Procedure Outline

Remote access to MOGON clusters is granted via Secure Shell (SSH) and confirmed with a second-factor of authentication.

Once your account is affiliated with an HPC project, you will receive a confirmation from us per e-mail, entailing further instructions on how to access MOGON. They sum up to the following to steps:

  1. Generate an SSH key pair and upload the public key to the JGU account website to facilitate an encrypted connection to MOGON.
  2. Prepare your smartphone for two-factor authentication (2FA) before contacting us to finish the time-based one-time password (TOTP) configuration.

These two steps are completely independent. While Step 2 requires face-to-face identification via video call, you can complete Step 1 on your own and repeat it as many times as you need, e.g. to generate key pairs not only for your workstation but also for your laptop.

Onboarding Check List:
  • Ask your PI to add your JGU account to an HPC project.
  • Generate your SSH keys using Windows or Linux/macOS .
  • Add your public SSH key to your JGU account as demonstrated here .
  • Prepare your smartphone for 2FA by installing freeOTP or privacyIDEA.
  • Send an to the HPC Group from your JGU account.
  • Complete the privacyIDEA configuration with an HPC admin.
