The PCI Utilities package contains various utilities dealing with the PCI bus, and also a library for portable access to PCI configuration registers. It includes `lspci' for listing all PCI devices (very useful for debugging of both kernel and device drivers) and `setpci' for manual configuration of PCI devices.
The ht://Dig system is a complete WWW indexing and searching system for a domain or intranet. This system is not meant to replace the need for internet-wide search systems like Lycos, Infoseek, Google, and AltaVista. Instead, it is meant to cover the search needs for a single company, campus, or even a particular sub-section of a Web site.
mon is a tool for monitoring the availability of services and sending alerts on prescribed events. Services are defined as anything tested by a "monitor" program, which can be something as simple as pinging a system, or as complex as analyzing the results of an application-level transaction. Alerts are actions such as sending email, making submissions to ticketing systems, or triggering resource fail-over in a high-availability cluster.
Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications.

The console-tools package allows you to set-up and manipulate the Linux console (ie. text screen and keyboard), and manipulate console-font files. It was developed from version 0.94 of the standard `kbd' package, and integrates many fixes and enhancements, including new kbd features up to 0.99.
Python is an interpreted, interactive, object-oriented programming language. It combines remarkable power with very clear syntax, and isn't difficult to learn. It has modules, classes, exceptions, very high level data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems (Tk, Mac, MFC, GTK+, Qt, wxWindows). New built-in modules are easily written in C or C++. Python is also usable as an extension language for applications that need a programmable interface.
Tenable Nessus is a world-leader in active vulnerability scanners. It features high-speed discovery, configuration auditing, asset profiling, sensitive data discovery, and vulnerability analysis of your security posture. Nessus scanners may be distributed throughout an entire enterprise, inside DMZs, and across physically separate networks. It is free of charge for personal use in a non-enterprise environment.
SANE stands for "Scanner Access Now Easy" and is an application programming interface (API) that provides standardized access to any raster image scanner hardware (flatbed scanner, handheld scanner, video and still cameras, framegrabbers, etc.). The SANE standard is public domain and its discussion and development are open to everybody. The source code is written for UNIX (including Linux) and is available under the GPL, but commercial applications and backends are welcome. The package contains the libraries, net support, and scanimage. The X frontends xscanimage and xcam can be found in sane-frontends.
