SecDev.org/projects/scapy >>Scapy is a powerful interactive packet manipulation program. It is able to forge or decode packets of a wide number of protocols, send them on the wire, capture them, match requests and replies, and much more. It can easily handle most classical tasks like scanning, tracerouting, probing, unit tests, attacks or network discovery (it can replace hping, 85% of nmap, arpspoof, arp-sk, arping, tcpdump, tethereal, p0f, etc.). It also performs very well at a lot of other specific tasks that most other tools can't handle, like sending invalid frames, injecting your own 802.11 frames, combining technics (VLAN hopping+ARP cache poisoning, VOIP decoding on WEP encrypted channel, ...), etc. See the quick demo: an interactive session.
MasterShaper.org >>MasterShaper is a network traffic shaper which provides a Web Interface for Quality of Servcie (QoS) functions of newer Linux 2.4- & 2.6-Kernel-Series.
BandwidthD.sf.net >>BandwidthD tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization. Charts are built by individual IPs, and by default display utilization over 2 day, 8 day, 40 day, and 400 day periods. Furthermore, each ip address's utilization can be logged out at intervals of 3.3 minutes, 10 minutes, 1 hour or 12 hours in cdf format, or to a backend database server. HTTP, TCP, UDP, ICMP, VPN, and P2P traffic are color coded.

Project-Observer.org >>Project Observer is an autodiscovering PHP/MySQL/SNMP/CDP based network management system focused primarily on Cisco and Linux/BSD networks. It is capable of of automatically generating network infrastructure diagrams using link data harvested via CDP from Cisco network hardware.
Emulab.net >>Network Emulation Testbed Home Emulab is a network testbed, giving researchers a wide range of environments in which to develop, debug, and evaluate their systems. The name Emulab refers both to a facility and to a software system.
appinf.com/poco >>POCO, the C++ Portable Components, is a collection of open source C++ class libraries that simplify and accelerate the development of network-centric, portable applications in C++. The libraries integrate perfectly with the C++ Standard Library and fill many of the functional gaps left open by it. Their modular and efficient design and implementation makes the C++ Portable Components extremely well suited for embedded development, an area where the C++ programming language is becoming increasingly popular, due to its suitability for both low-level (device I/O, interrupt handlers, etc.) and high-level object-oriented development. Of course, POCO is also ready for enterprise-level challenges.
akkada.tivi.net.pl >>akk@da is a simple network monitoring system designed for small and middle size computer networks. Its purpose is to quick detect system or network fault and to display information about detected problem for administrator. akk@da is designed as a pro-active network monitor. It does not wait for information from any agents, systems, etc. It collects information itself every single minute (you can decrease this period even to 1 second if you need). Almost all services of the monitored hosts are discovered automatically.
VirtualGL.org >>VirtualGL is an open source package which provides hardware-accelerated 3D rendering capabilities to thin clients. Normally, when you run a 3D application inside a thin client environment (e.g. VNC, remote X11, NX, etc.), the 3D application either does not work at all, is forced to use a slow software 3D renderer, or (worse) is forced to send every 3D command and piece of 3D data over the network to be rendered on the client machine. With VirtualGL, the 3D rendering commands from the application are intercepted at run time and redirected onto the server's 3D accelerator hardware. The resulting rendered images are then read back from the 3D hardware and composited into the appropriate window on the user's desktop. This produces a completely seamless shared 3D environment that performs fast enough to take the place of a dedicated 3D workstation.
