ss – utility to investigate sockets.

Sometimes, you find some interesting application/command by accident, and that is just what happened a few days back. Well, I was doing a ssh and as usual made my share of mistake in typing and missed the “h” from the ssh command and saw a list of options instead of my prompt on remote server.

Now, that set me thinking and fond that its a very interesting command that comes with iproute on Fedoara, so if you want this command, then install iproute like this

1
 sudo yum install iproute

and then you can see the help with

1
man ss

 

By default, without any options you will see a list of all open sockets on your system.

There are a lot of options that you can use and couple of them are very interesting a useful.

-m — shows the memory

p — process associated with the socket.

-i — shows the TCP internal information

There are some other options which you might find useful.
