Condor is a high throughput system, scheduling and providing large amounts of computational power over a long period of time. It provides the efficient use of a large variety of systems, from idle desktop workstations and dedicated clusters to grid systems all over the world, while its incredibly flexible configuration implements and maintains the machine owner's desired policy for the machine's availability.
ngrep strives to provide most of GNU grep's common features, applying them to the network layer. ngrep is a pcap-aware tool that will allow you to specify extended regular or hexadecimal expressions to match against data payloads of packets. It currently recognizes IPv4/6, TCP, UDP, ICMPv4/6, IGMP and Raw across Ethernet, PPP, SLIP, FDDI, Token Ring, and null interfaces, and understands BPF filter logic in the same fashion as more common packet sniffing tools, such as tcpdump and snoop.
RabbIt is a mutating, caching Web proxy used to speed up surfing over slow links like modems. It does this by removing advertising and background images and scaling down images to low quality JPEGs. RabbIT is written in Java and should be able to run on any platform. It does depend upon an image converter if image scaling is on. The recommended image converter is "convert" from the ImageMagick package.
traffic-vis is a suite of tools to help determine which hosts have been communicating on an IP network, with whom they have been communicating and the volume of communication taking place on a host by host basis. Reports can be generated in ASCII and/or HTML format. traffic-vis can also generate Postscript(tm) and GIF charts showing which hosts have communicated with each other.
uIP is probably the smallest implementation of the TCP/IP protocol stack ever written in a high level language; the code footprint is on the order of a few kilobytes and RAM usage is on the order of a few hundred bytes. uIP is intended to be used in embedded systems running low end 8- and 16-bit microcontrollers.
Netdude (the NETwork DUmp data Displayer and Editor) is a framework for inspection and manipulation of tcpdump tracefiles. It is separated into a GUI-based frontend and a backend library that performs the actual packet manipulation. Both the front- and backend can be extended using plugins, in order to add support for new protocols and to provide modular code to other developers.
