To set up the terminal in X-Win32, follow these steps:

• Window's Start → X-Win32 2012 → X-Config
• Under the “Connections” tab, select “Wizard”
• Name: cluster ( or anything that you want ), Type: select “ssh”
• host: cluster.biac.duke.edu
• Login: your username, Password: (if you leave this blank, you will be prompted later)
• Command: click “Linux”
• Click “Finish”

If your new connection doesn't show up, Click “OK”, then re-open X-Config.

• Click your saved configuration, then “Launch”
• A terminal window should appear and you may be prompted to enter your password if you didn't originally save it.
• Also, if its your first connection, you'll be prompted to allow connections from cluster.

Once the terminal is usable, all graphical forwarding should work. Type, “nedit” on the command line to test.

The next time you want to connect, you can open X-Config and simply “Launch” your saved connection. If you drag the connection to the “Autostart” folder, it will open automatically when you open X-Win32.

To access the cluster from a Mac or Linux machine, open your terminal window (for Mac usually the program “terminal”, Centos is konsole or xterm) and run the following command

 ssh -Y username@cluster.biac.duke.edu

The -X parameter enables the forwarding of graphics.

• after major OSX updates sometimes it is required to re-install XQuartz and reboot
• if you're experiencing x-forwarding timeout failures its usually because SSH on OSX only forwards graphics for 10 minutes by default. You can change this behavior by setting a timeout in your local ssh config file ( ie: ~/.ssh/config )

Host * 
    ForwardX11 yes
    ForwardX11Timeout 596h
