hi all,
I've notice that nslookup took a very short time befor output "no
answer from the server" and exit.
I used tcpdump to check what's going
on and I found that sometimes dns took more then a sec to respond, so I
tried to edit /etc/resolv.conf with some options (please see below) but
nothing heppen and morover, the nslookup doesn't respect the timeout
option nor the attemps option written in the file. 

alpine@alpibox ~> time nslookup some.host.local
Server:         x.x.x.1
Address:        x.x.x.1:53

*** Can't find some.host.local: No answer
