Free bootable software for linux

Phrealon is a bootable linux CD based on Slackware Linux 8.0 (now 9.0)designed to allow the easy imaging of multiple workstations.

It utilizes the udpcast set of Linux tools to accomplish this.

The DemoLinux CD allow to use Linux without installation, disk partitioning or any other complex manipulation that still prevent many people from giving Linux a try. This CD does not install Linux on your hard disk, but it allows you to play with it at lenght before you eventually decide to proceed with a full fledged installation.

This is made possible by a set of technical features in the Linux kernel and by some other free software (notably from S.u.S.E. and RedHat) that we use here.

Our goal is to allow everybody to make by himself an idea of what Linux can offer, and also to provide software publishers with a means to give out easy to use, no-hassle demos of their Linux products.

This CD is also a wonderful means of using Linux everywhere: you can take your favorite configuration with you in a CD that fits in your pocket, sit down in front of most PCs running another OS, boot from the CD and find yourself in front of your preferred environment in minutes.

Timos rescue CD set provides an easy way to generate bootable CDROMs with a ready-to-use rescue system on them. The system is designed to be fully customizable and easy to build.
The rescue system includes reiserfs, parted, partimage, nmap, w3m, bash, sshd, telnetd, ftpd, and nfsd. It is based on Debians "Sarge" release. LILO, syslinux, isolinux, and GRUB are supported.
The project is evolving more and more into a "Debian on CD" project, which means that its use is not limited to a rescue CD; it is also possible to install a whole Debian system on CD.
Enhancements:
- the cdrecord script was buggy - fixed

tomsrtbt software is "The most GNU/Linux on one floppy disk" for:

- rescue recovery panic & emergencies

- tools to keep in your shirt pockets

- whenever you cant use a hard drive

Tomsrtbt stands for: "Toms floppy which has a root filesystem and is also bootable."

Design goals:

- as much stuff as possible on 1 floppy disk

- keep it self contained, build under itself

- try to make it behave like a normal system

- rescue and recovery functions get priority

KnoppiXMAME is a bootable CD/DVD image with hardware automatic probing and configuration for playing MAME games.

No games are included, but they can be added to the ISO image, as well as new versions of X-MAME, gxmame, and the Linux kernel.

Sentry Firewall CD-ROM is a Linux-based bootable CDROM suitable for use as an inexpensive and easy to maintain firewall, server, or IDS(Intrusion Detection System) Node. The system is designed to be immediately configurable for a variety of different operating environments via a configuration file located on a floppy disk, a local hard drive, and/or a network via HTTP(S), FTP, SFTP, or SCP.
The Sentry Firewall CD is a complete Linux system that runs off of an initial ramdisk, much like a floppy-based system, and a CD. The default kernel is a current 2.4.x series kernel with various Netfilter patches applied. An OpenWall-patched current 2.2.x kernel is also available on the CD.
Booting from the CDROM is a fairly familiar process. The BIOS execs the bootloader(Syslinux) - which then displays a bootprompt and loads the kernel and ramdisk into memory. Once the kernel is running, the ramdisk is then mounted as root(/). At this point our configuration scripts are run(written in perl) that configure the rest of the system. It is the job of these configure scripts to put the various startup and system files into the proper location using either what is declared in the configuration file(sentry.conf) or the system defaults located in the /etc/default directory.
Most of the critical files used at boot time can be replaced with your own copy when declared in the configuration file. This is essentially how we allow the user to configure the system using his/her own configuration and init files.
All of the binaries, files, scripts, etc, used to create the CD-ROM are also available on the CD-ROM. So, with a little practice, you can easily build and customize your own bootable Sentry Firewall CD.

Plan-B is a bootable Linux environment without the need for a hard drive, it runs entirely in ram or from the cd, based on a basic, stripped installation of Red Hat Linux and the fundamental workings of the SuperRescue CD. A list of tools and utilities are also included for projects such as:

* Forensics/Data Recovery
* System/Network Analysis and Security Scanning
* Temporary Network Device/Server
* IDS / NIDS System
* Network Status Report Creation

My reason for its creation came about due to finding other similar projects (SuperRescue CD, Biatchux (F.I.R.E.), Trinux, Knoppix) to be geared toward only a single area of the broad spectrum I was looking for. The first of which (by H. Peter Anvin, the author of Syslinux, Isolinux, and zisofs) was the only one close to the concept I had in mind which is why I chose it as the foundation for this cd. After not finding what I was really looking for, the "All-in-One", I decided the only way to get it was to build one myself.
