Running snort 2.1.0. I've modified the icmp-info.rules to be of the following form:alert icmp !$TRUSTED_NET any -> $HOME_NET any (msg:"ICMP PING"; itype: 8; icode: 0; sid:384; classtype:misc-activity; rev:4;)
and have the following NET definitions in snort.conf:var TRUSTED_NET [65.171.192.0/24,192.168.0.0/24,65.104.69.192/27,207.202.149.0/24,12.105.80.64/27,69.9.9.160/27]
var HOME_NET [65.171.192.0/24,192.168.0.0/24]but I'm still seeing the ICMP PING (and other) alerts showing up in my ACID console.
from the alert log: [**] [1:384:4] ICMP PING [**] [Classification: Misc activity] [Priority: 3] 01/08-16:44:11.055633 65.104.69.201 -> 65.171.192.100 ICMP TTL:253 TOS:0x0 ID:65224 IpLen:20 DgmLen:1500 DF Type:8 Code:0 ID:0 Seq:0 ECHO -- Orion Poplawski System Administrator 303-415-9701 x222 Colorado Research Associates/NWRA FAX: 303-415-9702 3380 Mitchell Lane, Boulder CO 80301 http://www.co-ra.com ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
