Connecting to the University VPN

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.

For additional help, refer to:

After connecting to the General VPN, you will then be able to connect via SSH or Citrix to our compute infrastructure.

Getting the FortiVPN client

The FortiClient VPN software can be downloaded for free from the FortiClient web site.

Once you have downloaded the client you will need to configure it.

Before you do that, you should test if you have VPN access. The best way to do this is to login to the VPN using your web browser:

https://gpvpn2.ucalgary.ca:10443/

If you can login there, you can then install the VPN client and configure it with following information:

  • Host: gpvpn2.ucalgary.ca
  • Port: 10443
  • User: your_uofc_user.name

If you cannot login, then you will have to raise a ticket with the help desk at

Connecting with SSH

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

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
