PrEd is a Java-based graphical utility to find and edit Java property files in JAR, WAR, and other kinds of ZIP archives. It is an appropriate tool for customizing Java applications which use XML and Property files for their configuration. It provides an interface to edit the property values of property files and to edit the values of XML text nodes and attributes. No knowledge of XML is needed to edit XML files. The program can update JAR and WAR files without having to extract them.
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.
FREP is an application which can be used to keep files in a cluster of servers synchronized from a centralized location. Under the hood, it uses the Spread toolkit (broadcast/multicast traffic), libevent/epoll, sendfile, inotify, intelligent file transfers using the generic diff format, and zlib compression.
breloc does binary edits on files to relocate compiled-in prefixes, padding with extra slashes to make up for differences in the length of the prefixes. In order for breloc to be most effective, a binary package should be configured with a prefix that has a lot of extra slashes at the end of it. beloc is distributed as part of the nsbd package, but it is also quite useful independently.
Pocket Linux is an almost minimal, one floppy linux system designed to quickly convert PC workstation into secure linux-based workstation using ssh to connect to remote host (other networking clients are also supported). It supports bootp for determining host IP and other network parameters (there's also manual configuration possible, but bootp is recommended). In addition to workstations equipped with a network card (ethernet or arcnet), you can also use Pocket Linux on a PC equipped with a modem. Modem is automatically detected and then PPP connection is made.
RACE (Remote Administration in distributed Computing Environments) is a library framework (and will be a set of applications) to aid the system administrator in deploying software and configuration updates to a large number of client computers. The administrator can easily treat intercommunities and respect differences between the individual computers. RACE uses RPM for package management, but it is designed to be easily extended for other package managers.
