Connect to the W.M. Keck Cluster

Some things to know first:

Connect with SSH (command-line only)

From Windows

  • Download and install PuTTY. NOTE: PuTTY is installed on the Windows computers in the ETS labs.
  • Open PuTTY from the Start Menu.
  • In the box labled “Host Name (or IP address)”, type ens-hpc.engr.colostate.edu and click “Open” to connect.
  • Log in with your local compute cluster account.

From Linux or Mac OSX

    • Open a terminal window and type:
      ssh <your user name>@ens-hpc.engr.colostate.edu
    • Log in with your local compute cluster account password.

Connect with SSH (Graphical Forwarding)

Windows (method 1)

  • Download and install Xming
  • Download and install PuTTY
  • Start Xming (this will put a “X” icon in the taskbar).
  • Start PuTTY.
  • Under “Connection,” expand SSH and click on X11. Check “Enable X11 forwarding.”
     

  • In the box labled “Host Name (or IP address)”, type ens-hpc.engr.colostate.edu
  • Go to the section Session at the top left and under saved sessions, click on “Default Settings” and click save. This will save the setting for next time.
  • Click “Open” to connect
  • Log in with your Engineering user name and password.
  • Once you are connected, check that applications will open on your computer by typing xclock. This should display a small analog clock.

Linux

  • Open up a terminal window and type:
    ssh -XC <your user name>@ens-hpc.engr.colostate.edu
  • Log in with your Engineering user name and password.

Mac OS X

In order to run programs with X-forwarding on Macintosh OS X, you need SSH (which is installed by default) and X11 for Mac OS X, which is freely available.

  • Download and install Xquartz
  • Open a terminal window
  • At the prompt in the terminal window, connect to a compute server by typing:
    ssh -X <your user name>@ens-hpc.engr.colostate.edu
    or, if the -X gives you problems
    ssh -Y <your user name>@ens-hpc.engr.colostate.edu
    Note: The -X enables X-forwarding. Sometimes, you might need to use -Y instead, which enables trusted X-forwarding.
  • Run the application you wish to use from the command prompt.
