nntpserver.py: no-dependency single file NNTP server library

by epilys on 2021-09-06

Repository: https://github.com/epilys/nntpserver.py

No-dependency, single file NNTP server library for developing modern, rfc3977-compliant (bridge) NNTP servers for python >=3.7. Developed as part of tade, a web discussion forum with mailing list/NNTP interfaces which powers the https://sic.pm link aggregator.

Included example servers are:

example_server.py returning hard-coded articles
hnnntp.py querying https://news.ycombinator.com (hackernews) API and caching results in an sqlite3 database. A public instance might be online at nessuent.xyz:564 (TLS only)

^{https://sic.pm NNTP server that uses nntpserver.py

accessed on a Commodore Amiga with
NewsCoaster
client}

Running example_server.py:

$ python3 example_server.py --connect-with-nntplib
Listening on localhost:9999
Connecting with nntplib...
New connection.
