StableNet Express can comprehensively monitor an entire network, including the system and application environments. It features an easy-to-follow graphical display which provides a live view of what is going on in a networked IT system. The automatic discovery functions allow the entire monitoring system to be up-and-running within only a few minutes. Nothing needs to be installed on the production systems. It can be extended by users with their own measurement and alarm modules by adding scripts into a specific folder.
Spoink is an output plugin for snort that works by blocking access to attackers using OpenBSD's pf API. Spoink uses a pf table and a blocking rule to stop "attackers" from accessing your system. To protect from false negatives you must have a whitelist full of IP addresses. It only blocks attacks defined in snort rules.
Dbeacon is a distributed multicast monitoring tool. The main purpose of a beacon is to monitor other beacons' reachability and to collect statistics such as loss, delay, and jitter between beacons. Dbeacon supports both IPv4 and IPv6 multicast and supports collecting information using both Any Source Multicast (ASM) and Source-Specific Multicast (SSM).
gbox_applet is a GNOME applet which monitors several mbox-type mailbox files. Each mailbox can be assigned to a priority between 0 and 2 and it can have its own time interval for checking. For each priority there is a different icon. gbox can also count the mail in the boxes and show the subject/sender of each mail in the applet's menu. A tooltip shows a summary of the information in three different kinds.
Remote Methode Call is a project to enable calls to methods in remote C++ classes. The transport is implemented as a library, and is free from dealing with the internal RMC stuff, so any C/C++ programmer is able to write a transport for his own purpose. RMC(2) currently has a sockets transport library as reference implementation. It is developed on Linux, and supports Linux on iX86 and PPC. RMC should also work on BeOS. Testers and developers are welcome to the project.
