hi, There was a question regarding the below rule: (but didnt find any replies) alert icmp $EXTERNAL_NET any -> $HOME_NET any (msg:"ICMP L3retriever Ping"; content: "ABCDEFGHIJKLMNOPQRSTUVWABCDEFGHI"; itype: 8; icode: 0; depth: 32; reference:arachnids,311; classtype:attempted-recon; sid:466; rev:1;) Is there any particular reason for this alert ?? The lone fact that content has "ABCD..." does 'nt require much attention, right ? and such a rule might cause false alarms, correct ? Pls correct me if i am wrong. cheers ashley _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
