cxtracker - (Connection Tracker) is a passive network connection tracker
for profiling, history, auditing and network discovery. It can be used
as an replacement for sancp in the sguil setup. It handles vlan (2 layers)
and IPv6 out of the box.
CxTracker is available as a
tar-
or zip-ball,
but you can also clone it with git.
We recommend the cxtracker 0.9.5 release which should be available here.
