Free hardened linux 1.6.6 2 software for linux

Hardened Linux is a hardened distribution based on a minimalized Slackware Linux 11.0.
This distribution is still under heavy development.
Hardened Linux (a.k.a. "Wendzel Linux") is a security distribution with 3 main targets:
- maximum security
- maximum stability
- maximum usuability
It is optimized to run on as firewall system, vpn gateway, IDS system and authentication system. Currently not all of these features are fully implemented.
Enhancements:
- This just an updated version of the 1.6.6-snapshot release. This release includes our current packages (gcc-4.2, glibc-2.5, kernel 2.6.21.3 and different other package updates). Nothing else has changed. We released this new version because it will still take a few weeks (if not months) before we can release the next snapshot version that includes a completely new package system and a completely new installer system. Please report any kind of bugs.

Rubix is a Linux distribution forked from Slackware Linux.
It differs from its parent in that Rubix uses Arch Linuxs pacman for simplified package management with dependency resolution and it has a completely revamped init system, maintaining the BSD style, but adding modularity.
What is Rubix?
- It is a new Linux distribution that is something of a fork of Slackware 10.1.
- It will branch off in its own direction very quickly, in many ways, it already has.
- It maintains the Slackware traditions of Simplicity, Security and Stability.
- It will run on all i486 hardware and newer and is optimized for i686.
- It is designed to support mission critical hardware and be very admin friendly.
- It is a great distribution for knowledgable *NIX users!
- If you know Slackware, you will do great in Rubix!
How is Rubix different from Slackware?
- Rubix uses Arch Linuxs pacman for simplified package management with dependency resolution.
- Rubix has completely revamped the init system, maintaining the BSD style, but adding modularity.
- Rubix uses gcc 3.4.1 and compiles most packages with SSP (aka: ProPolice), and PIE (Position Independant Executable) wherever possible, but will never patch software just to make it compile with SSP andor PIE. This means that Rubix should not be thought of as a hardened distribution as many packages can not be compiled with SSP, however, it does mean that Rubix is harder than most. This logic makes most software more secure and does not require downstream patching for compatability, a major goal of Rubix.
Enhancements:
- This is the inaugural release of the Rubix Linux operating system. Rubix Linux is distributed with the Linux kernel versions 2.6.15.5, 2.4.32 and 2.4.32-grsec. Rubix Linux is well equipped to serve in both desktop and server roles. Rubix has exceptional hardware detection with udev replacing hotplug for 2.6 kernels and the latest KDE desktop version 3.5.1. Mozilla Firefox 1.5.0.1 and Thunderbird 1.5 are now the default web browser and email client. Rubix Linux also supports the best modern filesystems including ext2, ext3, JFS, XFS, ReiserFS and now Reiser4 (with 2.6 kernels) from installation.
