I tried everything related that I've found on these forums but worked. All my servers sending their zones to slave with 0 records inside them.
I have 3 servers having each one their bind (all running Debian) and another one acting as slave. I did exactly what the docs saying at http://www.virtualmin.com/documentation/dns/slave-configuration
What I want is server A,B,C to send their zones on server D(the slave). The slave (D) server logs showing:
Feb 23 19:49:42 euve19828 named: transfer of 'mydomain.com/IN' from my-IP#53: failed while receiving responses: REFUSED Feb 23 19:49:42 euve19828 named: transfer of 'mydomain.com/IN' from my-IP#53: Transfer completed: 0 messages, 0 records, 0 bytes, 0.001 secs (0 bytes/sec)
There is no firewall at all in any of the above mentioned servers.
Any idea how to troubleshoot this?
