[HECnet] Attaching to hecnet

Yes, indeed. It wasn't even meant to work. Here's an excerpt from the DECnet (Phase IV) manual:

DECnet supports a variety of types of nodes developed during different phases
of DNA implementation. Phase II, III, and IV nodes and DECnet/OSI nodes
can all exist on a network. There are con   guration restrictions in such a mixed
network; one major restriction is that only nodes running adjacent phases can
communicate directly, as shown in the following list:
    Phase II   Phase II
    Phase II   Phase III
    Phase III   Phase III
    Phase III   Phase IV
    Phase IV   Phase IV
    Phase IV   DECnet/OSI
    DECnet/OSI   DECnet/OSI

Later there is mentioned that a Phase III node can exist in an Phase IV   area as an end node. It can communicate with a Phase V node through the Phase IV area.
I don't have personal experience with DECnet Phase III.


Regards,

Kari

What I meant with the phase III-IV-V answer is that direct connectivity

will work with a phase IV node in between. Functionality of course is
limited by the phase III host :-)
But you're absolutely right that very few people will have a phase III
system, RT-11 being the most likely candidate?

I've seen the bridge program, but am not sure how to make the .conf file
work. Is it possible to use DECnet address 1.1010 to try and make this work?

Hi.

DECnet phase IV nodes are backwards compatible with phase III.

Yes. But the question here was if phase V will interoperate with phase
III. I don't know the answer to that one, but on the other hand, I don't
think anyone around is running phase III anyway.

There are no restrictions in functionality between phase IV nodes and
phase
V as seen by the unpriviledged user. Area routing may be an issue on
Alpha,
and of course ncl is more of a pain to remember than ncp ;-)

True, as far as that goes.
However, I am not sure that a phase V node can operate as a phase IV
area router.

Someone else pointed out that although DEC claimed that alphas could not
be area routers, that information is incorrect, and you can just tell an
Alpha VMS phase IV node to be an area router, if you want to.

However, DECnet+ is phase V, and all bets are off. :-)

And yes, not only are the NCL commands more difficult to remember
(atleast for me), the node name management is way more difficult as
well. Do anyone know how you copy a nodename database from another
machine with DECnet+?

Two questions:
1-May I use area 44?

Sure.

2-Is there a short guide to set up DECnet over IP to connect to HECnet?

Not that I know of. Maybe Mark Wickens have something on hecnet.eu?
My page (http://www.update.uu.se/~bqt/hecnet.html) only have information
about the bridge.

DECnet-Plus isn't
able to connect, or at least reliably connect to all OS's that can
potentially be on HECnet. I forget what all OS's I was having issues
with, I know one was RSTS/E v10.1, but I want to say it also included
VAX/VMS. Once I *upgraded* my Alpha running OpenVMS to DECnet Phase IV,
all these issues went away. These were things as simple as SET HOST.

It's probably that DECnet-Plus (Phase V) cannot speak with DECnet Phase
III (such as on RSTS/E and TOPS-10/20). That's my guess anyway.

Phase V should be able to communicate with VAX/VMS since that's Phase
IV, which is the gold standard of DECnet, IMHO.
