Check out tcpdump. It will allow you to log packets on the
networks and write them to a file that can then be read with
tcpdump and perused at your lesiure. I believ it is on the
redhact install cds.
I usually usea variant of :
tcpdump -w /tmp/firewall.tcpdump
This will capure all traffic and logit to a file called
firewall.tcpdump in the tmp directory.
You can then read the file with
tcpdump -r /tmp/firewall.tcpdump | less
You can do quite bit of filtering based on protocols and
hosts to make it a little easier to find out what is
happening.
Tha man page is not bad.
