Changing Page Print Order on an HP Business Inkjet 2800

Sometimes it is desirable to change the order in which pages are printed by a printer. Some printers, such as the HP Business Inkjet 2800, allow the order in which pages are modified to be selected, e.g. print first page first or last page first.

Out of Office Assistant Disabled

An Outlook 2003 user reported that she received the message "The command is not available. See the program documentation about how to use this extension" when trying to change her out-of-office message to reflect the fact that she was no longer out of the office. I found that by going to "Tools", "About Microsoft Office", and then re-enabling the disabled outex.dll add-in, I was able to correct the problem.

Configuring a Solaris 7 System to be a DHCP Server

Solaris 7 comes with software that allows it to be set up to function as a DHCP server. It is fairly easy to set up using /usr/sbin/dhcpconfig.

Calsdr.Dll Remnant

While scanning a system with ClamWin that has been performing poorly, I found calsdr.dll, which ClamWin identified as Trojan.Downloader.Rameh-1, which appears to be a remnant of a previously removed FavoriteMan adware/spyware infection.

Clocks Skewed

I found entries in a Windows XP system's application log stating "the clocks on the client and server machines are skewed" and entries in the application log on the server referring to Kerberos problems stating "the ticket used against that server is not yet valid (in relationshiop to that server time). Contact your system administrator to make sure the client and server times are in sync". I found the problem was due to the fact that the Windows Time service, aka w32tm, was not running on the server, which was the domain controller for the domain.

cal

On Linux systems and Unix systems you can use the cal utility to view a calendar. If you type cal, you will see a calendar for the current month.

     April 2005
Su Mo Tu We Th Fr Sa
                1  2
 3  4  5  6  7  8  9
10 11 12 13 14 15 16
17 18 19 20 21 22 23
24 25 26 27 28 29 30

If you want a calendar for another month, either in the past or the future, you can specify the month and year with cal mm yyyy. E.g. to view the calendar for February 2005, you could use cal 02 2005.

    February 2005
Su Mo Tu We Th Fr Sa
       1  2  3  4  5
 6  7  8  9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28

You can view the calendar in Julian format with the -j option, i.e. produce a calendar that shows the number of days that have elapsed since the start of the year with January 1 as day one and February 1 as day 32. E.g. cal -j 02 2004 produces a Julian date calendar for February 2004.

       February 2004
Sun Mon Tue Wed Thu Fri Sat
 32  33  34  35  36  37  38
 39  40  41  42  43  44  45
 46  47  48  49  50  51  52
 53  54

If you need more features from a calendar display program, you can try the GNU gcal program or the pcal and lcal programs, which can generate postscript and html output.

antixls

I needed the capability to convert Microsoft Excel spreadsheets sent to my email account on a Linux system to a form I could work with on that system. The spreadsheets contain just email addresses that I need to put into a text file for a mailing list on the Linux email server. I wanted something simple and straightforward to use. I didn't need a lot of bells and whistles, just the capability to convert the data in the .xls spreadsheet file to a text or CSV file. I found antixls, which can be downloaded from the author's site at http://www.af0.net/~dan/?antixls, which suited my needs perfectly.

Antixls is a small Perl script that can display the information in a spreadsheet in a number of modes, including in ASCII art format, "linear" (unformatted), CSV, and linearly with cell indices, which is the default mode. The antixls Perl program provides a wrapper for Kawai Takanori's Spreadsheet::ParseExcel module.

Help on using the script can be viewed by typing antixls --help.

Usage: antixls [options...] excelfile1 [excelfile2 ...]
General Options:
--help                  This help information
--version               Show version information
--formatted             Display sheets in ASCII-art table
--linear                Display sheets in "linear" (unformatted) mode
--csv                   Display sheets in CSV mode
--indexed               Display sheets linearly with cell indices (default)

I wanted to convert the membership spreadsheet to text or CSV format. I found that converting to CSV format with antixls worked, since afterwards I only needed to remove the comma at the end of each line with vi to put the email addresses in the text format I needed of one addres per line. Linear (unformatted) mode would also have worked well. As examples of the output from the program, below I've included the output in the formats the program can use for output. I placed the commands that produced the output above the output. The actual email addresses have, of course, been altered.

Finding A PGP Key

If you need to locate someone's PGP key on a PGP server using gnupg, you can use the command gpg --search-keys --keyserver <servername> <name>, where "servername" is the name of the PGP server where the key is stored and "name" is the person's name. For instance, suppose the person's last name is Pacheo and the applicable key server is server1.somewhere.com, then you would use gpg --search-keys --keyserver server1.somewhere.com pacheo. If there were multiple keys on the server that matched, you would see a numbered list of all matching keys and would be prompted to enter the number for the one you want. Once you select the one you want, you should see a message indicating the public key for the person has been imported to your keyring. If you issue the command gpg --list-keys, you should see the new key listed.

If the email address associated with the new key was pacheo@abcxyz.com and you wanted to send the file confinfo.xls as an encrypted attachment to an email to the person, you could use gpg --encrypt -r pacheo@abcxyz.com confinfo.xls. Gnupg would then create a new encrypted version of the file called confinfo.xls.gpg, which you could attach to your email. The recipient, who you specify with the "-r" option, would then need a program on his end, such as gnupg, PGP, etc. that could decrypt the file, producing a duplicate of the original confinfo.xls file.

In the above example, you would be using the person's public key to encrypt the file. Only someone who has the associated private key, which should only be that person or someone he very much trusts, will be able to decrypt the file. You don't need his private key to encrypt the file, only the public key, which he can make available to anyone via the key server.

PayPal Phising site at www.paypal.com.sdll.us Gone

I see that the website, www.paypal.com.sdll.us, that was being used on Monday for a PayPal scam (see PayPal Phishing Attempt at www.paypal.com.sdll.us) has been taken down. Hopefully, the person running the spoofed site has been identified.

Fixing "To" Addresses in a Queued Message

If a message is stuck in a sendmail mail queue and you can tell that it is because of an invalid "to" address, you can correct the problem by editing the appropriate "qf" queue file. For instance I saw a message queued the day before addressed to an address similar to john_castle@senate.state. Obviously, the sender left off the end of the address, which should have included the state abbreviation followed by .us. Since senate.state is not a valid domain name, sendmail assumed that senate.state.com was the intended domain name. A server with that name existed, but wasn't accepting email, i.e. it wasn't listening for connections on port 25 But as far as sendmail was concerned the delivery problem might only be temporary, so it would keep trying to deliver the message for five days before giving up and bouncing the message back to the sender.

The queue id for the message was j35DxWRb002888. Since sendmail stores the "envelope" information for messages in queue files in /var/mail/mqueue with filenames beginning with "qf", I used vi to edit qfj35DxWRb002888. I replaced senate.state.com with the appropriate address and replaced all occurrences of senate.state with the correct address.

If you then want to have sendmail attempt to send the queued message immediately, you can use "sendmail -q 0 -v" to have sendmail attempt to process all queued messages once immediately. The "-q" specifies the time with zero instructing it to do it now and "-v" displaying verbose results, which will allow you to see the process of sendmail connecting to a recipient's email server and attempting to deliver the message (you might not want to use the "-v" option if you have lengthy queues).

WildTangent Web Driver

Checking a system with poor peformance using Spybot Search & Destroy, I found WildTangent Web Driver, but it did not appear to be the source of the problem and as far as I can determine isn't a significant security risk or system destabilizer.

PayPal Phishing Attempt at www.paypal.com.sdll.us

I received three copies of an attempt to garner PayPal account information today. The spoofed PayPal site was at http://www.paypal.com.sdll.us/webscr/index.html. The phisher used a JavaScript technique for overlaying Internet Explorer's address bar with a URL pointing to the real PayPal site, making it appear that anyone clicking on a link in the message had gone to the real site, whereas they would actually be at the spoofed site.
