Paranoid Penguin - DNS Cache Poisoning, Part II: DNSSEC Validation
And with that, your nameserver is successfully validating signed zone data! For now, I wish you thanks and goodbye. As I seem to do every couple years, I'm going to take a hiatus for a few months. I do plan on resuming the Paranoid Penguin after that, however, refreshed and renewed for your reading pleasure.
Until then, take care of yourself and especially your Linux systems!
