Re: IP REP / Pulled Pork / Snort Difficulties

[Anshuman Anil Deshmukh <anshuman () cybage com>]

Hi YM,



So to have two configurations, we should have 2 pulledpork config files, right? Also if you could elaborate what goes 
wrong by not having 2 configs would help.



Thanks.



Regards,

Anshuman

Hi Bradley;

What I have noticed is that the ability to process IP lists "offline"/locally as PulledPork would with rulesets  dose 
not seem to be implemented. If it is, then both of us are making the same mistake :).  What I do is that I run 
PulledPork twice, once against the configs to process rulesets locally,  and the second time against configs to only 
fetch the IP list and process it.
