Description Matěj Cepl 2007-04-10 09:52:59 UTC 
Description of problem:
Using bind as a caching nameserver (without chroot) to connect to my ISP and to
RH's intranet (see attached named.conf). I played a little bit with opendns.com,
but now I have forwarders set only to the DNS server of my ISP provider
(ns.ph.ipex.cz).

Suddenly I begun to getting resolutions of everything to 1.0.0.0 -- couple of
times before I suspected some kind of misconfiguration and after couple of
restarts the problem went away. Today, it didn't so I switched off all
forwarding and run 'service named restart'. bind crashed I was able to make bind
working only when:

a) I set up forwarder again (this time just to my ISP DNS server, not OpenDNS)
b) I used 'service named stop; service named start' with 'service named restart'
bind constantly crashes.

Any questions?

Comment 3 Adam Tkac 2007-04-10 17:18:49 UTC 
Optional schema is this:

When you want use named like caching-only nameserver, please install
caching-nameserver package and work with /etc/named.caching-nameserver.conf &
/etc/named.rfc1912.zones configfiles. If you want use named like local
nameserver, please config your own zones and put your configuration to
/etc/named.conf (for example with system-config-bind utility). This always works
better than "wild" configurations which you write :). But this end of named
(sigsegv) is really bad, so let me check it.

Comment 4 Matěj Cepl 2007-04-11 14:34:19 UTC 
Just for the record -- I DID try system-config-bind and the results were exactly
the same as with my own named.conf (actually, the generated named.conf was the
same, so no surprise here).
Comment 5 Adam Tkac 2007-04-27 14:15:31 UTC 
Could be fixed in latest bind.
