In Linux installations, we can install a software package, execute any arbitrary command, or even upgrade distribution on all client PCs.

We do the following:

* We start LServerAdmin application as an administrator. [c16]_
* We go to menu :menuselection:`LAN` and select a group of PCs or all PCs.
* We select :menuselection:`Remote Linux Commands` and then the type of command we want. (|image1|_)


Execute Command
---------------

* To execute a command to all Linux client PCs we select :menuselection:`Execute command`. (|image1|_)
* On the next dialog we type a console command that would be executed on all clients. (|image2|_)
* Next we select the client PCs running Linux. (|image3|_) 
* The screen divides on 2 sections so we can manage our running remote commands (see :ref:`Remote Command Execution Mode`)

Install Software
----------------

* To execute a command to all Linux client PCs we select :menuselection:`Install Software`. (|image1|_)
* On the next dialog we type any software packages we want to install, divided by space. (|image4|_)
* Next we select the client PCs running Linux. (|image3|_)
* The screen divides on 2 sections so we can manage our running remote commands (see :ref:`Remote Command Execution Mode`)


Distribution Upgrade 
--------------------

A very usefull feature of LServerAdmin is remote Distribution Upgrade on client PCs. This is something we would want to do on a regular basis.    

* To upgrade distribution on all Linux client PCs we select :menuselection:`Distribution upgrade`. (|image1|_)
* Next we select the client PCs running Linux. (|image3|_)
* The screen divides on 2 sections so we can manage our running remote commands (see :ref:`Remote Command Execution Mode`)

.. note:: The upgrading process is viewed as a nice progress dialog. However, if we want better handling of the upgrading using a terminal, we can use instead :menuselection:`Execute Command` feature with command : **apt-get update && apt-get dist-upgrade -y** 

.. change LServerAdmin to provide a menu to select gui or terminal upgrade
