You are just disabling the alert.

If I place an entry in the disablesid.conf. For example: 129:12

It does take the preprocessor out of the snort.rules file.

Would that be ok or am I going to break something?

Thanks,

Aren't they now rolled into the snort.rules file in the VRT-preprocessor Rules Category? I no longer push a preprocessor.rules file to my sensors. I'm using pulledpork v7.

Thanks,

    Other than suppressing in the threshold.conf file on each sensor, what is the best way to disable a few of the preprocessors by Sid #? I've searched and nothing I'm reading is very clear.

You could comment them out in preprocessor.rules.

I'm using pulledpork, but would placing a disable in the disablesid.conf work for a preprocessor?

I think so, but I’m not 100% on that, I’d defer that questions to JJ.

I've read mention of modifying the snort.conf but I don't see how you would block an individual Sid.

If the only option is the threshold.conf, is it possible to do an include statement in the file, so I would then push out a universal set of suppressions to all my sensors and beable to update them all at once.
