Has anyone ever noticed that this signature seems to be triggered by NCP in Netware 5- I just set up a Snort box and I'm getting alerts from Netware servers originating at port 524, netware's NCP request port. here is the rule: alert ip $EXTERNAL_NET any -> $HOME_NET any (msg:"SHELLCODE x86 NOOP"; content: "|90 90 90 90 90 90 90 90 90 90 90 90 90 90|"; depth: 128; reference:arachnids,181; classtype:shellcode-detect; sid:648; rev:4;) is there anyway to make it better and eliminate this false positive other than telling it to ignore those servers and/or ports? thanks Yonah _______________________________________________ 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
