I am having difficulties forwarding X11 on my Vaxstation 4000-90 running OPENVMS 7.3. I have the display correctly configured, and I have allowed the
VAX's host name using xhost on the remote machine. create/terminal results in
the following:

%DECW-E-CANT_OPEN_DISPL, Can't open display.

Multinet /X11debug reports:

%X11DEBUG-I-STARTING, MultiNet X11 transport diagnostics starting...
%X11DEBUG-S-PASSEDALL, passed all X11 tests

However, the SYS$MANAGER:DECW$SERVER_0_ERROR.LOG notes that

DECW$TRANSPORT_COMMON image base address: 00001200
DECW$TRANSPORT_DECNET image base address: 00887600
%DECW-I-ATTACHED, transport DECNET attached to its network
DECW$TRANSPORT_LOCAL image base address: 00892800
DECW$TRANSPORT_TCPIP image base address: 00894A00
%DECW-W-ATT_FAIL, failed to attach transport TCPIP
-SYSTEM-F-NOLOGNAM, no logical name match

Wireshark also reports no activity from the VAX using any X11 based protocol
with the exception of XDM, which establishes a session, but does nothing.
(Which makes sense, considering that multinet probably contains the
connection side, and gets everything else from DECWINDOWS)

Now, this machine previously had UCX installed on it, which I uninstalled
because I can never manage to get it to work correctly with regards to DNS
resolution. My best guess is that there is some esoteric configuration file
that still has the UCX values that is screwing up X11. Is there a way to get
a more verbose output, and actually find the logical that's causing it to
choke? Other then that, where would the most likely trouble spots be?

Sounds like a problem. Have you looked at the MultiNet
docs to see if "TCPIP" is the right thing to add to
DECW$SERVER_TRANSPORTS, or if there are other necessary steps
to make it work as an X transport?

If you don't have a working IP X transport, then a lack of
IP X traffic would not amaze me.

I've never had any such trouble, but with that problem
description and my weak psychic powers, I can't suggest much.

Wouldn't be my guess. Some actual MultiNet expert/user
(or a manual) might have more info than I.

set display/crea /node=(laptop's IP address) /trans=tcpip

Show DISP shows:

Device: WSA10: [super]
Node: 192.168.2.6
Transport: TCPIP
Server: 0
Screen: 0

The command for the transport is the same for both UCX and Multinet. I've had
this work in the past before I reinstalled the operating system on this machine
(The hard drive was wiped due to operator error) . This was the reason that I
was suspicious of UCX, I'd never /actually/ uninstalled UCX from the machine
before. I'd just let it sit dormant. The only other difference that I can think
of is that this machine isn't patched. (The installation was after the end of
patch availability, and I'm not sure how many of the patches I actually have on
this machine.) There was a past post on vmsnet.networks.tcp-ip.multinet about
a similar problem, involving patches, but it appeared that the patches were to
Multinet, (To quote Geoff Bryant from process)

Since process was releasing the eco, one would assume the problem to be with Multinet, and since the version in question in that post was v4.3a, it's unlikely to be the same problem.

(Actually, rereading that post reminded me of something. There are two
differences between my current set up and past set ups. Multinet 5.4 was newly
released, thus I've never actually had it work before, in the past I was using
5.3. This may be the actually problem)

Assuming the laptop is at 192.168.2.6, that look's good.

I think I recall a problem in the past with Multinet's X11 TCPIP
transport image not being automagically installed into the correct
directory.

UPDATE:
I've found a multinet 5.3 kit on a simh vax. Is it worth a try to install 5.3,
and see if that would work?

The laptop is 192.168.2.6. I guess I'll try and comb through comp.os.vms and
see if I can the problem you mentioned. Was this something new with multinet
5.4?

an artifact of show/network not being updated by DHCP, but the ip address
shown by MULTINET configure/menu is as the value in the form for the
interface is 0.0.0.0, with DHCP enabled. NFS, and telnet work, so I'm not sure
if this is a red herring.

I don't recall this being specific to any version, I just seem to
recall having to manually copy the file. Memory is vague, though, it
could have been the mail transport instead of X11.

Yes, this seems to be the problem. Start_multinet.com, contains the following
entries:

$ !
$ ! Install X11 transport
$ !


If F$Search("SYS$SHARE:DECW$TRANSPORT_MULTINET.EXE") .Nes. "" Then -
Install Add SYS$SHARE:DECW$TRANSPORT_MULTINET/Open/Share/Header/Protect


I think (I really don't know that much dcl) that the purpose of this is to
install SYS$SHARE:DECW$TRANSPORT_MULTINET.EXE (if it exists). My computer
does not have this file, and I couldn't find any file matching the pattern
*transport*.* (or *DECW*.*) in any of the files in the multinet kit. Do you
know where the file might be?

I got the same problem. The solution I found was to enable and start XDM (X Display Manager) from the config of TCPIP.
@TCPIP$CONFIG
select server config
select XDM
select ENABLE and Start on this node.
exit
It then worked for me.

Look into SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM and search for the
decw$server_transports symbol definition. It probably includes "TCPIP".

There may be multiple definitions of this symbol - check which one is
used for your paricular VAX and remove the TCPIP transport from this
definition.

Then restart your DECwindows server and you should be all set.

Hope this helps,
Hans.
