# Prerequisites
UPPA reseachers, Master and PhD students can use the Pyrene cluster. Bachelor students cannot use Pyrene.
To access Pyrene:
1. An active UPPA account is needed. If not, submit a request on https://moncompte.univ-pau.fr.
1. Request access to the cluster is done via the [Helpdesk of the University](https://assistance.univ-pau.fr): *Recherche -> **Accès à un service numérique** -> check "Cluster"*.
# Command line mode (Windows, Linux, macOS): ssh
Open a terminal (on Windows, use the Terminal or PowerShell applications) and use one of the following commands:
```
# Without graphic redirection:
ssh username@pyrene.univ-pau.fr
# With graphic redirection:
ssh -Y username@pyrene.univ-pau.fr
```
where *username* is your UPPA login. Then enter your UPPA password.
# Graphical mode (Windows, Linux, macOS): X2Go
[Download and install the X2Go client](https://wiki.x2go.org/doku.php/doc:installation:x2goclient) for your OS.
## Configuring X2Go
This step is only needed once.
1. Open the X2Go Client.
1. In *Session -> New session*:
* Session: UPPA (or whatever name you want)
* Host: pyrene.univ-pau.fr
* Login: your_uppa_login
* SSH Port: 22
* Session type: XFCE
1. Click on OK

## Connect to the session
Once your session is configured, select it and enter your UPPA password.

![x2go_connect2](uploads/7189a0f0acdd826bf5dcd0cb6d3ff105/x2go_connect2.png)
You are now connected on your personal graphical desktop on Pyrene.
## Log out of your X2Go session
To log out, simply close the window of your X2Go session. Your open windows and applications will be kept until the next login.
## Kill a X2Go session
To kill a X2Go session:
1. Connect to Pyrene in [command line mode](#command-line-mode-linux-mac-ssh).
1. On Pyrene, use the following commands:
```
# Get the names NNNN of your current X2Go sessions:
x2golistsessions | cut -d '|' -f 2
# Kill the NNNN session:
x2goterminate-session NNNN
```
# From outside UPPA: VPN
Pyrene is not directly accessible from outside UPPA. In this case, you must use a VPN connection.
To connect to Pyrene from outside UPPA:
1. If you want to use the graphical mode, first [configure your X2Go session](#configuring-x2go).
1. Connect to the UPPA VPN network: follow instructions from https://moncompte.univ-pau.fr/mon_acces_vpn -> Configurer sa connexion VPN ("Configure VPN access").
1. Connect to Pyrene either in [command line mode](#command-line-mode-linux-mac-ssh) or in [graphical mode](#connect-to-the-session).
