X11 Forwarding


  1. Install an X Server on your Windows machine, we recommend VcXsrv.
  2. If using PuTTY, select 'Enable X11 forwarding' in Connection > SSH > X11. No further options should need to be modified. If using ConEmu, add -X to your ssh connection string while connecting to Klone.
  3. If it is working correctly, no error regarding XAuth should be received, and running the xeyes command on the Klone login node should spawn the eyes on your desktop.


  1. Install XQuartz as an X Server on your Mac either through a browser or brew install xquartz.
  2. Add the following to your SSH Config in ~/.ssh/config on your Mac:
    Host *
    XAuthLocation /opt/X11/bin/xauth
  3. Start XQuartz via the apps page or verify it running on the apps bar, feel free to close the terminal that pops up.
  4. Connect to klone.hyak.uw.edu ,including the -X flag in your connection string.


  1. Connect to klone.hyak.uw.edu with the -X flag included in the connection string. Make sure to test with xeyes to ensure functionality.
