PPA is set up with a master and slave DNS servers. DNS servers are hosted on an Amazon could services.

When DNS records are being added\changed in PPA, changes do no propagate to slave servers right away.

'/var/log/messages' on a slave server contains the alike errors:

May 24 06:04:24 ns2 named[25371]: zone refused notify from non-master:

Where is not a master DNS server IP address, though it is clear from '/var/log/messages' on master server, that notifies are being sent at the very same time.


Network communication between Amazon VM's is not transparent, so IP address is being replaced during network communication.


Please contact Amazon support in order to clarify the networking issue.

As a workaround, you may decrease the "Refresh" interval in the DNS resource activation parameters to make zone refreshes more frequent. In this case, slave server will be initiating the transfer on its own, and therefore, query will not be denied.

  1. Access "Resources" menu
  2. Find and select "DNS" resource
  3. In "Activation parameters" click "Edit", and lover the value of "Refresh field"

Value should be specified in seconds.
