Hello all
I'm seeking advice on what might have happened and what can be done in the
following situation. I noticed that 'ssh prima.eu.org' for me takes 0.2
sec, while 'ssh cvs.prima.eu.org' takes ~30 sec, while these two are the same
machine.
I suspected DNS misconfiguration, but didn't find any. Well at least
I didn't touch anything for months there. Anyway, the tcpdump output to the
closest resolver was:
17:10:10.601561 plab.ku.dk.2702 > danpost.uni-c.dk.domain: 40331+ AAAA? cvs.prima.eu.org. (34)
17:10:10.605903 danpost.uni-c.dk.domain > plab.ku.dk.2702: 56366 ServFail0/0/0 (48)
and so on with typical retranmission timeouts: 2, 5, 6, 3 seconds etc.
The AAAA intrigued me very much. I didn't find any mention to it in
RFC1035, but well it might be pretty valid; I just don't know.
Nevertheless, something is wrong, because /var/log/messages is thrashed by
Nov 8 15:02:11 plab named[228]: sysquery: no addrs found for root NS (AUTH210.NS.UU.NET)
Nov 8 15:02:11 plab named[228]: sysquery: no addrs found for root NS ()
Nov 8 15:02:11 plab named[228]: sysquery: no addrs found for root NS (AUTH210.NS.UU.NET)

Nov 8 15:02:15 plab named[228]: sysquery: no addrs found for root NS (hotel.ftf.net)
and the like.
Please help.
System is FreeBSD-4.3-STABLE, named-8.2.3
