m23 is a software deployment system for Debian GNU/Linux that allows you to install and administrate hundreds of clients via network. It can partition and format clients and install Debian, (K/X)Ubuntu, Linux Mint, Fedora, OpenSuse, and CentOS operating systems on your virtual and physical clients. Group functions allow the comfortable update and installation of further packages during operation. Mass installation functions simplify your administration chores. m23 has a Web interface. Backup functions are implemented for server and clients.
Dpsyco is a automated system to distribute system configurations to several computers. It is written mainly for the Debian distribution but should be portable (without too much difficulties) to other distributions or Unixes as well. It consists of a number of shell scripts to perform the desired actions. With it you can handle users, add ssh-public-keys, patch the system, update things using cfengine, install files (overriding other package files), and more.
C3 Power Tools are a set of Python scripts that ease the use and maintenance of single and multiple clusters. Of the seven core tools, only two are restricted to root use. The C3 tools stand out from similar cluster tools in that they transparently support multiple clusters as easily as a single cluster. These tools are so flexible that they can also be used on groups of workstations not configured as a cluster.
p-run is a utility that runs a program, script, or series of commands on a large number of hosts in parallel. It simplifies management of machines in computer labs. It uses ssh, and supports password and key-based authentication. p-run uses libexpect, and will run in parallel across as many processes as specified. When run on a large number of hosts, its parallel nature significantly speeds up administration.
Moab Grid Suite is a professional grid workload management solution that integrates scheduling, management, monitoring, and reporting of workloads across independent clusters. Moab makes moving to a grid easy by adding grid-optimized job submission and management in a matter of minutes. Moab optimizes data staging and seamlessly integrates with existing security mechanisms or with grid security tool kits such as Globus. It gives sites extensive control over ownership-based access, priority, and service levels. It provides fine-tuned control over the workload and resources to make the grid usable.
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.
DynaStop is a utility to examine IPv4 based addresses for Exim and procmail for the purpose of filtering based upon patterns defined by the administrator. This can be a pivotal factor in email filtering and server load management, since dynamic IP addresses are typically used for dial-up, DHCP, and DSL accounts. All of which have a designated mail exchange server through which all outbound mail flows as defined with many, if not most, large Internet service providers.
