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.

It communicates via simple TCP-based messages, and is written in Perl.
The Toby intrusion detection system is a fairly complete reimplementation of tripwire-1.3 (ASR) into Perl. It mainains a database of file properties to detect alterations to those properties.
