Questions Addressed

You will need:

  • X11 or XQuartz (located in /Applications/Utilities/)
  • an account with IGPP (use this account request form to request a new account if necessary)
  • to be on UCSD network (if you are away from UCSD, login to VPN. Instructions on how to do this are located here: How to VPN into the UCSD network)


  1. Make sure that you are on UCSD network and have an AD account (required for SSH to Barnyard machines).
  2. Open a X11 or XQuartz window.
  3. SSH into the Barnyard machines by typing: ssh -X username@igppgateway
  4. Test display forwarding by typing xcalc. A window should appear with a scientific calculator.
