Guys,
Looking to tap into your collective knowledge.
I'd like to set up a 3G dongle for the DEC Legacy event.
The plan will be to add my machine as an area router then other

Steve Davidson has pointed out that there are decnet numbers allocated
for experimental purposes.
I think I understand how to setup my 3G dongle to connect to the
internet via an ubuntu machine. I am happy setting up a DHCP and DNS
server on the same machine. The bit I don't understand is how I would
fit the hecnet bridge into this network. Normally on my DSL router I
have a port redirection rule setup on port 4711 to point to a Debian
based box on my LAN.
How would I achieve the same effect on a linux box? If I run the bridge
on the same box, does this negate the need for a rule?
If all this works, is there a restriction of one decnet area per lan
segment? Can I run two areas on my side of the bridge?
Thanks for the help, Mark
In general, if/when you have a setup like that, it's the same as if
you connect your computer directly to the internet. So, your Linux box
is at the same location your DSL router is. So, there are no rules to
setup to pass a packet through the router. The reason for the rule is
that your DSL router acts as a firewall (and possibly NAT), which is
what you need to circumvent for the bridge. No firewall/NAT box in
between means no need to punch a hole through it.
So you should be able to run the bridge directly on that box, and it
should work. All however, also depends on what your mobile operator
might be doing...
Area number for experimental is probably not going to help you,
though. You already have an area. Adding more nodes to it is hardly
any different than having a new area setup, except that if you setup a
new area, you will need an area router for it. I don't really see much
point in the "experimental" area we have reserved, but since we have
plenty of areas anyway, there is no harm in it. Anyone using that area
can expect things to not work though, as someone else might also be
using the same area, and conflict/confusion might follow.
As for having several different areas on the same lan, no problem.

Hi Johnny,
Thanks for clarifying that. I'll need to supply a node allocation to
participants before the event, and as I am sending out an email shortly
I'd like to provide the most accurate picture of what we can do - and
have an answer when people ask. I'll be taking my AlphaServer 1000A
(nodename SLAVE) which is acting as an area router for area 4, so I can
just plug that in and it will work. Is it best then to give you some new
node names before the event for area 4, depending on how many people
want to participate?
Just to clarify: there is no real need to provide nodenames. DECnet don't have a concept of a centralized nodename database. I just try to keep one around for our own convenience. For an event like this, just node numbers needs to be organized. People participating can then define their own nodename database to their hearts content. Every machine on a DECnet can have their own nodename database for the network, which don't have to match anything anyone else have anyway.
If you want to provide some sort of service in this area, what you could do is take their requests, and set those up on a machine you have there, and then tell them to copy the nodename database from you to have them have some kind of unified, consistent view. On that machine you can also have the nodenames setup for the rest of HECnet, so that they get those too...
And if there are name conflicts, you can decide how you want to handle it. Probably, in most cases, people there will be less interested in random nodes on HECnet than their fellow participants in the event, so you might want to allow them to grab "used" names anyway.
So, bring SLAVE:: to the event, and use that as a central source for nodenames for participants at the event. Afterwards you can re-copy the nodename database from MIM:: to get you back to the "normal" life.
And you can let them use any nodenumber you want on area 4, except the one you have SLAVE:: have, I guess. :-)

The power comes on and stuff happens, but no diagnostic beeps or anything.
Could it still be the power supply?

Hello!
Checked the power supply? It might have blown the fuses/circuit
breakers on it. What was it doing before it unceremoniously shut
itself down?

I've also found that my Vigor 2800 supports wireless dongles, which might make life incredibly simple. It's going to be one that either works or it doesn't.

Mark,
Since my phone only allows topposting I've deleted the original text. Your question was how decnet devices get their names.
The letters indicate the controller, they tell you what hardware is in use. So UNA indicates a DEUNA and ESA an on board controller for a microVAX. After the hyphen follows the controller number, the first interface is nr 0.
VMS device names differ: two ethernet controllers may be called EWA0: and EWB0: in VMS and be known in NCP as EWA-0 and EWA-1.
The name for the circuit is the same for the line (AFAIK).
Serial interfaces (for DDCMP) or CI interfaces follow different rules.
