“Small follow up of my former article on iproute2, in
this article we’ll see some use of the command ss to know more
information about Linux TCP / UDP Network and Socket Information
“ss command is included in iproute2 package and is the

“ss is used to dump socket statistics. It allows showing
information similar to netstat. It can display more TCP and state
