The answers to those questions are 'it might', 'that depends' and 'because it
mightn't' respectively. :)
Have you tried those alternatives from the same IP address as you are using
for your Linux machine ?
I'm not as convinced now that nslookup does use tcp. I don't have a copy
on this machine, only 'host' and it uses UDP so I haven't been able to double
check.
Your strace suggests that the query was sent and nothing received before it
timed out. I see nothing to suggest that there is a problem with your linux
machine at all.
The send looks ok, you just get no response before the select() times out.
I'd be looking further afield.
