Command-line control login remotely from another computer

Question

I need a way to get command-line control of a computer remotely, from another computer. That is, I need a secure way to log in from another machine on the network using a terminal.

Solution

You can use ssh. You'll need to install an ssh server on the remote machine:

sudo apt-get install openssh-server  

You can then connect to the computer with:

ssh username@remote-pcs-ip
