Hi,

I have a similar setup working so I will explain how mine works, Then I
will try and explain how you should set up yours.

My situation: I have three *BSD boxes connected via Ethernet. Here is a
snippet from my /etc/hosts file:

  192.168.3.1 ratbert ratbert.giganet.net
  192.168.3.2 bullwinkle bullwinkle.giganet.net
  192.168.3.3 bob bob.giganet.net

Bullwinkle is my main X server. It happens to be a IIcx running NetBSD it
could just as easily be an X server runnign under NT or MacOS.  On
Bullwinkle, I have added the following to my ~/.xinitrc file:

  xhost + inet:ratbert
  xhost + inet:bob

This means, whenever I start my X server on Bullwinkle, I am going to
allow X clients from Ratbert and Bob to run on the *display* of
Bullwinkle. In my ~/.cshrc on both Bob and Ratbert, I have the following
line:

  setenv DISPLAY bullwinkle:0.0

Whenever I run an X client program on Ratbert or Bob, it is displayed on
Bullwinkle's monitor (my X server display).

Ratbert is a Centris 650 running NetBSD. Bob is an IBM Thinkpad running
FreeBSD. Note that X clients run on the *client* machine. Therefore, if I
am running a program on Bob (an i386 machine), I need to have the i386
version of that program running even though the *server* is mac68k. This
allows me to run the BSDI version of Netscape on the Thinkpad and still
display it on Bullwinkle.

Suggestion for running under MacOS or Windows 95/NT: You might want to try
MI/X. There are other X servers available such as eXodus, but MI/X is
*free*. I have used it under MacOS and it seemed to work OK. They have
both mac68k and ppc versions for MacoS users. The URL is:

I believe the SE/30 is weird in that it treats internal video as if it
were Nubus video. Also, just because you see the "ite at grf0 not
configured" message does *NOT* mean that X will not run. I get it at
boot-time but X still runs fine for me.
