ss - an alternative to netstat

ss is used to dump socket statistics. It shows information similar to netstat. And It can display more TCP information than state than other tools .

As root, just issue:

#ss

This would you show you listening/established/past/ongoing connections with details such as IP address, sockets, protocol types, port numbers and some received/sent stats:

#ss -a

shows you more details.

#ss -h

helps you out ofcourse.
