The WendzelNNTPd is an IPv6-ready Usenet server that aims to be as easy to use as possible. It is portable, supports AUTHINFO authentication, contains ACLs as well as role based ACLs (RBAC), supports invisible newsgroups, and features automatic prevention of double postings. WendzelNNTPd supports MySQL as well as SQlite3 backends.
alph implements and analyzes historical and traditional ciphers and codes, such as polyalphabetic, substitutional, and mixed employing human-reconstructable algorithms. It provides a pipe filter interface in order to encrypt and decrypt block text to achieve transparency. The program is meant to be used in conjunction with external programs that transfer data, resulting in transparent encryption or decryption of information. The program can thus be used as a mail filter, IRC filter, IM filter, and so on.
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.
nget is a commandline NNTP file grabber. It automatically pieces together multipart postings for easy retrieval, even substituting parts from multiple servers and newsgroups. It handles disconnects gracefully, resuming after the last part successfully downloaded, and caching of header data for quick access. It automatically downloads only as many par/par2 files as needed.
