AW: 3 or 4 NICs in a sensor?

I ran into the same problem. I would highly recommend separating snort from doing anything else than IDS sniffing. Even writing into a db should not be handled by snort but by barnyard leaving snort in high speed logging using unified format. Just my $0.02 Ciao, Sandro
I run three incidences of snort on one box. I use three different command lines to run on eth1, eth2 and eth3... Ethernet 4 is my management port. So I have 4 nics in the box and all runs just fine. My only problem seems to be when I get alot of alerts in the MySQL database cleaning them up takes the system to 100% cpu utilized. And Acid times out. I am beginning to look for possibly some other boxes to run the sensors on and have 1 box just for the MySQL and ACID interfaces.

My currentsensor is notexposed to heavy traffic and I was considering adding moreNICs to the boxso I can have it monitoring other segments at the sametime, rather thanbuild more sensors. Is anyone out there running Snort on abox with say, 4NICs, where 3 of the NICs are each running their own Snort instance, monitoring different network segments? If traffic is lightenough on eachsegment, it seems better not to waste extra hardware andbuild separatesensors. I wanted to get an idea if others are doing this, is itwise to do it, willit work etc? Thanks!
