Free compact software for linux

Compact Filter is a network packet filter for Linux. It features an easy-to-use compact filter representation and high performance.
The main features are: easy to use interface, compact filter representation (memory efficient), and very high performance.
A difference between CF and other firewalls, such as Netfilter, is its representation of the ruleset. In CF the user writes a filter which is then compiled and optimized in user-space. The optimized filter is then loaded into the kernel (using netlink). Consequently the in kernel packet filtering code only needs funtionality for setting up a filter and filtering packets, while the more complex code of optimizing the filter remains in user-space.
Because of the continuous increase of the bandwidth and the security threats, firewalls have to evolve towards more efficient filtering schemes. The truth is that the existing scheme does not scale so well with the combined growth of bandwidth and rulesets.
Our aim is to try another approach to perform packet filtering where we minimize the complexity of the filtering process. This result in, both, a reduction of the required CPU power to filter packets and a simpler (and smaller) kernel code. Of course, we are pushing all the smart and complex part out to the user-space, but, developing in user-space is much simpler and safer.
Enhancements:
- changed -d option to delete all filters
- added -D option to delete a specific filter
- changed default policy to permit rather than deny
- added -l option on flex to support --yylineno on older versions of flex
- new and improved install guide

compact system monitor is a small and compact system monitor for SuperKaramba.

Credit where credit is due, i think i stole the icons from Borealis? Nice are they not? And the idea from someone else.

The theme can be changed somewhat by editing the theme and comenting out some lines.

Hope you like it! Its my first!

The Compact Flash Linux Project is a Linux distribution designed to run on a compact flash card in read-only mode. It is as small as possible, and currently needs around 14 MB.
Compact Flash Linux Project includes OpenSSH, quagga, iptables, hostap, madwifi, wireless-tools, pppoe, tcpdump, bridge-utils, and more. The initial release was v0.1.1, dated January 8, 2004. Version 0.1.4 was released July 23, 2004.
Enhancements:
- Many packages were upgraded.
- The package manager was improved a bit.

dk.brics.automaton project is a Java package that contains a DFA/NFA (finite-state automata) implementation with Unicode alphabet (UTF16) and support for the standard regular expression operations (concatenation, union, Kleene star) and a number of non-standard ones (intersection, complement, etc.).

In contrast to many other automaton/regexp packages, this package is fast, compact, and implements real, unrestricted regular operations. It uses a symbolic representation based on intervals of Unicode characters.

OSSP str is a generic string library written in ISO-C which provides functions for handling, matching, parsing, searching and formatting of ISO-C strings.
So it can be considered as a superset of POSIX string(3), but its main intention is to provide a more convenient and compact API plus a more generalized functionality.
Installation:
To install the Str library into /path/to/str/{bin,lib,include,man}/ perform the following steps in your shell:
./configure --prefix=/path/to/str
make
make test
make install
This installs at least a static variant of the Str library and when your platforms support it, also a shared library variant of the Str library.
Enhancements:
- str_parse(3) was fixed so that the va_list argument is no longer incorrectly used twice for processing the arguments, which led to segmentation faults.
