I am responsible for 2 nameservers... both are masters and authoritative for 400+ domains. They are sync'ed by rsync, so all changes are made to just one server. The load is increasing and I want to add a third server outside of the normal network, but set it up as a slave, rather than have 3 masters. Is it possible to configure the slave to transfer *all* zones from one of the masters? If so, how? I don't want to have to add each entry and define the 'master' in named.conf. I just want to start up BIND on the slave, and initially transfer all zones from one of the masters I define, then get updates as notifies are sent. This way when new zones are added on the master, a notify will be sent to the slave telling it about the new zone (plus any other changed zones) which will then retrieve the updates.

I am running a mix of BIND 8 and 9, btw.

(I've read up on how to set up slaves, etc. I think I have it all figured out. In fact, I have it working for individual zones. I just can't seem to figure out how to transfer all the zones from the master.

Thanks in advance...

AFAIK you will need to define a slave for each zone.
