Re: pass rules for one alert

That pass rule (if run with snort -o) will cause all ftp command channel data that is in a single packet >100 bytes to be completely ignored.
My suggestion is just disable the rule that's causing your false alarm problem by commenting it out with a #.

Hello everybody, I have a simple question:I want to ignore exactly one rule, that triggers false positives from one host to another. To do so, I wrote an pass-rule like that:pass tcp <source-ip> any -> <dest-ip> 21 (msg:"FTP command overflow attempt"; flags:A+; dsize:>100; reference:bugtraq,4638; classtype:protocol-command-decode; sid:1748; rev:3;)I don't want to ignore all FTP-Data between these hosts, only the FTP-Data that triggers this alert (thats means the pass-rule:pass tcp <source-ip> any -> <dest-ip> 21 isn't precise enough. And ignores all FTP-Data.)Is it possible to ignore exactly the FTP-Data between these Hosts, that triggers that alert. I want the other FTP-Data between these Hosts being scanned for other FTP-Exploits except the "FTP command overflow attempt".System: Debian 3.0 x86, snort 1.8.7, ACID, MySQLSnort-Options: snort -c /my/way/to/snort.conf -d -D -e -g snortgroup -i eth0 -o -u snortuserInterface: eth0, no IP-Address Thanks Addy __________________________________________________________________The NEW Netscape 7.0 browser is now available.
