Viewing Full Message Headers in Outlook 2007

There are occasions where you may need to view the full message headers of a message that you have received in Outlook 2007, e.g., if you need to determine if a message actually originated from the "from" email address used in the message, since "from" addresses are easily spoofed by spammers. The full message headers, which reveal the origination IP address for the message and the email servers through which the message has passed, are, by default, hidden in Outlook. To reveal them take the following steps.

PRTG Network Monitor

If you would like to use a Microsoft Windows system for Simple Network Management Protocol (SNMP) or Windows Management Instrumentation (WMI) monitoring of systems, Paessler AG provides a free edition of their PRTG Network Monitor software, that provides a lot of capabilities, though there is a limit of 10-20 sensors with the free version (you can increase the default limit from 10 to 20 by putting a small banner for the program on your website). But for small businesses or personal use, that may provide all of the monitoring capability you need.

The company also provides other free SNMP and network tools at Free network tools for system administrators

Obtaining the CPU Speed from a Command Line

You can obtain the CPU speed from the command line on a Windows system, such as a Windows XP or Small Business Server (SBS) 2003 system by using the command wmic cpu get CurrentClockSpeed. Note: when you first run the command, you may see "Please wait while WMIC is being installed." or "Please wait while WMIC compiles updated MOF files." You may have to wait a few minutes before seeing the results, but the next time you issue a wmic cpu get command you shouldn't have that delay. Also note that this command is not available on Windows 2000 or prior versions of Microsoft Windows.

The clock speed will be displayed in MegaHertz (MHz); if you want the value in GigaHertz (GHz), just divide by 1,000.

C:\>wmic cpu get currentclockspeed
CurrentClockSpeed
1300

In the above case, the speed is 1300 Mhz, which is 1.30 GHz. The 1.30 GHz value could also be obtained through the Windows Graphical User Interface (GUI) by clicking on Start, selecting Control Panel, and then System on a SBS 2003 system.

You may also be able to get the processor speed along with the name using wmic cpu get name, but the speed won't necessarily be displayed on all systems. The name will tell you whether it is an Intel or AMD processor.

C:\>wmic cpu get name
Name
Intel(R) Celeron(R) CPU 1.80GHz

The following information was returned for a system with an AMD processor.

C:\>wmic cpu get name
Name
AMD Duron(tm)

jqs.exe

I checked the running processes on a Windows XP Professional system with the tasklist command. I saw a process, jqs.exe, I didn't recognize. I searched for its location on the hard drive and found it at the following location.
C:\>dir /s jqs.exe
 Volume in drive C has no label.
 Volume Serial Number is 4CA9-07E6

 Directory of C:\Program Files\Java\jre6\bin

07/17/2010  05:00 AM           153,376 jqs.exe
               1 File(s)        153,376 bytes

     Total Files Listed:
               1 File(s)        153,376 bytes
               0 Dir(s)  14,939,205,632 bytes free

At JQS.EXE, I also found that the process is associated with Java.

Experienced computer users might guess that the process is related to Java and that is the case indeed. Jqs.exe is the Java Quick Starter which was designed to improve the startup time of Java applets and applications by prefetching Java Runtime Environment (JRE) files frequently into memory. That's mainly interesting for users who work with Java on a day to day basis. Everyone else might be better of disabling the Java Quick Starter. Think of a user who encounters one Java applet per month (or week), would it make sense to run the process all the time because of those few instances where it might start the application or applet faster? (see also Java Portable on how to use a portable version of Java on the computer)

Jqs.exe is definitely querying the Windows Registry for instance. The performance increase might not be huge but you will free up some computer memory and some I/O processes on the computer system.

When I checked, I found jqs.exe was using about 2 KB of memory on the system.

C:\>tasklist /fi "imagename eq jqs.exe"

Image Name                   PID Session Name     Session#    Mem Usage
========================= ====== ================ ======== ============
jqs.exe                     1740 Console                 0      1,824 K

The ghacks.net webpage also provides instructions for disabling the Java Quick Starter (JQS), if you wish.

Now, if you want to disable the Java Quick Starter process you can do that in the Windows Control Panel. You find a Java entry there which will open the Java Control Panel.

A click on Advanced and the selection of Miscellaneous will display the activated Java Quick Starter entry. Uncheck the box to disable the process. This will be visible in the Windows Task Manager immediately.

You might also be interested in finding out how to run Java Portable which is another option to make sure that no background processes are running.

The image below shows the "Java Quick Starter" option under the Miscellaneous section of the Java Control Panel. Unchecking that option will keep jqs.exe from continually running, if you don't feel you need the Java Quick Starter to be running.

Keys to Enter BIOS and Select Boot Menu

I often need to know what keys to hit to enter the BIOS setup routine or to select the boot menu on various systems, so I thought I would start a table today to hold that information, which I will update anytime I find myself needing that information for a particular system. The table is here.

Scan of Windows XP System on 2010-10-03 with Verizon Internet Security Suite

I ran a scan of a Windows XP Service Pack 2 system with an up-to-date version of Verizon Internet Security Suite on 2010-10-03. The software, which states it is "Powered by McAfee" reported the following:

During the full scan, McAfee detected one item that requires your attention. View the scan details to fix this issue now.

Results
Items Scanned: 324912
Items Detected: 88
Items Fixed: 87
Items Remaining: 1

Potentially Unwanted Programs Adware-Url.gen

Files Affected
C:\Program Files\Free Offers from Freeze.com\afactory.url

C:\Program Files\Free Offers from Freeze.com\graflatscreen.url
C:\Program Files\Free Offers from Freeze.com\pcpowerscan.url
C:\Program Files\Free Offers from Freeze.com\spcasino_sep.url

I chose to have Verizon Internet Security Suite quarantine the files. When I checked on what else it had found, I found it reporting it had quarantined an instance of Spy-Agent.bw!zip, which it found in a file, bill.zip, that it found at C:\Documents and Settings\Jeanne\My Documents\Email\Embedded\bill.zip, i.e., it appeared to have quarantined an attachment to an email message. There was no indication that the file had actually led to any infection of the system, just that a zip file containing the malware had been detected. The webpage for that malware contained a link to a McAfee webpage Spy-Agent.bw, which indicated McAfee first discovered that malware on August 20, 2007.

The scan also found a lot of cookies wich the antivirus program deleted, but I consider those fairly innocuous.

Obtaining the Version of OS X from the Command Line

To obtain the version of OS X from a command line, i.e., from a Terminal window, you can use the command system_profiler SPSoftwareDataType
.
$ system_profiler SPSoftwareDataType
Software:

    System Software Overview:

      System Version: Mac OS X 10.3.9 (7W98)
      Kernel Version: Darwin 7.9.0
      Boot Volume: Macintosh HD
      Computer Name: john  smith's Computer
      User Name: JOHN SMITH (jsmith)

The above command provides both the version of OS X, which is 10.3.9 in the example shown and the kernel version, which is 7.9.0. To view just the version of OS X, you can use the command sw_vers -productVersion.

$ sw_vers -productVersion
10.3.9
$

If you needed the version of the kernel, you can also use the traditional uname -a command used on Unix and Linux systems or uname -r to get just the kernel version.

$ uname -a
Darwin joe-smiths-Computer.local 7.9.0 Darwin Kernel Version 7.9.0: Wed Mar 30 2
0:11:17 PST 2005; root:xnu/xnu-517.12.7.obj~1/RELEASE_PPC  Power Macintosh powerpc
$ uname -r
7.9.0

To match a version number to a codename, e.g. OS X 10.3 has a codename of "Panther", see the table below.
