Hi Rupert,

The mystery deepens since I looked at your configs and compared with
mine, and they are the same. The thing is, uh, when I run strace I see
the same thing happen. I can see a query going to my local name
server. 

I've never noticed this because (a) I don't use telnet and (b) my
nameserver responds quickly enough that I don't notice any wierd
delay. 

Now I'm really interested in the solution for your problem. Sorry I
can't give you a solution ;-)

Incidentally, ssh does not do this odd lookup and works exactly how
I'd have expected telnet to.

Cheers!
