Grml is a live system (live CD) based on Debian. It includes a collection of GNU/Linux software especially for system administrators and users of texttools. It provides automatic hardware detection and its default shell is the zsh. You can use it e.g. as a rescue system, for analyzing systems/networks, or as a working environment. It is not necessary to install anything to a hard disk; you don't even need a hard disk to run it. Due to on-the-fly decompression, it includes more than 2 GB of software and documentation on the CD.
Bombardier is a software system that delivers visibility, control, and automation to data center environments. Bombardier provides a means for changes to be rolled out to a network of Linux and Windows servers in a highly controlled way, providing optimum security, logging, and centralized change control.
VanDyke ClientPack is a set of commandline utilities for securely automating file transfer, shell, and public-key administration tasks on Windows, Linux, and Unix platforms. It includes vsftp, an interactive SFTP commandline utility providing quick, easy, and secure file transfer operations, vsh, a commandline shell utility, vcp, a commandline file transfer utility, vkeygen, a public/private key generator utility, and vpka, a commandline tool for uploading keys to a Secure Shell server.
The sniffy project can trace/log the data of any pseudo terminal in the system. Due to the way the terminal works, such a terminal trace provides complete information of what happened on the terminal screen, and sniffy is able to display/replay this information. It consists of a kernel module able to connect/hook on the pseudo terminal, a program to display the contents of any pseudo terminal on the fly, a daemon process tracing the pseudo terminal content into the file, and a replay program to replay any stored pseudo terminal session.
Plash is a sandbox for running GNU/Linux programs with minimum privileges. It is suitable for running both command line and GUI programs. It can dynamically grant Gtk-based GUI applications access rights to individual files that you want to open or edit. This happens transparently through the Open/Save file chooser dialog box, by replacing GtkFileChooserDialog. Plash virtualizes the file namespace and provides per-process/per-sandbox namespaces. It can grant processes read-only or read-write access to specific files and directories, mapped at any point in the filesystem namespace. It does not require modifications to the Linux kernel.
Iron Bars SHell is a restricted Unix shell. The user can not step out of, nor access, files outside the home directory. Two ASCII configuration files are used for more control. The system administrator can define which commands may be executed by the user. No other executables are allowed. The admin also has the opportunity to define what kind of files the user may create. If a file has a certain extension (such as .mp3, .c, etc.), ibsh automatically erases it.
Hardened Debian improves Debian GNU/Linux with high security and hardening features, hardened kernels and packages, DHKP, and other security related enhancements. It makes systems more difficult to compromise using common attacks such as race conditions, chroot jail escapes, and buffer overflows.
