    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):
