[comp.sys.sun] VMS X Server / Sun X Client?

henryc@mcs213k.cs.umr.edu (Henry Clark) (03/14/90)

I have three machines set up like:

        -----------------------------------------------------------
                |                  |                    |
              -----              -----                -----
              | A |              | B |                | C |
              -----              -----                -----

where:	A: microvax running VMS
        B: microvax running Ultrix
        C: sun 4/110

I have some users which want to run a X application on (A) and display the
output on (C).  The problem is that (A) does DecNet and (C) does TCP/IP.
Although we currently use (B) to telnet between (A) and (C), is there
something we can run on (B) to turn X DecNet into X TCP/IP?
Alternatively, is there something I can run on (A) to make it produce
something (C) will understand or something I can run on (C) to make it
understand what (A) is producing? 

Please e-mail and if there's sufficient interest, I'll summarize back.

Yeah, this is a neat feature that DEC probably forgets to tell people - X
under VMS can only talk DECnet so it can only talk to other VMS machines.
I have also heard that Ultrix machines can be booted with their X servers
talking either DECnet or TCP/IP and that they can talk to VMS machines (or
their X servers can) if booted to DECnet. But, I think this is an either
or situation - if their X server is talking to DECnet it can no longer
talk to TCP/IP folks.  I've also heard that TCP/IP will be bundled into
the next release of VMS and that DECWindows/X 2.0 will talk to either
simultaneously. Actually, I highly doubt it will be bundled into VMS, I'm
sure DEC will charhe a bundle for it.

This info has been picked up from various trade rags, and my opinions of
DEC unfortunately do not reflect those of my company.
