Anyone here using IP Audit Web?
http://ipaudit.sourceforge.net/ipaudit-web/

It is supposed to be similar to Cisco NetFlow...

I'm working on configuring an older box to throw at my gateway to see how it works.
Looks pretty useful.

I seem to remeber this project from a while ago... but it got lost on my to-check-out list.

Security Focus just reminded me about it today with a nice little article/intro about it
