The 64 Studio Platform Development Kit (PDK) is a version control system for GNU/Linux distributions, allowing the creation and management of many different projects, based on Debian and Ubuntu sources. PDK is written in Python, and the source code is well commented and contains documented examples.
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.
MrTools is a suite of tools for managing large, distributed environments. It can be used to execute scripts on multiple remote hosts without prior installation, copy of a file or directory to multiple hosts as efficiently as possible in a relatively secure way, and collect a copy of a file or directory from multiple hosts.
DrProject is a Web-based software project management portal that integrates a revision history viewer with issue tracking, mailing list management, a wiki, and other features. It is not a learning management system; instead, it is designed to introduce students to the tools that professional development teams use to coordinate their work. Unlike its industrial-strength cousins, SourceForge and CollabNet, DrProject is easy to install and administer. It has a very simple interface: students can learn all of its features in less than an hour. It provides a scripting interface that can be used to automate bulk or repetitive tasks.
slackroll is a package or upgrade manager for Slackware Linux. It is designed to work with official mirrors in systems mainly composed of official packages with a few unofficial packages. It lets you automatically upgrade or install packages, and displays which packages have been added or removed from the Slackware tree.
Virt-Factory is a framework for managing a large number of Xen virtual machines, such as might be found in data centers or large lab configurations. It works by managing a pool of registered physical hosts and then deploying virtual machines, which have specific roles as defined by their "profiles" (profiles act as shareable virtual appliance definitions), onto those hosts. Virt-Factory provides both a Web UI (for ease of use) and an XML-RPC API (for scripting of admin actions). A command line interface (along with other advanced batch management features) is coming soon.
Cobbler is a network installation and update server. It can be used to automatically set up PXE, install virtual guests, manage answer files, and reinstall existing Linux machines. Advanced features include importing distributions from DVDs and rsync mirrors, kickstart templating, integrated yum mirroring (integrated with the installer to make updates available at install time), creation of netboot ISOs, and built-in DHCP/DNS Management. Tools such as "cobbler triggers", a Python API, and an XMLRPC API allow integration with cobbler with the rest of your datacenter environment or other systems management applications. There is also a Web interface to simplify management of the install server. Cobbler supports RHEL 4+, Fedora, and derivative distributions, and is also able to install other popular distributions.
