How to setup a Tertiary DNS server
 

Hello.. :)..We have an existing Primary and Secondary DNS server (BIND) and would like to setup a Tertiary DNS server. My question is what would be the tertiary's configuration? Will it be the same as the secondary server? What do I need to add to the Primary server (zone and db file)?

thanks in advance...

A Tertiary DNS Server is a second secondary server. That is, a server that gets all of its authoritative information from the primary server. Setup same as secondary. Just remember to define it as authorized for zone transfers on the primary server if you have that restriction set.

Thanks for the response Suncoast :).

Just for clarification on the Primary setup. If I have a domain, I need to define two "slave" pointing to both secondary server ? (ex: allow-transfer {first ip add; 2nd ip add;}

thanks again :)

I'd have to look at my setups to confirm that syntax, but you have the right idea. I thought the parameter had the word zone in it... It's really late, and I just spotted your question. Many sites do not restrict who can request DNS zone transfers. Only time it's really needed is when you have internal hosts registering their IPs with external bind servers, and naturally you don't want that info to go out into the wild. So if you are currently restricting zone transfers, there is a parameter that will have the current ip address of your current secondary server in your existing primary bind config. This is where to add the new server. If it's not listed, you should be able to setup the new server and just point it to the primary and it will just pop up populated with all the info. Hope I'm making sense.

Sorry for the ramble.
