Promoting secondary to primary DNS server

[sudhakar]

Hi all,
I'm a newbie to this list.
I'd appreicate if anyone of you gurus can point me to a link or resource
with the help of which I can promote a secondary DNS server to a Primary DNS
server.
I'm using BIND 8.2 on Linux 6.2.
I'd really be grateful for your comments and suggestions.

Thanks,

Sudhakar

If the zone is not Dynamically-Update-able, it should be as simple as changing
the zone definition and reloading (or "reconfig"ing followed by reloading that
particular zone).

If you have Dynamic Update for the zone, then you'll probably want to change
the MNAME field of the SOA record to reflect the new master. You can actually
update an SOA record through Dynamic Update, but it's a little tricky (from
nsupdate, you need to do an "add", and the serial number of the new record must
be higher than that of the old record, otherwise the update will be silently
ignored).

Hi Kevin,
Thanks a lot for the response.
My secondary DNS server is gets its dynamic updates from the primary, now I
want my secondary DNS server to act as the primary, I'd appreciate if you
can guide on this issue.

Thanks,

Sudhakar

Basically,

- Change the secondary's zone statement(s) from "type slave" to "type
master" and delete the "masters" substatement(s).
- Edit the zone(s) and change the contents of the SOA record(s)'s
MNAME field.
- Adjust other zone substatements as necessary (e.g., allow-transfer).
- Reconfigure other secondaries, as necessary (e.g., change the IP
address in their masters substatements).
- Reload all modified name servers.
