Remote Desktop
If GeoDict is installed on a server that is shared by many users, a graphical remote desktop connection from your local computer to the remote server is needed to use GeoDict.
If both the local computer and the remote server use Microsoft Windows, Microsoft’s built-in Remote Desktop Connection tool can be used for this.
If it is a Linux server, we recommend to use TigerVNC. The graphical remote desktop connection with TigerVNC is a very convenient way to perform simulations on a remote Linux server.

Note! If multiple users use GeoDict at the same time, multiple GeoDict licenses are required. One GeoDict license can only be used in one TigerVNC session. If the same user starts multiple remote sessions (e.g., from different desktops) at the same time, multiple licenses are needed as well.

Follow these steps to use the remote desktop for GeoDict. Steps 1 to 3 are to set it up (administrator privileges required), and carried out only once. Steps 4 to 6 are done every time remote computations are performed:
1. Install TigerVNC server on the remote Linux computer
2. Install VirtualGL on the remote Linux computer
3. Install and set up TigerVNC viewer on the local Windows computer
4. Start TigerVNC server on the remote Linux computer
To start the VNC server, open a ssh connection to the remote Linux computer, for example with PuTTY.
Check if there is already a vncserver running with
tigervncserer -list
If no server is listed, start a new one with
tigervncserver
The server will ask you to set a password (if you start a TigerVNC server for the first time, otherwise the last password will be taken), then tell you the number you need to connect
New Xtigervnc server 'zyklop.kl.math2market.de:6 (becker)' on port 5906 for display :6
The session number (here: 6) is needed later.
If you have forgotten your password, you can set a new one with
tigervncpasswd
The ssh connection can be closed now.
This server stays open as long as you do not log-out the virtual session. A virtual session can be stopped using the -kill option and the session number (here :6) by entering
tigervncserver -kill :6

5. Connect the Windows computer to the remote Linux computer
As long as a virtual session exists (i.e. you have not logged-out or killed the session), you can connect to the remote Linux computer by starting a VNC Viewer and entering the hostname and session number:
A virtual desktop of the remote Linux computer opens:

6. Start and run GeoDict on the remote Linux computer
To start GeoDict, open a terminal and enter:
/opt/geodict2026/geodict2026
The started session on the remote Linux computer runs until you kill the VNC server. If you just close the remote desktop dialog box by clicking on the X in the upper right corner, the VNC server will keep running. Also, any GeoDict processes you started will continue to run in this case. You can also log out and shutdown your local desktop and the session will continue to run on the remote desktop. You can connect to the remote VNC server again later.
