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! -- Peter Yeung Amdahl Canada Ltd., Software Development Center 2000 Argentia Road, Plaza 2, Suite 300 Mississauga, Ont.
