Re: SSH MISMATCH

["Jefferson, Shawn" <Shawn.Jefferson () bcferries com>]

Pre-processors rules are "built-in" to snort, and when you compile snort you can specify that you want to enable 
pre-processor rules (I typically use --enable-sourcefire which enables some other options you'll most likely want as 
well.)  Then you need to have the pre-processor rules files specified in your snort.conf as well.  You can then disable 
rules in these files like you mention.  Make sure to -HUP snort to get it to re-read the rule config (I'm pretty sure 
that works for pre-processor rules as well-someone correct me if I'm wrong.)

Subject: [Snort-users] SSH MISMATCH

i am trying to turn off this alert in preproc_rules/preprocessor.rules:

#alert ( msg: "SSH_EVENT_PROTOMISMATCH"; sid: 4; gid: 128; rev: 1;
metadata: rule-type preproc, service ssh ;
classtype:non-standard-protocol;)

i commented it out, still it shows up in base.

which leads to another logical question: 

how can one find out where a rule lives in the first place.
i figured out from base if i mouse over the snort portion it states:
128-4 which i figured you can grep 128 goto the file, 4 entries down, find it that way.

1. is there another easier way to find them?

2. lastly, how can i turn it off 128-4 for good.

thanks
