This procedure allows a terminal session on a Linux VM running on the Vaio laptop to access an X-windows application running on GRIDCTRL (192.168.1.252). This procedure can be expanded to connect to other machines.
GRIDCTRL (192.168.1.252) has been started in RUNLEVEL = 5 and has GNOME as the desktop.
The local VM has been started in RUNLEVEL = 5 and has GNOME as the desktop.
To allow the remote host (GRIDCTRL (192.168.1.252)) to send X commands to the X-server on the local system, enter the following commands in the root environment:
# xhost -
access control enabled, only authorized clients can connect
# xhost 192.168.1.252
192.168.1.252 being added to access control list
# xhost
access control enabled, only authorized clients can connect
INET:192.168.1.252 (no nameserver response within 5 seconds)

Use the following command to connect to the remote host (GRIDCTRL (192.168.1.252)) and allow X commands to be sent to the X-server on the local system:
$ ssh -X oracle@192.168.1.252
Verify that the DISPLAY environment variable is set correctly:
$ echo $DISPLAY
localhost:10.0
Run the canonical program to check that X commands are being sent correctly:
$ xclock &
