Fast Track Systems Monitor (FTMON) is a monitoring engine that can be integrated with other systems management vendor solutions. It also defines a standard that allows applications/devices to be instrumented rapidly. The intent is to allow writing an FTMON monitor for virtually every device or application, and that any detected problems from these monitors will be able to be forwarded to any systems management solution. It is currently completely configuration file based.
aircrack-ng is a set of tools for auditing wireless networks. It's an enhanced/reborn version of aircrack. It consists of airodump (an 802.11 packet capture program), aireplay (an 802.11 packet injection program), aircrack (static WEP and WPA-PSK cracking), airdecap (decrypts WEP/WPA capture files), and some tools to handle capture files (merge, convert, etc.).
ntopmg is a network probe that shows network usage in a way similar to what top does for processes. It acts as a Web server, creating an HTML dump of the network status. It sports a flow collector, an HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics. Its C++ core can be scripted in Lua, for changing the appearance and extending functionality.
JarBuilder allows programmers to easily create jar files. It is written in Java, providing a nice Swing GUI. Although it isn't programmed as a classic wizard, Java programmers are able to build their own jar files with JarBuilder in three steps. First, you selected the files you want to include in the jar file, then you load or write your manifest file (JarBuilder can do an automatic search for main classes for you and add the correct statement to the manifest file). Finally, you select the compression level of the jar file, and JarBuilder creates the file for you.
VerliHub is a Direct Connect server (HUB) for Linux. It features banlists for IP addresses, nicks, and hosts, temporary or permanent bans, the ability to register users for a hierarchy of 2 non-op and 4 opertor levels, MySQL data storage, and the ability to change some settings at runtime. It consumes minimal CPU resources and quite moderate RAM resources. Users that are registered for a VerliHub server gain a few advantages. For example, the user won't be affected by an IP address ban that was set against another user who shares the same IP address.
yaspi (Yosi's Anti-Spam POP3 fIlter bot) is a POP3 mail-scanner specifically made to combat mail bombings caused by viruses (i.e. Swen). It connects to the POP3 server, inspects the messages, and deletes the infected ones without ever downloading them. Its most interesting feature is that it can automatically send abuse reports to the ISPs from which the infected mails originated.
DansTuner is a program to tell you if you are playing a pitch in tune. Major features include automatic discovery of which note you are trying to play (good for trumpet, singer, etc.), the ability to play a guide tone at a configurable volume, a graphical moving "needle" with a red/green display and detail about how flat or sharp you are, and an easily configurable background noise threshold.
