SSH

Once you are familiar with the Unix Command Line Interface, working on a remote computer is very easy.

Using SSH, you can connect to another computer, and use the cli as if you were working on that physical machine.

All you need is the computer's hostname (IP-address or hostname) and an account to login with.

ssh $username@$hostname

For example:

ssh john@applejack.science.ru.nl

The first time, you will be asked to accept the Security Certificate. Type yes and press Return to continue.

Then you can enter your password. A session is started on the other machine and off you go!
