[BlueOnyx:15441] Re: Secondary dns problem on BO

[Janwillem Ronken]

Hi Michael,
Enabling logging does not show any entries (well, only 1 entry showing all
options set in /var/log/messages), nothing seems to happen.. Even when doing
a nslookup with the ns2 specified as server, no log entries.
But the result is validŠ so for now I will not be too worried, zone
transfers from ns1 (master) to ns2 and ns3 (slaves) seem to work, lookups
works..
Only that nasty error when checking my dns servers on dnscheck.iis.se where
ns2 complains that it does not answer queries over tcp and a DNS SERVFAIL
when quering for SOA.
I think I can live with it until migrating to 52xx :)

Thanks!
Jan



Hi Jan,

> * DNS SERVFAIL when querying x.x.x.x for SOA

On NS2 and in the GUI under "Network Services" / "DNS" turn on detailed
logging. It's an option at the bottom of one of the tabs. Then do a
"nslookup" again while you're watching the output of "tail -f
/var/log/messages". That should shed some light on the issue, as Bind
will then report a little more verbose about the nature of the problem.

A word of warning, though: Be really sure to turn the detailed logging
back off again when you're done. The amount of log entries it generates
is quite excessive. If enabled, Bind will log each and any query with
extended status information.
