[nsd-users] NSD Problems (Reverse Direction)

[Ken.Hendrickson at L3Harris.com]

What am I doing wrong???  I'm using nsd on OpenBSD.





nsd works only in the forward direction: from a name to an IP address.
I'm using my named zone files from way back.
nsd-checkzone says that the zone files are good.
Here are the startup logs for nsd:
----------------------------------------------------------------------
Jul  8 20:30:20 Soekris2 nsd[85856]: nsd starting (NSD 4.2.4)
Jul  8 20:30:21 Soekris2 nsd[78426]: zone 10.24.172.in-addr.arpa read with success
Jul  8 20:30:21 Soekris2 nsd[78426]: zone 20.24.172.in-addr.arpa read with success
Jul  8 20:30:21 Soekris2 nsd[78426]: zone 30.24.172.in-addr.arpa read with success
Jul  8 20:30:21 Soekris2 nsd[78426]: zone 2.168.192.in-addr.arpa read with success

Jul  8 20:30:21 Soekris2 nsd[78426]: nsd started (NSD 4.2.4), pid 71631
----------------------------------------------------------------------





nsd works in the forward direction (not shown).
nsd fails in the reverse direction:
----------------------------------------------------------------------
117 Soekris2# nslookup
> server 127.0.0.1 
Default server: 127.0.0.1
Address: 127.0.0.1#53
> set port 53053
> 172.24.20.1

** server can't find 1.20.24.172.in-addr.arpa: NXDOMAIN

Here is an example reverse-direction file: db.20.24.172.in-addr.arpa
----------------------------------------------------------------------

Any ideas?

Why would nsd work in the forward direction,
but not in the reverse direction,
if all of the zone files are good?

What is different between nsd and named?
