Connect via an X session (recommended)
========================================

This solution is based on the MobaXterm software, which provides several connection tools, including a SSH client based on Pu TTY, as well as an integrated minimalist X server, which allows the launch of graphical applications, such as astk or Salome-Meca.

The operating principle is as follows:


1. Connection VPN;


2. Connect to the cluster with a client SSH;


3. Launch graphical applications in the remote terminal displayed in the local X server.


Connection VPN
-------------

The user will start by establishing a VPN connection with the VPN network. This step is not described in this document.


Connect to the cluster in SSH
---------------------------


Launch MobaXterm and create a new session

In the MobaXterm home interface, click on "Session".

1. Click on "SSH";


2. Enter the cluster address, for example "aster5.hpc.edf.fr";


3. Enter the identifier (NNI or pseudo-NNI);


4. Click on "OK"


Password

Enter your password in the terminal, validate and click on "Yes" in the window that appears.


Launching graphical applications
-------------------------------------


MobaXterm interface
~~~~~~~~~~~~~~~~~~~~~~~~~

The MobaXterm interface is structured around two parts:


1. Remote files: allowing you to navigate in the remote $ HOME tree (you can choose to "synchronize" this view with the current shell directory by checking the box at the bottom left);


2. Remote shell: allowing commands to be entered into the remote terminal.


Launch of astk
~~~~~~~~~~~~~~~~~~

It is now possible to launch graphical applications like astk. For example on Aster5, enter "/home/rd-ap-simumeca/bin/astk" in the terminal.

Launch of Salome-Meca
~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can also launch Salome-Meca, for example on Aster with "/home/rd-ap-simumeca/salomemeca/appli/salome".

**Attention however:** in the current version of Salome-Meca (2017), the activation of graphic windows (OCC as VTK) causes MobaXterm to crash. You can therefore not use the Geometry, Mesh, ParaVis or even AsterStudy modules as they are.
