glFlow is a robust, fast, portable, pcap-centric (D)DoS detection tool.

tcptrace is a tool written by Shawn Ostermann at Ohio University, for analysis of TCP dump files. It can take as input the files produced by several popular packet-capture programs, including tcpdump, snoop, etherpeek, HP Net Metrix, and WinDump. tcptrace can produce several different types of output containing information on each connection seen, such as elapsed time, bytes and segments sent and recieved, retransmissions, round trip times, window advertisements, throughput, and more. It can also produce a number of graphs for further analysis.

Surealived is a effective LVS service tester. It is based on epoll and allows you to detect your hosts state using HTTP, TCP, DNS, exec and a universal LUA embedded tester. SSL is also supported. Testers are easily extendable dynamic modules.

Geo Firewall performs blocking of network traffic based on geography (geo IP), allows to add custom subnets, allows exceptions on ports for incoming traffic for specific geography, keeps visual and persistent logs, shows statistics, automatically updates geographical database.

Access Point Utilites for Unix - it's a set of utilites to configure and monitor Wireless Access Points under Unix using SNMP protocol. Utilites knownly compiles and run under Linux, FreeBSD, NetBSD, OpenBSD, MacOS-X, AIX, QNX.

EHNT is a tool which turns streams of Netflow (version 5) data into something useful and human-readable. (Netflow is a UDP-based traffic reporting protocol created by Cisco, generated by Cisco, Juniper, Foundry, and other routers.)

This is a Host based Intrusion Detection system, it consists of 4 components viz.Port scan detector,Policy Enforcer,Network Statistics,and Vulnerability detector. The backend programs are written in C, the front end is made using Qt Designer and Glade.

IPdump is a tool to generate detailed packet header dumps from packet traces in LBNL's libpcap format (such as generated by tcpdump).

Wireshark plugin for dissecting KNXnet/IP packages

LAN-MANAGER is an application which will be able to monitor networks,to analyze the network's topology and warn the network's administrator in case of an incident.

wdiag - a collection of utilities to get DSL stats from Westell DSL modems. It is written in C and and should work on Linux 2.4/2.6 and FreeBSD 4 and higher. It provides line stats, previously only available via the win32-only Westell diagnostic utility.

This program was designed to ping a number of hosts at regular time intervals. It allows users to define list of hosts which will be tested and shows detailed statistics for each of them. It's written in C and requires ncurses library.

Sniffer Server - decodes TCP streams and captures packets in general The captured content may be saved to files or sent to a client over TCP/IP connection (self-defined protocol)

Easy to use network stress tester

Peep is a network monitoring tool that represents network information via an audio interface. Network diagnostics are made not only based on single network events but whether the network sounds "normal".

A simple yet powerful Power Daemon (powerd) to monitor an Uninteruptable Power Supply (UPS) with the additional capabilities of notifying remote hosts that may not have a way of knowing if their power is off.

SNMP Proxy for Windows is an SNMP Proxy extension agent for the Microsoft SNMP service.

A collection of Nagios plugins which use SNMP to query devices.

Sniffdet is an Open Source implementation of a set of tests for remote sniffers detection on TCP/IP network environments. It's composed of a flexible library (libsniffdet) and an application to run the tests.

Switzerland is a tool for testing networks, ISPs and firewalls developed by the Electronic Frontier Foundation (www.eff.org). It will spot IP packets which are forged or modified between clients, inform you, and give you copies of the modified packets.

A tool to monitor and analyse data transmitted between clients and a server through a TCP connection. This tool focuses on the data stream (software layer), not on the lower level transmission protocol as packet sniffers do.

pipeworks is a benchmarking tool for pipelines that is very similar to pipemeter. It writes its stdin to its stdout, while reporting the data flow rate to stderr. It features adjustable block size and bandwidth limiting capabilities.

ethereal patch and external plugin to enable ssl decryption for ssl v3 tls v1 sessions with RSA key exchange
