How to get an access
First of all, you need an account to access the platform. Please fill in the following form to ask for your account creation : CERSAT cloud account creation request
Note: we reserve ourselves the right to grant or refuse the access to our processing resources, depending on the processing platform load and priorities. The description of your project will help us to set these access priorities in case we face with too many demands.

Connecting to Nephelae
To use Nephelae, each user has to connect to an entry-point virtual machine (shared or user-specific), which is directly connected to the Cersat Cloud infrastructure.
SSH Client is required since SSH Protocol is the standard way to access the entry-point.
Depending on your constraints, the way you access to the Cersat Cloud Facility may vary, here is the matrix summary:
|connexion from||access type||requirements||notes|
|internet||Virtual Private Network ("VPN IFREMER")||IFREMER extranet & intranet account||
NetworkConnect (https://domicile.ifremer.fr/nc), a service provided by Ifremer IT department, is the recommended way to connect to IFREMER infrastructure from internet (easy from an up-to-date Windows desktop with antivirus and recent Java JRE version; painful from Linux)
Remote Graphical Desktop with NxNomachine is OK
|SSH Tunneling & Hop ("Vbannec IFREMER")||IFREMER extranet & intranet account||
Once connected to the web IFREMER "domicile" portal (https://domicile.ifremer.fr/) and the Java tunneling applet started, user can connect to the "vbannec" host gateway. The , just ssh again to your Cersat Cloud entry-point
Remote Graphical Desktop with NxNomachine is NOT OK
|SSH (direct connection)||IFREMER intranet account
user fixed IP adress
|Easiest way to use the Cersat Cloud from internet, but requires a specific authorization
IFREMER network ("intranet")
|IFREMER intranet account||SSH (direct connection)||IFREMER intranet account||Remote Graphical Desktop with NxNomachine is OK|
Tools you can use to connect
This list is not comprehensive, but summarizes the usual tools. They all rely on SSH protocol.
Note:. we strongly encourage to use the "nxclient" tool to connect to the Cersat Cloud infrastructure, since it provides an efficient remote graphical desktop (with session resuming when disconnect).
Command line tools:
- from Window : putty
- from Linux : ssh client, sftp, scp...
Remote graphical desktop tools:
- NxNoMachine for Windows, Linux, Mac
- WinSCP for Windows
- Putty : http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe
- Nx/NoMachine : http://www.nomachine.com/download.php
- WinSCP : http://winscp.net
