Hi there I wanted to alter on connection which have set TERM to e.g. xxx So I tried: alter tcp $EXTERNAL_NET any -> $HOME_NET 23 (msg:"does not really matter"; content:"|fffa 1800|"; tag: session, 1000, packets;) But the f$%^ thing does not work as soon as I put the content option in. I got no idea why this does not work.
Try adding rawbytes; at the end of the content in your rules. Option negotiation codes are normalized away by default. The rawbytes option allows you to match the raw pattern data. -- Chris Green <cmg () sourcefire com> Warning: time of day goes back, taking countermeasures. ------------------------------------------------------- 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
