DNS server syncing...

[Blaž Repas]

Thank you for your RE. I did the most easiest thing. I have put an 
include in bind.conf and put it in another folder, made the same 
arhitecture on my app server and configured app's bind to put new zones 
in this directory, then used rsync to sync this directory. Simple and it 
worked. I hope so. Because the app's DNS is just for creating zone 
records (with virtualmin) and it's not accessible from the internet.

thnx anyway. But i think i'll still use a system like you described on 
some other server.

cya!!
