rpm livelinuxcd is a set of ISO images and a toolkit. The first CD image is a basic live CD with X/KDE, GNOME, twm, VPN/DSL, kickstart, and other tools based on RPM packages. The second CD image includes a server with ssh, Apache, PHP, MySQL, Samba, Squid, and more, but without X11. The toolkit consists of shell scripts to create new CDs from RPM package lists or comps files.
PLD RescueCD is a bootable disk that contains a live Linux distribution based on PLD Linux x86 and x86-64. It uses transparent xz compression to fit about 180 MB of software onto a single mini CD in a usable form. It can be used to rescue ailing machines, perform intrusion post-mortems, or act as a temporary secure Linux-based workstation. It is possible to boot via PXE and from USB devices.
alcolix is a minimal Linux rescue distribution with the goals of being small, compatible, and very usable. It has a cozy shell and a multitude of partition rescue/editing tools, all based on up-to-date releases (e.g., 2.4.x kernel with USB support). It uses cpio.bz2 data disks and has a full GRUB bootloader, memtest86, and more.
Salvare (from the Latin "to rescue") is a small Linux distribution designed for small, credit-card sized CDs which typically hold around 34MB. More Linux than tomsrtbt but less than Knoppix, it aims to provide a useful workstation as well as a rescue disk. In addition to providing a rescue environment similart to tomsrtbt, it adds OpenSSH, a graphical and text mode Web browser (Links), security tools such as chkrootkit, nmap, and tcpdump, the ability to apt-get install additional software from Debian into tmpfs, the ability to run entirely from RAM, and much more. It's also customizable using a simple source-code based package management system.
ThePacketMaster Linux Security Server is a CD-based security auditing tool that boots and runs penetration testing and forensic analysis tools. It is handy for security auditors. Some tools included are nessus, ethereal, The Coroner's Toolkit, chntpw, and minicom. It includes modules for any Linux 2.4.20 SCSI driver.
Thinux is a thin-client server on a live CD. It boots a network of diskless computers to automatically start an application such as a Web browser. Each thin client machine acts as a cluster node to share its processing and memory resources with each other to take the load off the server. It is a turnkey solution that does not change nor rely on your existing systems to run. By booting from a removable CD, it does not lock-in the user so it is convenient to test. It is ideal for any organizations that require large deployment of software automatically and cost effectively.
