Need help getting Slave DNS Manager to work

[Chris1]

Hello,

I've got a Plesk 12 server with the "Slave DNS Manager" extension installed.

I've also got a CentOS 7 server that I would like to set up as a slave DNS server.

I've installed BIND on the slave server and opened ports 53 and 953.

I've followed the instructions on this page but I can't seem to get a link between the two servers:

I've also tried the config that the Plesk panel provides like the case in this thread, I get the same results:

Any help would be much appreciated.

I'm getting the following error on the slave DNS server:

Apr 26 00:49:37 ns.example.com named[3038]: invalid command from XXX.XX.XX.XXX#45617: expired

I'm getting this error in Plesk when I hover the mouse over the red exclamation mark:

Error code 1: rndc: connection to remote host closed
This may indicate that
* the remote server is using an older version of the command protocol
* this host is not authorized to connect
* the clocks are not synchronized, or
* the key is invalid

Could I please be advised what exactly I have to put in Plesk and what I need to put into named.conf?

I worked out the problem, it did end up being a clock sync issue. I installed and configured NTP on the slave DNS server and it is now connecting.

How can I read the DNS zones on the slave DNS server? When I try to read /var/named/domain.tld it says that it is a binary file and it isn't really readable.
