Buffalo Linux:

BeatrIX Linux is a compact (less than 200MB) operating system aimed at both office and home users who want something simpler, safer and superior to Microsoft Windows, and that will run on just about any IBM-compatible PC made in the past 10 years. It runs as a live CD or it can be installed to hard drive.

CensorNet Linux:

CensorNet is an Internet Management Appliance designed to control and monitor individuals accessing Internet resources on a local area network. This dedicated server inspects all inbound and outbound data and decides, based on configurable rules, whether the individual or workstation concerned has the correct access profile to allow the request to be completed.

Crux:

CRUX is a lightweight, i686-optimised Linux distribution targeted at experienced Linux users. The primary focus of this distribution is "keep it simple", which is reflected in a simple tar.gz-based package system, BSD-style initscripts, and a relatively small collection of trimmed packages. The secondary focus is utilization of new Linux features and recent tools and libraries.

Damn Small Linux:

Damn Small Linux is a business card size (50MB) Live CD Linux distribution. Despite its minuscule size it strives to have a functional and easy to use desktop. Damn Small Linux has a nearly complete desktop, including XMMS (MP3, and MPEG), FTP client, links-hacked web browser, spreadsheet, email, spellcheck (US English), a word-processor, three editors (Nedit, nVi, Zile [emacs clone]), Xpdf, Worker (file manager), Naim (AIM, ICQ, IRC), VNCviwer, SSH/SCP server and client, DHCP client, PPP, PPPoE, a web server, calculator, Fluxbox window manager, system monitoring apps, USB support, and soon it will have PCMCIA support as well. If you like Damn Small Linux you can install it on your hard drive. Because all the applications are small and light it makes a very good choice for older hardware.

Debian Linux:

The ISOs are small enough to burn to a 8 cm (3 inch) CD-R/RW (although they'll also work on 12 cm/5 inch CD-R/RW media), and contain enough packages to install a functional version of Debian woody without going to the net -- all packages from required, important and standard are included, as are emacs21, postfix, ssh, and gnupg when they fit. A complete list of included packages is available in the .packages file for each architecture. Unlike most "netinst" ISOs, they will install a useful console-based subset of Debian woody without any extra packages downloaded, and provide all the tools you should need to install a complete Debian with any sort of network connection - PPP dialup, ISDN, (A)DSL, cable modem, or LAN/WAN.

Devil Linux:

Devil-Linux is a CD-based Linux distribution for firewalls and routers. The goal of Devil-Linux is to have a small, customizable and secure (what is secure on the Internet?) Linux. The future of Devil-Linux will go far beyond an ordinary router, we will provide a lot of other services, but the distribution will still be easy and fast to maintain.

DragonFly BSD:

DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series.

Feather:

Feather Linux is a Linux distribution which runs completely off a CD or a USB pendrive and takes up under 64MB of space. It is a Knoppix remaster (based on Debian), and tries to include software which most people would use every day on their desktop.

Gentoo Linux:

Gentoo Linux is a versatile and fast, completely free Linux distribution geared towards developers and network professionals. Unlike other distros, Gentoo Linux has an advanced package management system called Portage. Portage is a true ports system in the tradition of BSD ports, but is Python-based and sports a number of advanced features including dependencies, fine-grained package management, "fake" (OpenBSD-style) installs, safe unmerging, system profiles, virtual packages, config file management, and more.

GeeXboX:

GeeXboX is a full operating system, running under Linux and based on the excellent MPlayer. No need of hard drive, you just have to put the GeeXboX bootable CD into the CD-Drive of any pentium-class computer to boot it. Moreover, GeeXboX is a free software, created thanks to many open-source software. This means that everyone can modify it and build his own release of the GeeXboX.

INSERT Linux:

INSERT (the Inside Security Rescue Toolkit) aims to be a multi-functional, multi-purpose disaster recovery and network analysis system. It runs from a credit card-sized CD-ROM for convenient transport or download and is basically a stripped-down version of Knoppix. INSERT provides full read-write support for NTFS-partitions using captive-ntfs.

Kurumin:

Kurumin Linux is a Brazilian run-from-CD Linux distribution based on Knoppix. Its main features are excellent hardware auto-detection, support for Brazilian Portuguese and small size - the size of the ISO image is under 200MB.

Lamppix Mini CD:

LAMPPIX is a Linux live CD based on Knoppix and Damn Small Linux. It comes with the XAMPP web server, MySQL database, PHP and Perl scripting languages, as well as other tools to run PHP-driven web pages directly off a CD-ROM.

Linux LiveCD Router:

Linux LiveCD Router is a Linux distribution designed to share a broadband connection over WiFi. It can be used with DSL, cable modem, T1, ISDN, and dial-up connections. It can also be used it as a firewall, or as an access point for most WiFi cards. Linux LiveCD Router does not require any installation, but requires a dedicated computer to boot and run the CD.

LNX-BBC:

The LNX-BBC is a miniature Linux-based GNU distribution, small enough to fit on a CD-ROM that has been cut, pressed, or molded to the size and shape of a business card. In 1999 Duncan MacKinnon, Tom Crimi, and Seth David Schoen started work on the project at Linuxcare. Linuxcare printed 10,000 copies of the "Linuxcare Bootable Business Card" to be distributed at the then-upcoming LinuxWorld Conference and Expo. The give-away mini CD-ROMs were a huge success and have generated steady praise and thanks for their rescue capabilities, attracting many other developers to the project. The BBC went through seven versions, five of which were pressed into business-card sized CD-ROMs and handed out at trade shows or distributed by mail to Linux User Groups around the world.

Local Area Security:

Local Area Security Linux is a 'Live CD' distribution with a strong emphasis on security tools and small footprint. We currently have 2 different versions of L.A.S. to fit two specific needs - MAIN and SECSERV. This project is released under the terms of GPL.

Morphix Combined-Light GUI:

Morphix is a derivative of Knoppix, another live CD distribution. Morphix is modular; this means that it consists of a number of parts which together form a working distribution. What does this mean to a normal user? Well, that's the good part: it doesn't even know about the modules. They are invisible to it, save the startup-output on the console. So, if you don't care about how it works, just grab one of the combined ISOs and boot it! There are different pre-made cd images with a whole range of (currently GUI-centered) software. It has an easy-to-use installer, if you wish to install it to your harddisk, but it doesn't need to be installed. It doesn't touch the rest of your system without specifically asking you.

MuLinux:

This is an ISO image of the system, able to boot from the CD-ROM and run without the hard-disk. The CD-ROM is based upon muLinux with many added packages.

SystemRescueCD:

SystemRescueCd is a linux system on a bootable CD-ROM for repairing your system and your data after a crash. It also aims to provide an easy way to carry out admin tasks on your computer, such as creating and editing the partitions of the hard disk. It contains a lot of system utilities (parted, partimage, fstools, ...) and basic ones (editors, midnight commander, network tools). It aims to be very easy to use: just boot from the CD-ROM, and you can do everything. The kernel of the system supports most important file systems (ext2/ext3, reiserfs, xfs, jfs, vfat, ntfs, iso9660), and network ones (Samba and NFS). SystemRescueCd is based on the Gentoo Live CD.

Slax:

SLAX - Live CD is a bootable CD containing a Linux operating system. It runs directly from CD-ROM without installing. The live CD described here is based on the Slackware Linux distribution and is downloadable from its website as an ISO image. All scripts and source code which can be used to build your own live CD are also available.

Smoothwall Linux:

SmoothWall was first released to the world in July 2000. SmoothWall is designed by administrators and security people, priced at a price that is easy to access and with the GPL taster product you get a glimpse of something that the established security manufacturers and companies should be scared of. We're putting control BACK in the hands of the user, without the need for being ripped off with exorbitant hardware firewalls that are oversold and overpriced, without the need for being ripped off with exorbatant hardware firewalls that are oversold and overpriced.

Trustix Secure Linux:

Trustix Secure Linux is a Linux distribution targeted at companies, of all sizes, in need of a low footprint and high security server operating system. Trustix Secure Linux includes the open standards based SoftWare UPdater, SWUP, which keeps all software packages up-to-date, resolves library dependancies and integrates public key cryptography to ensure safety and security.
