footprint is a tool that makes it easier to create and manage kickstart files. It allows you to define systems, create profiles for systems, and macros per distribution. It can create kickstart files on the fly, make custom initrd (ramdisks), create custom bootfloppies, and can manage your DHCP and PXE configuration.
Instant-Grid is a Knoppix-based live-CD bundled with a pre-configured grid environment based on the Globus Toolkit. One PC started from this CD becomes the Instant-Grid frontend. It also functions as a PXE boot-server, allowing other PCs in the same local network to boot the Instant-Grid environment. Together with the frontend, these PCs automatically form a working test grid. Like with the original Knoppix, the existing configuration of the participating PC is not touched (except maybe for enabling the PXE boot-option), and remains instantly available by a simple reboot.
OpenVPS is a set of software built on top of the Linux VServer aimed specifically at Web Hosting. It is not another set of kernel patches, but a set of scripts to create virtual servers, collect resource utilization information, and provide an interface to the customer as well as the administrator.
Omnitty is a curses-based program that allows you to log into several machines simultaneously and interact with them, selectively directing input to individual machines or groups of selected machines. You can run both line-oriented and screen-oriented in the target machines, because it has built- in terminal emulation capability. When the window is large enough, Omnitty also displays a "summary area" for each machine, in which it shows what the latest output from the machine was, so you can have an idea of what is going on in each machine.
xml2hostconf generates RPM packages, dhcpd.conf, pxelinux files, kickstart files, and HTML documentation with XSLT. It is a framework for central configuration and automatic installation of a Fedora/Redhat Linux network. Configuration files get shipped to the client computers by generated RPMs.
Thinux is a thin-client server on a live CD. It boots a network of diskless computers to automatically start an application such as a Web browser. Each thin client machine acts as a cluster node to share its processing and memory resources with each other to take the load off the server. It is a turnkey solution that does not change nor rely on your existing systems to run. By booting from a removable CD, it does not lock-in the user so it is convenient to test. It is ideal for any organizations that require large deployment of software automatically and cost effectively.
