[HECnet] Intermittent Connection with PyDECnet?

[Robert Armstrong]

Mark,

 

  Are you in California?  You do have a “6” call, so I guess that’s a clue…

 

  Yes, I’m willing to give it a try.  Unfortunately with an intermittent connection and a constantly changing IP, the only practical connection option I can see is Multinet over TCP, AND with your end as the active connector and mine as the passive listener.  That means you can’t use the standard Multinet port 700 and a dedicated port will be required, and together that means some hand editing of the Multinet configuration file on your end.  And a dedicated router rule on mine.

 

  The only other option would be dynamic DNS, which seems less practical.

 

  Let me know if you want to proceed.

Mark - PyDECnet will work fine. If you are in CA, Bob's A2RTR is closest to you, he may chime in. Or you can connect to PYRTR in MD that I maintain. Or both.

 

There seems to have been great leaps in packet data over amateur radio. Your situation seems to be perfect for experiments there too. But another topic.

 

Let me know if you would like to connect to Uppsala via Maryland.

 

Best

No, I'm not complaining about intermittent connectivity with PyDECnet; I'm asking if it's possible!

I don't have persistent Internet connectivity or a fixed IP address at my just-barely-rural home. When my home network is connected to the Internet, it's tethered over my cell phone. And even then, my cell service is spotty. I could possibly resume using a separate hotspot at home rather than my regular cell phone, but even when I was doing that, my connectivity wasn't great. Cell service in my neighborhood isn't very good via either AT&T or Verizon, and wired connectivity is not available.

Would any of the DECnet routing mechanisms supported by PyDECnet possibly be suitable for intermittent connection of my home network, with a small number of DECnet nodes, to HECnet? Or am I just going to have to remain a HECnet spectator until I manage to obtain better Internet connectivity?


Yes. It is possible. If you use TCP as the transport, it can work with you having only intermittent connectivity, and different addresses.

Paul Koning will have to tell if PyDECnet can also act as a listener from some arbitrary remote system. But with RSX I can definitely do that. So if nothing else, you can always set it up so that you connect your PyDECnet to an RSX host...
