Johnny,
I'll have to look up which documentation - I do not have it in front of
me at the moment. I personally use my own area to deal with this
because I am way past having to need the documents.
I have written a DCL procedure that does IP address lookups at
predetermined (configurable) intervals. If it finds a mismatched IP
address it reconfigures the the TCP-0-n (where "n" is the area - in my
case) IP address and schedules a reboot. It takes SG1:: ~3 minutes to
come back. I had to do this because Multinet (like the bridge) does not
support dynamic addressing. Area 33 is running with a dynamic-DNS
address. It just works and has for well over a year. It also sends
email to those who need to know that a change in address has occurred.
This can help Sampsa and Bob (two other connections that MISER::FRED
has) to notify them that they must reconfigure the entry for area 33.
Initially we used it to give MISER::FRED information to take to his ISP
that would detail just how often he would have to deal with new
addresses. Fred could probably provide more info on this. The email
also contains a report that provides some details that could be useful.
It has sure helped Fred and myself deal with "dynamic" changes! :-)

Could you point me to some of that documentation? I've not seen any of
it, and I don't really at all understand the point of even setting up
information in the nodename database for DECservers, which don't even
speak DECnet to begin with. (And I do have DECservers up and running, as
well as manuals...)
I know that, from a convenience point of view, you can use the name as a
short cut for specifying the MAC address and circuit, but having an area
reserved for such a simple detail seems excessive.
Second SG1 is a VS4000/30 (VLC). It is small, quiet, and cheap to run
-
all very important features. If I remember correctly, LEGATO is the
same platform for the exact purpose. The only difference between my
Multnet "gateway" is that it can accommodate dynamic-DNS at the other
end.
Cool. I guess that platform should be enough to handle normal HECnet
traffic even if we grow some more.
How do you deal with dynamic IP addresses?
PS One more network is in the wings. You should be getting email
about
it soon enough if you have not already.
Nothing yet.

That is 14 areas, and I'm talking to one more guy who wants a new
area,
which would bring us to 15.
Anyone object to me giving him area 13? It was asked to be reserved
for
DECserver management, but I don't really see the point of having an
area
for that purpose. But if you can convince me... :-)
Also, SG1:: is quite a hub from the bridge point of view. Lots of
connections coming through there. Nice. :-) What type of machine is
it?

At the moment 13 areas are up and running - this list only show 10.
Hopefully sometime today we will be at 14. We're working on it! :-)

Cool. Area 3 is up according to MIM. Pretty...
