Since you and Bob are both HAM's; what is the distance between your
stations?? Is IP over radio a ridiculous idea?? It is non-commercial
traffic.? I had heard something about this a few decades ago, so I'm
probably whaaay out of date.
Also if you set your paired DNS clients to the Dynamic DNS server of
your Dynamic DNS vendor, then as soon as your client updates the
service, that will update their local servers.? What takes time is the
'propagation delay' of the update going to other providers.? I can't
speak to all Dynamic DNS vendors (I use DynDNS) and this might not work
for you.
I have done stationary mobile connections; they can be tricky to keep up
24/7 and with most carriers, there are monthly CAP's to be contended
with.? The CAP is not much of a concern unless you are transferring a
lot of data.? Even doing FAL/DAP testing, I doubt I cleared a couple of
megabytes.? What burns up the CAP is multi-media.

This sounds promising! I am interested in at least
running some experiments to find out how well it all works, and to learn enough to
configure my future little patch of DECnet. I'd like to have fun participating, but
not if it causes problems for my upstream node or HECnet in general. I know that my
connectivity situation is unusual.
I am in southern California as my callsign suggests, just outside Riverside.
Is there any possibility of connecting through something like an SSH tunnel, and relying
on that for a higher level of security and authentication for the link than the DECnet
protocols natively provide?
If I'd like to eventually connect several nodes on my local network into HECnet,
would I need to consume a whole area number? Or is there a means for further routing
within an existing HECnet area? I still have much to learn about DECnet. Looking through
the HECnet node list, it looks like I could stake a claim on a batch of dog-related host
names without treading in somebody else's naming conventions.
I agree that dynamic DNS is probably not quick enough for my dysfunctional use case.
Sometimes my connection flaps up and down rapidly. I'm not sure if I could even accept
an incoming connection, or if my cell provider is doing NAT and/or firewalling that would
preclude that. I don't understand yet what makes my cellular connection quality so
variable. Maybe loading on the local cell towers? Neutrino flux? Demonic corruption?
Oddly, when my cell phone reports a "5GE" or "LTE" connection, I
expect a poor experience. Everything works best when it's reporting "4G". My
connection quality at any given time unpredictably ranges from "doesn't work at
all" to "play World of Warcraft for hours with no issues". It's
frustrating, but that's the price I pay for living on a nice, big patch of dirt
instead of in suburbia.
My current physical hardware includes my VAX-11/730, a PDP-11/34A, and a planned future
PDP-11/44 project. All of the physical hardware is waiting in varying states of disrepair
for me to give it more attention, so I'll use SIMH simulations for semi-regular
activity. My VAX-11/730 has formerly run, but it's presently waiting for me to fix
some mouse damage. My PDP-11/34A is a work in progress; I've gotten the CPU working,
but the big Fujitsu SMD drive it came with has a dead power supply that I haven't
debugged yet. I don't know what's on its hard drive. I'll probably run RSX-11M
on it, at least part-time? My PDP-11/44 is still a pile of dusty boards, an even dustier
pile of chassis to Frankenstein together, and a twinkle in my eye.
Has anybody else been on HECnet with dialup-like, or even (gasp!) mobile connections?
