Re: HF UUCP (Was: Re: [BITX20] Best way to use #sbitx with N3FJP, WINLINK, other Windows ham radio apps?) #sBitx

 

FAscinating!? ?Does it work in reverse?? ?Can you RECEIVE email?

1.? ?The Winlink peolpe had to deal with the fact that receiving email?is 3rd party traffic and has to follow the laws.? ?They also wanted to completely avoid spam email.? ?They worked out very intricate systems to protect and allow workarounds for "emergency? break glass" situations.? ?
2.? The winlink people also came up with a large number of automated systems of knowledge, because they began with the maritime oceanic sailing community.? So for example if you are in the middle of the ocean, you can ask for and receive by email, a WEATHER MAP for your part of the ocean.? ?They have like about 40 different products you can receive in this manner, including news and other things you might really want to know.? ?Weather forecasts, yada yada yada.? ?they had to do a lot of legwork to make all that work, and to KEEP IT WORKING.? ?It has proven to be very useful during emergencies.? ?For example, I can pull weather information in the middle of a hurricane when other sources are no longer available
3.? The winlink network includes both peer to peer and client server and radio only.? ? Radio only was demanded by the US Government.? ?It provides automated, computer/radio to compuer/radio routing of email.? ?For example, I once deposited a radio-only email in Canada, and wihtin an hour it had been relayed (all without human inervention) through esablished servers along the USA East Coast, and was availble for me to receive.? ?When you arre?"radio only" -- there is NO INTERNET? ?So you cannot pick your mail by using your regular email vendor -- you must use a radio!? ?The email is cached for you at 1, 2 or 3 servers that you have pre-picked and are known to the system.? ?The radio only email is cached at all of them, mirror-like

Those folks have been at it for over 2 decades and have been used in just about every disaster you can think of, albeit peripherally.? ?They have a ton of "institutional knowledge" about "human behavior and needs" in those situations.? ?Missionaries, medical trips, a bunch of groups have taken advtange of their system.? ?Currently, ARES(R) groups all overr?the nation are using them, as have Red Cross systems.? ?Out of a war-torn area -- Winlink works.? ??

Despite the FCC prohibition of encryption, they found a way to provide fairly reliable "user identification" so as to avoid spoofing.? ?You can even use telnet to access their system....but it is PaINFUL.??

I hope this information is helpful.? ?A replacement system needs to provide all the same, or better, integration into human needs and behaviors in both normal and disaster/war days.??

Thanks for all you are telling me about!

Hi Gordon,

If later on anyone wants to put up a ham radio uucp HF gateway, As uucp
setup is not that easy, I can help with all the uucp setup for remote
and gateway stations (I have bash scripts and templates ready) and
provide server access to our *.hermes.radio (just choose a subdomain)
for initial testing, if needed. This is what we call "central" server,
with real IP in the VPS. The "gateway" station just relays emails to
"central" email server, and connects (or receive connection) to the
"remote" stations over HF. This is the topology I put in place. With
VARA and/or Ardop (this is what my uucp bridge supports [1]).

for example, to triger the connection to the gateway (and consequently
synchronize the uucp jobs, aka. emais), from a remote station, I just do:
uucico -S gw

where gw is a uucp alias to the uucp gateway nodename, and remember to
put the radio in the same frequency of the other station.

the uucp bridge automatically calls the nodename to be connected, which
in the case is the callsign of the station, for example, PU2UIT (the
nodenames must be valid callsigns for vara and ardop be happy).

Cheers,
Rafael
