Binkd is a TCP/IP daemon which transfers files between two Fidonet systems. It supports so-called "Binkley-Style outbound", also supported by most Fidonet software. It uses its own protocol (called Binkp), but that's not a big problem, as binkd is perhaps the most popular Fidonet-over-IP technology in the former USSR.
FIDOGATE is a Fido-Internet gateway and a Fido tosser. The gateway converts between the worlds of Fido NetMail/EchoMail (or FTNs, Fido Technology Networks in general) and the UNIX mail/news system. FIDOGATE will convert Fido mail packets to RFC822/1036-style messages and vice versa.
The mgetty package contains an intelligent getty for allowing logins over a serial line (such as through a modem) and receiving incoming faxes. The companion program sendfax is used for sending faxes from the commandline or from other applications. The third main component is vgetty/vm which can be used with a voice-capable modem to implement an answering machine, a voice menu system, and similar things.
Turquoise SuperStat reads the contents of a Fidonet message area in one of its supported formats or Usenet news groups and creates toplists over massive quoters, senders, original content per message, Fidonet nets (Fidonet only), Internet topdomains, receivers (Fidonet only), subjects, and used software, as well as graphs over posting by weekday and time of day. It supports Squish, *.MSG, FDAPX/w, JAM, MyPoint, and tanstaafl's message area base format, as well as Usenet news groups over NNTP or in news spools. Command line and GUI versions are included.
JAMlib is a collection of subroutines that encapsulate much of the format-specific and tedious details of the JAM message base format. By using these routines, application programmers can concentrate on the higher-level issues of their programs instead of worrying about their JAM routines.
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.
RNtrack is a mail tracker/router for FidoNet-like networks. It's purpose is to process netmail on netmail hubs, though it can be useful for an ordinary node. It takes a letter, compares it with a mask and, if comparison was successful, it executes the corresponding operation with this letter. It works with popular message bases, MSG, PKT, Squish, and JAM.
