Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I'm trying to migrate a dns server that has several thousand zones loaded on it. The named.conf file has about 17 different includes, and some of those files also has includes in them, and lots of commented out etc. It's a fricking mess!

I'm wanting to get a list of all the zones currently loaded into BIND. I looked at rndc dumpdb but it doesn't show me just the zones.

Instead of following the messy include files, is there an easier way to get a list of the authorative zones inside BIND? Thanks!

You can run rndc dumpdb -zones to create a file called cache_dump.db. This file will contain all authoritative zones and will be created in BIND's data directory.

Thats what i thought too but its only showing me the reverse dns arpa zones –  DuPie Jun 21 '12 at 18:22
I would check the log files for more information. If only the reverse ARPA zones are in the dump file, I would say that only these are loaded in the DNS server. –  Vladimir Blaskov Jun 21 '12 at 18:25

Confirmed rndc dumpdb is the best method.

In my case, i discovered that there was 2 seperate bind instances running on the same server (don't ask), one doing forward dns and one doing reverse dns. Without specifying the PID, it attached to the one only doing reverse dns and only showed me that.
