Mathematica and MATLAB via X2Go

• Physics account
• either connection from the university network (wired or via Eduroam) or via university VPN
• Working SSH connection to entry

1. Open a terminal on your own PC
2. Change to the SSH directory with cd .ssh
3. If not already there, create a new SSH key for entry and authorise it on entry (e.g. with ssh-keygen -t ed25519 -f entry and then ssh-copy-id -i entry entry.physik.uni-bielefeld.de, using your physics account's data to log in)
4. If not yet available, create a new config file with touch config
5. Open the config file with a text editor of your choice (e.g. with nvim config)
6. Create the following entries in it, replacing alovelace with your own user name:

7. Save the file and close the terminal

This currently only works with the m2 server.

0. Prerequisite is that the SSH configuration has been adjusted as described above

1. Install the X2Go client according to the following instructions: Installing X2Go

2. Create a new meeting in X2Go(Create Session) with the following parameters:

3. Select "Single Application" as the session type and select the empty field in the drop-down menu on the right, then enter "mathematica" or "matlab" in the same field on the far right

4. In the Connection tab, set the Connection speed setting to "WAN" for VPN connections from outside the university network or to "LAN" for direct connections from within the university

5. The remaining settings can be left at the default values, see image:

6. Finally start the session and use Mathematica as usual. It may be necessary to close any sessions that are already open to connect.

7. After closing the program, you may be asked for a user name and password. This can be ignored.
