Unexpected issues with "nslookup" command

[James Roberts-Thomson]

Hi Mark,

Thanks for your response; whilst I accept what your saying, I'm not convinced it applies in this case.

As far as I can tell, recursion is enabled on the servers.  (We don't have an allow-recursion entry in the named.conf, and my reading of the documentation implies recursion is enabled by default).  An "rndc status" shows "recursive clients: 0/0/1000", which suggests to me that I can have up to 1000 recursive clients simultaneously, and using the same configuration file on a test machine and turning up the debugging level gives "16-Apr-2010 15:34:37.026 client x.x.x.x#35622: recursion available"

Thanks,

James Roberts-Thomson

Stub resolvers really should be talking to nameservers that offer
recursion.  If it is talking to a nameserver that doesn't offer
recursion then some of the answers returned may be mis-interpreted
by the calling code.

The warning is telling you that you have a configuration error.
