Epylog is a log notifier and parser that periodically tails system logs on Unix systems, parses the output in order to present it in an easily readable format (parsing modules currently exist only for Linux), and mails the final report to the administrator. It can run daily or hourly. Epylog is written specifically for large clusters where many systems log to a single loghost using syslog or syslog-ng.
PyKota is a full featured, internationalized, centralized, and extensible print quota system for CUPS. It supports PostgreSQL, OpenLDAP, MySQL, or SQLite as the quota database backend. This software features most of what you might expect from a modern print quota and accounting solution. Its flexibility and configurability greatly eases its integration into your own computing environment.
Band Saw is a syslog monitoring program for GNOME. It allows the user to define filters that specify which log messages should be drawn to the user's attention. Combined with syslog's remote logging functionality it provides an effective, scalable, and easily deployed monitoring solution.
Hardened Debian improves Debian GNU/Linux with high security and hardening features, hardened kernels and packages, DHKP, and other security related enhancements. It makes systems more difficult to compromise using common attacks such as race conditions, chroot jail escapes, and buffer overflows.
Dconf is a tool to collect a system's hardware and software configuration. It allows you to take your system configuration with you and compare systems (like nodes in a cluster) to troubleshoot hardware or software problems. It can also be configured to send out configuration changes at given intervals to a group of people, or store a new snapshot when system changes happen.
