Raven's System Stats allows users to collect detailed information about an operating system, including kernel architecture, distro, operating system, kernel version, glibc version, name of login shell, number of CPUs, CPU description, hyperthreading support, CPU MHz, CPU cache, bogomips, used and total RAM, used and total swap, filesystem size and type, uptime, unique users logged in, total login shells, currently running processes, total processes since bootup, load average, X resolution, and the number of X servers running.
Oculus Server Monitor uses a plain text, human readable protocol to export server information to any client that connects to it. It supports a plugin system for commands, an XML-style configuration file, and IP-based access control. Odie, the Oculus Daemon InterfeacE, is a rich Web application that polls a list of hosts for their status.
dietsniff is a tiny tool for analyzing traffic on a network. It's not intended to replace well-known tools like tcpdump or ethereal. It's intended for the case when a small and especially static sniffer is required. Accordingly, it's also by far not that powerful, and is also bound to Linux as a platform. While it doesn't use or need the libpcap, it produces pcap-logs that can be analyzed by more sophisticated tools like tcpdump or Ethereal.
NCmatrix is a ncurses-based screensaver that produces the familiar display of vertical characters with added functionality to display network traffic. /proc/net/dev is polled to grab incoming and outgoing packet information, and the results are displayed as long or short colored streams of characters in the display, depending on the number of packets transferred since the previous poll. This code is based on the CMatrix codebase by Chris Allegretta.
The RegLookup project is devoted to direct analysis of Windows NT-based registry files. RegLookup provides command line tools, a C API, and a Python module for accessing registry data structures. The project has a focus on providing tools for digital forensic examiners (though it is useful for many purposes), and includes algorithms for retrieving deleted data structures from registry hives.
Libsmbios is a cross-platform library intended to be used to obtain common information available in a BIOS. Major features include the ability to update the BIOS on Dell systems (in conjunction with the Dell RBU Linux kernel driver), programmatic access to information in SMBIOS tables, and the ability to obtain Dell system-specific information such as the Dell System ID number, service tag, and asset tag. Future plans include APIs for $PIR and mptable mapping. There is a C API for some of the more commonly used functions, and example binaries to show off most of the facilities.
JSTUN is a STUN (Simple Traversal of UDP (User Datagram Protocol) through NAT (Network Address Translation)) implementation. STUN provides a means for applications to discover the presence and type of firewalls or NATs between them and the public Internet. In the presence of a NAT, STUN can also be used by applications to learn the public Internet Protocol (IP) address assigned to the NAT.
Mail ConfiGuru is a standalone cross-platform tool and library that displays the configuration of email clients available to the currently logged-in user. It provides one interface to the settings of all supported email clients, which currently includes Mozilla Thunderbird, Mozilla Mail (SeaMonkey), MS Outlook, MS Outlook Express, KMail, and Ximian Evolution.
