Remote desktop access with NoMachine

On your RUG LWP desktop computer

NoMachine works via SSH. This means you need to make sure your account name (P-nummer) is listed in the file /etc/users_allowed_ssh. You can edit this file only when logged in using the physical keyboard of the computer. After at most 15 minutes access is enabled.

On your own computer or laptop computer

Download and install the NoMachine Enterprise Client for Windows, Linux or MacOS:
