Projects / INN


INN (InterNetNews) is an extremely flexible and configurable Usenet / netnews news server. It supports accepting articles via either NNTP connections or via UUCP, as well as serving out articles to reading clients via NNTP. It supports multiple different ways of sending outgoing articles to other hosts, as well as multiple different storage mechanisms for articles and article overview information via internal APIs. Compared to other news servers, INN is more complicated with a steeper learning curve, but is extremely flexible and configurable, comes with a large suite of supporting programs, and supports embedded filters in either Perl or Python.

            There's fairly good documentation around, but most help I found at

            Even if you do manage to run a news server by reading man pages or FAQs, pay the group a visit. The wealth of knowledge there is great.

            Nice Software, Poor Documentation.
            This beast is a great piece of software; and it is a huge beast. It is really fast and really solid. Too bad the documentation sucks for the 2.2 series. The 2.2.1 install docs are all wrong. Good luck with it.
