Just a short comment. Linux/DECnet do not play right with RSX. The
development was all done against VMS, and it would appear to have lots
of bugs that were never ironed out. Success against anything except VMS
is dicey at best (unfortunately).
Wish I had heard that before we got rid of our RSX-11M-Plus system!
Why did you get rid of something so good? :-)
It's true our experience with DECnet/Linux is from VMS. For the last
decades we used the RSX system entirely from VMS using DECnet's
Task-to-Task feature to access custom UNIBUS hardware on a PDP-11/73
with a QNIVERTER.
Wow, that's a rather special setup. Nice to hear it worked well for you.
Do you know if a SIMH RSX system would be able duplicate the errors you
are talking about? Do you have any clue whether the problems are in the
Linux device driver or the applications? I know there are some
configuration hoops one has to jump through that seem to change with
every new Linux kernel. I did some hacking there to get it working.
But, I never had to hack the applications. That being said, the only
one we care about is DAP.
Feel free to drop me a note off-list if you think it is worth pursuing.
You should definitely see the same problem on an emulated system.
My memory might fail me, but in essence, I could sortof get DAP/NFT work
in one direction, but not at all in the other.
PHONE also did not work at all towards RSX. I don't think CTERM worked
either.
But easiest would be for you to just set up a system, and try various
things.
Exactly where the bugs are in the Linux code, I don't know. I never
digged much into this. At the time I was talking a lot with the main
developer of DECnet/Linux, but he/she never got around to look much at
it in the end. But the problems were known.
As for if it is worth trying to fix? I don't know. I don't need it
myself. There is TCP/IP, with both ftp and telnet on RSX, which I use
when/if I want to transfer files from something "odd" and RSX. :-)
