Onderwerp: [HECnet] Router for area 1

It bugs me, although I can't point at an actual problem that it causes,
that the routing node for area 1 is seen as CTAKAH, rather than MIM. Since
CTAKAH is not actually local to Uppsula (I think that's where MIM is) but is
rather at the other end of yet another bridge, this means that any traffic
for area one, no matter what its ultimate destination, has to make an extra
round trip to Russia.
This happens because when there are multiple routing nodes for the same
area, DECnet uses the one with the highest address. The obvious solution
would be for Johnny to renumber MIM as, say, 1.1023.

Or make CTAKAH a circuit router since that is all it really does.
The "loops" in the Hecnet topology ought to be avoided but running area
routers where a circuit router would suffice is second on my list of
things I'd prefer to avoid.

Paul,
Sorry for the ignorance, but what is DAP?

Subject: [HECnet] Printing across HECnet
Hi guys,
Just wondering whether there is a 'standard' mechanism for queueing print jobs across DECnet areas (for example from an arbitrary node to SLAVE via HECnet)?
I've acquired a PSI PP404 high speed wide carriage printer as well as a large quantity of 11x14 paper, so was wondering if there would be any interest in an 'occasional' printing service for the cost of postage for those who either don't have a printer connected to their DEC machines or more likely who'd like wide continuous listings.

What is the INFO.TXT you guys are talking about? Should I have one on STAR69 with my node list in?
Mark,
The HECNET INFO.TXT files is located in the default directory for the FAL$SERVER account, which is referenced from other nodes using <NODENAME>::INFO.TXT - for example SLAVE::INFO.TXT
[MSW]SLAVE$ type slave::info.txt
Marks Office, Windermere, UK
(a working set of computers - definitely not a 'collection' ;)
BUBBLE and SLAVE serve the HECnet.eu website via WASD
BUBBLE has a captive account, NETHACK, password NETHACK for playing, you guessed it, nethack.

I've been meaning to do something with these for ages and add some more info to hecnet.eu, but I held off because I wasn't sure whether people wanted this level of information available across the internet.
Regards, Mark.
And now I'm seeing quite a bit more traffic on my router!

Subject: RE: [HECnet] Multinet circuit costs
where DECnet *might* get confused.
Well, this is easy enough to test experimentally. I've disabled the
redundant Multinet links on LEGATO, so in theory there should be no
redundancy now at least as far as LEGATO goes.
This means not only disabling the direct links from LEGATO to other bridge
nodes (e.g. GORVAX, SG1) but _also_ the links from LEGATO to other nodes
that in turn have Multinet links to bridge nodes (STUPI, FRUGAL, ROOSTA).
In theory I suppose the latter step is excessive since we can assume that a
two hop path would always cost more than a one hop path, but there's no
guarantee of that. So just to be safe this absolutely eliminates redundant
paths.
I think that leaves me with area 54, CIERE, as the only machine that
_only_ gets its connectivity thru LEGATO. That link I've left turned on.
Now LEGATO sees the path to everything except CEIRE as being thru the
bridge (QNA-1), which is what we'd expect.

Try your file copies again and see if anything changes...

Works for me!

This happens because when there are multiple routing nodes for the same
area, DECnet uses the one with the highest address. The obvious solution
would be for Johnny to renumber MIM as, say, 1.1023.
Hmm.
CTAKAH is set to lower router priority than MIM. I thought this is enough to tell that MIM is preffered router...
There's no need for CTAKAH to be and area router, so I'll downgrade it to endnode...
