SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers, but due to its simplicity and small size can be used on embedded devices as well. It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Monitorix includes its own HTTP server built in (which is listening by default on port 8080/TCP) to see the statistics graphs, so you aren't forced to install a third-party web server to use it. Just point your browser at http://localhost:8080/monitorix.

A software toolkit for using the EPCglobal Low Level Reader Protocol (LLRP) to communicate with conforming RFID readers.

Switchmap is a Perl program that creates HTML pages that show information about a set of Ethernet switches. It uses SNMP to gather data from the switches. Samples of Switchmap output can be found on the Project home page.

BASE is the Basic Analysis and Security Engine. It is based on the code from the Analysis Console for Intrusion Databases (ACID) project. This application provides a web front-end to query and analyze the alerts coming from a SNORT IDS system.

Enables tunneling of network connections through restrictive HTTP proxies. Features: Portmapping, SOCKS4, SOCKS5, web-based admin interface, possibility to use standalone server (perl) or hosted server (PHP), optional authorization from LDAP or MySQL

Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. It is designed to be very plug-and-play. A default installation provides a lot of graphs with almost no work. In Norse mythology, Hugin and Munin are the ravens of the god king Odin. They flew all over Midgard for him, seeing and remembering, and later telling him. "Munin" means "memory".

lua-resty-waf is a web application firewall implemented in Lua for OpenResty/NGINX, designed to run inline at the edge with low overhead. It inspects requests and responses during NGINX phases, applying rule logic and anomaly scoring to detect patterns like SQL injection, cross-site scripting, and protocol abuse. Rules are organized into policies with configurable actions—block, log, or allow—and can leverage shared dictionaries for counters, rate limits, and caching decisions. Because it runs inside the NGINX event loop, it scales with the web tier and avoids the latency of external proxies. Operators can extend it with custom Lua code, integrate threat feeds, or adapt it to application-specific quirks without recompiling modules. The result is a flexible, scriptable WAF that pairs the performance of NGINX with the expressiveness of Lua for nuanced HTTP defense.

Ddclient is a Perl client used to update dynamic DNS entries for accounts on 'Dynamic DNS Network Services' free DNS service. It currently supports a lot of different routers and a few different services. The project moved to github. See https://www.github.com/ddclient/ddclient for support.

NeDi is a lightwheight network management framework, which is based on a scheduled discovery, a SQL backend and a web based user interface.

Netdeep Secure is a Linux distribution with focus on network security. Is a Next Generation Open Source Firewall, which provides virtually all perimeter security features that your company may need. It offers Web content filters, ensuring better performance of the network, allowing users to use the service efficiently and securely, providing a deep control of the use of the Web access service, blocking access to unwanted websites, Virus, Spam, Applications and intrusion attempts. Its configuration is made entirely by the web interface.

WebInject is a tool for automated testing of web applications and web services. It can be used to test system components with HTTP interfaces, as a test harness to create a suite of functional and regression tests, or for service-level monitoring.

Cricket is a high performance, extremely flexible system for monitoring trends in time-series data. Cricket was expressly developed to help network managers visualize and understand the traffic on their networks, but it can be used all kinds of other job

FlowViewer provides a convenient web-based user interface to Mark Fullmer’s flow-tools suite and CMU's netflow data capture/analyzer, SiLK. The inclusion of the underlying SiLK tool set enables FlowViewer users to continue to use the tool with the newer IPFIX netflow data protocol, which includes support for IPv6 and Cisco's v9 and FNF netflow. FlowViewer has been developed for NASA’s Earth Sciences Data and Information System (ESDIS) networks, and credit goes to NASA for their usual outstanding support of innovation. The FlowViewer tools provide additional graphing and tracking features by utilizing open source software including Thomas Boutrell’s gd, Lincoln Stein's GD, Martien Verbruggen's GD::Graph, and Tobias Oetiker’s RRDtool. FlowViewer v4.6 fixes non-UTC local time environments for FlowViewer and FlowGrapher, and $no_devices_or_exporters FlowMonitor_Collector problem. **Note: SiLK must be v3.8.0 or later. Version 3.9 handles sFlow data.
