Setting up an SSH server on Ubuntu is about as simple as it gets. The  server of choice is OpenSSH.

Run this command from a terminal window:

sudo apt-get install ssh

To test that it’s working, you can try to ssh into your own machine:

> ssh localhost

The authenticity of host ‘localhost (127.0.0.1)’ can’t be  established.
RSA key fingerprint is  98:8a:b8:b2:9e:8a:84:e0:d4:08:27:fb:74:f0:de:d4.
Are you sure you  want to continue connecting (yes/no)?

Looks like it’s working! Naturally our ssh client doesn’t have the  key for the server, since we just installed it. You can type yes to  continue or just hit Ctrl-C to stop.
