Werc is a minimalistic RESTful Web application framework and content management system. It follows the Unix "tool philosophy" and it is designed to be fast, simple, convenient, and easily extensible. It handles both small and big sites and has a flexible system for user and group permissions. All data is stored in plain text files that can be easily manipulated with standard tools, without using any databases or other external dependencies. Existing applications include a blogging engine with RSS/Atom feeds, a wiki system that can easily integrate pre-existing documents (can be enabled for any directory tree), and others.
The Heirloom Toolchest is a collection of standard Unix utilities. It was derived from original Unix material released as open source by Caldera and Sun, and contains multiple versions of each utility corresponding to SVID3/SVR4, SVID4/SVR4.2MP, POSIX.2-1992/SUSV2, POSIX.1-2001/SUSV3, and 4BSD (SVR4 /usr/ucb). It processes lines of arbitrary length and in many cases binary input data, supports characters in UTF-8 and many East Asian encodings, and contains more than 100 individual utilities including bc, cpio, diff, ed, file, find, grep, man, nawk, oawk, pax, ps, sed, sort, spell, and tar. Extensive documentation is included.
log4sh is a logging framework for shell scripts that works similar to the other wonderful logging products available from the Apache Software Foundation (e.g. log4j, log4perl). Although not as powerful as the others, it can make the task of adding advanced logging to a shell script easier, and has much more power than just using simple "echo" commands throughout. In addition, it can be configured from a properties file so that scripts in a production environment do not need to be altered to change the amount of logging they produce.
FIAIF is an Intelligent Firewall. It provides a highly customizable script for setting up an iptables-based firewall. Configuration is done through one configuration file for each network to which the firewall is connected. FIAIF supports masquerading, port forwarding, traffic shaping, and more.
