X Window uses a client-server model, where an X server communicates with client applications such as the Fast Clone Console to provide graphical user interface display and I/O services.

Set up an X server on the workstation where you want to run the Fast Clone Console. To determine which X server your organization uses, contact your system administrator.

Also, configure the DISPLAY environment variable. This variable specifies the IP address of the system with the X server plus a display number. The default display number is 0. Use :0.0 if the X server runs on the local system. After the X server is running, it opens a TCP/IP listener port, usually port 6000.

If the Fast Clone Console client application is remote from the workstation where the X server runs, configure a DISPLAY environment variable on the client system that points to the X server on your workstation, where you want to display the Fast Clone Console.

The following table shows the commands to set the DISPLAY environment variable:

If you run Fast Clone gui.sh and get the following error message, the X Window environment is not properly configured:
