source of attack was 216.241.67.74. Destination was 10.1.1.10
Here is a theory. The filter "not src host 10.1.1.10" makes Snort see only packets in one direction when attacking from 216.241.67.74 -> 10.1.1.10, so Snort never gets that this is actually an established session. Since -z i specified, no alert is generated (which should probably be regarded as correct). What do you think? What happens if you run without -z? /Andreas ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ 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
