First off: Excellent tutorial, thank you very much. i've been having so many problems with slow DNS lookups - just what I needed.
Also - if you have an 'always on' internet connections, and want to automate the updating of root.hints add this to the /etc/crontab file (it's 2 lines, may wrap a lil cause they are long lines):
Code:
# update DNS cache root.hints on the first of every month at noon
0 12 1 * * root dig @h.root-servers.net . ns > /var/named/root.hints
of course, replace h.root-servers.net with the name of the server that you are using.
once the file is saved cron will restart itself when it sees the newer file date.
that's it. It'll take care of itself forever now.
