Folks,
I googled PyDECnet but it came nothing as result. Where are PyDECnet and
DECnet for Linux (for current kernel version)?
Thanks,

PyDECnet is on svn://akdesign.dyndns.org/pydecnet/trunk/pydecnet. Documentation is in the
"doc" subdirectory.

I maintain a github repository of DECnet for Linux at:
<https://github.com/JohnForecast/RaspianDECnet
<https://github.com/JohnForecast/RaspianDECnet>>
It?s mostly targeted at the Raspberry Pi Raspbian release but I have tested (a slightly
earlier version)on Debian Buster x86 (both 32- and 64-bit).

I got 404 error on that link. It does not exist on Github.

Cool beans (Note, https://github.com/JohnForecast/RaspbianDECnet).? Two
quick questions:
1. I didn't see llogin (lat login) in the list of programs. Should I?
2. What operating systems have you tested against besides VMS?

No. LAT
wasn?t part of the DECnet kit that I started with.
What operating systems have you tested against besides
VMS?
RSX-11M+, Tops-10 and some Tops-20.

For anyone inclined to play with the latd implementation available for
Unix/Linux - beware. It has only been tested against VMS. It is
violating lat some way I have not had time to figure out, but it does
cause memory leaks if run against RSX, and I have also experienced get
very messed up when using llogin against a DECserver.
It sortof works, but is far from perfect.

I am very much inclined because it is very much annoying.? llogin does
work against Tops-20.? Almost.
llogin will sometimes work, often not, but almost always (and often)
fails without any sort of message whatsoever.? "Sort of" is very
generous, indeed, Johnny.? You're just silently put back into the
shell.? Unforgivable.
The only way to get to the bottom of it will be to attach a debugger and
see what's happening.

It is uneven. It seems to work better against some systems than others.
I guess that's what you get from reverse-engineering the protocol from a
specific implementation...

Not likely. For a while I entertained the idea of fixing that lat
implementation. But when I started digging around in the code I cam to
realize it's a total chaos, all written in C++.
So it would be better to just rewrite the thing from scratch, and in
some language with some sensibility still left in it.

I'll do one in Python at some point just for grins.

You're just silently put back into the shell. Unforgivable.

Unfortunately, at the time there was no known source for the LAT protocol
specification, hence the Linux support is the result of some serious reverse
engineering effort by Christine Caulfield.
Years later the specification surfaced on Bitsavers, thus the only piece
still missing is some brave soul willing to rewrite it from scratch :)

Another nice protocol worth some thought would be LAST/LAD...

Yes, I know that it had to be reverse engineered (another reason we
never adopted it); that wasn't my chief beef.
I just think failing with no message whatsoever is an incredibly rude
thing to do.
