This page contains information on how to access the UBELIX cluster via SSH (Secure Shell).

Log in to UBELIX

Before proceeding make sure that:

  • you have your Campus Account activated for UBELIX (see above)
  • you have a working SSH client
    • Linux/Mac: e.g ssh command in a terminal
    • Microsoft Windows: MobaXterm or Windows Subsytem Linux.
  • you have familiarized yourself with basic Unix-based terminal commands.


Login to UBELIX is only possible from within the UniBE network. If you want to connect from outside, you must first establish a VPN connection. For VPN profiles and instructions see the official tutorial.

Login nodes

There are four login nodes in UBELIX:


To access UBELIX, you can choose any one. If the load on a login node is high, you can log out and pick another one.


Run the following commands in a terminal. Open an SSH connection to :

$ ssh <user>
At the password prompt enter your Campus Account password:

$ ssh <user>

Usually there is no indication of typing when entering your password (not even asterisks or bullets). That’s intended. Just enter your password and press ‘enter’.

After log in successfully you will see the welcome message and the command prompt:

  • In the “Advanced SSH settings”

    • Set SSH-browser type to ‘SCP (enhanced speed)’
    • Optionally, tick the ‘Follow SSH path’ button MobaXterm Config
  • From now one the settings are stored and you can access the session on the left at the star icon MobaXterm Sessions
