DNS

Larousse, albert and zwinger are listed as authoritative name servers for *.pmtpa.wmnet. Larousse and zwinger are running PowerDNS. All three are running named.

Important files

/var/named/master/wmnet.zone 

This is the internal zone, it's the equivalent of /etc/hosts before we massacred that file

/var/named/master/wikimedia.zone 

This is the list of names available externally under *.wikimedia.org

Edit one of these files on zwinger, and then restart with /etc/init.d/named restart.
