====== 📡 Remote desktop access ======

===== To a windows machine =====

The protocole used is RDP (Remote Desktop Protocole). It has to be enabled first on the remote machine.


==== From a windows machine ====

We use the build in windows application "Remote desktop" to connect to the remote machine. If you are connected through the IGE network, it easy: just but the correct credential.

If you are outside the IGE, it's a bit more tricky because you need first to setup a SSH tunnel and use it.

=== Setting up the SSH tunnel ===

Open Putty, then configure it as follows:

   * Session:
     * Hostname: ''ssh.ige-grenoble.fr''
     * Port: 22
     * Connexion type: ''ssh''
     * Give it a name and save it, for instance ''ssh_tunnel''

   * Connexion > SSH > Tunnel:
     * Source port: ''12345'' (can be almost everything, but remember it)
     * Destination: ''<ip of the machine>:3389'' The port 3389 is the default one use by RDP
     * Click ''Add''

   * Session:
     * Resave it :)
     * Click ''Open''
{{ :tools:remotedesktop4.png?nolink&400 |}}


It then ask for your credential to connect to the ''ssh.ige-grenoble.fr'' passerelle. It's your IntraGere login/password.

Once logged in, your SSH tunnel is up ! Do not closed the windows !

=== Setting up the remote access ===

  * Launch the ''Desktop remote access'' application.
  * Fill the ''computer'' to ''127.0.0.1:12345'' (i.e. localhost and whatever was your port in the previous part)
  * Click ''Connexion''

Tada! Now fill the correct credential to log on the machine.

==== From a linux machine ====

SSH is handle way more easily in linux... Also, the dedicated software for remote access is [[https://remmina.org/|Remmina]]. So first install remmina :

    sudo apt install remmina

Remmina support different protocols, including RDP to connect to a windows machine, but you may need to install it:

    sudo apt install remmina-plugin-rdp

Launch Remmina and create a new profile:
{{ :tools:remmina1.png?nolink&500 |}}

Enter the disired Name / Group and the correct IP address, User name, Password and Domain 
{{ :tools:remmina2.png?nolink&500 |}}

Go to the ''SSH tunnel'' tab, and click on

   * Enabled SSH tunnel
   * Custom: ssh.ige-grenoble.fr
   * Username: your IntraGere username
   * Select "Password" for the authentification (or set up your ssh profil)
{{ :tools:remmina3.png?nolink&500 |}}

Save it, then double click on the profile to open the connexion.
