Russell,I am at the point where I need to have more than one snort instance running on a given sensor so we can take advantage of multiple CPUs and thus I will be producing multiple unified2 files on a sensor. Logically there is still just one sensor...*Physically* there is still just one sensor. *Logically*, there's two now... they just happen to occupy the same physical space. I'll echo the advice of others and say that most front-ends handle this gracefully. Are you using custom processing scripts that make hard-coded assumptions about the sensor-id, or something standard? All of the front-ends I've tested handle multiple sensors fairly transparently. I didn't even notice the difference migrating from 1 to 4 and then to 5 snort-procs with either Base or Placid.
Thanks Mike, et al! :) I'm using placid and already have it set up with to merge some stuff so it isnt a big deal. What I currently have is several logical sensors and use a different placid instance for each and list the sids in the conf (this is a recent addition). Just wanted to make sure that my understanding of Barnyard2 was correct.
