Re: threshold.conf global suppression by IP

[Mitch Gates <MGates () americanbus com>]

I am running 2.9.8.3 - here is the syntax I am trying to use, to be specific:

suppress gen_id 0, sig_id 0, track by_src, ip 1.1.1.0/24

It seems that if I have one global suppress the service will start and run - if I try to do multiple lines for multiple 
IP addresses it won't start, such as:

suppress gen_id 0, sig_id 0, track by_src, ip 1.1.1.0/24
suppress gen_id 0, sig_id 0, track by_src, ip 2.2.2.0/24

Any ideas on how to get this to work with multiple IP addresses?

IIRC gen_id 0, sig_id 0 was added a few years ago. Make sure your running the latest version (2.9.8.3).

Hmm, the documentation clearly states that gen_id 0, sig_id 0 can be used with suppress. Can you get exactly what 
causing the service to not run?



I just did a quick test and snort seems to run fine. I put this in my threshold.conf

suppress gen_id 0, sig_id 0

Yes you can set a global filter among all rule types (text, so, etc). To do this, your event_filter should have:

gen_id 0, sig_id 0

If you want to address text rules only, then

gen_id 1, sig_id 0

and so on.

Is there any way I can suppress events globally from a dst or src ip rather than defining each individual gen id and 
sig id I want to suppress?
