You need to specify the "-l" switch as well, otherwise, netstat will only

"-a", which shows *all* sockets.

"ssh", since "-n" disables all name resolution.

This is very useful when DNS is down, as it often is if you are using
network trouble-shooting tools! Besides, all good admins know every IP
address they use by heart. Real men don't need DNS. ;-)
