Remote Desktop Simulation Method - Tutorial

1. Consult Mr A. Hume at the back of F211, School of Engineering and setup an account on the Solar computer.
Use University login information.

2. Confirm that VNC is running on the machine.

3. On the remote endpoint (for example, a computer off-campus) install the following two programs:

a) PuTTY, the SSH client.

Found at:

Ensure the correct installer is downloaded for the operating system in use.

If a red and white command prompt is visible, skip Step 12

12. To open a command prompt in UNIX, go to the PuTTY black session prompt and execute the following:

“setenv DISPLAY solar:1”

“/usr/openwin/bin/xterm &"
