Okay, thanks, I see what you mean. I tried that too but still manage to pick up attack traffic to another host. Here is the scenario: Suppose the host that has snort installed is 192.168.1.10, and i set my HOME_NET to 192.168.1.10/32. Then i tried to use another machine 192.168.1.20 to nmap another machine 192.168.1.30, the snort on 192.168.1.10 still can pick up the traffic and generate alerts. I understand that snort is more of a Netword based IDS, but lets assume that i'm in a sad case where I can't even trust my neighbours in the same network. what other configuration needs to be done?
Honestly it sounds like a misconfig issue. Once you make the change in snort.conf, are you restarting Snort? If you're not, you need to. What is your EXTERNAL_NET set to? If it's still at 'any' change it to '!$HOME_NET'. Cheers! ----- Erek Adams "When things get weird, the weird turn pro." H.S.
