I'm running a Bind9 (9.8.4-rpz2+rl005.12-P1) DNS on a Debian 7.9 server and all is working fine, but whenever I try to restart the named service I get the following error into syslog:
WARNING: key file (/etc/bind/rndc.key) exists, but using default configuration file (/etc/bind/rndc.conf)
named-checkconf command does not give me any error.
Since I don't want my DNS stop working prior to do anything I would like to have some tips from someone that knows better than me how can I get rid of this warning or if I should ignore this message.
