We often have to generate an X-window display on one computer and display it on another one. The permissions and flags that have to be set for this to happen are different on the Vax and Unix systems.
If the Display Server is a Unix based,
xhost + morgan01.slac.stanford.edu will let the
to put up windows. Replace the "+" with a "-" to
undo access. Changes are in effect for this one session only, i.e.
you need to issue the command again the next time.
If the Display Server is Vax based, do the following.
Options -> Security....
Enter the node name, e.g.
whose displays you will accept. Set Username to *, and
tcpip. See the example below.
OK to get out.
To make these changes your default for
future sessions, select
Options -> Save Session Manager.
xhost +command on a Unix Server. This will allow everyone to send displays to your window -- generally considered to be a bad idea.
If both the Client and the Server are Vax based, you could substitute
tcpip. This is very unlikely to be the
case for us.
