many systems you can
        disable the MOTD on the remote server by creating a zero-length file
        called :file:`~/.hushlogin` on the remote server. If a prompt cannot be found
        then this will not necessarily cause the login to fail. In the case of
        a timeout when looking for the prompt we assume that the original
        prompt was so weird that we could not match it, so we use a few tricks
        to guess when we have reached the prompt. Then we hope for the best and
        blindly try to reset the prompt to something more unique. If that fails
        then login() raises an :class:`ExceptionPxssh` exception.

        In some situations it is not possible or desirable to reset the
        original prompt. In this case, pass ``auto_prompt_reset=False`` to
        inhibit setting the prompt to the UNIQUE_PROMPT. Remember that pxssh
        uses a unique prompt in the :meth:`prompt` method. If the original prompt is
        not reset then this will disable the :meth:`prompt` method unless you
        manually set the :attr:`PROMPT` attribute.
        
        Set ``password_regex`` if there is a MOTD message with `password` in it.
        Changing this is like playing in traffic, don't (p)expect it to match straight
        away.
        
        If you require to connect to another SSH server from the your original SSH
        connection set ``spawn_local_ssh`` to `False` and this will use your current
        session to do so. Setting this option to `False` and not having an active session
        will trigger an error.
        
        Set ``ssh_key`` to a file path to an SSH private key to use that SSH key
        for the session authentication.
        Set ``ssh_key`` to `True` to force passing the current SSH authentication socket
        to the desired ``hostname``.
        
        Set ``ssh_config`` to a file path string of an SSH client config file to pass that
        file to the client to handle itself. You may set any options you wish in here, however
        doing so will require you to post extra information that you may not want to if you
        run into issues.
