what is your OS?
I know, the code you wrote, gave me
Code:
xargs: arp: exited with status 255; aborting
: Unknown host

Then i change it, just to know if were arp's problem. but the problem it's at the time it is queried.. ( if it's queried :S ) the DNS maybe.. when it's executed the command..


My OS is:

Debian Lenny
Code:
Cypuysrv456:~# uname -a
Linux Cypuysrv456 2.6.26-1-686 #1 SMP Fri Mar 13 18:08:45 UTC 2009 i686 GNU/Linux
