Diald manages network links, particularly on-demand links such as dial-up SLIP or PPP. It can also be used to manage and/or monitor any network interface. Diald monitors traffic on the link and makes intelligent (and highly configurable) decisions as to when the link should be brought up or taken down. The included control program, dctrl, runs on any system with Tcl/Tk (yes, even Windows) and allows diald to be controlled and monitored remotely.
The EnRus dictionary tools are TCL/Tk scripts for reading a textual (plain or compressed by gzip or bzip2) dictionary base and compiling new dictionary bases from plain text files. It consists of a few TCL console scripts and a Tk interface to them. It is configurable for different languages. The dictionary base may contain proper formatting and output procedures.
The Event monitor project is an approach to network management based on message passing between manager and managed nodes. It's based on a client/server platform, where the server is the manager node, and all clients are managed nodes. This tool is under development, but has lots of features implemented, like a graphical console, message passing layer, one disk monitor and clients for sending messages (both API and binary forms are provided).
GASP is a generic protocol encoder and decoder. It offers a complete scripting language (based on Tcl) which allows you to construct or analyze any packet of data based on abstract protocol definition. This version includes all the basics networking protocols (IP, ARP, ICMP, TCP, UDP, and DNS), some protocols for archivers (ZIP, GZIP, and TAR), and some multimedia protocols (JPEG, GIF, and PNG).
GNUlpr version 1.0 is a complete printing system based on LPR, and provides support for printer-specific options, GUI tools, and autoconfiguration. The 1.1 tree is a completely re-thought printing system. Rather than creating an all-powerful spooling daemon, it constructs a pipeline of "filter" programs to perform tasks (spooling, data stream type conversion, authentication, network protocols, etc.).
