If you know which zone has changed, than you can do "rndc reload zonename".
If you don't, than "rndc reload" reloads all zones.
You could also try "rndc reconfig", but I think it will only load new zonesm the ones just added in configuration, not never wersions of old zones).

What I'm not sure is, given I have two hosts A and B, A is master, B is slave.
B fetches the zone files from A via rsync.
But, how B knows that the zone files have been changed and then run "rndc reload" to tell bind reload the zones?
Thanks & Happy New Year!

You need to create your own replication scripts as part of your dns management process. Simple Perl scripts even BASH works fine. But it may be a lot of work. And as it has been pointed out, you need to mesh with the great ISC/BIND software:

rndc

And I would go further pre processing everything using:

named-checkzone
named-checkconf

Just as some have mentioned, when you need to manage many NSs with views note that the perfect primary/secondary transfer system built in to BIND (that is really a great distributed responsibility solution and even a true DNS cornerstone) breaks. It breaks by adding complexity.

If a single entity is responsible for many DNS servers and zones and the entity has complete control over all the systems, then, I personally think that managed replication is much better.

See http://en.wikipedia.org/wiki/DNS_management_software for some free GPL systems that do work.

Disclosure: I wrote one of them.

Happy new years,
Cheers!
