Using SSH to connect to nodes
=============================

To SSH to the head node in a cluster, run::

  $ adam ssh -n [cluster-name]

EXAMPLE: To SSH to the head node in a cluster named "cluster":

.. code-block:: bash

   $ adam ssh -n cluster

   [root@192.168.1.1 ~]#

To connect to a specific node, include the node number after the 
cluster name. Node 0 is the head node, node 1 is the first 
compute node, and so on.

EXAMPLE: To SSH to the second compute node in a cluster 
named "cluster":

.. code-block:: bash

   $ adam ssh -n cluster 2
