Well the thing is... I have worked out how to swicth between
"online" and "offline" modes...actually simple...
the idea is to have 2 dirs /var/named-online and /var/named-offline
then have /var/named a sym link to the proper one.
in the same script that changes the sym link issue
kill -SIGHUP `cat /var/run/named.pid`
My question is on how to setup named so that it is capable of answering the
queries of my machines about eachother
(ie if kitty wants to resolve shit-box.carpanet to check out the
web server)
