[TriLUG] Help with caching dns server

[Peter Long]

Are you sure you are using  your new DNS rather than OpenDNS? What does your
/etc/resolv.conf have in it on the machine you are pinging from? Perhaps it
is not looking up www as www.home.linux, but rather attaching your
dyndns.com domain suffix. There should be something like:

search home.linux
nameserver 192.168.0.1
domain home.linux

in the /etc/resolv.conf.

Just a guess.
