I hope most of you will be up at around 2:30am Alaska time as this is when I will probably run into my errors and questions. 8^) I have my O'reilly DNS and Bind book and Gregs FreeBSD Handbook plus I can use sample configs from my own dns server and any other doc I can find. If any one else has more suggestions I would appreciate any and all. I have to try and have this setup by Monday morning and will use every reference I can find.
