= Access to the computer ressources of LEGI =

== computer account ==
All members of LEGI, including visitors, receive a computer login and password, common to all the computers belonging to the network at LEGI. This gives access to the [http://intranet.legi.grenoble-inp.fr/?lang=en intranet of LEGI] (in French), which contains a [http://servcode.legi.grenoble-inp.fr/projects/sysadmin-about wiki] about computer ressource. Useful sections:
 * [https://www.legi.grenoble-inp.fr/webmail  Access to webmail]
 * [http://intranet.legi.grenoble-inp.fr/spip.php?rubrique22 Access to bibliography]
 * [http://servcode.legi.grenoble-inp.fr/projects/sysadmin-about/wiki/HowTo/Calcul Acess to the computing ressources]

To enable connection of your own laptop to the network, please contact the computer support service of LEGI. 

To reach the computer server 'servcalcul3' from a Linux machine at LEGI, use the command 'ssh -CX servcalcul3' (the option '-CX' gives access to a graphic terminal).

For remote access with graphic interface, you can use the terminal system NXclient, available for all the classical operating systems (Linux, Widows, MacOS). This can be used also for remote access from outside using any decent internet connexion. 

== Terminal NX client ==
NXclient can be directly downloaded from http://www.nomachine.com/download.php. 

To configure the connection:
 * host: servcalcul3.legi.grenoble-inp.fr
 * key: you need to upload a key ('certificat') text file
 * 'Enable SSL for all traffic' (default), do not 'connect through http proxy' 
 * different user interfaces can be chosen. The interface 'KDE' is fairly similar to Windows system.
 * graphical options: for a fast response select
   * disable !DirectDraw
   * disable deferred screen update
   * disable ZLIB stream compression
 * keyboard: pour un clavier francais, utiliser le menu 'Advanced/Keyboard/French(Alternative)' ET si vous avez toujours des problemes sous KDE : 
   * tapez la commande setxkbmap fr
   * dans le menu "Control Center" puis "Regional & Accessibility" puis Keyboard Layout choisissez Model 105 Keys et layout France,
     vous devriez avoir un petit drapeau dans la barre de menu en bas a droite pour selectionner votre clavier francais.
   
== Acces to data ==
Data transfer from/to outside cannot be done by NXclient (except as attached files using webmail). For that you need scp procedure, using par example [http://sourceforge.net/project/showfiles.php?group_id=21558) filezilla]. Configuration of filezilla:
 * host: servcalcul3.legi.grenoble-inp.fr
 * type of server : SFTP
 * account : normal
 * user name, etc

== Data organisation ==


Une baie de 10TB utile est connectée sous /coriolis/bigone/PROJETS

Les disques partagés des autres PC sont dans /coriolis ; me demander pour ajouter un partage particulier.

== Matlab ==
Open matlab by typing 'matlab' from a terminal, or 'matlab &' to keep the terminal active for new commands. Choose as 'Current Folder' the folder which contains your processing functions (an alternative option is to declare paths to your functions, but the configuration cannot be saved for next opening of matlab). 
executer matlab depuis un terminal, ou en entrant matlab dans le champ s'affichant apres avoir pressé les touches Alt+F2

Par defaut, matlab est lancé avec une priorité basse de 10 afin de ne pas perdre de reactivité du système lors de l'execution de longues routines de matlab.

Matlab est installé, le fichier contenant les paths n'est pas modifiable , si vous desirez ajouter vos propres repertoires il faut creer votre propre  A COMPLETER
