read-only mode. You will see the following message, which I saw when I tried to mount another drive from a hibernated Windows system, if you don't specify read-only mode for mounting the drive:

# mount -t ntfs-3g /dev/sdc1 /mnt/workdrive
Windows is hibernated, refused to mount.
Failed to mount '/dev/sdc1': Operation not permitted
The NTFS partition is hibernated. Please resume and shutdown Windows
properly, or mount the volume read-only with the 'ro' mount option, or
mount the volume read-write with the 'remove_hiberfile' mount option.
For example type on the command line:

            mount -t ntfs-3g /dev/sdc1 /mnt/workdrive -o remove_hiberfile

I was able to mount the drive by using the -r option for the mount command (you can also use -o ro).

mount -r -t ntfs-3g /dev/sdc1 /mnt/workdrive

Summary     : Linux NTFS userspace driver
Description :
The ntfs-3g driver is an open source, GPL licensed, third generation Linux NTFS
driver. It provides full read-write access to NTFS, excluding access to
encrypted files, writing compressed files, changing file ownership, access
right.

Technically it’s based on and a major improvement to the third generation Linux
NTFS driver, ntfsmount. The improvements include functionality, quality and
performance enhancements.

ntfs-3g features are being merged to ntfsmount. In the meanwhile, ntfs-3g is
currently the only free, as in either speech or beer, NTFS driver for Linux
that supports unlimited file creation and deletion.

After unmounting the drive with the umount command, I removed the directory I created when mounting it.

[root@localhost /]# rmdir /mnt/windrive

Summary     : plugin to give priorities to packages from different repos
Description :
This plugin allows repositories to have different priorities.
Packages in a repository with a lower priority can't be overridden by packages
from a repository with a higher priority even if repo has a later version.

I then verified that yum-priorities is enabled by ensuring that the following lines were present in /etc/yum/pluginconf.d/priorities.conf :

[main]
enabled = 1

The yum repository information is stored in /etc/yum.repos.d.

[root@localhost ~]# ls -l /etc/yum.repos.d
total 32
-rw-r--r-- 1 root root 2049 Jun 19 09:48 CentOS-Base.repo
-rw-r--r-- 1 root root  626 Jun 19 09:48 CentOS-Media.repo
-rw-r--r-- 1 root root  684 Mar  8  2007 mirrors-rpmforge
-rw-r--r-- 1 root root  428 Mar  8  2007 rpmforge.repo

I added priority=1 as the last line in the following sections of CentOS-Base.repo:

[base]
[updates]
[extras]

I added priority=2 as the last line in the [centosplus] .

I edited /etc/yum.repos.d/rpmforge.repo and added priority = 11 at the end of the file.

Repositories with lower priority numbers are considered to have a higher priority than than those with higher numbers. E.g. if repository A has priority=4 associated with it while repository B has priority=5 associated with it, repository A has a higher priority than repository B.

After adding the RPMForge repository, I was then able to install Wine with yum install wine. The following dependencies were also instaled:

After the installation, I ran winecfg.

Wine was configured to emulate Windows XP by default. I clicked on the Desktop Integration tab and set the "My Documents", "My Pictures", "My Music", and "My Videos" folders to link to directories I created under a "Documents" folder, I created under the login directory for the account I was logged in under. The directories must be created before you link to them with the Wine configuration utility.

[root@localhost Documents]# mkdir Pictures
[root@localhost Documents]# mkdir Music
[root@localhost Documents]# mkdir Videos

In the Wine configuration window, I clicked OK to retain the default settings. When I was returned to the shell prompt, I ran wine notepad to test Wine with the notepad application.

There is also a link in the article to a Windows 7 compatibility checker, if you are interested in determing whether a system will be able to support the next version of Windows.

One of the alternatives is OpenOffice. Though I use Microsoft Office on my Windows laptop, I use OpenOffice on other systems, such as Linux or Solaris systems and even on one Windows system. I've found it quite useable and, for most of the documents I work with, able to handle documents created in Microsoft Office's applications fairly well.

I also use Google Docs, though just the spreadsheet capability. I use Google Docs spreadsheets for personal use, such as tracking my mileage and gas consumption. It works fine for that and could also suffice for others with uncomplicated spreadsheet requirements, but it definitely isn't on a par with Microsoft Excel's capabilities.

I haven't tried the other alternative discussed in the article yet, Zoho. Zoho is a suite of online applications (services) that you access from the Zoho website. The applications are free for individuals and some have a subscription fee for organizations. In their FAQ, Zoho states that "We assure you that the contents of your Account will not be disclosed to anyone and will not be accessible to employees of AdventNet.

NTBackup backs up files to a proprietary BKF format. With Windows XP and later, it can even backup open files using Volume Shadow Copy, aka Volume Snapshot Service (VSS)..

To create a backup process that runs every week on a specific day to backup a folder on a system, you can create a batch file similar to the following:

@echo off

REM NTBackup batch file for ACCI folder

REM Set date variable
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set date=%%a-%%b-%%c)
date = %date%

ntbackup backup D:\ACCI /J "ACI" /V:No /M Normal /Snap:on /f "F:\ACI\Backups\Current\ACCI_Weekly_%date%.bkf"

The above batch file, which I've named acci-weekly.bat will backup the D:\backup on the system on which it is run. The files will be backed up to F:\ACI\Backups\Current\ACCI_%date%.bkf. The %date% variable is set by the code below:

For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set date=%%a-%%b-%%c)
date = %date%

The %a variable holds the month, %b holds the day, and %c holds the year. Files will be created with names in the form ACCI_Weekly_07-12-2008.bkf.

The other parameters used are as described below:

/J {"JobName"}
Specifies the job name to be used in the backup report. The job name usually describes the files and folders you are backing up in the current backup job.

/V:{yes | no}
Verifies the data after the backup is complete.

/M {BackupType}
Specifies the backup type. It must be one of the following: normal, copy, differential, incremental, or daily.

/SNAP:{on | off} Specifies whether or not the backup should use a volume shadow copy.

/F {"FileName"}
Logical disk path and file name. You must not use the following switches with this switch: /P /G /T.

Further information on the options availabe with the ntbackup command can be obtained by running ntbackup /? from a command prompt.

By specifying normal as the backup type, all of the files in the folder will be backed up. If the folder occupies a large amount of disk space and will take a considerable amount of time to backup, you may not want to backup all of the files every day.

In this case I would run a normal backup on Sundays, but an incremental backup every other day. So I have a second batch file, acci.bat.

@echo off

REM NTBackup batch file for ACCI folder

REM Set date variable
For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set date=%%a-%%b-%%c)
date = %date%

ntbackup backup D:\ACCI /J "ACI" /V:No /M Incremental /Snap:on /f "F:\ACI\
Backups\Current\ACCI_%date%.bkf"

To run the batch file that performs the incremental backup every day, you can use the at command.

C:\Documents and Settings\Administrator>at 19:30 /every:m,t,w,th,f,s d:
\backups\acci.bat
Added a new job with job ID = 1

The above command schedules the backup to run every night, Monday through Saturday, at 7:30 P.M. The backup is an incremental backup. An incremental backup is a backup that copies only those files created or changed since the last normal or incremental backup. It marks files as being backed up by clearing the archive attribute on files. If you use a combination of normal and incremental backups to restore your files, you will need to have the last normal backup and all incremental backup sets.

You can check scheduled jobs by running the at command with no parameters. You can get help on the command with at /?.

C:\Documents and Settings\Administrator.mayberry>at
Status ID   Day                     Time          Command Line
-------------------------------------------------------------------------------
        1   Each M T W Th F S       7:30 PM       d:\backups\acci.bat

To schedule the job that runs once a week on Sunday, I can use at 19:30 /every:su d:\backups\acci_weekly.bat.

For a full restoral from the backups, I would need to restore first from the weekly normal backup and then restore from each of the incremental backups from that week.

I saw that the initialization failed.

The event details showed that the client timed out.

A Ghost client system should be listening on UDP port 1346. The Ghost server sends a datagram from UDP port 1347 to port 1346 on the client to start the backup. But when I scanned the client system with Foundstone's free ScanLine program, I found it wasn't responding on port 1346.

And when I examined the network traffic between the two systems with MicroOLAP's tcpdump when I ran the backup task, I saw the client system was returning a "udp port 1346 unreachable" message.

I logged onto the system from the server using the Remote Desktop Protocol (RDP). When I logged on and checked whether the system was listening on UDP port 1346 with netstat, I saw it was listening.

C:\Documents and Settings\Administrator>netstat -a | find "1346"
  UDP    Ellie:1346             *:*

When I disconnected and scanned the system from the Ghost server again using ScanLine, I could then see it was responding on UDP port 1346. Apparently just logging on to the system caused it to start accepting data on port 1346 again.

But when I ran the Ghost task again, it again failed. And when I scanned the system with ScanLine again, I found the client system was no longer responding on port 1346. And when I checked from the system itself by using the netstat command again, I found netstat was no longer showing it listening on port 1346.

From the client system itself, I ran ngctw32.exe, which is located in C:\Program Files\Symantec\Ghost. When I ran ngctw32, the ScanLine program showed it listening on port 1346 as did netstat. I then reran the Ghost task from the server. This time the backup started.

The hosts file is at c:\windows\system32\drivers\etc\hosts. In this case Windows Defender is flagging it because it has been modified. Typically, it doesn't have much more in it than a reference to the loopback address, i.e. 127.0.0.1 localhost.

In the case of this laptop, Spy Sweeper added entries such as the following:

127.0.0.1 localhost
127.0.0.1 1.httpdads.com #SpySweeperCASS
127.0.0.1 207-87-18-203.wsmg.digex.net #SpySweeperCASS
127.0.0.1 a.mktw.net #SpySweeperCASS
127.0.0.1 a.tribalfusion.com #SpySweeperCASS

Many antispyware programs, such as Spy Sweeper or Spybot Search & Destroy, will add entries to the hosts file, pointing the address to malicious sites or those that distribute adware/spyware to the loopback address, 127.0.0.1, instead. That ensures that if the the system attempts to contact one of those sites, such as httpdads.com , which is listed by SpySweeper, which is antispyware software produced by Webroot Software, Inc., that instead of going to the website distributing the malware, the system instead is directed to the local loopback address on the system itself, preventing the system from contacting the actual website.

So, in this case, I can consider the report a "false positive" and instruct Windows Defender to ignore it.

file:///M:/attach/Pulte%25%20Contact%25%20Information.xls

When I double-clicked on the attachment, I saw the following error message.

A percent sign followed by 20, i.e. %20, is often used to represent a space in filenames within HTML documents, but I didn't know why %25%20 was appearing.

At Corrup path to mail attachments: includes %2520, I found someone reporting a similar problem. A respondent to the original poster provided the following comment:

This happens only when you "use Microsoft's viewer," which means that every email window is actually an Internet Explorer window, in which spaces are not allowed in URLs.

%25 itself represents the character "%" - so after one interpretation by the browser, %2520 becomes %20, which when interpreted a second time represents one space.

However, I get only forward slashes [/] in my paths when using this mode, which also begin with file:///C:/... [three initial forward slashes]

When not "using Microsoft's viewer," then you get backward slashes [\] and the path is file://C:\... [with no %, just spaces]

That described what I saw. I saw forward slashes for the full directory path when I hovered the mouse over the attachment name, but backslashes were listed in the error message that appeared.

Someone else suggested unchecking "Use Microsoft Viewer" in "Tools|Options|ViewingMail". I clicked on Tools, Options, and selected Viewing Mail. I saw the following:

I unchecked "Use Microsoft's viewer". After closing and reopening Eudora, I was then able to view attachments with spaces in the filenames by double-clicking on them. I noticed that Eudora was now displaying backslashes in the filenames, which is the convention used by Microsoft Windows, when I moved the mouse over them instead of the forward slashes it showed previously.

I've used Office Depot's recycling program. You can buy boxes in several different sizes into which you can place electronic items to be recycled. You bring the boxes back to the store where someone checks that the items they contain are on the list of those that Office Depot states they will recycle when you buy the boxes. The cost of the boxes depends on their size. A small box is $5, a medium one is $10, and a large one is $15. Details on the program are available at Tech Recycling Services.

Staples also has a recycling program. Details on their program can be found at Staples Soul - Recycling. According to the Staple's website, "A recycling fee of $10 per piece of large equipment is charged to cover handling, transport, product disassembly and recycling. Smaller computer peripherals such as keyboards, mice, and speakers are accepted at no charge."

Engadget has information on other recycling services at http://www.engadget.com/tag/recycling, including information on a U.S. Postal Service recyling program where the Postal Service allows you to ship items to a recycling company for free.

Another service I found mentioned in comments to a June 2, 2008 engadget article, Staples to stock Flexplay self-destructing DVDs was GreenDisk. GreenDisk recycles the following items:

• All forms of electronic media and their cases: diskettes, zip disks, CDs, CD-Rs, CD-RWs, DVDs et al, video tape (i.e. VHS), audio tape, game cartridges, DAT, DLT, Beta or Digibeta, and virtually all other type of computer tapes.
• Hard drives, Zip and Jazz drives, jump drives, etc.
• All forms of printer cartridges including both inkjet and toner.
• All types of cell phones, pagers, PDAs and their chargers, cables, and headset accessories
• All types of rechargeable batteries (not regular alkaline ones) and their chargers
• All of the small computer accessories such as MP3 players, iPods, digital cameras, hand-held scanners, handheld games and other connected devices.  (Technotrash Can Only)

According to the article, Amazon's founder, Jeff Bezos, has said that there are 125,000 books available for the Kindle. I didn't know it also could allow you to surf the web or listen to music in MP3 form. One of those posting comments to the article stated the following:

Frank - the Kindle can check e-mail, surf the web, & play mp3s. The browser still needs some work but it is usable. Internet service is free and at decent speeds as long as you are in a Sprint service area. The Kindle is definitely a niche device but could become more mainstream with some changes, primarily price & a larger screen. IMO it's not as ugly in real life as the pictures represent on the web but could use a better design. I have a few other quibbles with it but have no regrets in buying one.

I looked for a pcal RPM package. I found that the perl-Calendar-Simple package contained a pcal program and decided to install it. I installed the package, which is available from http://packages.sw.be/perl-Calendar-Simple/ or RPM PBone. If you are using the RPMforge repository, you can install it with yum or another installer. To configure yum to use the RPMForge repository, see RPMForge Packages and Yum Priorites.

# yum install perl-Calendar-Simple

After I installed the package, I found it installed /usr/bin/pcal. That pcal program was a Perl script. I could use it to generate the current month's calendar by typing pcal or a specific month from the current year with pcal m, where m is a number representing a month, e.g. pcal 6 would display the month of June. Or you can use pcal mm, e.g. pcal 06 for June. That pcal can also generate a calendar for a specific month and year with pcal mm yyyy, e.g. pcal 06 2009 for the calendar for June 2009.

# pcal 06 2009

21 22 23 24 25 26 27
28 29 30

But that pcal program didn't offer me as many options as I had with the cal program that was already installed on the system. I didn't need anything particularly fancy, but I did need the capability to generate a calendar in HTML format, which the Perl pcal script didn't provide.

I opened the .csv file in Excel and used the proper() function to perform the conversion. Excel provides 3 functions, upper, lower, and proper to change the case of text.

Example: JOHN Smith is in cell A1 of an Excel worksheet

=UPPER(A1) will change the text to all uppercase, i.e. JOHN SMITH

=LOWER(A1) will change the text to all lowercase, i.e. john smith

=PROPER(A1) will change the case to suit a proper name, i.e. John Smith

There were about 1,500 entries in the worksheet, so I didn't want to type a formula in each cell. Instead, I created another column immediately to the right of the one containing the name by clicking on Insert then Columns in Excel. The first cell containing a name was B2. In C2, I put the formula =proper(b2). Then I clicked in the C2 cell to select it. I then held the left mouse button down and extended the highligted area down to the last row containing a name. Since the last such row was row 1482, I highlighted cells C2 through C1482. When I had all of the cells highlighted, I released the mouse button. I then hit Ctrl-D to copy the formula down through all of the higlighted cells (the formula is automatically incremented as it is copied). That resulted in the following formulas in column C.

I then resaved the file in csv format and closed it. I then reopened it in Excel. Since it was saved in CSV format, column C had the names with the correct capitalization now without any formula attached to them. I then deleted column B, which had the names in all capital letters. I then resaved the file.

Note: If you have a name in the form "JOHN S SMITH III", proper will convert the name to "John S Smith Iii", so you may need to scan through the list of names for such instances.

If you are attempting to send an email message using Eudora and you see a message similar to the one below, then the SMTP server that Eudora has been configured to use for outgoing email likely requires authentication.

Can't send to 'someone@example.com'. The server gives this reason: '550 5.7.1
<someone@example.com>... Relaying denied. Proper authentication required.'.

Version 4.2.2 of Eudora supports authentication when sending email. If you have a Windows 4.x version of Eudora, you can upgrade it to version 4.2.2 by downloading ep4xto422.exe from the updater422 folder on the Qualcomm FTP site. Version 4.2.0 doesn't support authenticating when sending email, though the help files indicate that it does, according to Eudora Pro 4.x - SMTP Auth . If you don't know which version of Eudora you are running, you can click on Help and then About in Eudora. You should see "Version 4.2.2" for that version.

To enable authentication when sending in Eudora 4.2.2, you must edit the eudora.ini file. Close Eudora, if it is open, and add the following two lines below the [Settings] line in eudora.ini file.

SMTPAuthRequired=1
SMTPAuthAllowed=1

Then, when you reopen Eudora, SMTP authorization should be enabled.

Note: there are different methods of authenticating with an email server. If you see a message similar to the following, the email server does not support the authentication method used by Eudora.

<Dominant>, Connecting to the Mail Server..., [05:24:13 PM]
Can't find a supported authentication mechanism for sending messages, and you've
specified to require authentication.

For instance, Eudora 4.2.2 doesn't support the Plain and Login methods.

You can determine which authentication methods a server supports by using telnet to connect to port 25 on the server, which is the standard SMTP port. After you issue an HELO or EHLO command and some name for the system from which you are connecting, e.g. "laptop" or "mysystem.example.com", you should see AUTH listed as one of the commands the server understands with the authentication methods it supports listed immediately after AUTH on the same line.

250 HELP

In the example above, the email server only supports the LOGIN and PLAIN methods, which resulted in Eudora complaining that it "Can't find a supported authentication mechanism for sending messages, and you've specified to require authentication."

According to Negotiating an SMTP AUTH Authentication Mechanism, "The standard Eudora client (downloadable from www.eudora.com) tries to use CRAM-MD5 by default."

If an email server supports CRAM-MD5 and DIGEST-MD5, you would see the following, if you connected to port 25 on the server, after you issued an helo or ehlo command..

# file mime.types for specific file types.

After the packages were installed, I check the ClamAV definitions with the freshclam command.

# freshclam -V
ClamAV 0.93/6688/Wed Apr  9 10:40:38 2008

I verified that the version of sendmail on the system provides milter support with sendmail -d0 < /dev/null | grep MILTER. If sendmail provides milter support, MILTER will be listed in the output. Sendmail 8.13 enables MILTER support by default. See Clam AntiVirus Milter Setup and Debugging for details on how to add MILTER support for prior versions.

# sendmail -d0 < /dev/null | grep MILTER
                MATCHGECOS MILTER MIME7TO8 MIME8TO7 NAMED_BIND NETINET NETINET6

According to Clam AntiVirus Milter Setup and Debugging, the libmilter* library must be installed on the system to use clamav-milter, so I checked for the presence of libmilter files with locate libmilter, but none were listed. The instructions suggested that if the library is not installed, one should "go to the Sendmail source directory, change into the libmilter subdirectory and run the install script." But there was no sendmail source directory on the system, since sendmail had been installed through a package when I initially set up the system. Since the instructions also stated "Some operating systems provide MILTER support via a port or package", I thought I would just proceed to see what happened.

The next step listed was to configure clamav with --enable-milter . I presumed that was already taken care of when I installed the clamav-milter package, so I proceeded to the "configure clamd.conf" step. I checked /etc/clamd.conf, but didn't make any changes.

The installation of the clamav-milter package placed two files in /etc/init.d.

# ls -l /etc/init.d/clam*
-rwxr-xr-x 1 root root 1258 Mar  7  2007 /etc/init.d/clamav-milter
-rwxr-xr-x 1 root root 1130 Nov  1  2006 /etc/init.d/clamd

It also installed and turned on two system services.

# chkconfig --list clamd
clamd           0:off   1:off   2:on    3:on    4:on    5:on    6:off
# chkconfig --list clamav-milter
clamav-milter   0:off   1:off   2:on    3:on    4:on    5:on    6:off

I started the Clam AntiVirus daemon with /etc/init.d/clamd

# vi /etc/init.d/clamd
# /etc/init.d/clamd start
Starting Clam AntiVirus Daemon:                            [  OK  ]

You then need to configure sendmail for clamav-milter support. If you try launching clamav-milter first, you will get the error shown below:

# /etc/init.d/clamav-milter start
Starting Clamav Milter Daemon: clamav-milter: socket-addr (local:/var/clamav/clm
ilter.socket) doesn't agree with sendmail.cf
                                                           [FAILED]

So I put the following line as the last line in /etc/mail/sendmail.mc

INPUT_MAIL_FILTER(`clamav', `S=local:/var/run/clamav-milter.sock, F=T, T=S:4m;R:4m')

I then rebuilt the sendmail.cf file from sendmail.mc with the following command:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

When I tried restarting sendmail, though, I received a warning message:

# /etc/init.d/sendmail restart

I then looked in /etc/sysconfig/clamav-milter and saw the following:

### Simple config file for clamav-milter, you should
### read the documentation and tweak it as you wish.

CLAMAV_FLAGS="
    --config-file=/etc/clamd.conf

    --local
    --max-children=10
    --noreject
    --outgoing

"
SOCKET_ADDRESS="local:/var/clamav/clmilter.socket"

Since according to the SOCKET_ADDRESS in that file, clmilter.socket was expected in /var/clamav, I modified the line I added to the end of /etc/mail/sendmail.mc to be as shown below:

INPUT_MAIL_FILTER(`clmilter', `S=local:/var/clamav/clmilter.socket, F=T, T=S:4m;R:4m')

I then rebuilt the sendmail.cf file from sendmail.mc, restarted clamav-milter, and restarted sendmail.

# m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
# /etc/init.d/clamav-milter restart

The "failed" for the restart of clamav-milter was probably because it wasn't started at the time; so I could have used clamav-milter start. I also saw an error message regarding "LibClamAV Error: cl_cvdhead: Can't open file /var/clamav/daily.inc/daily.info", but when I sent a test message to an account on another system, I saw "X-Virus-Scanned: ClamAV version 0.93, clamav-milter version 0.93" in the message's headers. I saw the same header in a message I sent from the account on the other system to the one running ClamAV. I also saw the header "X-Virus-Status: Clean". So ClamAV appeared to be scanning incoming and outgoing email.

The sendmail.mc already had the line FEATURE(`blacklist_recipients')dnl. The blacklist_recipients feature turns on the ability to block incoming mail for certain recipient usernames, hostnames, or addresses. For example, you can block incoming mail to user nobody, host foo.mydomain.com, or guest@bar.mydomain.com. These specifications are put in the /etc/mail/access file.

Immediately below that line, I added the following lines to use the McFadden Associates E-Mail Blacklist, the Spamhaus Block List, and the Passive Spam Block List.

FEATURE(`dnsbl', `bl.csma.biz', `550 Spam Block: mail from $&{client_addr} refused - See http://bl.csma.biz/')dnl
FEATURE(`dnsbl', `sbl.spamhaus.org', `550 Spam Block: mail from $&{client_addr} refused - See http://www.spamhaus.org/sbl/')dnl
FEATURE(`dnsbl', `psbl.surriel.com', `550 Spam Block: mail from $&{client_addr} refused - see http://psbl.surriel.com/')dnl

I removed the "dnl" from the beginning of the following line, which "uncomments" the directive, to allow the system to accept email from users who have authenticated by a trusted mechanism defined by TRUST_AUTH_MECH (see Sendmail Authorization for Outgoing Email).

dnl FEATURE(delay_checks)dnl

I didn't want a user's email to be rejected because the user's system received a dynamically assigned IP address previously assigned to a system sending out spam, which I've seen happen previously. By using the delay_checks feature, you can have sendmail skip the check_mail and check_relay rulesets, if the sender has been authenticated by a "trusted" mechanism, such as by sending the user's userid and password to the server when sending email.

I then regenerated the sendmail.cf file from the sendmail.mc file and restarted sendmail with the commands below.

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
/etc/init.d/sendmail restart

The server was running sendmail, which supports SMTP AUTH as defined in RFC 2554 which is based on SASL.

The Cyrus SASL package should be installed to enable sendmail to support the AUTH command for authorization. I checked on whether it was installed with rpm -qi cyrus-sasl. I saw it was installed. I then tried sendmail -d0.1 -bv root | grep SASL and saw NETUNIX NEWDB NIS PIPELINING SASLv2 SCANF SOCKETMAP STARTTLS. The "SASLv2" in the output confirmed that support for SASL was present.

But when I connected to the SMTP port by telnet, I didn't see the AUTH command listed when I issued an ehlo command. And I received messages that the "plain", "login", "cram-md5", and "digest-md5" authorization methods weren't supported when I issued auth commands for those authentication methods.

When I used the testsaslauthd command to check that the saslauthd daemon was installed and running properly, I saw that it was working properly.

# testsaslauthd -s smtp -u jdoe -p HerPassword
0: OK "Success."

You can test SASL support with the testsaslauthd command by specifying a username and its associated password on the system with -u username -p password. The -s service option specifies a particular service. Common service names are "imap", "sieve", and "smtp".

I then looked at /etc/mail/sendmail.mc. I saw define(`confAUTH_OPTIONS', `A')dnl, which provides a list of options for SMTP AUTH was not commented out, so I left it as is. I left the "dnl" at the beginning of the following line, which appeared later in the file. The p option in it would result in sendmail not accepting the PLAIN and LOGIN AUTH methos unless they were protected by a security latyer, such as is provided by STARTTLS.

dnl define(`confAUTH_OPTIONS', `A p')dnl

The sendmail AUTH_OPTIONS options are as follows:

      AuthOptions
                [no short name] List  of  options  for  SMTP
                AUTH  consisting  of  single characters with
                intervening white space or commas.

                    A   Use the AUTH= parameter for the MAIL FROM
                        command only when authentication succeeded.
                        This can be used as a workaround for broken
                        MTAs that do not implement RFC 2554 correctly.
                    a   protection from active (non-dictionary) attacks
                        during authentication exchange.
                    c   require mechanisms which pass client credentials,
                        and allow mechanisms which can pass credentials
                        to do so.
                    d   don't permit mechanisms susceptible to passive
                        dictionary attack.
                    f   require forward secrecy between sessions
                        (breaking one won't help break next).
                    p   don't permit mechanisms susceptible to simple
                        passive attack (e.g., PLAIN, LOGIN), unless a
                        security layer is active.
                    y   don't permit mechanisms that allow anonymous login.

                The first option applies to  sendmail  as  a
                client, the others to a server.  Example:

                    O AuthOptions=p,y

                would  disallow  ANONYMOUS as AUTH mechanism
                and would allow PLAIN and LOGIN  only  if  a
                security  layer (e.g., provided by STARTTLS)
                is already active.  The  options  'a',  'c',
                'd',  'f',  'p', and 'y' refer to properties
                of the selected SASL  mechanisms.   Explana-
                tions  of  these  properties can be found in
                the Cyrus SASL documentation.

I removed "dnl" from beginning of the following 2 lines to uncomment them:

dnl TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
dnl define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

The relevant lines were then as follows:

define(`confAUTH_OPTIONS', `A')dnl
TRUST_AUTH_MECH(`EXTERNAL DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl

I then rebuilt the sendmail.cf file from the sendmail.mc file using m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf. I then restarted sendmail with /etc/init.d/sendmail restart.

When I then used telnet to connect to the SMTP port, port 25, on the server, I saw AUTH listed when I issued the ehlo command.

# telnet 127.0.0.1 25
Trying 127.0.0.1...

# chkconfig --list dovecot
dovecot         0:off   1:off   2:off   3:off   4:off   5:off   6:off

I turned it on so that it would be operational after the next reboot with chkconfig dovecot on.

# chkconfig dovecot on
[root@frostdragon ~]# chkconfig --list dovecot
dovecot         0:off   1:off   2:on    3:on    4:on    5:on    6:off

I then started the service with service dovecot start.

# service dovecot start
Starting Dovecot Imap:                                     [  OK  ]

I could then see that the system was listening on the imap, imaps, pop3, and pop3s ports.

# netstat -a | grep imap
tcp        0      0 *:imaps                     *:*                         LISTEN
tcp        0      0 *:imap                      *:*                         LISTEN
[root@frostdragon archive]# netstat -a | grep pop3
tcp        0      0 *:pop3s                     *:*                         LISTEN

Dovecot can be configured to handle mailboxes for system users, i.e. for accounts on the system or for virtual users. Since the majority of people who would be using the server for email would have no need to log into the system and since I wanted to be able to have john@example.com and john@anotherexample.com, I chose to configure Dovecot for virtual users.

The Dovecot Wiki has this to say about usernames and domains:

Usernames and domains

Dovecot doesn't care much about domains in usernames. IMAP and POP3 protocols currently have no concept of "domain", so the username is just something that shows up in your logs and maybe in some configuration, but they have no direct functionality.

So although Dovecot makes it easier to handle "user@domain" style usernames (eg. %n and %d variables), nothing breaks if you use for example "domain%user" style usernames instead. However some authentication mechanisms do have an explicit support for realms (pretty much the same as domains). If those mechanisms are used, the username is changed to be "user@realm".

And of course there's no need to have domains at all in the usernames.

I followed the instructions in Simple Virtual User Installation. I didn't need to create a dovecot user, since one already existed in /etc/passwd. I did need to create a vmail user account and group, which is used to access the mail for all users.

# grep dovecot /etc/passwd
dovecot:x:97:97:dovecot:/usr/libexec/dovecot:/sbin/nologin
# useradd -u 103 -c Dovecot vmail

The above useradd command created the vmail user and group and automatically created a /home/vmail directory owned by vmail:vmail, under which the email for all users is stored. [Note: you may want to use a UID greater than 500 rather than 103 as in the example above to avoid the problem noted below where the dovecot configuration file by default only permits a UID greater than 500]

I created /var/log/dovecot.log and /var/log/dovecot-info.log and changed the owner and group for those files to vmail.

# touch /var/log/dovecot.log /var/log/dovecot-info.log
# chown vmail /var/log/dove*; chgrp vmail /var/log/dove*;

I then edited /etc/dovecot.conf and changed the settings for the log files.

Original

# Use this logfile instead of syslog(). /dev/stderr can be used if you want to
# use stderr for logging (ONLY /dev/stderr - otherwise it is closed).
#log_path =

# For informational messages, use this logfile instead of the default
#info_log_path =

Modified

# Use this logfile instead of syslog(). /dev/stderr can be used if you want to
# use stderr for logging (ONLY /dev/stderr - otherwise it is closed).
log_path =  /var/log/dovecot.log

# For informational messages, use this logfile 
info_log_path = /var/log/dovecot-info.log

The default line in /etc/dovecot.conf for plaintext authentication is as follows:

#disable_plaintext_auth = no

Since disable_plaintext_auth has a default value of "no", I didn't have to uncomment that line.

I created a directory for the dovecot password file with mkdir /etc/dovecot and then set up a password file in /etc/dovecot/passwd. I changed the protection on the file with chmod 600 /etc/dovecot/passwd, so that only root would have access, since I don't want others with accounts on the system to be able to read the contents of the file. I created entries in the passwd file with entries like the following:

jdoe@example.com:{PLAIN}HerPassword

I then modified the checkpassword section of /etc/dovecot.conf

Original

  # checkpassword executable authentication
  # NOTE: You will probably want to use "userdb prefetch" with this.
  # http://wiki.dovecot.org/PasswordDatabase/CheckPassword
  #passdb checkpassword {
    # Path for checkpassword binary
    #args =
  #}

Modified

  # passwd-like file with specified location
  # http://wiki.dovecot.org/AuthDatabase/PasswdFile
  passdb passwd-file {
    # Path for passwd-file
    args = /etc/dovecot/passwd
  }

I then restarted dovecot with service dovecot restart. I then tested dovecot by using telnet to connect to port 110, the pop3 port, on the system. I could connect to port 110, but didn't get any response to the user and pass commands. I looked in /var/log/dovecot and saw the following errors recorded:

dovecot: May 04 13:35:26 Error: Temporary failure in creating login processes, slowing down for now

dovecot: May 04 13:35:26 Error: child 30455 (login) returned error 127

At Redhat Dovecot error while loading shared libraries: libsepol.so.1: failed to map segment from shared object: Cannot allocate memory, I found a suggestion to edit /etc/dovecot.conf and modify the login_processes_size line so that it is login_process_size = 64. The writer states on that webpage that "This error is not related to shared libraries. You need to set maximum process size in megabytes. If you don't use login_process_per_connection you might need to grow this."

When I looked in /etc/dovecot.conf, I saw the following line:

#login_process_size = 32

I removed the "#" and changed the line to login_process_size = 64 . I then restarted dovecot with service dovecot restart. I no longer saw the error messages in the /var/log/dovecot.log file.

When I again checked email for accounts by using telnet 127.0.0.1 110, I was able to check an account, jsmith, listed in /etc/passwd, but not the jdoe@example.com account listed in the /etc/dovecot/passwd file I created.

When I looked in /etc/dovecot.conf, I saw dovecot: May 04 14:03:20 Error: auth(default): userdb(jdoe@example.com,::ffff:127.0.0.1): user not found from userdb.

I then realized I also needed to modify the "userdb static" section of /etc/dovecot.conf. I made the following changes:

Original

  # static settings generated from template
  # http://wiki.dovecot.org/UserDatabase/Static
  #userdb static {
    # Template for the fields. Can return anything a userdb could normally
    # return. For example:
    #
    #  args = uid=500 gid=500 home=/var/mail/%u
    #
    #args =
  #}

Modified

  # static settings generated from template
  # http://wiki.dovecot.org/UserDatabase/Static
  userdb static {
    # Template for the fields. Can return anything a userdb could normally
    # return. For example:
    #
    #  args = uid=500 gid=500 home=/var/mail/%u
    #
    args = uid=vmail gid=vmail home=/home/vmail/%u
  }

I then restarted dovecot with service dovecot restart. But I still couldn't check email for the virtual user account jdoe@example.com. In the /var/log/dovecot.log file, I saw dovecot: May 04 14:34:19 Error: Logins with UID 103 (user jdoe@example.com) not permitted (see first_valid_uid in config file)

When I checkd the /etc/dovecot.conf, I found the following:

# Valid UID range for users, defaults to 500 and above. This is mostly
# to make sure that users can't log in as daemons or other system users.
# Note that denying root logins is hardcoded to dovecot binary and can't
# be done even if first_valid_uid is set to 0.
#first_valid_uid = 500
#last_valid_uid = 0

I then realized, since I created the vmail account with a UID of 103, that the dovecot configuration file was preventing a login for it, because it was less than 500. I could have changed the first_valid_uid value in dovecot.conf, but I decided to delete the vmail account and its associated home directory and then recreate it with a UID greater than 500. I then restarted dovecot

# userdel vmail
# rm -rf /home/vmail
# useradd -u 502 -c "Dovecot Virtual Users" vmail 
# service dovecot restart

I was then able to check email for both user accounts on the system and virtual user accounts. I saw that dovecot created a /home/vmail/jdoe@example.com directory under /home/vmail.

At this point, though I could login to the POP3 port, port 110, and get dovecot to accept the userid and password for a virtual user, sendmail would return a "user unknow" message, if I tried to send email to a virtual user, because sendmail knew nothing about the dovecot virtual users. So using the instructions in Dovecot LDA with Sendmail as a starting point, I took the steps below.

I created the file /usr/share/sendmail-cf/mailer/dovecot.m4 and put the lines below in it:

######################*****##############
###   DOVECOT Mailer specification                              ###
##################*****##################
Mdovecot,   P=/usr/local/libexec/dovecot/deliver, F=DFMPhnu9,
                 S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP,
                 T=DNS/RFC822/X-Unix,
                 A=deliver -d $u

In /etc/mail/sendmail.mc, I had the following two lines:

MAILER(smtp)dnl
MAILER(procmail)dnl

I added MAILER(dovecot)dnl after those two lines. I then regenerated the sendmail.cf file using the m4 command.

# m4 /etc/mail/sendmail.mc > /etc/mailsendmail.cf

Unfortunately, that did not resolve the issue with virtual users. I still haven't been able to get that working.

1. Login into the firewall using a web browser.
2. Click on Network.
3. Click on Interfaces.
4. For the Untrust interface, click on Edit.
5. In the Properties line at the top of the webpage, you will see VIP. Click on VIP.
6. If you see an Add/Modify VIP Entry field with no VIP services listed beneath it, select "Same as the untrusted interface IP address" and click on Add, otherwise proceed to the next step.
7. Click on the New VIP Service button
8. The Virtual IP field should show the IP address for the Untrust interface. Put the appropriate value in the Virtual Port field, e.g. 110 for POP3. Select the appropriate service for the Map to Service field, e.g "POP3(110)" for POP3. For the Map to IP value, put in the IP address for the internal server for which you want to provide access to this service, e.g. 192.168.10.24, if that was the IP address for the POP3 server behind the firewall.
9. Click on the OK button.

Once the VIP service is configured, you need to set up a new firewall rule, aka policy, to permit traffic from the outside of the firewall through to the inside for this new service.

To do so, take the following steps:

1. Click on Policies at the left side of the webpage.
2. For the From field, select "Untrust" and select "Trust" for the To field.
3. Click on the New button.
4. On the next webpage, put a name of your choosing in the Name field, e.g. POP3 for a POP3 service. You don't need to change the Source Address, but for the Destination Address, select "VIP(untrust)" from Address Book Entry for the Desinstion Address. For Service, you can select "POP3" for this example.
5. If you want logging turned on for this policy, check Logging.
6. If you want "counting" turned on for this policy, click on the Advanced button and then check the Counting checkbox then click on the OK button.

# local-host-names - include all aliases for your machine here.
example.com

Then create the local-host-names.db file with makemap hash /etc/mail/local-host-names < /etc/mail/local-host-names . When you restart sendmail, which you can do with /etc/init.d/sendmail restart, sendmail will then accept email for example.com addresses.

Be aware that if you have an account jsmith which previously would receive email addressed to jsmith@someexample.com, that email addressed to jsmith@example.com will now go there as well.

The steps below can be taken on a Linux system running sendmail to have it send email via a "smart host" server. In essence, instead of the sendmail server sending email directly to other email servers, it transmits all email to another server, the "smart host", which handles the task of transmitting the received email to the recipients' servers.

In /etc/mail/sendmail.mc, look for the following section:

dnl # Uncomment and edit the following line if your outgoing mail needs to
dnl # be sent out through an external mail server:
dnl #
dnl define(`SMART_HOST', `smtp.your.provider')dnl
dnl #

Remove the dnl from the beginning of the dnl define(`SMART_HOST', `smtp.your.provider')dnl line and replace smtp.your.provider with the smart host you will be using, e.g. mail.example.com.

define(`SMART_HOST', `mail.example.com')dnl

In /etc/mail/access add the following line, substituting the actual SMTP server you will need to use for mail.example.com and your actual username and password on the smart host server for myloginname and mypasswd:

Authinfo:mail.example.com "U:myloginname" "P:mypasswd" "M:Plain"

Then regenerate the /etc/mail/access.db file with makemap hash /etc/mail/access </etc/mail/access. Regenerate /etc/mail/sendmail.cf with m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf. Then restart sendmail with service sendmail restart or /etc/init.d/sendmail restart.

Once you have taken the above steps, you can send a test message from the system. Sending one to a test email address on another system that will allow you to view the message headers is ideal. At the destination, look at the message headers for the email you sent. You should see it passing through the smart host.

When I sent out a test message after making the changes above, the message didn't reach the destination. I checked the mail queue with mailq and saw the message had not gone out because of an "AUTH failure".

# mailq
                /var/spool/mqueue (1 request)

                 (Deferred: Temporary AUTH failure)
                                         <melvin@example.com>

I had sendmail attempt to send the queued message immediately and display information on its progress with sendmail -q 0 -v (the -v provides "verbose" information).

# sendmail -q 0 -v

Running /var/spool/mqueue/m43M1HT8032701 (sequence 1 of 1)

In this case I was using smtp.atlanticbb.net as the smart host. I could see it supports an AUTH type of "LOGIN", but I didn't see "PLAIN" listed. I edited /etc/mail/access, replacing "M:Plain" with "M:Login".

Authinfo:smtp.atlanticbb.net "U:myloginname" "P:mypasswd" "M:Login"

I then ran makemap hash /etc/mail/access < /etc/mail/access again. Then when I had sendmail process the mail queue immediately again, the message was successfully transmitted.

Alpine is available through RPMForge, a repository for Linux packages in the RPM format. To install Alpine, I downloaded the rpmforge-release package from RPMforge/Using and then installed it with rpm.

# rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm

That placed two new files, mirrors-rpmforge and rpmforge.repo in /etc/yum.repos.d. I installed the yum-priorities plugin as described in RPMForge Packages and Yum Priorites and set the RPMForge repository to a lower priority than the default CentOS repository.

I installed Alpine with yum install alpine.

First, install the yum-priorities package with yum install yum-priorities. This plugin allows repositories to have different priorities. Packages in a repository with a lower priority can't be overridden by packages from a repository with a higher priority even if the repository with the higher priority has a later version of the package. As the Installing RPMForge webpage states you should "Beware that some packages are newer than the official CentOS version and you should not blindly install those packages. Before you replace a CentOS package you should make sure that will not break anything important. In most cases you can revert any mistakes but it is best to avoid the mess." By usng the yum-priorities plugin, you help avoid that problem.

Next verify that yum-priorities is enabled by ensuring that the following lines are present in /etc/yum/pluginconf.d/priorities.conf :

[main]
enabled = 1

The yum repository information is stored in /etc/yum.repos.d.

cd /etc/yum.repos.d
# ls -l
total 16
-rw-r--r-- 1 root root 2049 Nov 22 20:32 CentOS-Base.repo
-rw-r--r-- 1 root root  622 Nov 22 20:32 CentOS-Media.repo

I added priority=1 as the last line in the following sections of CentOS-Base.repo:

[base]
[updates]
[extras]

I added priority=2 as the last line in the [centosplus] section, which now contains the following lines:

[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus
#baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
priority=2

I installed the rpmforge-release package with rpm -Uhv rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm, which created two new files mirrors-rpmforge and rpmforge.repo in /etc/yum.repos.d. I edited rpmforge.repo and added priority = 11 at the end of the file.

Repositories with lower priority numbers are considered to have a higher priority than than those with higher numbers. E.g. if repository A has priority=4 associated with it while repository B has priority=5 associated with it, repository A has a higher priority than repository B.

I've been seeing memory utilization jumping up to high values a lot lately. Rebooting the system resolves the problem, but I don't want to be rebooting the Exchange server every day. I can also reduce the memory utilization by selecting Run and typing services.msc to bring up the services list, I can then right-click on Microsoft Exchange Information Store and stop the service and then restart it. I then see store.exe using about 20 MB of memory when I check its utilization with the Windows Task Manager

The Microsoft Exchange Information Store service manages the Microsoft Exchange Information Store, which includes mailbox stores and public folder stores. If the service is stopped, mailbox stores and public folder stores on the computer become unavailable, so it needs to be restarted immediately after stopping it.

At [ic] HELP !FreeBSD 5.3 Box With newest version of perl storable problem , I saw the following:

You appear to have a perl configured to use 64 bit integers in its scalar
variables.  If you have existing data written with an earlier version of
Storable which this version of Storable refuses to load with a

   Byte order is not compatible

error, then please read the section "64 bit data in perl 5.6.0 and 5.6.1"
in the Storable documentation for instructions on how to read your data.

(You can find the documentation at the end of Storable.pm in POD format)

That revealed that the problem was linked to the fact that I am now using a 64-bit operating system.

I decided to see if an upgrade Storable module was available.

# cpan upgrade Storable

/usr/lib/perl5/5.8.8/CPAN/Config.pm initialized.


CPAN is the world-wide archive of perl resources. It consists of about
100 sites that all replicate the same contents all around the globe.
Many countries have at least one CPAN site already. The resources
found on CPAN are easily accessible with the CPAN.pm module. If you
want to use CPAN.pm, you have to configure it properly.

If you do not want to enter a dialog now, you can answer 'no' to this
question and I'll try to autoconfigure. (Note: you can revisit this
dialog anytime later by typing 'o conf init' at the cpan prompt.)

Are you ready for manual configuration? [yes]

I entered "no" to the prompt regarding whether I was ready for manual configuration, which resulted in the autoconfigure process proceeding.

I then checked Storable again.

# cpan Storable
CPAN: Storable loaded ok
Going to read /root/.cpan/Metadata
  Database was generated on Sat, 26 Apr 2008 17:29:46 GMT
Storable is up to date.

I checked the version of the module with perlmodver. The version was 2.18.

But the problem still remained. Taking a look at the code in the calendar plugin, I realized it was reading a file, .calendar.cache in the plugins/state directory. I had not noticed the file previously, because I had checked the directory's contents only with ls. I saw it with ls -a. The calendar plugin reads the contents of that file. I had copied the file from the old 32-bit system to the new 64-bit system when I copied the plugins directory and its subdirectores. When I deleted the .calendar.cache file from the state directory and then tried accessing the blog again, the calendar plugin recreated it, but this time it was in the proper 64-bit format that the Storable.pm module was expecting, so I was now able to view the blog with the calendar functionality now working.

Further information on the issue can be found near the end of the Storable.pm file (look in /usr/lib64/perl5/5.8.8/x86_64-linux-thread-multi/Storable.pm).

Perl 5.6.x introduced the ability to optional configure the perl interpreter to use C's C<long long> type to allow scalars to store 64 bit integers on 32 bit systems. However, due to the way the Perl configuration system generated the C configuration files on non-Windows platforms, and the way Storable generates its header, nothing in the Storable file header reflected whether the perl writing was using 32 or 64 bit integers, despite the fact that Storable was storing some data differently in the file. Hence Storable running on perl with 64 bit integers will read the header from a file written by a 32 bit perl, not realise that the data is actually in a subtly incompatible format, and then go horribly wrong (possibly crashing) if it encountered a stored integer. This is a design failure.

Storable has now been changed to write out and read in a file header with information about the size of integers. It's impossible to detect whether an old file being read in was written with 32 or 64 bit integers (they have the same header) so it's impossible to automatically switch to a correct backwards compatibility mode. Hence this Storable defaults to the new, correct behaviour.

What this means is that if you have data written by Storable 1.x running on perl 5.6.0 or 5.6.1 configured with 64 bit integers on Unix or Linux then by default this Storable will refuse to read it, giving the error I<Byte order is not compatible>. If you have such data then you you should set C<$Storable::interwork_56_64bit> to a true value to make this Storable read and write files with the old header. You should also migrate your data, or any older perl you are communicating with, to this current version of Storable.

If you don't have data written with specific configuration of perl described above, then you do not and should not do anything. Don't set the flag - not only will Storable on an identically configured perl refuse to load them, but Storable a differently configured perl will load them believing them to be correct for it, and then may well fail or crash part way through reading them.

I checked the setting of the account from the command line with the reg query command. The account for which I had hidden the account from the welcome screen display was the administrator account in this case.

C:\Documents and Settings\Administrator>reg query "HKLM\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\SpecialAccounts\UserList" /v Administrator

! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\SpecialAccounts\UserList
    Administrator       REG_DWORD       0x0

The value of zero for HKLM\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\SpecialAccounts\UserList\Administrator means the account is not shown on the welcome screen.

I turned the display of that account back on with the reg add command.

C:\Documents and Settings\Administrator>reg add "HKLM\Software\Microsoft\Windows NT\CurrentVersion\WinLogon\SpecialAccounts\UserList" /v Administrator /t REG_DWORD /d 1
Value Administrator exists, overwrite(Y/N)? y

The operation completed successfully

I had to reboot for the administrator account to be displayed with the other accounts on the system at the welcome screen. The picture chosen for the administrator account was then shown with those for the other accounts, allowing one to click on it to logon.

rdesktop-1.5.0-sol10-x86-local.gz Rdesktop is a client for Windows terminal servers - installs in /usr/local. You will also need to install libiconv, openssl-0.9.8f, and to obtain /usr/local/lib/libgcc_s.so.1 you will need to have installed libgcc-3.4.6 or gcc-3.4.6 or higher.

Since one of the requirements for rdesktop 1.5.0 was libiconv , I installed it. I checked the version of gcc on the system. It was 3.4.3.

# /usr/sfw/bin/gcc -v
Reading specs from /usr/sfw/lib/gcc/i386-pc-solaris2.10/3.4.3/specs

Thread model: posix
gcc version 3.4.3 (csl-sol210-3_4-branch+sol_rpath)

Version 3.4.6 was listed as a requirement, but I thought version 3.4.3 would likely suffice.

# /usr/sfw/bin/openssl version

After installing rdesktop 1.5.0, I checked to see if it would run with the exiting 0.9.7d version of OpenSSL, but I received an error message when I attempted to run it.

# /usr/local/bin/rdesktop -0 gna.insursol.com

I decided to download and install the OpenSSL 0.9.8f package from Sunfreeware.com.

# gunzip openssl-0.9.8f-sol10-x86-local.gz
# pkgadd -d ./openssl-0.9.8f-sol10-x86-local

But, when I attempted to run the new version, which is installed in /usr/local/ssl, I received an error message.

# /usr/local/ssl/bin/openssl version
ld.so.1: openssl: fatal: libgcc_s.so.1: open failed: No such file or directory

I checked to see what versions of libgcc_s.so were installed on the system and where they were located.

# find / -name libgcc_s.so\*
/usr/sfw/lib/amd64/libgcc_s.so.1
/usr/sfw/lib/libgcc_s.so
/usr/sfw/lib/libgcc_s.so.1

Since libgcc_s.so was located in /usr/sfw/lib, I then set LD_LIBRARY_PATH to point to that directory. I was then able to successfully run the version of openssl in /usr/local/ssl/bin .

# LD_LIBRARY_PATH=/usr/sfw/lib
# export LD_LIBRARY_PATH
# /usr/local/ssl/bin/openssl version
OpenSSL 0.9.8f 11 Oct 2007

I was then able to use rdesktop on the Solaris 10 system to log into a Windows Small Business Server (SBS) 2003 system as the administrator.

# /usr/local/bin/rdesktop -0 u administrator a.example.com

Note: if you use the above method of setting LD_LIBRARY_PATH and exporting it to run rdesktop, you will need to do so each time you open a new terminal window.

fping (Maintained by Thomas Dzubin)

fping is a ping(1) like program which uses the Internet Control Message Protocol (ICMP) echo request to determine if a host is up. fping is different from ping in that you can specify any number of hosts on the command line, or specify a file containing the lists of hosts to ping. Instead of trying one host until it timeouts or replies, fping will send out a ping packet and move on to the next host in a round-robin fashion. If a host replies, it is noted and removed from the list of hosts to check. If a host does not respond within a certain time limit and/or retry limit it will be considered unreachable.

Unlike ping, fping is meant to be used in scripts and its output is easy to parse.

I downloaded the Intel architecture version of fping for Solaris 10 from Sunfreeware.com and installed it.

# gunzip fping-2.4b2-sol10-intel-local.gz
# pkgadd -d ./fping-2.4b2-sol10-intel-local

Installation of  was successful.

Program usage information is shown below:

# /usr/local/sbin/fping -h

Usage: /usr/local/sbin/fping [options] [targets...]
   -a         show targets that are alive
   -A         show targets by address
   -b n       amount of ping data to send, in bytes (default 56)
   -B f       set exponential backoff factor to f
   -c n       count of pings to send to each target (default 1)
   -C n       same as -c, report results in verbose format
   -e         show elapsed time on return packets
   -f file    read list of targets from a file ( - means stdin) (only if no -g specified)
   -g         generate target list (only if no -f specified)
                (specify the start and end IP in the target list, or supply a IP netmask)
                (ex. /usr/local/sbin/fping -g 192.168.1.0 192.168.1.255 or /usr/local/sbin/fping -g 192.168.1.0/24)
   -i n       interval between sending ping packets (in millisec) (default 25)
   -l         loop sending pings forever
   -m         ping multiple interfaces on target host
   -n         show targets by name (-d is equivalent)
   -p n       interval between ping packets to one target (in millisec)
                (in looping and counting modes, default 1000)
   -q         quiet (don't show per-target/per-ping results)
   -Q n       same as -q, but show summary every n seconds
   -r n       number of retries (default 3)
   -s         print final stats
   -t n       individual target initial timeout (in millisec) (default 500)
   -u         show targets that are unreachable
   -v         show version
   targets    list of targets to check (if no -f specified)

If I wanted to determine what hosts in the 192.168.1.0 to 192.168.1.255 range exist and can be pinged, I could use the command fping -g 192.168.1.0 192.168.1.255.

# /usr/local/sbin/fping -g 192.168.1.0 192.168.1.255
192.168.1.0 is alive [<- 192.168.1.44]
192.168.1.1 is alive
192.168.1.6 is alive
192.168.1.7 is alive
192.168.1.33 is alive
192.168.1.44 is alive
192.168.1.255 is alive [<- 192.168.1.44]
192.168.1.2 is unreachable
192.168.1.3 is unreachable
192.168.1.4 is unreachable
192.168.1.5 is unreachable
192.168.1.8 is unreachable
192.168.1.9 is unreachable
192.168.1.10 is unreachable
<text snipped>
192.168.1.30 is unreachable
192.168.1.31 is unreachable
192.168.1.32 is unreachable
192.168.1.34 is unreachable
192.168.1.35 is unreachable
<text snipped>
192.168.1.40 is unreachable
192.168.1.41 is unreachable
192.168.1.42 is unreachable
192.168.1.43 is unreachable
192.168.1.45 is unreachable
<text snipped>
192.168.1.252 is unreachable
192.168.1.253 is unreachable
192.168.1.254 is unreachable

If I don't want anything displayed for IP addresses where there was no response, I could use fping -a -g <start address> <end address>, as in the example below.

# /usr/local/sbin/fping -a -g 192.168.1.0 192.168.1.255
192.168.1.0 [<- 192.168.1.44]
192.168.1.1
192.168.1.5
192.168.1.7
192.168.1.37
192.168.1.44
192.168.1.255 [<- 192.168.1.44]

The 192.168.1.0 and 192.168.1.255 addresses are network and broadcast addresses respectively, not hosts responding to ping packets. The 192.168.1.44 address is the address of the system from which I ran the ping command.

Searching for other rescue CD's, I also found one from F-Secure, which uses a Knoppix LiveCD to boot a system to perform an antivirus scan of the system. You can use it to boot a Windows system to check the system for viruses without booting into a possibly infected copy of the Windows operating system. F-Secure Rescue CD 2.00 is free and can update itself over the network, if a DHCP server is available on the network to provide it with IP configuration information. You don't need to understand Linux to use the software; you are presented with prompts to walk you through the process of scanning a system.

I double-checked the connector I had put on the cable; it looked fine. I punched down the end at the patch panel again without pulling the cable out of the punchdown block, but the problem remained. I then wondered whether I really needed pins 4 and 5 working for a 10 Mbs or 100 Mbs Ethernet connection. Turns out I didn't. I ran a patch cable from the port on the patch panel to the network switch and plugged the other end of the cable into my laptop; the network connection worked.

The manual for the TVR10/100 LAN Tester provides the following information on the cable pairs required for 10 Mbs and 100 Mbs Ethernet connections.

If a cable problem disables data communications at 100 MB/s.
The problem could be caused by not enough connected pairs: 10Base-T data communications only requires two pair cables. There are two 100Base-T standards, one requires two pair cables and the other requires four wire pair cables. If a two pair cable is used, when four pair cables is required, a slow 10 MB/s connection will be permanently established. The cable problem could be caused by inverted pairs. A pair exists, but the pins are inverted (e.g. 1,2 is 2,1). Or the problem could be the cabling is not rated for 100 MB/s speeds ("category 5" cable).

LAN Type	Cable Pairs Required
10Base-T	1,2	3,6
100Base-T (Type 1 or TX)	1,2	3,6
100Base-T (Type 2 or T4)	1,2	3,6	4,5	7,8

As shown in the above table, 10Base-T or 100Base-T (Type 1 or TX) LAN ports use two pair cables. 100Base-T (Type 2 or T4) LANs require all four pairs. It is best to use and install Category 5 cables with all four pairs to ensure compatibility with all three types of Base-T LANs.

If there is a short or open on pairs 1, 2 and 3,6 all communications will be prevented. If there is a short or open on pairs 4,5 or 7,8 the data rate may drop to 10 MB/s.

A faulty cable with missing or faulty pairs 4,5 or 7,8 may cause the data rate on that cable to drop to 10 MB/s If this faulty cable is between a PC and hub, all data going to and from that single PC will be at a slow rate. If the faulty cable is between two hubs then communications will some times be quick and other times it will be slow. Communications between PC connected to the same hub will be quick. Communications betwen a PC on one hub across a faulty cable to a PC on another hub will be slow. This type of problem can be very difficult to find without a TVR10/100.

So, I should probably fix the problem when I have time, even though the cable provides network connectivity at the moment.

There is a clear explanation of how to build an RJ-45 Ethernet cable at Building a RJ-45 Ethernet cable of a specific length (light version) . A source explaining the difference between 568A and 568B standards is Twisted Pair Connectors. How to wire Ethernet Cables is another good reference for Ethernet cables.

The following memory module was already in the system:

US        BZABW72029   200303

The BIOS memory information was as follows:

I installed the following PNY memory module in the second of the two memory slots in the system.

PNY 512MB
DDR
PC2700
333MHz / 266 MHz
OPTIMA&trade Memory

The following information was on a sticker on the module:

  ASSY. IN TAIWAN

The package had "MD0512SD1-333-BB" on it above the UPC. The UPC was 7 51492 34983 1.

When I booted into Windows and ran winver, it showed "Physical memory available to Windows: 784,176KB".

I ran a 30 minute test of the memory with Windows Memory Diagnostic Beta. No errors were found in the 3 passes of the diagnostic program that were run.

[/hardware/pc/memory] permanent link

I also needed to install a sound card, since the on-board audio stopped working. I changed the BIOS settings for the on-board audio support from "enabled" to "disabled". The option is listed under Advanced then Peripheral Configuration in the BIOS Setup Utility.

I checked the Crucial Memory site for information on the memory that the system will support.

The Crucial Memory site providded the following information at Computer memory upgrades for Gateway E-2300 Series (4 DIMM Slots)

Although the memory can be installed one module at a time, the best performance comes from using matched pairs of modules.

Each memory slot can hold DDR PC3200, DDR PC2700 with a maximum of 1 GB per slot.^*

*Not to exceed manufacturer supported memory.

The Crucial Memory site also had the following series of questions and answers regarding memory for the system:

Q: Will my system recognize the maximum upgrade?

A: Possibly

How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at http://www.crucial.com/kb/answer.aspx?qid=4251.

Q: What memory goes into my computer, and will a faster speed be backward-compatible?

A: DDR memory with support for DDR PC3200,DDR PC2700 speeds.

Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds. [DDR PC3200 and DDR PC2700 modules were listed below the statement]

Q: How much memory can my computer handle?

A: 4096MB

Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future.

Q: Do I have to install matching pairs?

A: Yes

Your system requires that you install memory in pairs.

The system had a 256 MB memory module in Channel A DIMM0. That module had the following information on a sticker on it.:

I put the following memory in the system:

Kingston Technology
Value RAM
KVR333/1GR

The module had a sticker on it with the following information:

The Crucial Memory site indicated that memory must be installed in matching pairs, but I wasn't sure if that applied just to modules inserted in the same channel, i.e., I wasn't sure if I could install the 1 GB module in Channel B, since the 256 MB module was in channel A. I put the new module in Channel B DIMM0. When I powered on the system, I saw "1264MB System RAM" but then received the error message "Dual-channel operation requires identical paired DIMMs installed across both memory channels." I then tried the new 1 GB module in Channel A DIMM1. Again I saw "1264MB System RAM" and the same error message, so I removed the 256 MB module and moved the 1 GB module to Channel A DIMM0. This time when I powered on the system I saw "1008 System RAM" followed by "Keyboard Error" and then "Memory Size Decrease". I powered the system off and on and didn't see the keyboard or "memory size decrease" messages again, though the system did display "1008 System RAM" again.

When I checked the BIOS configuration, I saw the following:

When I selected the Advancecd tab in the BIOS Setup Utility and then chose Video Configuration, I saw the following:

Presumably, the remaining 16 MB of the 1024 MB module is being allocated to the frame buffer, which is why the system is reporting 1,008 MB during the Power-on Self-test (POST) process.

When I booted into Windows and ran winver, I saw "Physical memory available to Windows: 1,030,896 KB".

I had also installed a Dynex model DX-SC51 sound card in PCI slot 1 at the same time I installed the memory. When I checked on the sound card, Windows Media Player reported "Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly."

Under the Device Manager, I saw "Unknown device" listed under display adapters, but no new audio device listed. When I tried to install the Dynex driver, I saw the warning message "Undetermine Card! Please do not click cancel on device manager!" Clicking on OK there produced another warning message "OS not support!"

I opened the case and checked the sound card. I found it wasn't seated fully in its slot. I reseated the card. When I rebooted and logged in as the adminsitrator, the Found New Hardware Wizard appeared. I inserted the CD that came with the sound card. The wizard indicated it found a Multimedia Audio Controller, an Envy24 Family Audio Controller WDM. After the sotware was installed, I was able to play music files on the system and hear sound from the speakers.

I ran a memory test on the new memory module with Windows Memory Diagnostic Beta. I let the test run for an hour and 30 minutes. The diagnostic program completed 22 passes with no errors found.

I sometimes encounter a problem where I can't see the taskbar at the bottom of the Windows display or the bottom of windows displayed on the remote Windows system due to differences in the resolution for the screen on the Linux/Unix system and the resolution of the Windows system. The problem can be resolved by specifying the -f option when starting rdesktop, so that you get a full screen display., e.g. rdesktop -0 -f -u jsmith 192.168.0.44. But what do you do when you wish to put the remote session in a window rather than have it occupy the full screen without disconnecting? You can hit the Ctrl-Alt-Enter keys simultaneously to switch to a windowed view. You can also use Ctrl-Alt-Enter to switch to a full-screen view, if you didn't start redesktop with the -f option.

When I checked the Ghost services (click on Start, select Run, type services.msc and hit Enter), I found the Symantec Ghost COnfiguration Server was started, but not the Symantec Ghost Database Service, which had a manual startup type. I double-clicked on Symantec Ghost Database Service and clicked on the Start button to start it. I received the error message below:

Services
	Could not start the Symantec Ghost Database Service service on Local Computer. Error 2: The system cannot find the file specified. OK

The "path to executable" value was C:\Program Files\Symantec\Ghost\bin\dbserv.exe. When I checked, I found there was no C:\Program Files\Symantec\Ghost directory. I believe it wasn't recovered when a disk drive problem occurred previously. To correct the problem, I reinstalled Symantec Ghost. I chose the Repair option during the installation. At the end of the repair operation, I saw the error message below:

Symantec Ghost Configuration Server
	08001 [Sybase][ODBC Driver][Adaptive Server Anywhere]Unable to connect to database server: Database server not running Error 2: The system cannot find the file specified. OK

So I tried the Remove option to "Remove Symantec Ghost Corporate Edition from your computer". After deinstalling the software, I reinstalled it. The Symantec Ghost Console then started without a problem. And when I checked the running services, I saw that both Symantec Ghost Configuration Server and Symantec Ghost Database Service were started.

I didn't see the client systems in the default machine group, so thought I had to add the client systems back into the console. When I tried to reinstall the client software on a system, the installation failed. When I checked the RemoteInstall.log, I saw the reason listed as "Remotely Installed Client is installed on this machine."

To resolve the problem I restored the privkey.crt, pubkey.crt, and C:\Program Files\Symantec\Ghost directory from a Ghost backup I had from some time ago.

To backup those files and that directory or restore over them, you should close the Ghost Console, if you have it open, and stop the running Ghost services. You can stop the Ghost services by clicking on Start, then selecting Run and typing the following command and hitting Enter. You need to include the double quotes where shown below.

"c:\program files\symantec\ghost\ngserver.exe" -stop

If you check the running services, you should then see both Symantec Ghost Configuration Server and Symantec Ghost Database Service are stopped.

I then restored the privkey.crt, pubkey.crt, and C:\Program Files\Symantec\Ghost directory from the backup. Afterwards, I ran the command "c:\program files\symantec\ghost\ngserver.exe" -start to restart the Symantec Ghost services. I then saw the systems in the default machine group I had been using previously for the Ghost backups.

Bopup Scanner will perform a NetBIOS scan of a network, which will show Windows systems on the network. The program first tries to ping an address it is scanning. So, if you were watching its scan with a sniffer, you would see an ARP request for the IP address. If there is a reply to the ARP request, an ICMP echo request is sent to the IP address. If an echo reply is received, Bopup Scanner will then check for a response from the scanned IP address on UDP port 137. Port 137 is associated with the NetBIOS Name Service commonly used on systems running the Microsoft Windows operating system. The NetBIOS Name Service is typically how Windows computers find out information concerning the networking features offered by a computer, such as system name, file shares, etc.

Because it is only scanning for responses to NetBIOS Name Service requests, Bopup Scanner will show a red circle for IP addresses where it received no response to a NetBIOS Name Service query, even though there may be a system at that address. E.g. there may be a Linux system, networked copier, router, etc. at the address.

Regarding installation of the software, there is no installation procedure for the program. You simply run scanner.exe. When you first run it, it will create the following registry entries:

Keys added: 5
-------------
	HKEY_CURRENT_USER\Software\B Labs
	HKEY_CURRENT_USER\Software\B Labs\Bopup Scanner
	HKEY_CURRENT_USER\Software\Bopup Scanner
	HKEY_CURRENT_USER\Software\Bopup Scanner\Scanner
	HKEY_CURRENT_USER\Software\Bopup Scanner\Scanner\Settings

After starting the program, click on the Refresh button with the green arrows next to it on the toolbar menu to begin a scan of the subnet the system is on.

If you wish to check on whether a webserver is running on any of the scanned IP addresses, click on Options and check "Scan for HTTP servers (80, 8080 ports)".

You can save the results to a text file by clicking on Actions and selecting Save list.

The developer, B-Labs Software, also offers other software that can be used for secure instant messaging.

So, I decided to look for an add-on that might add similar functionality for Internet Explorer. I found a free add-on, IE7Pro, that offers that functionality as well as other enhancements for Internet Explorer. The developer states "IE7Pro includes Tabbed Browsing Management, AD Blocker, Flash Block, Super Drag Drop, Crash Recovery, Proxy Switcher, Mouse Gesture, Tab History Browser, Inline Search, User Agent Switcher, Webpage Capturer, Greasemonkey like User Scripts platform, User Plug-ins and many more power packed features. You can customize not just internet Explorer, but even your favorite web site according to your need and taste using IE7Pro."

During the installation, which uses a Nullsoft Install System v2.33 installation program, you are given the option to select default settings, which are shown below:

Please select default settings:

[x] Enable ADblock
[ ] Enable Userscripts
[ ] Enable Plugins
[X] Enable Spelling Checker
[ ] Set EasyHome as Homepage

At the end of the installation, you are requested to set the default search engine to be IEPro's Google based search, to help finance further development of the software, but you don't have to do so. Selecting that option is certainly a small measure that you can take to make continued development of the software possible.

To simulate a system crash, I powered off the system. When I restarted the system and opened Internet Explorer, I saw a "Crash Recovery" window stating "Your last session crashed, Please review and open last URLs. All of the Internet Explorer 7 tabs I had open previously were listed and checked to be reopened. I could deselect tabs I didn't want reopened, if I wished. There were also Select All and Select None buttons. I chose to reopen all of the tabs I had open previously. Unfortunately, unlike Opera's crash recovery feature, I couldn't click on the backwards arrow button in Internet Explorer to view my history of previously visited sites in any tab. So, IE7Pro definitely offered an improvement over the total lack of crash recovery features in Internet Explorer, but also falls far short of the built-in crash recovery features of Opera.

E.g., suppose you have the following information in a spreadsheet

The function counta(A1:A5) would count those cells that aren't empty in cells A1 to A5 yielding 3. The function countif(B1:B5,"*") would also count those cells that contain text in cells B1 to B5, yielding 4 as well.

Note: counta will count cells that have formulas in them even though those formulas may amount to nothing appearing in the cell, i.e. they evaluate to "".

If you wanted to count the number of cells that contained specific text, e.g. birch, you could use countif(B1:B5,"birch"), which would yield 2. The count is case insensitive, i.e., if one of the cells contained "BIRCH", instead of "birch", the count would still be equal to two.

If you wanted to count the number of cells that contained "birch" in column B and "plum" in column A, then countif won't work, since you can only specify one criteria with it. You could use sum instead. E.g. sum((B1:B5="birch")*(A1:A5="plum")), which yields 1. The * in this case "ands" the two conditions. Note: You have to hit the Ctrl, Shift, and Enter keys simultaneously when you've typed the formula in order to enter it. If you don't, you will see a #value appear in the cell. This type of formula is considered to be an "array" formula or CSE formula, since it requires the Ctrl-Shift-Enter keys to be hit to enter it. When it is entered, you will see {} appear around the formula.

I received the same message if I tried viewing any log.

Symantec has a knowledgebase article on the problem at Error: "Symantec AntiVirus could not collect all the log data from the selected computer(s) . . ." when viewing client logs in Symantec System Center . I followed the steps listed in that article.

I could ping the IP address of the system and ping -a 192.168.0.7 showed the hostname associated with the address. I could also ping the server from the client system using ping and ping -a, which confirmed network connectivity and the ability to do reverse lookups on the IP addresses to get host names.

I checked for the presence of any .cer server group root certificate on the server and the client. I didn't see any .cer file on either system, but nor did I see a certificate on a client for which I could successfully check log files from the antivirus server, so I didn't think that was the source of the problem.

I could successfully start the Symantec AntiVirus Client program on the client system. It showed the correct server name. Though nothing was listed for "group", nothing was listed for "group" on a system I could successfully query from the server, either.

And from the server, I could query the client and see that the Symantec rtvscan.exe program was running.

C:\>tasklist /s 192.168.0.7 /fi "imagename eq rtvscan.exe"

Image Name                     PID Session Name        Session#    Mem Usage
========================= ======== ================ =========== ============
Rtvscan.exe                   1760                            0     46,604 K

When I checked the Windows XP firewall settings on a system I could successfully query from the antivirus server, I saw a firewall rule listed for User Datagram Protocol (UDP) port 2967, which the Symantec RTVScan program uses. I checked the firewall rules on the system I couldn't successfully query with the command netsh firewall show portopening. I did not see a rule for RTVScan, so I created one from the command line using the command netsh firewall set portopening protocol = UDP port = 2967 name = "Symantec AntiVirus Client Management" mode = ENABLE scope = CUSTOM 192.168.0.33 (IP address 192.168.0.33 corresponds to the IP address of the antivirus server).

When I tried checking the antivirus log files from the server again, I still could not do so. Looking at the firewall rules on the client with netsh firewall show portopening verbose = enable (you have to specify the verbose option to see the scope of rules), I saw that I had mistyped the IP address of the server when I created the RTVScan rule with the netsh command. So I re-entered the netsh firewall set portopening protocol = UDP port = 2967 name = "Symantec AntiVirus Client Management" mode = ENABLE scope = CUSTOM 192.168.0.33 command exactly as before with the exception that this time I specified the IP address correctly.

I was then able to check the virus history and other logs on the client from the Symantec System Center.

You can check on whether an IP address has been associated with attacks on other systems at DShield or myNetWatchman by performing an IP lookup.

You can also obtain information on the "reputation" for a site at Barracuda Central by performing a lookup on either an IP address or a domain name. Barracuda Networks sells widely used spam firewall devices, so a poor reputation listing at Barracuda Central may lead to email from an IP address listed there, or with a domain name in the body of email messages being found there, being blocked by those using Barracuda Networks security devices.

Another reputation site is TrustedSource. You can lookup an IP address there and see a graph of activity associated with that site. If you see red bars on the graph, those represent malicious activity associated with the IP address on the days for which those bars appear.

Or perhaps you own example.com. The cybersquatter may purchase example.net, if it is available. Someone seeing example.net in an email may think the domain belongs to your company and visit a site that might have nothing but ads, perhaps even risque ones, or the site might try to infect visitors with adware/spyware, which might harm your company's reputation, even though you don't own the domain name and have no control over the site.

CitizenHawk helps you locate potential cybersquatter sites for your domain name.

I.e., if you can use telnet 127.0.0.1 25 and see the sendmail banner, but when you use telnet 192.168.0.44 25 (presuming 192.168.0.44 is the IP address for the mail server), you get "connection refused" messages, then the default configuration option in sendmail.mc is likely preventing the connection by causing sendmail to only listen on the loopback address.

# telnet 192.168.0.44 25
Trying 192.168.0.44...
telnet: connect to address 192.168.0.44: Connection refused
telnet: Unable to connect to remote host: Connection refused

To resolve the problem, look for the following lines in sendmail.mc , which on a Linux system will likely be in the /etc/mail directory.

dnl #
dnl # The following causes sendmail to only listen on the IPv4 loopback address
dnl # 127.0.0.1 and not on any other network devices. Remove the loopback
dnl # address restriction to accept email from the internet or intranet.
dnl #
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Edit the sendmail.mc file from the root account. Put a dnl # at the beginning of the DAEMON_OPTIONS line to comment out the line.

dnl # DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Then issue the following commands:

m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
/etc/init.d/sendmail restart

The first command rebuilds the .cf configuration file from the modified .mc file. The second restarts sendmail so that it is using the new configuration file.

Since the communications occurred at 18:30 when the employees using those systems would have gone home, I did a Google search on the FQDN, 216-115-223-200.expertcity.com, which was associated with that address. A McAfee SiteAdvisor webpage linked the site with GoToMeeting, i.e. legitimate software on the users' systems. That webpage stated "When we installed and ran GoToMeeting 2.0.0.127 (gotomeeting.exe), the following network servers were contacted." It then listed the following addresses:

Configure optional SNMP parameters from here.

You can put in whatever name you would like to use for the router in the System Name field, e.g. Netopia Router and then hit Enter to advance to the next field, where you can specify the location, e.g. 1020 Maple Street. Hit Enter to fill in the System Contact field. The default read-only community string is public. To prevent others from accessing information from the router, you can provide another community string. You can provide a read/write community string as well, if you like. If you want authentication traps sent to another device, enable authentication traps and specify IP trap receivers. Otherwise, you can leave these as is.

You can return to the main menu, if you wish, by hitting the Escape key until to back up through the menus.

If you want a free program to monitor the router via SNMP from a Windows system, try PRTG Traffic Grapher. It is fairly straight-forward to set up and can even install its own webserver on the system on which you install it. If you already have webserver software running on the system on which you install it using port 80, PRTG will automatically set up its own webserver at port 8080. Or you can choose a different port, if you prefer. You can specify userids and passwords granted access to the webserver, where the PRTG graphs are displayed.

I blocked the 221.130.187.49 system with route add 221.130.187.49 reject . I then checked DShield to learn if it has been observed attacking other systems. The DShield report for 221.130.187.49 showed it was first reported engaged in hostile activity on 2008-02-11 and the last reported incident was today 2008-02-13. The IP address is a Chinese address. When I checked the IP Details for the ports the system was attacking, I found it was listed only for port 21 attacks, i.e. FTP attacks.

It was also listed at myNetWatchman. The Incident Detail report for that IP address at myNetWatchman showed the system had been attacking other systems on port 21 and port 22 (SSH) as well from February 5, 2008 onwards.

I then checked the second system attacking, which was 202.57.128.159.sta.isp-thailand.com. The IP address for it is 202.57.128.159. Note: a reverse lookup on 202.57.128.159 yields a Fully Qualified Domain Name (FQDN) of 202.57.128.159.sta.isp-thailand.com, but a forward lookup on 202.57.128.159.sta.isp-thailand.com does not yield an IP address.

I ran an nmap scan of it to see what operating system it was running. I got the following results:

# nmap -P0 -O 202.57.128.159

Visting http://202.57.128.159/ with a browser showed "Welcome to web4.thaibestserver.net".

When I checked DShield for any reports on hostile activity for that IP address, which is a Thai address, I found it was first reported engaged in hostile activity on 2008-02-08 with the most recent report dated 2008-02-09 (see IP Info (202.57.128.159)). The IP Details 202.57.128.159 report showed all of the incidents to be FTP attacks.

There was also an Incident Detail report for it at myNetWatchman, which also showed the system engaged in FTP attacks from February 6 onwards.

I blocked it with route add 202.57.128.159 reject. I also turned off the FTP service on the system, since it isn't needed at the moment.

When I checked the PDF files produced by PrimoPDF, I found they were always zero bytes in size. When the files were being produced I would hear an error beep.

An Error after converting posting at the PrimoPDF Forums, suggested giving the Users group on the system full control of the directory into which PrimoPDF is installed.

From the Windows Explorer, I right-clicked on the directory under Program Files into which I had installed PrimoPDF and chose Properties. I saw that the Users group had only read access, i.e. only the read & execute, list folder contents, and read permissions were granted to the Users group for that folder.

Note: you can use the cacls command to check permission from the command line, e.g. cacls "\program files\primopdf", if the installation directory was \program files\primopdf. You will see BUILTIN\Users:(OI)(CI)R. The R at the end indicates that the Users group on the system, to which all normal user accounts belong, has only read access to that directory.

If you are logged into an account that is a member of the Administrators group on the system, you can right-click on the directory and choose Properties to reset the security permissions. Click on the Security tab, then select the Users group under "group or user names", then grant Full Control.

Since I was logged into a normal user account at the time I encountered the problem and had a lot of windows open and didn't want to have to close all of them, logoff, logon as an administrator, logoff, logon to my user account again, and then reopen all of the applications and files I previously had open, I used the cacls command to reset the permissions. To use that method, you need to take the following steps, if you are currently logged into an unprivileged user account.

1. Open a command prompt window as the Administrator. On Windows XP systems, you can do so by going to C:\WINDOWS\system32\ and right-clicking on cmd.exe while holding down the shift key (if you don't hold down the shift key at the same time, you won't see the "run as" option). Then select Run as. Click on The following user and put in Administrator, or some other account with administrator access, for the user name, and enter the appropriate password. Then hit Enter or click on OK. A command prompt window will open with Administrator credentials.
2. Enter the command cacls "\program files\primopdf" /E /G Users:F to give all users of the system full control of the directory where you installed PrimoPDF, presuming that you installed it in \program files\primopdf. Granting full control of the directory means they can add or delete files in that directory. The Users group will still only have "read" access to the dll and exe files in the directory, though. The /E means "edit the existing Access Control List (ACL) rather than creating a new one and the /G grants access for the account or accounts specified as a parameter. The F at the end grants "full" access. You can enter cacls /? for help with the cacls command. You will see something like "processed dir: C:\program files\PrimoPDF", if the command is successfully executed.

Smart Network Data Services (SNDS) is a revolutionary Windows Live Mail initiative designed to allow everyone who owns IP space to contribute to the fight against spam, malware, viruses, and other internet evils, and to protect e-mail and the internet as a valued communications, productivity and commerce tool. Windows Live Mail and MSN Hotmail, with over 250 million active user accounts world-wide, is in a unique position to collect and analyze e-mail activity data. By providing that data to service providers, most of whom wouldn.t otherwise have access to any such data, they are empowered to use their relationship with their customers to react and take repair actions, such as preventing spam from originating within their IP space. The overarching goal of SNDS is to make the Internet a better, safer place. Working together, Windows Live Mail and service providers can make their respective customers happier and more satisfied with the various services we all provide.

When you click on Submit you will see the message "We've determined that the following email addresses are associated with the specified network in an appropriately authoritative way. Please choose one that you can receive mail at and we will send instructions for completing the signup process to that address." You may then see 4 addresses similar to those below:

abuse@yourdomain.com 
noc@isp1.net 
noc@isp2.net 
postmaster@yourdomain.com

Two of the addresses will be of the form abuse@yourdomain.com and postmaser@yourdomain.com, assuming that a reverse DNS lookup on a provided IP address yields "yourdomain.com".

A "whois" lookup will also be done on a provided IP address using the relevant registrar, which, if you are in the U.S. will likely be the American Registry for Internet Numbers (ARIN). The "OrgTechEmail" address listed for the IP address may be used as one of the possible addresses, e.g. noc@isp1.net, if that was the "OrgTechEmail" listed for the ISP.

You can see further information on how the email addresses are derived at SNDS - FAQ.

If you have PTR record in DNS that points back to yourdomain.com, and wish to use one of those email addresses, make sure that you have valid abuse@yourdomain.com and postmaster@yourdomain.com email addresses.

What data does SNDS provide?

The data provided by SNDS is meant to provide as broad a picture of an IP's mail sending behavior as necessary for the system's consumers to be able to stop spam.  It reports on a variety of characteristics of mail traffic.  The data points provided are designed to be difficult or impossible for spammers to avoid differentiating themselves from well-behaved mailers.  Similarly however, data isn't provided on IPs that send very little mail because they (currently) account for a negligible amount of spam.  For each IP within the ranges that the user has been authorized, the following data is provided:

• IP Address
• Mail data
  • Activity period
  • Traffic data
    • SMTP verb and message recipient counts
    • Sample commands
  • Junk mail data
    • Filter result
    • Complaint reports
    • Trap hits
    • Sample messages
• Virus-infected emails
• Malware hosting
• Open proxy status

An email message is sent to the address you specified. You will need to go to a link provided in that email message to grant access to the data to a Windows Live ID account, such as a hotmail.com email address, you specified when you requested an account.

Once you have confirmed access, you can view data at SNDS - View Data There you will see a calendar where you can select dates for which to view data. You have the option to change your settings to allow access your data as a .CSV file without the need for browser-based authentication technologies such as Windows Live™ ID. This facilitates access to your data via your own automated scripts or programs.

I didn't see any data listed for an IP address I specified. I know email is sent from that address to hotmail.com users, but the volume of traffic is fairly low. The SNDS - FAQ states that "data isn't provided on IPs that send very little mail because they (currently) account for a negligible amount of spam."

I requested a delisting from their Unsubscribe Blacklist Support page. When I looked up the address at LASHBACK, I found it was listed. When I requested it be delisted at 12:30 PM, I was notified that it would be removed within 1 hour. When I had checked for the address on the MxToolBox Email Blacklist Check page, I had seen a TTL value of 3594, which is 59.9 minutes, listed for it for the LASHBACK list.

The following steps can be taken to see if the system is recognizing the presence of the printer dock.

1. Click on Start.
2. Select All Programs.
3. Select Kodak.
4. Select Kodak EasyShare printer dock.
5. Select Kodak printer dock firmware updater. When the application opens, you should see the printer name listed along with the current firmware version number as shown below.

   

In this case nothing was listed under "Printer Name" nor under "Firmware Version Number". I unplugged the USB cable from the computer and plugged it back in. I then saw the message below:

USB Device Not Recognized

One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.

I tried plugging the device into two other USB ports with the same results. I unplugged the cable from the printer dock and powered it off. I plugged the cable back in and powered it on. I then heard noises from the unit and when I exited the Kodak printer dock firmware updater program and restarted it, I saw entries listed under "Printer Name" and "Firmware Version Number"

2. Select Dynamic Addresses from the Address Manager menu.

                                  PowerConnect 3024
                                   Address Manager

   <ESC> Back                                      <Ctrl-L> Refresh  <Ctrl-W> Save

You will then see the MAC addresses that have been seen by the switch for each port. Ports with no device attached will not be listed. If nothing is listed for a port at the time you check, though, that does not necessarily mean that no device is attached to that port, only that no activity has been seen on that port recently. A system could be attached to the port, but turned off, or may be on, but has not communicated with another device over the network recently.

If the switch is seeing multiple MAC addresses on a port, as it would if there is another switch or hub plugged into the port, which itself has multiple systems plugged into it, it will show all of the MAC addresses. In the example below, 5 addreses are listed for port 6 and 4 addresses are listed for port 16. There is another switch connected to port 6 and a hub connected to port 16.

                               PowerConnect 3024

If you see a MAC address which you don't recognize, you can lookup up the manufacturer of the network adapter associated with that address at Vendor/Ethernet MAC Address Lookup and Search, which may help you identify what type of device is connected on the port showing that MAC address. For instance, when I look up 00:09:6b:19:38:a5, I see the vendor listed as "IBM Corporation". When I look up 00:17:a4:26:88:d5, I see "Global Data Services (may now be Hewlett-Packard, HP)" listed and, in this case, the device is an HP K5400 printer.

E.g. the command netsh interface ip set address name="Local Area Connection" static 192.168.0.66 255.255.255.0 192.168.0.1 1 could be used to set the IP address to a static value of 192.168.0.66 with a subnet mask of 255.255.255.0 and a default gateway of 192.168.0.1.

1. Click on Start.
2. Select All Programs.
3. Select Microsoft Exchange.
4. Select System Manager. Note: the System Manager is applicable if you have Exchange Server 2000 and later. For Exchange Server 5.5 and earlier, you will need to run Exchange Administrator.
5. Click Servers. You will then see the version displayed. For Exchange Server 2000, the version is 6.0; for Exchange Server 2003, the version is 6.5.

You can also determine the version number, by going to C:\Program Files\Exchsrver\bin, right-clicking on store.exe, selecting Properties, and clicking on the Version tab.

Clicking on Product version will show the version of the Exchange software. In the case shown above, the file version is listed as 6.5.7651.61 while the product version is 6.5. The digits after the 6.5 in the file version don't necessarily match the build version displayed using the first method.

Note: the version number you see using the above methods may not necessarily be the same version number you would see displayed if you telnet to port 25 on the Exchange server. E.g. the above method of determining the version of Exchange running on a system shows it to be 6.5 (Build 7638.2: Service Pack 2), but if I telnet to port 25 on that same Exchange server, I see the following:

220 example.com Microsoft ESMTP MAIL Service, Version: 6.0.3790.3959 ready at
Wed, 13 Feb 2008 19:07:30 -0500

I.e. the "ESMTP MAIL Service" version is not the same as the version number for the Exchange server software on the system, so you can't infer that the version number you see displayed when you connect to port 25 on the system is the Exchange server version number.

Then another HPProductAssistant window would appear stating "The feature you are trying to use is on a CD-ROM or other removalable disk that is not available" and asking me to "Insert the 'HPProductAssistant' disk and click OK" with "1" appearing in the "use source" field. When I clicked on the browse button, I saw it was looking for hpproductassistant.msi.

If I clicked on the Cancel button, I would see the error message below:

If I clicked on OK, which was the only option, the process would just repeat. Clicking on the Cancel button at the point where it prompted for the HPProductAssistant installation file, just kept the process repeating as well. I had to kill the application through the Task Manager to stop it.

When I checked on what process was associated with the HPProductAssistant in the Task Manager by right-clicking on HPProductAssistant under the Applications tab in the Task Manager and selecting Go To Process , I found it was hpqtra08.exe That file is associated with "HP Digital Imaging Monitor" software and is located in C:\Program Files\HP\Digital Imaging\bin\hpqtra08.exe

When I went to Start, All Programs, and Startup, I found "HP Digital Imaging Monitor" listed there. It was probably put there during the installation of software for the user's printer. HP will install a lot of other software in addition to a printer driver when you use the HP-provided installation disc for one of their printers. Since it wasn't working and I doubted the user had any need for it, I clicked on Start, All Programs and Startup then right-clicked on "HP Digital Imaging Monitor and selected Delete to get rid of the entry from the startup group. I rebooted the system to verify that the problem would no longer occur; it did not.

But sometimes I run into difficulty with multi-page news articles. I don't want to have to furl each page individually. Some websites offer a "print" function, so that you can display a copy of all pages of the article at once to send them to the printer at once. But often, when the window opens that displays the entire article for printing, I don't see the Internet Explorer (IE) menubar with "File, Edit, View, Favorites, Tooks, and Help" on it. The link to furl pages is under "Favorites", so I don't then have access to that link.

One alternative is to right-click on the "print" version of the webpage, choose "Properties" and then copy the URL for the webpage, which you can paste into another IE window with the menubard displayed to access the page. Another method is to hit the Ctrl and "I" keys simultaneously, which will bring up the IE Favorites box.

Other IE shortcut keys to view and explore web pages are listed below:

usage:
pkginfo [-q] [-pi] [-x|l] [options] [pkg ...]
pkginfo -d device [-q] [-x|l] [options] [pkg ...]
where
  -q #quiet mode
  -p #select partially installed packages
  -i #select completely installed packages
  -x #extracted listing
  -l #long listing

and options may include:
  -c category, [category...]
  -a architecture
  -v version

If you just issue the command pkginfo, you will see list of all of the installed packages on the system with a one-line listing per package.

If you are just interested in a particular package, you can use pkginfo pkgname where pkgname is the relevant package. But you need to bear in mind that the name assigned to the package may have SUNW in front of it or may not otherwise be exactly what you expect. E.g., suppose I want to know whether the zlib package is installed, because I want to install some other package that lists the zlib software as a dependency. If I use the command pkginfo zlib, I see the following:

# pkginfo zlib
ERROR: information for "zlib" was not found

Using pkginfo | grep -i pkgname will likely be better, unless you are certain of the package name.

# pkginfo | grep -i zlib
system      SUNWzlib                         The Zip compression library

Now I see the package name for the zlib package is SUNWzlib and I could use that command with the pkginfo command, but I want see any more information unless I use the -l option to get a long listing.

# pkginfo SUNWzlib
system      SUNWzlib The Zip compression library
# pkginfo -l SUNWzlib
   PKGINST:  SUNWzlib
      NAME:  The Zip compression library

The long listing shows me the version of zlib installed, which in this case is version 11.10.0. I also see the installation date was July 8, 2006 at 11:00 P.M.

1. Solaris: list installed packages with pkginfo

When a browser retrieves a webpage, it sends a set of values to the webserver. Those values, which are called "headers", include a "user-agent" header that identifies the browser to the server. E.g. a particular version of Internet Explorer may identify itself as "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)".

Some websites may use the user-agent header for statistical purposes, e.g. to determine which browsers are most commonly used to access the website. Such information may help a web developer tailor the site to the ones most commonly used to view the site. Or the the website developer can use the information to tailor its output to the browser being used by a particular user. E.g., if a browser doesn't support a particular feature used in the code on the website, the website software can present the viewer with an alternative webpage.

Wget identifies itself as "wget x.y.z", where x.y.z is the version of wget in use, e.g. "wget 1.8.2". So, if you retrieve a webpage with wget, the webserver might see User-Agent: Wget/1.8.2" as one of the headers submitted to it by the browser.

In this case the website, where the page resided I wanted to access, was seeing User-Agent: Wget/1.8.2" and denying access to the page. Fortunately, you can use the --user-agent argument for wget to specify that wget announce itself to a webserver as any browser you might wish to emulate.

-U agent-string
       --user-agent=agent-string
           Identify as agent-string to the HTTP server.

           The HTTP protocol allows the clients to identify themselves using a
           "User-Agent" header field.  This enables distinguishing the WWW
           software, usually for statistical purposes or for tracing of proto-
           col violations.  Wget normally identifies as Wget/version, version
           being the current version number of Wget.

           However, some sites have been known to impose the policy of tailor-
           ing the output according to the "User-Agent"-supplied information.
           While conceptually this is not such a bad idea, it has been abused
           by servers denying information to clients other than "Mozilla" or
           Microsoft "Internet Explorer".  This option allows you to change
           the "User-Agent" line issued by Wget.  Use of this option is dis-
           couraged, unless you really know what you are doing.

I had wget pretend to be Internet Explorer by using the command below:

wget --user-agent="Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)" --quiet --output-document=$outfile $url

After editing my script to use the --user-agent option, the script was able to download the webpage as before, placing the output in the file designated by the $outfile variable in the script and using the URL I specified as an argument to the script.

Server built:   Jun 26 2002 01:03:14

Version 2.0.59 is the current version listed at Sunfreeware.com - SPARC/Solaris 7 Packages.

The dependencies statement for Apache 2.0.59 listed libiconv as a dependency and stated "you may need /usr/local/lib/libgcc_s.so.1 either from the libgcc-3.3 or gcc-3.3.2 or higher packages." When I checked the version of gcc with gcc -v, I saw it was 3.0.4. So I first upgraded libiconv.

I installed libiconv 1.11 on a Sun SPARC Solaris 7 system. I obtained the package from Sunfreeware.com - SPARC/Solaris 7 Packages.

# gunzip libiconv-1.11-sol7-sparc-local.gz
# pkgadd -d libiconv-1.11-sol7-sparc-local

Since libintl was listed as a dependency for libiconv, I tried to determine if libintl on the system was the latest version. I looked for libiintl files on the system. I found several.

# find / -name libintl\* -print

When I looked in /usr/include/libintl.h, I saw it was version 1.12, so I upgraded libintl to the 3.4.0 version from Sunfreeware.com - SPARC/Solaris 7 Packages.

When I tried to restart Apache to run the new version, I received the message below:

# ../bin/apachectl restart
Syntax error on line 344 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'Order', perhaps mis-spelled or defined by a module not included in the server configuration

When I checked what was at line 344, I found Order allow,deny.

<Directory "/usr/local/apache2/htdocs">
<text snipped>
#
# Controls who can get stuff from this server.
#
    Order allow,deny
    Allow from all

</Directory>

I commented out the "order" and "allow" lines to see what would happen. I then received an error message concerning the UserDir command in httpd.conf.

I checked the compiled-in modules for Apache with httpd -l and saw the following:

# ../bin/httpd -l
Compiled in modules:
  core.c
  prefork.c
  http_core.c
  mod_so.c

The order command requires the mod_access module to be loaded in Apache. It was apparently compiled into the previous version I had running on the system, but it isn't compiled into the current version, so I added LoadModule access_module /usr/local/apache2/modules/mod_access.so to /usr/local/apache2/conf/httpd.conf.

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
LoadModule access_module /usr/local/apache2/modules/mod_access.so

Note: the location of mod_access.so and other modules may be in a different location on other systems, e.g. under Linux it may be at /etc/httpd/modules/mod_access.so. I also discovered later that I should have put LoadModule auth_module /usr/local/apache2/modules/mod_auth.so in as well to address this error as shown at Adding Modules to httpd.conf With Apache 2.

When I added the mod_access.so line and ran apachectl restart, I then received the error message below:

# ../bin/apachectl restart
Syntax error on line 354 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'UserDir', perhaps mis-spelled or defined by a module not 
included in the server configuration

I then added the line LoadModule userdir_module /usr/local/apache2/modules/mod_userdir.so below the LoadModule access_module /usr/local/apache2/modules/mod_access.so line in httpd.conf. That eliminated the error related to the UserDir command, but I then saw another module related error message.

# ../bin/apachectl restart
Syntax error on line 382 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'DirectoryIndex', perhaps mis-spelled or defined by a module not included in the server configuration

I added LoadModule dir_module /usr/local/apache2/modules/mod_dir.so beneath the other LoadModule statements and reran apacectl restart. The error message for DirectoryIndex was eliminated and I got further in the configuration file, but I received another error message when I restarted Apache.

# ../bin/apachectl restart
Syntax error on line 403 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'TypesConfig', perhaps mis-spelled or defined by a module not included in the server configuration

So I then added LoadModule mime_module /usr/local/apache2/modules/mod_mime.so and attempted again to restart Apache. The next error message is shown below.

# ../bin/apachectl restart
Syntax error on line 456 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'LogFormat', perhaps mis-spelled or defined by a module not included in the server configuration

I then added LoadModule log_config_module /usr/local/apache2/modules/mod_log_config.so. When I attempted to restart Apache, I then saw the message below.

# ../bin/apachectl restart
Syntax error on line 506 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'Alias', perhaps mis-spelled or defined by a module not included in the server configuration

I then added LoadModule alias_module /usr/local/apache2/modules/mod_alias.so, which led to the next error message.

# ../bin/apachectl restart
Syntax error on line 576 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'IndexOptions', perhaps mis-spelled or defined by a module not included in the server configuration

I then added LoadModule autoindex_module /usr/local/apache2/modules/mod_audoindex.so and attempted to restart Apache again.

# ../bin/apachectl restart
Syntax error on line 724 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'LanguagePriority', perhaps mis-spelled or defined by a module not included in the server configuration

I added LoadModule negotiation_module /usr/local/apache2/modules/mod_negotiation.so to address that error.

# ../bin/apachectl restart
Syntax error on line 908 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'BrowserMatch', perhaps mis-spelled or defined by a module not included in the server configuration

I then added LoadModule setenvif_module /usr/local/apache2/modules/mod_setevnif.so and attempted to restart again with apachectl restart. At last it restarted without an error message. Yeah! Except when I tried telnet 1270.0.1 80 to connect to the default HTTP port on the local loopback address, it failed.

# telnet 127.0.0.1 80
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused

When I looked in /usr/local/apache2/logs/error_log, I saw the following:

[Sun Jan 27 22:09:30 2008] [notice] SIGHUP received.  Attempting to restart
Syntax error on line 219 of /usr/local/apache2/conf/httpd.conf:
module access_module is built-in and can't be loaded

So I removed LoadModule access_module /usr/local/apache2/modules/mod_access.so from httpd.conf.

But then I got the Invalid command 'Order' error message again.

# ../bin/apachectl restart
Syntax error on line 352 of /usr/local/apache2/conf/httpd.conf:
Invalid command 'Order', perhaps mis-spelled or defined by a module not included in the server configuration

I put LoadModule access_module /usr/local/apache2/modules/mod_access.so and added LoadModule auth_module /usr/local/apache2/modules/mod_auth.so below it.

# ../bin/apachectl restart
httpd not running, trying to start

I tried connecting to port 80 on the loopback address again. This time I was successful. I entered the command HEAD / HTTP/1.0 and hit return a couple of times. Apache then responded with information showing me that version 2.0.59 was running at last.

I now have the following module section in httpd.conf

#
# Dynamic Shared Object (DSO) Support
#
# To be able to use the functionality of a module which was built as a DSO you
# have to place corresponding `LoadModule' lines at this location so the
# directives contained in it are actually available _before_ they are used.
# Statically compiled modules (those listed by `httpd -l') do not need
# to be loaded here.
#
# Example:
# LoadModule foo_module modules/mod_foo.so
#
LoadModule access_module /usr/local/apache2/modules/mod_access.so
LoadModule auth_module /usr/local/apache2/modules/mod_auth.so
LoadModule userdir_module /usr/local/apache2/modules/mod_userdir.so
LoadModule dir_module /usr/local/apache2/modules/mod_dir.so
LoadModule mime_module /usr/local/apache2/modules/mod_mime.so
LoadModule log_config_module /usr/local/apache2/modules/mod_log_config.so
LoadModule alias_module /usr/local/apache2/modules/mod_alias.so
LoadModule autoindex_module /usr/local/apache2/modules/mod_autoindex.so
LoadModule negotiation_module /usr/local/apache2/modules/mod_negotiation.so
LoadModule setenvif_module /usr/local/apache2/modules/mod_setenvif.so

To get Windows Defender to accept RealVNC, select "always allow" for the action and then click on "Apply Actions".

When you are configuring RealVNC during installation, under the Connections tab in RealVNC, you can set the ports or retain the default ports that will be used for listening for connections, if you are installing the server portion of the software so you can connect remotely to the system you are installing it on. The default values are shown below:

Accept connections on port: 5900
Disconnect idle clients after (seconds): 3600

Serve Java viewer via HTTP on port: 5800

Under Access Control in the Connections section, you can check "Only accept connections from the local machine", if you wnat to require access to be through an SSH connection.

If you install the server portion of the software to run as a service on the Windows system, but don't want it to start automatically, click on the Windows Start button, select Run and type services.msc. Find "VNC Server Version 4" within the services list, double-click on it and change the startup type from "automatic" to "manual", then click on OK.

On a Windows XP Tablet PC Edition system with Service Pack 2 installed, I see the following information for the file when I right-click on it and select Properties:

At Introduction to HTML Applications (HTAs), Microsoft states the the following in regards to why someone would use HTAs:

Historically, programming languages like C++ and Microsoft Visual Basic have provided the object models and access to system resources that developers demand. With HTAs, Dynamic HTML (DHTML) with script can be added to that list. HTAs not only support everything a Web page does - namely HTML, Cascading Style Sheets (CSS), scripting languages, and behaviors - but also HTA-specific functionality. This added functionality provides control over user interface design and access to the client system. Moreover, run as trusted applications, HTAs are not subject to the same security constraints as Web pages. As with any executable file, the user is asked once, before the HTA is downloaded, whether to save or run the application; if saved to the client machine, it simply runs on demand thereafter. The end result is that an HTA runs like any executable (.exe) written in C++ or Visual Basic.

The .HTA file type can become infected by malware. It is important to note that, as fully trusted applications, HTAs can carry out actions that Internet Explorer would never permit in a Web page. Microsoft also states "In HTAs, the restrictions against allowing script to manipulate the client machine are lifted. For example, all command codes are supported without scripting limitations (see command id). And HTAs have read/write access to the files and system registry on the client machine."

Execution of .HTA files by mshta.exe can be debugged with the Microsoft Script Editor, MSE7.exe.

Messages are encrypted prior to being sent between the BlackBerry Desktop Manager software and your BlackBerry. The encryption key for the BlackBerry Desktop Manager and the BlackBerry's own encryption key must match in order for messages to be decrypted at the receiving end. Encryption keys can be manually or automatically generated.

If you are using the BlackBerry Desktop Manager for synchronization, take the following steps to generate a new encryption key:

1. Connect the BlackBerry device to the computer.
2. In BlackBerry Desktop Manager, double-click Redirector Settings.
3. In the Redirector Settings window, click the Security tab.
4. Select Generate keys manually, then click Generate. The Generating New Key window will appear.
5. Move the mouse around until the Generating New Key window closes. The random mouse movements help randomize the encryption key. When the window closes, a new encryption key has been generated.
6. If you want to be prompted to generate a new encryption key every 31 days, select Generate keys automatically.
7. Click Apply, then click OK.

Sample Playlists.Xml File

<?xml version="1.0" encoding="UTF-16"?>
<playlists playlists="2">
<playlist filename="plfE454.m3u8" title="Xmas - Hilary Duff - Santa Claus Lane" id="{C0112AC9-0575-422F-B216-9A104962C563}" songs="11" seconds="2200"/>
<playlist filename="plf7501.m3u8" title="Xmas - The Time-Life Treasury Of Christmas" id="{3463FBFD-C77E-44BD-BC13-6044D2E6BEE7}" songs="45" seconds="8327"/>
</playlists>

So, if you want to copy your playlists from one system to another, copy the .m3u8 files and the playlists.xml files from the first system to the second system.

But what if the music files, e.g. your .mp3 files, are not in the same directory on the second system as the first system? Then you will need to edit each .m3u8 file and update the reference to the actual location of the music files. E.g. if the files were on drive C:\MP3s on the first system, but drive D:\MP3s on the second system, you will need to do a global search and replace on C:\MP3s substituting D:\MP3s for it. You can use any text editor, such as Notepad, which comes with Windows, since the .m3u8 files are just text files.

If you want to change the background color for an entire row in the table, the steps are basically the same, but you need to highlight all the cells in the row before selecting Table Properties.

1. Right-click somewhere in the table.
2. Choose Table Properties.
3. Click on the Table tab.
4. Click on the Borders and Shading button.
5. Select the color you want for the table's background under Fill.

I tried another Norton Ghost 2003 boot diskette, but had the same results.

I then tried a PartImage Is Not Ghost (PING) boot CD. During the boot process I saw the following:

ata1: port is slow to respond, please be patient (Status 0x80)
ata1: softreset failed (device not ready)

PING dropped me to a shell prompt, since that was the option I picked for when it completed, without giving me a chance to start the backup. I powered the system off and on and rebooted. I did not see the messages noted above then and I was able to backup the system to an external USB disk drive.

I then tried again with a Norton Ghost 2003. This time Norton Ghost saw the drive, but when I attempted to backup the drive, I received the error below:

I tried again with a boot diskette that I had created using the Norton Ghost Boot Wizard just a couple of days ago, since the first time I used a boot CD that I had created a couple of years ago. The results were the same, however.

The next night I backed up the system with PING again and, afterwards, tried a Norton Ghost 2003 boot disc with the USB 1.1 drivers provided by Symantec with Ghost 2003.

This time I saw the error message "File Name ? (546)". When I clicked on OK, I saw the message below:

When I was dropped to a command prompt, though, I saw the following:

ABORT: 29089, Write to image file failed

ABORT: 36000, A GeneralException occurred

Hex: 25 50 44 46 2D 31 2E
ASCII: %PDF-1.

The bytes shown might be %PDF-1.4 (Hex 25 50 44 46 2D 31 2E 34), if the version is 1.4.

But there are cases where the information in the first few bytes of the file can be overridden by information appearing later in the file. Derek Clegg states at Re: How do you determine PDF version that "The version of a PDF file isn't solely determined by the first few bytes of the PDF; in PDF 1.4 and later, the version specified at the start of the PDF file can be overridden by a / Version entry in the document's catalog. (See section 3.4.1 of the PDF 1.5 specification for more info.) This is why Quartz PDF files always start with %PDF-1.3 but may, in fact, be PDF 1.4 or later."

The PDF version number determines features incorporated into the format. For instance version 1.4 was the first first to support transparency and metadata. Some older PDF viewers may not be able to view PDF files written in a newer PDF format. A listing of versions and features is available at Create better PDFs by understanding the formats.

On a Unix or Linux system, you can use the od command to view the first few bytes of a PDF file.

# od -c -N 10 EBIA_ERISA_3rdQtr2007.pdf
0000000   %   P   D   F   -   1   .   4  \n   %
0000012

The \n that appears after the "1.4" is just a newline character.

Though Windows doesn't come with a hexadecimal editor, there are free hexadecimal editors available for Windows systems as well that will allow you to view those first few bytes in the PDF file.

When the system rebooted, Windows Messenger 4.7 opened. I didn't want the software on this laptop anyway. So I opened the Control Panel (Click on Start, select Settings, then Control Panel). Under Add or Remove Programs in the Control Panel, I chose Add/Remove Windows Components. Windows Messenger was unchecked and had a size of 0.0 MB listed, so I couldn.t uninstall it that way. I was able to remove it using the steps below, however:

1. Close Messenger if it is running. If you see an icon for it at the lower-right hand corner of your screen, right-click on it and choose Exit.
2. Click on the Start button.
3. Select Run.
4. In the Open field of the window that appears, copy and paste RunDll32 advpack.dll,LaunchINFSection %windir%\INF\msmsgs.inf,BLC.Remove
5. When you see the confirmation prompt below, choose "Yes" after closing any of the referenced programs, if they are open.

   To remove Messenger, you must first exit from it: Click the Messenger icon in the taskbar, then Exit. Please also close all other programs that display your contact list (for example, Internet Explorer, Outlook, Outlook Express, MSN Explorer). Make sure to close programs for all users signed in to this computer. Do you want to continue?

You will see a notice appear stating Windows Messenger has been removed when the uninstall process completes.

If you don't want to remove Windows Messenger 4.7, but just want to stop it from running automatically when you login to a system, instead of following the procedure above, open Windows Messenger and take the following steps:

1. Click on Tools.
2. Select Options.
3. Click on the Preferences tab.
4. Uncheck "Run this program when Windows starts".
5. Click on OK.

Some malware attempts to kill or disable antivirus software processes. Pushdo does not. It merely reports back to its controlling server on which antivirus software it has detected on the victim's sysetm. Pushdo compares all of the processes running on the sysetm with its own list of antivirus and personal firewall process names and then provides a report to its controller listing the ones it has found.

In checking the Pushdo controller server, Stewart found malware samples with rootkit characteristics, which allow malware to hide from antivirus and antispyware software, and also evidence of a spam botnet.

I don't know why this problem only occurred on this user's system. Outlook 2003 opened normally on other users' systems. They were not able to access email on the Exchange server and Outlook indicated they were disconnected from the Exchange server, but they were at least able to access email, contacts, etc. that were stored in their OST offline storage files.
