We have three DNS servers:
Modify records for a domain
On Backus, edit:
/etc/bind/db/<type>/<domain>.zone.
Remember to increment the zone's serial number!
Flush DNS cache
$ sudo rndc flush
Update records when using dynamic DNS
At LANs we tend to like to use dynamic DNS so we can refer to PCs by names. To update service-oriented records:
$ sudo /etc/init.d/bind9 stop $ sudo vim /etc/bind/db.compsoc (Add CNAMEs, etc.) (Update serial) $ sudo rm /etc/bind/*.jnl $ sudo /etc/init.d/bind9 start
