Yes, that simulates the case where no name server is defined at all.
Sounds like a problem with your name server. It should pretty fast determine
that it cannot resolve the host and return with an error.
That would simulate the case where your dhcp server hands out invalid name
servers. Of course that will cause timeouts.

Ludwig - sure; pulling the plug makes the cable-sense shut down the interface
(typically) ;-)
Yes, that simulates the case where no name server is defined at all.
However - it is easy to reproduce the effect here: now, this is not what I do
-
my nameserver does in fact look up ~all internet addresses correctly [ but not
my localhost name for which it times out ]:
Sounds like a problem with your name server. It should pretty fast determine
that it cannot resolve the host and return with an error.
Anyhow edit:
/etc/resolv.conf to contain (only):
# www.ibm.com - ie. no DNS server there
nameserver 129.42.56.216
That would simulate the case where your dhcp server hands out invalid name
servers. Of course that will cause timeouts.
