Newsd is a standalone local NNTP news server for private newsgroup serving on a single server. It is useful for serving private newsgroup(s) to an intranet or the Internet, and can act as a simple mail gateway. However, it does not interface with other news servers and cannot manage distributed news feeds, i.e. Usenet news.
The NukePost script automates the process of removing multiple Usenet posts from Google's message archive, saving you the trouble of continually reloading and resubmitting Google's removal page. It requires an active Google utility account and the Message-IDs of the posts you want to remove.
PHPnewsGroups is a Usenet news client written in PHP4. It is completely Web-based, and the interface is very easy to use and does not require any particular Usenet knowledge. Just a few configuration files to edit and that's it. You can easily access and search all newsgroups with binary content.
PIMPPA automates file downloading from newsgroups and FTP sites. Its especially designed for leeching pictures but can be used for any files. Filename-based heuristics and MD5 checksums are used for spam/duplicate prevention and automatic sorting of incoming material. The whole process is cronable. PIMPPA also includes a GNOME GUI and several commandline utilities for further processing and management of the kept files.
