Zone transfers - Reverse zone won't transfer, forward is fine

[tjobrien21]

Hello,

I have a pair of DNS servers, one primary and one secondary. The main server resolves names fine, both forward and reverse. The secondary can only do forward, reverse doesn't work. Logs show success on forward zone, reverse shows this:

Dec 10 13:27:51 exmdnssec named[11623]: zone 26.3.in-addr-arpa/IN: refresh: non-authoritative answer from master 3.26.51.193#53 (source 0.0.0.0#0)

Here are relevant clips from what I believe to be the relevant files. Any assistance would be greatly appreciated - I can't seem to figure this one out. :-/

Again, any help would be greatly appreciated!

I suppose it seems silly to answer one's own question on the forum, but the problem has been solved and I'd rather nobody else waste time on it.

Answer: It's a simple typo in named.conf.

in-addr.arpa -vs- in-addr-arpa.

They don't match, so it didn't work.
