Thank you for the clarification. If I add "nameserver 127.0.0.1" to the
VM (and comment out the existing name servers) and attempt to resolve a
DNS entry, the I see output similar to the following:
08-Apr-2011 22:51:50.116 network unreachable resolving
'www.redhat.com/A/IN': 2001:500:2f::f#53
08-Apr-2011 22:51:54.023 network unreachable resolving
'www.redhat.com/A/IN': 2001:503:c27::2:30#53
08-Apr-2011 22:51:54.024 network unreachable resolving './NS/IN':
2001:503:c27::2:30#53
I understand that this is because there is no upstream DNS for BIND as
configured in my named.conf. However, if I try to add a forward
forwarders {
192.168.239.2;
};
(where the host 192.168.239.2 is "upstream" DNS in my case), then DNS
queries are resolved by the client but do not appear to be cached, i.e.:
# rndc dumpdb
#
What am I missing ? Is it not possible to use a "forwarders" directive
in combination with a name caching server ?
Thanks,
Patrick
