I am running on a Sun 3, using release 3.2 of Sun's operating system.
I am having trouble with running a program on one machine to write
to a display on the other. We have X version 10, release 4.
I do the following:
On one machine, I run xinit to create an X display and that
works fine. I can start xclocks, xterm windows, GNU emacs, etc.
Call this machine "mya"
On the other machine, call it "myb", I try to do the following
to run the clock remotely:
% setenv DISPLAY mya:0
% xclock
This dies with "XIO: Broken pipe"
Similarly, I try to use the call in a simple program of:
Display *disp;
disp = XOpenDisplay("mya:0");
...
and the program dies with the same error.
Has anyone been able to get programs on one Sun machine to
successfully use the display of another Sun machine. If so,
how is it done?

The list is in file `/etc/X?.hosts', where `?' is a digit representing the display number (usually zero, therefore). You can also temporarily add to this list using the `xhost' program. Without an entry `myb' in mya's /etc/X0.hosts file, you will get the error as reported. -- Bill UUCP: {seismo|ihnp4}!harvard!talcott!cfa!wyatt Wyatt ARPA: wyatt@cfa.harvard.edu (or) wyatt%cfa.UUCP@harvard.harvard.edu BITNET: wyatt@cfa2
