Syslinux is a collection of boot loaders for Linux and other operating systems which operates on Linux ext2/ext3 filesystems, MS-DOS FAT filesystems, network servers using PXE firmware, or from CD-ROMs. Syslinux has an advanced extension API and contains two optional menu systems. It also includes MEMDISK, a tool for booting legacy operating systems from non-traditional media like PXE or CD-ROM.
TFTP Server is a multi-threaded TFTP server, allowing any number of clients to connect simultaneously. It supports tsize, blksize, and interval options, PXE boot, and can be run standalone or as a daemon. Port ranges can be specified to work across firewalls. There is also a single port version, for situations where additional ports cannot be opened.
The Linux Bootdisk HOWTO describes how to design and build boot/root diskettes for Linux on the Intel platform. These disks can be used as rescue disks or to test new system components. You should be reasonably familiar with system administration tasks before attempting to build a bootdisk.
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.
TrinityOS is a step-by-step, example-driven HOWTO on building a very functional Linux box with strong security in mind. TrinityOS is well known for its strong packet firewall ruleset, Chrooted and Split DNS (v9 and v8), secured Sendmail (8.x), Linux PPTP, Serial consoles and Reverse TELNET, DHCPd, SSHd, UPSes, system performance tuning, the automated TrinityOS-Security implementation scripts, and much more.
UPX is a portable, extendable, high-performance executable packer for several different executable formats. It achieves an excellent compression ratio and offers very fast decompression. Your executables suffer no memory overhead or other drawbacks. UPX supports vmlinuz/386, linux/elf386, linux/386, win32/pe, dos/exe, djgpp2/coff, and many more.
WrapLinux is a utility to wrap a Linux kernel, together with a kernel command line and one or more initrd/initramfs files into a single file in ELF or NBI format. This is required by certain boot protocols, such as Etherboot/Netboot, and may otherwise be desired for consistency reasons. It can be considered a replacement for the mknbi and mkelf utilities.
