How to setup secondary name server

[Me.B]

In some VPS providers, have a resource named "virtual private network". Isn't better use this network to transfer data from master to slave? I think that doesn't use bandwidth quota.

VPS private network is usually intra-machine, so not public & seen more secure. For BW counting you should ask your ISP but DNS sync would not use that much BW & don't forget it's done over SSH so it's "secure" (unless the NSA tap it ;-) ).

Here’s how we do DNS master slave auto replication… or better… slave —> master pull replication

Overview
...

This is brilliant. A dns replication option would be great... i was in the process of writing this when i found this forum entry.

Would this need any modification for zpanel 10.1.1?

I have already updated the the first script to use /etc/zpanel instead of /etc/sentora/.

for anyone using a non standard ssh port...

on my centos 6.5 i had to make one small change to make this work because i have ssh listening on a non-standard port.

in the named-fetch-slave-zones.sh i had to change
/usr/bin/rsync -e ssh root@MASTER-SERVER-IP:/root/named_slave_zones_transfer/named.conf.slave.zones .
to...
/usr/bin/rsync -e "ssh -p ####" root@MASTER-SERVER-IP:/root/named_slave_zones_transfer/named.conf.slave.zones .

Can this guide that Parknet create go to the wiki?

Know this could be a bit obvious, but why not ask your provider to give you a secondary ip address on the sentora machine? I find that most of the times DNS providers have to have 2 ip addresses this way you could use eg: ns1.sentoramachine.local and ns2.sentoramachine.local each of these A records would point to a different ip.
Rudimentary solution but it could be useful if you don't have the real need to set up another server to serve dns queries.

Just a thought....

It's flawed by design. As we use 2 different NS to avoid having a point of failure in this case a single dns backend. This is why I always advice to use cloudflare DNS or registrar DNS instead of building a setup on only one machine ( unless you have 2 different servers).

Guys, I keep getting this error while trying to sync my NS2. Followed the guide in this thread. Any ideas?
