Turning on bind query logging

If you want to turn on the query logging for bind, you can use the rndc command.

$ rndc querylog

To see whether your querylog is on or off, use this below command:

$ rndc status
or
$ /etc/init.d/named status

After running the above command, you can see these lines:

[root@secondary-dns ~]# rndc status

soa queries in progress: 0
