The CPAN shell (and module) automates or at least simplifies the building and installation of Perl modules and extensions. It includes some primitive searching capabilities and knows how to use Net::FTP, LWP, and certain external download clients to fetch distributions from the Internet. Then it automatically tests and installs them and their dependencies.
Urpkg is software to install programs in a safe and undoable way. It is able to see what files any given installation command creates, and list and remove them. You are able to restrict the installation command so that it only writes where you allow it to, and does not overwrite files from other packages. Urpkg is especially useful if you want to install programs from source, or create binary packages in an automated way. Under the hood, urpkg creates a user for each package it has to install, which prevents the installation command from run with root privileges. It can be seen as a "command tracer" that remembers what files a command created and prevents it from doing forbidden things. It is written in C but relies on some external commands, like GNU Find.
Fakeroot-ng runs a program while fooling it into thinking it is running with root privileges. When the program does something that only root can do (e.g. create a device file), fakeroot-ng emulates the appropriate system calls so that the program gets a consistent view of its actions. Unlike the original fakeroot, fakeroot-ng uses the ptrace interface, which means that it does not suffer some of the limitations that fakeroot does. In particular, fakeroot-ng supports chroot jails.
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.
PHP Tarbackup is a simple class that allows backing up an entire Web site. It automatically works around timeout limits by splitting the job into multiple requests, allows tarball archive creation and updates, and comes with the Veloce script, which is very useful to automatically unpack tar.gz archives remotely and skip long waiting times due to FTP uploads.
Sisopen is a tool to list and extract the content of SIS files. SIS files are installation files used in Symbian-based smartphones like many S60 Nokia phones. Sisopen is an ANSI-C program, mainly targeted at Linux and other Unix-like systems. It can be compiled on almost every system with a C compiler and zlib. Sisopen fully understand the SIS file format and is able to show conditionals, installation-time options, and much information about the SIS file, not just the file names.
A.M.I.C.U.S. (Automatic Multimedia Installation Configuration Utility System) helps users quickly and easily install and configure MythTV on generic PC hardware. It uses the Debian Netinst CD to install GNU/Linux and just the required packages to allow a functional MythTV on low end hardware.
