.. _Configure ssh server - Linux:

Linux Client - Configure ssh server
===================================

On each client running Linux, we login as the local user we have created during the installation. 

We do the following:

* :ref:`Start Terminal`
* :ref:`Activate root account - Ubuntu only` 
* :ref:`Install ssh server - Linux`

.. |image2| replace:: image 2
.. _image2: ../../../../_static/screenshots/local_network-unity-startterminal.png

We start the terminal as follows: 

* **Gnome** (*Ubuntu 10.04 - lucid, Debian squeeze*) : From gnome menus we start terminal by going to **Applications / Utilities / Terminal**. (|image1|_)
* **Unity** (*Ubuntu 12.04 - precise*) : From unity search bar we type **terminal** and press enter.(|image2|_) We can drag and drop the terminal icon to the left side bar, since we will be using it a lot.

.. _Activate root account - Ubuntu only:

(Ubuntu Only) - Activate root account
-------------------------------------

Ubuntu by default, uses **sudo** to execute commands with administrative priviledges and has **root** user account disabled.
  
We will enable **root** user account as follows:

From a terminal we execute

.. code-block:: bash

   sudo passwd

We type the password of the sudo user we are logged in, and then we type twice a new password for user **root**. [c1]_

.. note:: Password for the **root user** must be rather difficult for security reasons. If we have dual-boot clients with Windows and Linux OS, we select the same password for the **root user** to both Linux and Windows OS. We use the same root password on all client PCs.

.. _Install ssh server - Linux:

Linux - Install ssh server
--------------------------

To install **openssh server** we do the following:

From a terminal we login as root [c13]_ and execute

.. code-block:: bash

   apt-get update && apt-get install openssh-server
