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).
Hamster Font Manager (HFM) helps you control the avaliability of fonts in all of the supported applications from a central place. It includes modules to support X11, Ghostscript, and TeX. A PostScript module handles PS Fonts while other fonts remain untouched by this program. It features a nice Tcl/TK GUI. For X11 configuration to work, this software has to run on the machine's own X Server.
Moodss is a modular monitoring application, which supports operating systems (Linux, UNIX, Windows, etc.), databases (MySQL, Oracle, PostgreSQL, DB2, ODBC, etc.), networking (SNMP, Apache, etc.), and any device or process for which a module can be developed (in Tcl, Python, Perl, Java, and C). An intuitive GUI with full drag'n'drop support allows the construction of dashboards with graphs, pie charts, etc., while the thresholds functionality includes emails and user defined scripts. Monitored data can be archived in a SQL database by both the GUI and the companion daemon, so that complete history over time can be made available from Web pages or common spreadsheet software. It can even be used for future behavior prediction or capacity planning, from the included predictor tool, based on powerful statistical methods and artificial neural networks.
pkgusage lists all the packages you have installed on your system, along with a number telling you how many days ago you last accessed any of the files in the package. This could be useful for cleaning out your hard drive. Pkgusage works with RPMs and Debian packages, and is written to be easily portable to other package managers as well.
MailStripper Pro is a mail scanner that aims to remove spam and viruses from incoming mail. It recognises and decodes many obfuscation techniques used by spammers and uses several different mechanisms to recognise spam which are immune to Bayes poisoning, and has achieved real-world success of over 99.8%. It is MTA-independent and does not implant itself into your mail server. Instead, it functions as a proxy, allowing the MTA to reside on a different server.
