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.
scponly is an alternative "shell" of sorts for system administrators who would like to provide access to remote users to both read and write local files without providing any remote execution priviledges. Functionally, it is a wrapper around the ssh suite of applications. It is typically used by creating a user whose shell is set to scponly. This user can neither login interactively nor execute commands remotely, but it can use scp and sftp to download and upload files to the computer, governed by the usual Unix file permissions.
Seccheck is a feature rich, modular, host-level security checker for Solaris 10. Easily expandable with customised modules, Seccheck produces highly detailed reports based around known and published security best-practices and guidelines. It also produces recommendations on how to fix flagged security issues.
Slackselect is a package manager for Slackware that can install, remove, and upgrade packages. It can install/upgrade packages from FTP/HTTP and CD sets. It scans your installed packages, and can show you the packages that can be upgraded (and do it for you). It also finds obsolete packages that aren't in the distribution anymore. It was inspired by the functionality of dselect.
spill manages symbolic links under one tree which point to matching filenames in another. When individual projects are configured with project/version-specific -- prefix= settings, to keep their installations segregated, spill can make them appear to be installed in a common place, e.g. under /usr/local. It can also delete the links associated with a particular program. It is similar in concept to various other programs such as stow, depot, and relink. However, it's written in C, so it isn't reliant on an interpreter being available. It also doesn't assume complete control of the directory tree where the symbolic links are created. It can create both absolute or relative symbolic links, the latter being more convenient in some setups.
