[OPLINTECH] Network Port Scanners

[Chad Neeper]

nmap (www.nmap.org) is the defacto standard port scanner in the linux 
world. It has also been ported to Windows and has a GUI front-end to 
make it a little more palatable for people less familiar with command 
line arguments. Very powerful. Not for the faint at heart.

Wireshark (www.wireshark.org) might also prove useful to you. Hugely 
powerful, it can provide huge insights into how your network operates.

These tools have been actively developed for years and are very well 
supported.

People have made careers out of support at this networking level; it can 
become rather complex. However, if you can get at least a basic 
understanding of how your network really operates, the 
knowledge/experience can be very valuable.

Two cents,
Chad
