.. code-block:: bash
ssh-keygen -t dsa
Do not create your new key par in the dufault directory (~/.ssh/). Use a temporary directory instead. So when you see this,
.. code-block:: bash
Generating public/private dsa key pair. Enter file in which to save the key (/root/.ssh/id_dsa):
enter a different filename. When the keygen asks for a pass phrase press ‘enter’ twice to create an empty phrase.
