The Event monitor project is an approach to network management based on message passing between manager and managed nodes. It's based on a client/server platform, where the server is the manager node, and all clients are managed nodes. This tool is under development, but has lots of features implemented, like a graphical console, message passing layer, one disk monitor and clients for sending messages (both API and binary forms are provided).
game control program helps you administrate gameservers (it's written for Q1 and Q3, but works for others). It is highly modular and therefore extensible. With the current modules, it can start/stop servers, create and rotate logfiles, allow remote administration via telnet, and kick misbehaving players automagically (according to a rule set).
mfind is an extensible Machine Find utility. In any network of more than 10 machines, it sometimes becomes necessary to get a list of which machines meet some criteria. This utility is one possible answer to this problem. Composed of two applications, mfind creates a database of machine configurations which is easily parsable using wildcards and regular expressions. For example, it makes it rather easy to determine just how many Sun systems with 256MB of RAM running Solaris 2.6 and an ATI-VideoXpression video card are on-site.
Nets is a flexible and extensible network inventory and asset management system that works on all Unix and Windows platforms, and works with most SQL databases.

It assists in provisioning, costing, reporting, and maintaining network details. It includes a network browser, an extension API, and plugins for IP address map visualisation, reports, schematics.
