FrazierWall Linux is a single floppy distribution Linux firewall that is based on the Linux Router Project. It is designed for use with ethernet base internet connections (such as cable modems or xDSL lines). It allows you to share such a connection with several other computers on a LAN. It is easy to setup and maintain, and is available in a Linux configurable software version.
glogin is a program that can be used to cause a terminal (usually a virtual console) to be logged in automatically, without having to type a userid and password. Stick it in place of getty in /etc/inittab to have terminals come up logged in and at a shell prompt at every boot. Same purpose as 'alogin', but you use it a little differently, and it does a little more of the usual login stuff. It is a simple Perl program, and can be easily customized.
sash-plus-patches is a collection of patches for the well known standalone shell, sash. The key features are the chroot, pivot_root, and losetup functions. These functions provide interfaces to the respective Linux system calls. They are especially useful when sash is used in a initial ramdisk ("initrd") environment. In addition, simple shell variable expansion support has been added.
Ficl (Forth inspired command language) is an ANS Forth interpreter written in C. Unlike traditional Forths, this interpreter is designed to be embedded into other systems as a command/macro/development prototype language. Ficl provides object extensions that can be used to wrap methods and structures of the host system without altering them.
