Named
From Nuclear Physics Group Documentation Pages
Named serves DNS records
Named is the deamon that provides DNS services. It runs on einstein, and should be running on roentgen and endeavour, but that needs fixing.
The configuration for DNS is in /etc/named.conf
The entries for the DNS are on einstein in /var/named/
After making any edits, make sure you reload the tables: /etc/init.d/named reload
There is still some legacy "Aaron" stuff in there that should be cleaned up. He should be working on moving the entries to other systems.
