i'm currently workign on getting snort up and running. i'm getting it to work with mysql and acid. as of now, it seems to be working, but if i portscan my computer, it won't detect it. and it only seems to be detecting random icmp packets. which is odd b/c i'm supposed to be blocking those using iptables and so i can't even ping myself:
Chain INPUT (policy ACCEPT)
target prot opt source destination
DROP icmp -- anywhere anywhere
i assume because i'm getting feedback from acid, that snort is actually communicating with my sql server and acid is getting those results. but they're not the one's i'm looking for.
i currently have all the rules for snort enabled, recently downloaded, and the threshold.conf file disabled. whats going on here?

the source address for the top one, icmp destination unreachable, are from my computer to my computer. which makes sense since i tried to ping myself after putting in the iptables thing.
that's all i have after a nikto scan and like 3 port scans. the only thing that shows up should be something that shouldn't be showing up.
UPDATE: it also began detecting my AIM converstaions....as it should have. so i had a bunch of tcp alerts in there telling me i was using aim. i have since shut it down. but still, other than that, all it picks up are icmp packets. i ahve also since flushed my iptables just to make sure they don't interfere with anything i'm doing with snort.//
