* log in to the remote host
* verify xclock works and s-c-securitylevel doesn't
* Run the following command and report its output:
(echo DISPLAY=$DISPLAY; echo XAUTHORITY=$XAUTHORITY; echo hostname=$(uname -n);
xauth -n list)
* While still logged on the remote host, run (su -) and check whether xclock
