IIRC, you can find a daemon to interface with Multinet tunnels into the
Linux DECnet tools package. That should be a good starting point where to
discover what would be needed to write a new RSX interface, at least in
terms of packet structures and such. :)

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.

It's NOT nice to shake VAX 2000's, even though it probably needed it!
:-)
If no one else does I can once I finish getting things setup.

The only thing I know (from configuring my firewall) is that they are
UDP packets on port 700. I haven't looked to see what's inside the
packets, though.
Interesting. Could anyone grab a bunch of frames with tcpdump and send to me?

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???

I wonder if what I saw was VAX specific??? ...
No way for me to test now. As a bonus I found out that
$ multinet set/decnet/remote=new_IP_NAME/device=TCPAn:/connect
work as well as
$ multinet set/decnet/remote=new_IP_ADDR/device=TCPAn:/connect
