Argus is a generic IP network transaction auditing tool that has been used by thousands of sites to perform a number of powerful network management tasks that are currently not possible using commercial network management tools. Argus runs as an application level daemon, promiscuously reading network datagrams from a specified interface, and generates network traffic audit records for the network activity that it encounters. It is the way that Argus categorizes and reports on network activity that makes this tool unique and powerful.

NagTail is like tail(1), but for the nagios status.dat file.

This is a plugin package for Nagios. Quoting from the main Nagios package: Nagios is a host and service monitor designed to inform you of network problems before your clients, end-users or managers do. It has been designed to run under the Linux operating system, but works fine under most *NIX variants as well. The monitoring daemon runs intermittent checks on hosts and services you specify using external "plugins" which return status information to Nagios. When problems are encountered, the daemon can send notifications out to administrative contacts in a variety of different ways (email, instant message, SMS, etc.). Current status information, historical logs, and reports can all be accessed via a web browser.

Aircrack-ng is an 802.11 WEP and WPA-PSK keys cracking program that can recover keys once enough data packets have been captured. It implements the standard FMS attack along with some optimizations like KoreK attacks, as well as the all-new PTW attack, thus making the attack much faster compared to other WEP cracking tools. In fact, Aircrack-ng is a set of tools for auditing wireless networks.

To ease the task of network administration, decrease the likelihood of erronous command execution and to maintain all network services from a central point, EnderUNIX SDT anounces the availability of its 9th open-source tool, netUstad. It has been coded in C language and includes its own HTTP server. The newly anounced version provides a web interface for system administrators to add/delete/update FreeBSD IPFW and Linux IpTables rulesets, manage routing table and network interfaces. You can manage your Firewall via a TCP/IP connected remote PC, easily. Project Page:

Icinga 2 is a network monitoring system and parallel development branch to Icinga 1. Written from scratch, it builds on the success of Icinga 1 and deals with shortcomings inherited from Nagios as a fork. Icinga 2 is: - Easy to install with soft link activation of functions and packages - Multithreaded and very fast: Capable of thousands of checks per second - Intuitive to configure, using new object-based, template-driven format - Easy to extend with native support for Livestatus and Graphite - Cluster-enabled for distributed monitoring out of the box

Weathermap is a network visualisation tool, to take data you already have and show you an overview of your network in map form.

PNP is an addon to nagios which analyzes performance data provided by plugins and stores them automatically into RRD-databases (Round Robin Databases, see RRD Tool). During development of PNP we set value on easy installation and little maintenance while running it. An administrator should do other things than configure graphing tools.

rcpd is a RCP server intended specifically for router or network device clients. It is used to transfer configurations, boot images, and kernels images (eg: IOS) to the devices. These files are often tranfered with TFTP, but TFTP has reliability and speed issues and file size limitations due to it's protocol specification and underlying transport; while RCP is not affected.
