Would these DNS dampening,
rate-limiting and anti-spoofing techniques work with PowerDNS?
Obviously, Snort IDS, and Shoreline Firewall, SELinux and AppArmor are all good, and disabling SU (use sudo only) and using a makejail chroot jail for every service (including bind or pdns, whichever) would be wise, however what can you do in terms of dampening, rate-limiting and other anti-amplification precautions can you take with powerdns?

contains the rate limiting patch. I will be compiling the bind9
testing package on a stable base and testing it shortly, if the
package seems to work fine I will make it available.

I have not built bind with Dampening yet, I just got the RRL patch going last night. Will try to deploy an instance of the dampening patch perhaps tonight.
