Connecting to the cluster

IUT users#

IUT users can use their academic VPN credentials (the same as for internet access) and follow the instructions below.

Do not have a VPN account?

IUT users who do not have VPN credentials can submit a request to the IUT IT-Center via the IUT Ticketing System.

OS: Windows, Mac, and Android#

Follow the IT-Center guide.

GNU/Linux#

On modern GNU/Linux distributions, no additional application installation is required. You can use the Network Manager to add and connect to the VPN. Follow the steps below (this example uses Ubuntu 26.04; steps may vary slightly across distributions):

  • Open the Activities overview and start typing Network.
  • Click on Network to open the panel.

linux-network-open

  • Click the + button next to the VPN section to add a new connection.

linux-network-window

  • Click on Import from file.

linux-network-import-from-file

  • Browse and select the OVPN file you have downloaded, then enter your username and password and click the Add button.

linux-network-vpn-profile

  • From the Network icon, connect to your VPN.

linux-network-vpn-connect

Non-IUT users#

The process is exactly the same as for IUT users, but you must use/import the ovpn file that was emailed to you. Your username and password are also provided in that same email.

OS: Windows, Mac, and Android#

Follow the same instructions as for IUT users.

Example: Connecting on Windows#

After downloading and running the OpenVPN Connect application, the following screen appears. Click on the "UPLOAD FILE" page, import the ovpn file, and create a new profile.

GNU/Linux#

Same instructions as for IUT users; see the example above.

Internet access after connecting to the VPN

For non-IUT users, local internet access is dropped after connecting to the VPN. To restore it, you can use the script provided at NHPCC VPN Connection Script repository.

Please note that you must first create the VPN connection using your Gnu/Linux network manager as explained above, then use this script according to its manual.

Logging in#

Now that you have successfully connected to the NHPCC network, you can connect to the cluster.

Use your favorite terminal client and SSH to our login server:

ssh myusername@login.hpc.iut.ac.ir

You can also connect to Panthera via the OnDemand web interface. For more information, please visit OnDemand Web Portal page.
