I'm running libpcap-0.8.3-10.RHEL4. Is there a significant advantage to running something other than RedHat's libpcap?
Yeah, Phil Wood's libpcap is significantly more efficient.
I have to admit, I don't like messing with RedHat's package dependencies. They're not especially forgiving.
If you build properly-versioned RPMs, about the only thing you need to watch out for is Red Hat's upstream packages gaining a security fix that isn't present in the version you're using (as yum and friends will correctly avoid "upgrading" that package).
In this case I want to avoid having a single sensor and rule set for both interfaces, since the traffic is dissimilar (one is internal, one is at an edge). I would rather build out a new sensor on a separate box if that's what it comes down to.
That's another option, also.
