[Snort-users] Snort not loading dynamic rules?

I think you pasted the same thing twice.

Dynamic rules, as listed below, are the "Activate/Dynamic" rules.  not the SO rules.  Therefore, if you don't have Dynamic rules, it will always read 0.  VRT ships zero Dynamic rules.  So, if you are running the VRT ruleset, you will have 0 there.

Matter of fact, I don't think anyone ships dynamic rules.  I don't know anyone that uses them.  (Not saying there isn't, I've just never ran across them)
