Hi folks,

I thought I would mention various UUCP-related projects that I'm aware of.

=== (Pseudo-) active UUCP networks:

www.sdf.org offers UUCP feeds of email - https://sdf.org/?tutorials/uucp

on IRC chat.tilde.org, there is #uucp where people are working on a full UUCP network. There was information on https://tildegit.org/UUCP-Grassroots/incubator/wiki/Home until yesterday, which hopefully will reappear soon.

=== UUCP carriers

I have support for running UUCP over LoRA and XBee low-power, long-distance, license-free radios:




=== Running other protocols over UUCP

NNCP (see below) can run atop UUCP; see https://github.com/jgoerzen/nncp-tools/blob/main/docs/tunneling.org#uucp

=== UUCP modern derivative: NNCP

NNCP is basically a modern UUCP. NNCP is to UUCP what ssh is to telnet. It has built-in crypto (end-to-end) with tor-like onion routing, supports USB sticks and mounted directories as first-class transports in addition to network or stdin/stdout connections, doesn't require ssh for secure transport, etc. It is similar to UUCP in that it is source-routed store-and-forward. NNCP commands are syntactically different than UUCP but conceptually similar, and can be dropped in to replace UUCP with only config modifications for things like Postfix and Exim, and a small wrapper script for INN. See https://nncp.mirrors.quux.org/

From the website: "[NNCP is] -hoc friend-to-friend (F2F)
statically routed darknet delay-tolerant networks for fire-and-forget secure reliable files, file requests, Internet mail and commands transmission. All packets are integrity checked, end-to-end encrypted, explicitly authenticated by known participants public keys. Onion encryption is applied to relayed packets. Each node acts both as a client and server, can use push and poll behaviour model. Also there is multicasting areas support. Out-of-box offline sneakernet/floppynet, dead drops, sequential and append-only CD-ROM/tape storages, air-gapped computers support. But online TCP daemon with full-duplex resumable data transmission exists. "

There is an active public relay for NNCP: https://github.com/jgoerzen/nncp-tools/blob/main/docs/quux-relay.org

Usenet feeds are available over NNCP (using send-uucp.pl and a tiny wrapper script): https://github.com/jgoerzen/nncp-tools/blob/main/docs/usenet.org

NNCP can be tunneled over other transports, including Syncthing, AWS, ssh, radios, and of course regular TCP. https://github.com/jgoerzen/nncp-tools/blob/main/docs/tunneling.org

You can sync Git repositories over NNCP using its multicast areas support https://github.com/jgoerzen/gitsync-nncp/blob/main/gitsync-nncp.org

I have a blog series about NNCP, covering what I'm doing with it at https://changelog.complete.org/archives/tag/nncp . This includes airgapped ZFS backups (with up to 250GB packets),

Some more links from Sergey Matveev, NNCP author:

https://nncp.mirrors.quux.org/Use-cases.html covers things like satellite links, airgapping, etc.

https://nncp.mirrors.quux.org/Integration.html discusses integrating with Postfix, Exim, web downloading, Git, etc.

https://nncp.mirrors.quux.org/Comparison.html provides a comparison with UUCP.

=== Other discussion areas

comp.mail.uucp on Usenet still has subscribers and is periodically active.
