Yes, that last part is what I am missing on the PDP-11. I could use more
details about that.
Supratim showed me the following commands that worked on the MV3900. The
second command gave be an error on the PDP-11.
$ mc ncp set node mim address 1.13
$ mc ncp copy known nodes from mim to both

Ok, a quick rundown on some of the more esoteric
details about lines and
circuits might be useful here.
First of all, Kurt, you might want to redo the NETGEN and not set the
system up for DECnet routing. It takes a lot of resources, and if you
don't really want it, you are much better off with a system not even
generated for it.
The question about remote nodes are just for an initial population of
your local nodename database. All you need there is really to define MIM
(1.13). You can then copy the whole nodename database from MIM over to
your machine that way instead. Let me know if you want some details on
that step.

Kurt,
If you want two circuits like UNA-0 and IP-0-0 I think you have to
be a routing node (but not an area router).
Not really, but maybe. If you define multiple circuits, and are an
end-node, only one circuit will be active. But others can exist, and the
system will fall back to some other circuit if the active one goes down.
So it can be used as a back connection.
However, even as an end-node, you can have several *lines* on and active
at the same time. And this is a trick to use if you want DECnet-over-IP,
but want to be an endnode. You need ethernet for TCP/IP to work, but you
do not want DECnet to use the ethernet circuit.
But you configure one IP line as well, and that is the one DECnet will
be using. Meanwhile, TCP/IP is using the ethernet line.
It might sound a little confusing, but think about it for a second, and
I hope it becomes clear. Otherwise, just ask, and I'll try to explain it
better.
Also, you should define all the nodes you want to
talk to with NCP in
one of the startup files or do it with CFE but I prefer startup so it?s
simple to change.
I would actually say that you wouldn't. Of course, there is nothing
wrong in doing this, but if you want the full HECnet nodename database,
it contains 700 nodes. That will take a while to type in.
However, you can copy the nodename database from another DECnet node,
and then use this.
But you need at least the nodename of someone where you will be copying
from to start with, which is why I suggested adding MIM at the start.
After that, there is [5,54]NNC which is the nodename collector task. Run
it, collect names from another node, and build a new database with this.
Then stop and restart the node name server, and you have all the nodes
defined.
(The node name server is managed by the command SCP.
So, SCP STOP followed by SCP START will do it.)
