TinyIDS is a distributed intrusion detection system (IDS) for Unix systems. It is based on the client/server architecture and has been developed with security in mind. The client, tinyids, collects information from the local system by running its collector backends. The collected information may include anything, from file contents to file metadata or even the output of system commands. The client passes all this data through a hashing algorithm and a unique checksum (hash) is calculated. This hash is then sent to one or more TinyIDS servers (tinyidsd), where it is compared with a hash that had previously been stored in the databases of those remote servers for this specific client. A response indicating the result of the hash comparison is finally sent back to the client. Management of the remotely stored hash is possible through the client's command line interface. Communication between the client and the server can be encrypted using RSA public key infrastructure (PKI).
Membrane SOAP Router is a modular SOAP intermediary written in Java. It is fully configurable due to Spring style configuration. You can audit SOAP traffic, route messages through DMZ, and gather performance statistics. The small memory consumption of less than 20 Megabytes makes it possible to run an instance of Membrane SOAP Monitor on any computer that provides or consumes Web services.
jmxsh is a fully scriptable command-line JMX client based on Tcl. It is simply a Tcl interpreter powered by Java/Tcl (with command-line history and editing provided by JLine) that has special command-line options for connecting to JMX servers and special Tcl commands for interacting with JMX servers. jmxsh is capable of simultaneously connecting to multiple JMX servers. There's also a "browse mode" for exploring the remote JMX namespace without knowing beforehand the names of MBeans or their properties. jmxsh and all its dependencies are distributed in a self-contained executable jar file for ease of use.
The WebReboot Plugin for Nagios is a suite of commands that can be used within Nagios to monitor a server and take corrective action if necessary via the WebReboot line of products. For example, the plugin can be used to alert you if a host is powered down, versus simply not responding to network requests. Likewise, it can be used to reboot a server if a host fails to respond to ping, or to shut down a server when a critical temperature threshold is exceeded. The commands can be mixed-and-matched with all existing Nagios commands, maximizing total network coverage.
Keywatch is a free, OSGi-based monitoring system that provides the adaptability of a modern monitoring system without being complex or hard to configure. It support agents written in any language, and comes pre-packed with a Perl agent and a set of check scripts. Keywatch also supports Nagios check scripts.
Wiseman is an implementation of the WS-Management specification for the Java SE platform. The project scope includes the WS-Management specification and its dependent specifications, which can be found at http://www.dmtf.org/standards/wbem/wsman/. The project requires Java SE 5+ or above, and is built on JAXB 2.0 and SAAJ 1.3 (part of the JAX-WS project). Ant scripts for standalone and Netbeans builds are supplied.
