intrusion detection software.


I have a nice linux software called opmanager. It does nice graphs etc, on
my linux machine, for my whole network of about 8 pc;s tivo etc.

My linksys firewall router sends back snmp traps that are logged in txt
Date time sender IP.port and receiver ip.port. tcp/udp.

Wal watcher a windows app does a nice job of IDR. but it is windows only.
I would like something like it for linux. any ideas.
