Connection
==========

To connect to PSMN clusters, you will use :term:`SSH` [#ssh]_. The easiest way is with the following command:

.. code-block:: bash

    ssh mylogin@allo-psmn.ens-lyon.fr


With ``mylogin`` replaced by your login (as provided by PSMN). Then, from ``allo-psmn``, connect to one other login node (or compilation server, see :doc:`../clusters_usage/login_nodes`):

.. code-block:: bash

    ssh mylogin@c8220node1


.. NOTE::

    ``allo-psmn`` is a gateway server dedicated to connections, it only allows you to access and to transfer your files and **that's all**. Its only purpose is to connect to the PSMN's network to access login nodes.


See :doc:`../connection/index`  for more.
