To use compression add the -C flag:

.. code-block:: shell

	$ssh -C <username>@<host>

Using secure keys
'''''''''''''''''

To create keys to connect to your server in a more secure manner, first create the keys by executing:

.. code-block:: shell

	$ssh-keygen -t rsa
	
Add the key to a known location when prompted and enter a secure password.

Now you can copy your public key to the server that is going to receive the connection:

.. code-block:: shell

	$ssh-copy-id <username>@<host>

Now disable password login by editing /etc/ssh/sshd_config, the restart the sshd service.

.. warning::

    If you lose the key files you will be locked out of the target machine.
