I have an old linux machine on the network running Named 9.2.4. We have no documentation for this server or what has been configured. I need to migrate the DNS functionality of this server onto a new one but don't want to move all 30+ forward zones. Is it possible to enabled logging on the named service to log all DNS queries. I am pretty sure we will only be getting a few a day and after a month I will be able to see what DNS queries are active and what can be archived.
My current Named.conf.options file contains this section.

logging {
category lame-servers { null; };
category default { default_syslog; default_debug; };
category unmatched { null; };

Is this the correct file to change and what do I need to change to log the Source IP and the DNS name being quereied.
