sudo
----
The ``ansible`` user can run every command as root without password. You can also switch user to ``root``.

.. code-block:: bash

    # switch to root user
    sudo su - root


ssh setup
---------
On all servers are ssh keys deployed for the ``ansible`` and ``root`` user. So you can connect between your servers without a password.

.. code-block:: bash

    # connect from srv to web1
    ssh web1.<name>.lab


.. important::

    Please be aware, that ssh host key checking is enabled. So you have to accept the key exchange.


Connect to your server
----------------------
For both users is the password **login**.

.. code-block:: bash

    # connect to your server as root user
    ssh -l root srv.<name>.lab

    # connect to your server as ansible user
    ssh -l ansible srv.<name>.lab
