One of the things that really bugs me about online tutorials is that find one that’s accurate is a major pain. Recently I have to figure out (again) how to get secure dynamic DNS updates working with nsupdate and Bind9. Since I haven’t done this in nearly 3 years now, I had forgotten several important steps. In the hopes of saving someone else time (and mine in the future should I forget in the future). In truth getting this setup is relatively simple - you just have to know the right set of steps in order to get it done right.
For this tutorial I’ll be using the Ubuntu 12.04 and Bind9 from upstream.
