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 …

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.

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 …
[View More]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.

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 …
[View More]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.

Thanks for the heads-up I'll sort that out this evening.

HECnet is a closed society, so I don't worry about it.
Ha, wasn't a security issue as much as a clueless operator issue ;)

Yes I have problems wihile copying files from Legato and Star69 to Ozon.
STAR69 has no public user account, and IIRC won't allow file access via DECnet without a username and password. I haven't got around to figuring out how to set up non-privileged file access in a safe directory yet.
Could this be the issue? I really am a total newbie so STAR69's capabilities are the absolute minimum needed to do it's job at present.

The circuit costs here are set to 4 for LAN and 3 for tunnels. The issue may be that if a node (at the end of the chain so to speak) has 2 tunnel links of the same cost and that the final destination costs the same I could see where DECnet *might* get confused. Let's look at the following contrived example:
FRUGAL:: connects to LEGATO:: - cost of 3
FRUGAL:: connects to SG1:: - cost of 3
LEGATO:: connects to GORVAX:: - cost of 3
SG1:: connects to GORVAX:: - cost of …
[View More]3
Fred, on node FRUGAL:: tries to copy a (large) file from GORVAX:: to FRUGAL:: *may* see some issues. On the other hand if Fred chooses to favor SG1:: over LEGATO:: (cost wise) he should not see any problems: Ex:
FRUGAL:: connects to LEGATO:: - cost of 3
FRUGAL:: connects to SG1:: - cost of 2
The route is guaranteed to be the same for the entire transaction. It will be (using poor man's routing to demonstrate) FRUGAL::SG1::GORVAX:: at a cost of 5, not FRUGAL::LEGATO::GORVAX:: at a cost of 6.

I can copy to Legato alright.
