Sniffer Cable Pinout

The sniffer cable is needed to connect a sniffer to an ethernet┬áhub, but not transmit any data that may reveal the sniffer’s existence. This cable will return an inverted version of anything sent to the interface. The pinout for this cable is from the book Windows Forensics, by Chad Steel (ISBN 0-470-03862-4), but can also be found at dgonzalez.net, along with other useful pinouts for receive-only cables.

Symantec’s NoNav Utility

NoNav is a utility provided by Symantec tech support. Sometimes, a Symantec Corporate AntiVirus installation fails for a client, and one of the recommended remediation practices is to remove the app manually. The problem with doing this is the number of steps in the process, including visiting hundreds of locations in the Windows registry to see if certain keys exist and if so, deleting them. For one box, this is a process. For five boxes, this is a project. You could try scripting this, or you can contact Symantec Tech support and get a copy of NoNav. This utility- Current Version 2.6- will clean out most of the settings left by Symantec Corporate versions 4,5,6,7,8,9,and 10. It should be noted that Norton (retail) products are not covered with the NoNav tool.

Running Nonav is simple, click on the executable file and it will ask for some input about what you would like to remove- Live update, virus definitions, etc. Some other input is required, options for scanning for .msi leftovers, rebooting the box at program end, and more. Each of these choices has an explanation and a recommended or not recommended note to guide the user. Let the program do some work, and if you have selected the option to do so, the machine will reboot automatically.

After the machine comes back up, you want to delete some directories left behind. These are outlined in the readme file included with NoNav- Symantec’s install directory, some shared file locations and some staging areas. Kill any that you find. Finally, delete everything in the system’s Temp directory (start, run, %TEMP%). Reboot again, and you can now reinstall the latest version of SAV and patch it to the right level.

NoNav can be acquired from Symantec Tech Support. If you have a valid support contract, call in and the technician will provide a link to download the latest version.
