- When trying to connect from master (203.0.113.2) to slave (203.0.113.3) with the command below:
# rndc -b 203.0.113.2 -s 203.0.113.3 -p 953 -y "rndc-key" -c /usr/local/psa/var/modules/slave-dns-manager/slave_203.0.113.3.conf status
The following error appears in the /var/log/messages on a slave DNS server:
CONFIG_TEXT: ip-192.0.2.2 named[834]: rejected command channel message from 203.0.113.1#56373

DNS servers misconfiguration. Slave DNS server recognizes master as 203.0.113.1 instead of 203.0.113.2.
Resolution
- Connect to the server via SSH

CONFIG_TEXT: controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; 203.0.113.1; 203.0.113.2 } keys { "rndc-key"; };
};
