Secondary Instructions for Launching a Session on Windows
- First, start Xming (which allows a graphical interface). It will appear as though nothing happened/opened, but it should be running. You can see if an X appears when you click the tiny up arrow at the bottom right of your screen.
- Next, you need to open PuTTY in order to connect.
- In the PuTTY configuration, enter the Host Name (for example: crcfe01.crc.nd.edu). You can choose to save this configuration for future connections (see below).
- Now we need to tell PuTTY to communicate with Xming. Do this by expanding the SSH menu in the left-hand column, click on X11, and check "Enable X11 forwarding."
- That's it. Now you can open your connection.
- HOW TO SAVE: Type Host Name, Enable X11 forwarding, give it a name in "Saved Sessions", click "Save". Done. In the future, you can simply click on your saved session, load it, then open it.
- It's important to remember to first open Xming, then PuTTY, then enable X11 forwarding. Happy connecting.
