[Pdns-users] PDNS Reverse DNS lookup recursion

[GordonJB]

Hi all,

I have a PDNS server set up with a zone and reverse zone for our domain
(here 1.2.3.4), and have the recursor configured to forward requests not in
our recognized zones to another DNS server on the network (here 1.2.0.4).
While this works fine for hostname lookups, it doesn't seem to work for
reverse DNS. If I dig an IP that is in PDNS' reverse zone, that works fine,
but any other IP's fail outright.

and syslog shows 

Nov  6 06:49:25 example-dns pdns_recursor[28151]: Failed to update .
records, RCODE=2

It seems PDNS is onl looking at the authoritative zone, how can I get these
to resolve with the recursor that is configured? My versions are server 3.1
and recursor 3.3. Config files are:

pdns.conf:
allow-recursion=10.0.0.0/8,192.168.0.0/16
allow-recursion-override=off
daemon=yes
disable-axfr=yes
guardian=yes
launch=gmysql
lazy-recursion=yes
local-address=1.2.3.4
local-port=53
recursor=1.2.0.4

recursor.conf:
forward-zones= example.local=1.2.3.4, other.net=1.2.0.4,
3.2.1.in-addr.arpa=1.2.3.4
local-address=127.0.0.1
local-port=53

Many thanks,
Gordon
