Speaking of Multinet and DECnet-over-IP. I just got this crazy idea to implement DECnet-over-IP tunneling in RSX, and it would be fun to be compatible.
Have anyone analyzed, or read any documentation on how the tunneling is done? TCP or UDP? Any additional headers or data in the stream in addition to the encapsulated DECnet packets?

Were you able to verify that the new address works? ...
Yes, with
$ mul sho/nosym
and I turned TCPAn on itself and circuit displayed correct node on
the other end :)
--
I can also confirm that this works. I'm well used to changing Multinet
interface ip addresses and other Multinet parameters on production systems
without rebooting so I was interested to try it. (The only reason I've ever
found for a reboot is to ensure the startup files have been reconfigured
correctly. I suspect this is why Process recommend it. If I liked rebooting
things, I'd get a PC)
I set up a DECnet-over-IP link between CEIRE and CHEKOV and turned off the
SVA-0 circuit on CHEKOV. I made sure that the only DECnet connectivity was
over the IP link. Then I changed CHEKOVs ip address, reconfigured
DECnet-over-IP and re-established the link. I was then able to SET HOST
across the link. No reboot required.
It took me a while because CHEKOV, my VAX 2000 would not co-operate. However,
after a good shaking, the RD54 spun up and it booted.

Peter Coghlan.

Rok,
Were you able to verify that the new address works? If I test this then
I will actually need one of the remote addresses to change. This is not
something I wish to ask of the two sites that currently make use of
dynamic-DNS. What I may do is setup one of my other machines with
Multinet and then move it to another of the static addresses here to see
what happens. That will take a bit more effort so it may have to wait
until the weekend.
Also, I can't remember if I wrote MultiWatch for V5.2, or V5.3 - it's
been in use that long... This could explain the difference. I just
don't remember. Maybe, Fred remembers - his site was the reason for the
procedure in the first place. Fred???

If I remember right Multinet caches the IP address and
does not flush it. Let's not forget that Process Software
does not support anything but a reboot!
My method works for me. Tested with MultiNet V5.3 on
FreeAXP OpenVMS V8.4.

Johnny,
I would like you to reenable the bridge connection to Sampsa. It will
be interesting to see the changes in the routing once this has happened.
The current picture while quite impressive for SG1 clearly is not the
real story (picture).
CHIMPY is offline so it should not be in the picture until after Sampsa
gets back from Finland.
Thanks.

Sampsa, I disabled you a few days ago when your connection (well, the
adjacency to MIM= was going up and down every few minutes for about two
days. I really dislike having so big logs with just CHIMPY up and down
messages... :-)
Are you more stable now?

Peter,
Add an additional connection to Multinet for SG1. Use 69.21.253.230.
I
would set your costs (because you are an "end node") as follows:
GORVAX = 3 Shortest distance and high speed
SG1 = 5 Medium distance and medium speed
LEGATO> 5 Longest distance and slower speed
According to Sampsa, his bridge link is having issues (I have no
access
to that), and he is out of country, so connecting to SG1 is probably
a
great idea for now and won't hurt anything. SG1 like LEGATO is a
dedicated Multinet router. All it does is that one function.

I'm everywhere, the Vaxen is in Stockholm, Sweden.
What is your IP address? I can add links to GORVAX and SG1 at any
time. If your IP address is dynamic, then SG1 will deal with that
automatically whereas GORVAX is a manual change.
192.108.200.211
It;s static.

Actually, we have booted DECservers across the bridge. This site has
done it several times in the past. I'm not sure about recently though.
I don't keep track of that anymore.

Subject: Re: [HECnet] Multinet Tunnel Links defined - area 13
As everybody here knows, Decservers don't use decnet but needed an entry
in the ncp database for MOM to figure out where the software was to be
found. Later on LANCP was introduced for that purpose.
Since we're not exactly short of areas, let alone node addresses there's
no reason why we cannot reserve an area for them. OTOH I doubt we'll
boot a decserver across the bridges (perhaps Sampsa will try that). So
I'll keep my DS100 in area 44, it is 44.8 (ASTAAT, At).

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

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?

Which since time I have switched ISP's (went from DSL to the local cable co) and now my address, while dynamic, is much more stable. I don't believe I've received an email from Multiwatch yet since I have switched and that was somewhere in ?-April-2011
However that being said, when I was on DSL and the address changed for no apparent reason, Steve's process worked well. A few minutes of downtime and the circuit came back up by itself.
