Greg,
The issue you will run into is that in the case of the bridge or even Multinet the other end has no way of knowing that your IP address has changed. A bit of DCL trickery is used on SG1:: to deal with this for Multinet. As a result, SG1:: supports dynamic-DNS (remote) links. It does a "MULTINET NSLOOKUP" of the remote periodically (this is configurable), compares it to what it has in a private database, and "fixes" it if it has to. After that it reestablishes the link. Each dynamic IP address MUST use a dynamic-DNS provider or SG1:: will not be able to do the lookup.

Hello!
Okay please visit http://www.gregg.levine.name and that site lives
here, and resides on the Linux machine that Fred and were I discussing
earlier today. It is connected to the Internet via a router and a DSL
device. That device gets an IP address and it tells the router, both
are created dynamically via the PPPoE functions as assigned by the
service provider who is Megapath.
To have my system serve my webpages rather then have a hosting entity
do that I would need to, (and have done so) set up (or even arrange)
an account with any of the dynamic DNS service providers. I chose DDNS
to do so, and they went along with my choice of host name and offered
many suggestions on the methods of confirming that the hostname is
registered and is working. I chose to allow my router do one, and the
computer runs a program every few days to do the other one.
That's what I was getting at. Since this is a commercial router as
offered by Cisco, I'm not sure if it understands how to route the
stuff that's used for communications via the connected systems here.
I am of course looking at other methods to communicate with everything
out there besides the others people use. Speaking (or writing)
hypothetically, would a copy of Pathworks/32 work to communicate with
the others out there?

Look at LEGATO::INFO.TXT. Bob wrote up the definiition and includes it

That's why the file format allows it to contain information about

the single INFO.TXT on your gateway machine.
Cool. I might have forgotten some details. Looking at MIM::INFO.TXT, I
realize that it does mention the machine name, but I don't know for sure
if the file on MIM:: follows whatever format INFO.TXT should be in
nowadays.
We should try to get a formal definition for that file in writing
somewhere.

The file can handle multiple machines. Just look at SLAVE::INFO.TXT or
LEGATO::INFO.TXT or even SGC::INFO.TXT. Each of these files contains an
entire DECnet area of machines.

Someone (I don't remember who) had a suggestion a year or two ago,
that
machines should have a file in the default DECnet directory, with some
basic information about the node in a defined format, and the file
with
a defined name, so that anyone could easily extract and figure out
information about atleast running nodes.
Maybe that idea could be expanded upon?
Seems very tedious for people to constantly mail updates... Although I
could of course take additional information as I'm already keeping a
nodename database in Datatrieve. No big deal to add additional
information if we'd like that... Then I can generate any kind of
reports
based on this. As can others (if they can get remote Datatrieve to
work
against RSX.)

The information is not readily available thru NCP. Possibly NCL has a

pretty much the only phase V owner.
NCP gives limited information: the set exec node and sho exec (char)
commands only tell you the os name. For vms it tells you what
platform.
The excel file contains this information for each node in a single
cell:
<address>-<name>-<hardware>-<os name>
Mark the hyphens: that way I can manipulate the csv file easily on
vms
with f$element ;-)
So anyone who mails me node data in the format listed gets data
included in the file. What do you think?

Sorry, I'm confused. Is it your plan to keep a manually updated
list of
all of HECnet? Are you looking for data on all known nodes, even
end
nodes
and ones that don't normally run 24x7? And how much data do you
want
for
each node? OS? Hardware type? Geographic location?
That's fine with me and I'm not complaining in the least if
that's
the
case! OTOH, I thought you were making a list of the active routing
nodes,
which is an entirely different matter.
Well, both. I generated list of active nodes and I believe it
will
not be too
hard to manually update it from time to time.
I can add whatever interesting information and I can add any
number of
editors. Any volunteers? Hans?

Gha! I was trying to remember who might have been around back then. So that was you... I think that makes you the first place outside my own experimentation that was connected to HECnet. :-)
I believe that is correct. I don't remember anyone else being connected then.
Serial ports was my first solution. It seemed like a very easy thing to do, and it worked just fine. The only "problem" was that DECnet over asynch serial ports are slow, since they are limited to 9600 bps.
I might have run with that for at most a year before I wrote the bridge program to replace it.
I also needed physical serial ports all over the place. :-)
Yeah, it was a good first step though. Got the ball rolling. :)

Magica is still around. I only wish I could turn her on more often. Cooling is the problem.
I really need to go dig my /70 out and start running it one of these days. That and my /34a. I don't currently have anywhere appropriate to run them, however. :(
Hum...? I think that it terminated on our VAX 8650.
That is the only thing I can remember on which I had serial ports to spare. Running Ultrix on the machine at the time.
Maybe that's it and I'm misremembering. I remember it ran Ultrix but remember it being MIPS for some reason.
That machine is also still around, but also powered off because of cooling. Big ECL machine. Lots of heat... But it's KRILLE (1.8).
It can boot VMS, Ultrix and NetBSD. Only got DECnet for VMS though.
Yeah, a shame it's too expensive to run. Nice machine.
