Secondary DNS

[bizzaro]

I have a public DNS server running bind. I would like to sign up for a secondary DNS service to take over if my primary bind server fails. Besides listing the secondary in my zone file, what do I have to do in the named.conf file? Is their more to this then I am thinking about?

Examples: zone file
NS1.mydomain.com
NS2.freeservice.com

Thanks

You will have to specifiy which zones will be transfered to your alternate DNS (within the named.boot) and if you are doing zone transfer security (recommended), you will have to allow that other DNS server access for zone transfers.

ie:

named.boot
secondary abc.com 10.10.10.10 db.abc.com

named.conf
zone "abc.com" IN {
type master;
file "db.abc.com";
allow-update { none; };
allow-transfer { 10.10.10.10 };
};

db.abc.com
; Add your secondary name server to the zone file and make sure that you reference the ip of the alternate DNS server in the reverse lookup file
