- I sent the following reply direct to Dan, but several other people seem to want
- something similar (or have missed the point). Note that the VT1200 only runs
- LAT or TCPIP and it is possible to have systems reachable by DECnet but not by
- either of the above protocols (e.g. via a DECrouter or an X25 link).
-
- BTW in another thread I noted that DECW$DWT_DECNET as supplied with
- DECwindows/XUI on a 5.5 system is linked against DECW$TRANSPORT_COMMON with a
- minor id of %x00000D, which is the Motif version. Fortunately, simply patching
- the EXE-header of DECW$DWT_DECNET to expect a minor id of %x00000C produces a
- working version.

- I too have a VT1200, although I use mine with both LAT and TCPIP. I have,
- however, encountered the same problem and solved it for DECwindows/XUI. I don't
- know if it works for Motif.
-
- DEC provide(d?) a program SYS$SYSTEM:DECW$DWT_DECNET.EXE which acts as an
- X-redirector for DECnet. Basically, you create a session on a VAX you can get
- to via LAT. Check that it has a valid display (SHOW DISPLAY) If you need to,
- you can create a display with a command like ...
-
- $ SET DISPLAY/CREATE/TRANSPORT=LAT/NODE=LAT_08002BABCDEF
-
- where the number is the ethernet address of the VT1200.. Next, create an
- authorization file called DECW$USER_DEFAULTS:DECW$DWT_DECNET_AUTHORIZE.DAT
- containing transport-node-name triplets (transport is *always* DECNET). E.g.
-
- decnet * dongray
- decnet cd3101 *
- decnet dusds1 genrad
- decnet dusds2 genrad
- decnet dusds3 genrad
-
- Then run SYS$SYSTEM:DECW$DWT_DECNET.EXE which will output a message indicating
- the 'server' it has created. E.g. I can get to CD4000 via LAT, so I get ...
-
- [Assigned DECnet server number 10 on node CD4000]
- [Remote display is server number 0 on node LAT_08002BABCDEF using LAT transport]
-
- The server number is 10 for the first, 11 for the second etc. But you only need
- one server for any number of remote sessions on any number of Vaxes (within
- reason!).
-
- Finally, you connect to the Vax you can only reach via DECnet and use
-
- $ SET DISPLAY/CREATE/TRANSPORT=DECNET/NODE=CD4000/SERVER=10
-
- replacing CD4000 and 10 with appropriate values. You now have valid 'display'
- on the DECnet-accessible Vax. All the DECwindows/XUI stuff works with this. I
- haven't tried Motif yet.
-
- Hope this helps.
