Re: Preprocessing rule blocking

Never mind. This sensor is at remote location that is having network issues and it's actually still writing data into 
the database that is two days old. So I'm just chasing my tail here. I bet it's working be ause the suppression is 
working at another location.  

Thanks,
Ed

I decided to try to suppress using:

Suppress gen_id 137, sig_id 1

But suppression doesn't seem to work, after restarting snort the alerts still get through. 

If I try at the snort.conf by commenting out the preprocessor wouldn't I be suppressing all SSL alerts? 

Thanks,

Hi All,
   If I want to limit or block all reporting on Snort Alert [137:1:0]

Would this work to limit it to one for every minute via the threshold.conf. Is there an easy way to block it all 
together?

event_filter \
  gen_id 137, sig_id 1, \
  type limit, track by_src, \
  count 1, seconds 60

yes, that will limit is to one alert every minute...

to disable it completely, you might comment the rule out in your 
preproc_rules/preprocessor.rules file if you are using that... i /think/ that's 
where the stub is located...
