Hello Pen-Testers:

Some time ago, NGSEC released a command line sniffer for win2k or higher (no packet driver requeired). It was developed for penetration tests once you have access for a cmd.exe shell.

Download it at:

              http://www.ngsec.com/ngresearch/ngtools/

Succesfully we got lot of feedback, and so we were forced to improve it with your ideas/coments.

CHANGELOG for 1.1:

- ------------------

- - Better command line options parsing.

• - Command line options (--help, --list-interfaces, --interface, ...)
• - File logging (--file <file>)
• - Display packet from only one host (--only-host)
• - Minor bugs fixed.

Hope it would be useful :P

Here is a sample output (again):
