I used "nc" for that, not "ping", because it do not interrupt is link
is down. If your goal is to discover if a host is up you can use that:

timeout=1; port=1
nc -zv -w $timeout $1 $port 2>&1
return $?

The "-w" command is the timeout (1 sec in this example).


I'd like to conclude with a positive statement, but I can't 
remember any. Would two negative ones do?       -- Woody Allen
