RCS maintains and operates various systems and clusters which can be connected to from within the University of Calgary campus network or via the University of Calgary IT General VPN.

Connecting with SSH

Secure Shell (SSH) is an encrypted network protocol that allows secure communication between your computer and a server.

All connections made to our infrastructure must be made from the University of Calgary campus network or via the University of Calgary IT General VPN. Please refer to the General VPN Knowledgebase Article for help on setting up your General VPN connection.

On Linux or MacOS computers, SSH is most likely installed and can be used by opening a terminal and running: 

ssh username@arc.ucalgary.ca

For work requiring X11 forwarding, pass in the -X flag. 

ssh -X username@arc.ucalgary.ca

On Windows, there are various clients that can be used to connect to our cluster including:

  • PuTTY
  • MobaXterm
