Hello!
Once again I've been spending a lot of free time to consider an interesting
question. What can connect to our network, and what can't? Or for that
matter what shouldn't be connected at all.

Ditto here, although there are fewer nodes/areas online now than
previously. LEGATO continues to think that it can reach areas 52 and 59 via
A54RTR, although I don't believe any nodes are actually up in either area.
As far as I can see, LEGATO is probably correct in what it is thinking.
The GRE tunnels from A54RTR to area 59 are up.

Attempting to query some nodes in area 59 results in:
-SYSTEM-F-NOSUCHOBJ, network object is unknown at remote node
which sounds like a node that is reachable but doesn't have an NML listener.
If the node was not reachable the resulting error would likely be:
-SYSTEM-F-UNREACHABLE, remote node is not currently reachable

How does the Cisco DECnet decide what's up and what's down? It looks like
these Cisco boxes may think that areas are up and reachable even when
they're not.
I expect they behave the same as DECnet routers implemented by Dec.
I don't think they are reporting anything up that is is not really up.

Peter Coghlan.
Hi all:
My turn ... :)
Area: 33
Name: Fred Coffey
Location: Sandusky, Ohio (midwest, between Toledo and Cleveland)
Router: FRUGAL:: - connected via Multinet Tunnels to area 2 and 19
Cheers,
Fred
Everything looks ok from here now. I can reach area 7.

A54RTR is a Cisco IGS which has GRE tunnels to area 59 on test.
How does the Cisco DECnet decide what's up and what's down? It looks like
these Cisco boxes may think that areas are up and reachable even when
they're not.
The router(s) in area 52 and 59 don't appear to speak (much) NML either.
Probably more of the same Cisco boxes...

I'll start!
Various such lists have been started over time, but I don't think anybody
was willing to maintain them.
I agree that it's hard to figure out routing issues when the network
topology is unknown! A nice HECnet map would be worth its weight in gold
about now.
Area: 2

The Multinet license on SG1:: has expired. I tried to connect to
process.com to fix this but it keeps timing out. At the moment the only
thing running from this site is the bridge.
Stay tuned...

In the meantime, maybe we could ask members to check-in with their area,
name, and location. That would help me figure out what is going on at
this end. It may help others as well.
Area 54 is located in Dublin, Ireland. Router is CEIRE connected via Multinet
tunnel. A second (Cisco) router A54RTR is connected via GRE tunnels. No bridge
connections here.
Everything looks ok from here now. I can reach area 7. Earlier, area 7 appeared
in the list of known networks here but I could not reach it. It appeared to me
that only GORVAX was advertising that it knew how to reach area 7 directly,
which was odd for an area connected via the bridge.
Regards,
Peter Coghlan.
Ian,
I would run either RSX-11M-PLUS or RSTS/E. I am running RSTS/E on one
machine, and if I can ever recover my RSX kit I will be running M+ on
the other machine.

Area 42 is down at the moment - maybe up this weekend though
- I just acquired my first PDP11 so I'll be experimenting
with it this weekend (a long weekend in Canada).
Any suggestions on what to run on a PDP11/73?
Area 42 is in Kelowna, BC, Canada. The router is CANADA::

Johnny,
Please send out the latest copy of the AREA list to the
reflector. It
would be nice to know what is real about areas, locations,
and "owner".
I have currently area 7 and 8 disabled on my bridge, just
FYI. Seems
to have at least stabilized things on my side.
Routing loops are bad. However, DECnet should normally be able to
resolve this, and get things right, as from a topology
point of view,
DECnet can have multiple paths between nodes. Something is wrong,
indeed...
The current list of the areas are on MIM::, which is shut
down at the
moment, because of the issues with the computer hall. I
hope to have
the machine back up and running soon...
Since GORVAX have an alternative connection, I'll keep it
off at my
end for now, for trouble shooting. As things looks stable
right now,
it will be interesting to turn area 7 back on and see what
happens.
Hold on to your hats...
Johnny
