Problem with named reverse forwarding zone

Hi all,

I’m very puzzled by this, I try to set up a zone in bind on Sles12.1 using yast to forward reverse lookup to a other server

I have set up like this in sles 12 named.conf
zone “10.in-addr.arpa” in {
forwarders { 10.1.1.13; 10.1.1.4; };
type forward;
};

the 10.1.1.13 and 10.1.1.4 has the zone 10.in-addr.arpa zone setup

If I do dig @10.1.1.13 -x 10.1.1.4

but if I do dig -x 10.1.1.4 I get this back

And if I do nslookup 10.1.1.4
I get this back

** server can’t find 4.1.1.10.in-addr.arpa: NXDOMAIN

This should be fairly simple but I can’t figure it out

Hi Lennart,

sorry for the late reply, I somehow missed this question.

/Lennart[/QUOTE]

the SOA reply may hint at a different, local zone declaration, making the local named believe that it’s authoritative, though that nslookup NX (“no such domain”) response counters that. What’s in the logs when you start the named process and have you already tried to turn on named debug?
