remote login session to have that system use your local computer's X display? Assume that your local
computer is called me.luna.edu.
A. xdm me.luna.edu
B. ssh -X me.luna.edu
C. xhost +me.luna.edu
D. export DISPLAY=me.luna.edu:0
E. X me.lune.edu. - correct answersD. export DISPLAY=me.luna.edu:0
The DISPLAY environment variable controls what system programs attempt to use for their X displays.
Option D sets this variable to the first (:0) X server on me.luna.edu, as the question specifies. The xdm
program specified in option A is a GUI login program, but its use in this context is incorrect. The ssh
command in option B is a remote text-mode login program. Although it can tunnel X connections, its use
in option B will merely create a return text-based connection to your own computer. Option C tells the X
server on the remote system to accept connections from me.luna.edu. Option E launches an X server
with the parameter me.luna.edu, but this won't have the desired effect.
You've found the following three lines in your /etc/ntp.conf file. What do they mean?

uses the best time signal from these three servers.
