bcnu is a Web-based system management tool which delivers information on the status of networked systems in a simple and easy-to-use manner. It uses a web browser to display information about hosts in a tabular form. Historical information can be held indefinitely, and there is a powerful query tool available to interrogate it. Client systems can run an agent which logs information back to a central system. An agent scheduler is integrated to allow agents to be run at different intervals. Standard agents include ftp, http, disk space, logfiles, processes, and more.
Big Brother is a combination of monitoring methods. Unlike SNMP where information is just collected and devices polled, Big Brother is designed in such a way that each local system broadcasts its own information to a central location. Simultaneously, Big Brother also polls all networked systems from a central location. This creates a highly efficient and redundant method for proactive network monitoring.
DansGuardian is a Web content filtering proxy that uses Squid to do all the fetching. It filters using multiple methods including, but not limited to, phrase matching, file extension matching, MIME type matching, PICS filtering, and URL/domain blocking. It has the ability to switch off filtering by certain criteria including username, domain name, source IP, etc. The configurable logging produces a log in an easy to read format. It has the option to only log text-based pages, thus significantly reducing redundant information (such as every image on a page).
MAT is an easy-to-use network-enabled UNIX configuration and monitoring tool. It provides an integrated tool for many common system administration tasks, including backups, replication, and running commands on hundreds of machines at once. It includes a warning system for potential system problems, and graphing of many common system parameters. MAT provides many of the tools a system administrator needs during the day, including DNS, NIS, Backups, and Replication. One can run a MAT command on many hosts at once. A simple editor window is provided which can modify a set of machine's configurations in one session.
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. Its complete GUI allows you to maintain details of your entire network, from network links down to interfaces and routers. 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.
PIKT is cross-categorical, multi-purpose software for monitoring and configuring computer systems, administering networks, organizing system security, and much more. PIKT is intended primarily for system monitoring, and secondarily for configuration management, but its versatility and extensibility evoke many other wide-ranging uses. PIKT consists of a sophisticated, feature-rich file preprocessor; an innovative scripting language with unique labor-saving features; a flexible, centrally directed process scheduler; a customizing file installer; a collection of powerful command-line extensions; and other useful tools.
popexec is a program for Unix/Linux which checks a POP e-mail account and then runs a program whenever new e-mail arrives. It can also optionally run a program when it sees that you no longer have new e-mail in your POP box. Examples are included which show you how to: Write "You have mail" or "You have X new messages" to a terminal, make a terminal beep, play an audio file, pop an X window onto the screen, make your keyboard LEDs blink, change your desktop background.
