UNIX platforms dsedit might not work if the display machine is set up to reject X-Windows connections from remote hosts. If this is the problem, you see a message similar to the following:
Unable to open X display. Check the value of your $DISPLAY variable. If it is set correctly, use the 'xhost +' command on the display machine to authorize use of the X display. If no X display is available, run dscp instead of dsedit.
This error may be caused by either of the following situations:
The value for the DISPLAY environment variable is not entered correctly or is not set.
Solution: Enter the DISPLAY environment variable correctly.
You are not authorized to open windows on the machine to which DISPLAY refers.
Solution: Run the command ‘xhost +’ on the display machine.
