Hey,
I've been playing around with NNCP and really love what I'm finding so
far. I've built a whole bunch of stuff on NNCP so far, including
a youtube-dl based video downloader and a Telegram bot that lets me
send/receive messages through NNCP. (The latter bot was something I
cooked up for use on a trip where I was going to have low connectivity
and it worked really well.) I also use NNCP as a way to access services
and commands on my LAN at home, which I expose through a relay node with
an external static IPv4 IP. I was wondering if others had built any
services on NNCP and if so what other folks been doing and what patterns
they've been using?
So far I've settled on a pattern of having `nncp-exec` commands actually
push a new line onto a FIFO. I have a daemon that reads from this FIFO
and uses it to actually perform work. This seems to not incur any
head-of-line blocking with NNCP. In the case of my youtube-dl downloader
this makes sense as a large media file may actually be a very large
download and take a while to finish. I plan on playing around with email next.
I've also encountered a few crashes which I noted down in a file I saved
in /tmp ... and yeah now I don't have it anymore. I'll see if I can
capture those crashes again so I can post this on the list. Anyway
that's all and sorry for getting a bit stream-of-consciousness.
Thanks,
Koushik

That is a really neat idea! Do you happen to have the source code
for that available somewhere that the rest of us might try it out
too?

I've built an apt-offline processor, which is used to install or
upgrade Debian/ubuntu systems.
On the Internet-connected box, I have an exec:
apt-offline: ["/usr/local/bin/apt-offline-proc"]
The script can just run apt-offline get $INPUTFILE --bundle
$OUTPUTFILE
then use nncp-file to send the OUTPUTFILE to $NNCP_SENDER
I also have scripts for receiving zfs or dar backups, and for
distributed syncing of git repos. See
https://changelog.complete.org/archives/tag/nncp for details.
I also run Usenet over NNCP, and offer NNCP Usenet feeds to
interested people.

It's all good, and welcome.

I just put some of the code on my Github. It's pretty raw, but should be
enough to get started with. I have the code for the send and receive
sides of the Telegram bot and the Youtube-dl downloader.
Youtube-dl Bot: https://github.com/Koshroy/yt-nncp
Telegram Receipt Relay Bot: https://github.com/Koshroy/telegram-nncp-bot
Telegram Send Relay Bot: https://github.com/Koshroy/telegram-send-bot
Feel free to let me know if you have any questions!
I have plans to convert the Telegram bot into a bot that uses an MDA to
actually relay received Telegram messages as mail, and then have a fake
MTA which parses incoming mail as messages to send out to Telegram. I'm
also planning on porting all of this to use the Matrix network as well,
but I have more friends/family on Telegram right now so that's what I'm
more interested in connecting first. I'm not super familiar with how
E-Mail works underneath so it's a bit of a learning experience for me.

Oh isn't this a bit dangerous? I've never used a flow like this so I'm
not sure, but isn't it a bit scary to apply package/system updates
completely unattended like this?

Oh, I might be interested in an NNCP Usenet feed!
Also, is there any group of folks exchanging mail over NNCP? I realize
that with this mailing list there might not be much of a need, but it
would be cool to exchange mail over NNCP! I've been wiring up a local
Postfix MTA to NNCP for use between machines of mine.
Thanks,
Koushik

Personally I used to use nearly everything listed in
http://www.nncpgo.org/Integration.html
but currently none of them. Just because now I even do not have a laptop
and my workflow requires less "async" jobs to do.

Initially NNCP was written for replacing UUCP as a transport for email.
For 10+ years I have not used POP3/IMAP4 for mail delivery to my laptop
(or other computer) at all. At the beginning my intermediate SMTP relay
server just waited when my end-point computer (laptop) will be available
and it will flush its queue over SMTP directly to it. Often I logged in
and manually called "postqueue -f". Later I switched to UUCP-over-SSH
transport and used it for years. And 5+ years ago I wrote NNCP as a
replacement. Since the very beginning of its existence it is used as a
transport for email (SMTP <-> NNCP <-> SMTP).
Also I extensively use it for files transmission: fire-and-forget
nncp-file invocations to send backups and everything I have to send to
other servers not immediately. Several dozens of files every day and all
email correspondence uses NNCP. Most time data transmissions use online
protocol, but at least once per week I use intermediate storage for transfer.
