We are running X11 in two systems:
(1) Motorola Delta 3000
the X11 package: Graphic Service Extension XW82.14
operating system: System V/68 R3V5 (i.e. System V.3)
(2) AT&T 6386/25 WGS
the X11 package: Xwin Graphical Windowing System Release 3.0 Version 2.0
operating system: AT&T UNIX System V Release 4.0 (beta)
with a PC running a X terminal emulation package called XVIEW.
We have been running the following configuration successfully for over a year:
+-------------+ +------------------------------+
| Motorola | | 386SX PC clone/MS-DOS |
| System V/68 | |------------------------------|
|-------------| | XVIEW (X terminal emulation) |
| X11 (GSE) | |------------------------------|
|-------------| | PC/TCP (TCP/IP for MS-DOS) |
| TCP/IP | +------------------------------+
+-------------+ |
| |
... ---+---Ethernet------------------+--- ...
Recently, we acquired an AT&T 386 box and is running a beta version of
System V.4. We also have OpenLook and the above mentioned Xwin package.
OpenLook and xterm etc run fine winthin the AT&T system. However we did not
have much luck in trying to connect X clients/servers between the AT&T system
and the other two boxes (Motorola and the PC running XVIEW). I trapped
the ethernet data messages on the Motorola system and it seemed like the
AT&T system is using a different protocol:
- when the Motorola system tried to open a window on the AT&T system, it send
an TCP message with the proper destination
- when the AT&T system tried to open a window on the Motorola System, it send
an UDP message with FF's in the destination field
The message types are also different. Somehow, the conversation discontinued
after one or two more messages.
Anyone on the netland has any ideas?
Are there incompatibilities between different releases of X11?
Or did we missed something in configuring the system?
Is there any solutions?
BTW, ftp/telnet etc. work fine between the two systems. We have also
set up the xhost's as documented (BTW, I cannot find the X0.hosts file
in the AT&T system).
Thanks for any help in advance!
