Namecoin is an open source decentralized key/value registration and transfer system based on Bitcoin technology (a decentralized cryptocurrency). It allows you to: * Securely register and transfer arbitrary names (keys), no possible censorship! * Attach values (data) to the names (currently up to 520 bytes, will be extended) * Trade and transact namecoins, the digital currency NMC To register a name, you must own some namecoins (NMC, the internal cryptocurrency used by the software).

High performance RTMP/RTSP streaming server rtmpd is a high performance streaming server able to stream (live or recorded) in the following technologies: - To and from Flash (RTMP,RTMPE, RTMPS, RTMPT, RTMPTE) - To and from embedded devices: iPhone, Android - From surveillance cameras - IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols Also, rtmpd can be used as a high performance rendez-vous server. For example, it enables you to do: - Audio/Video conferencing - Online gaming - Online collaboration - Simple/complex chat applications

"echoping" is a small program to test (approximatively) performances of a remote host by sending it TCP "echo" (or other protocol) packets. - uses the protocols echo, discard, chargen or HTTP, - uses UDP instead of TCP for the protocols which accept it (like echo), - can repeat the test and display various measures about it, - can use T/TCP on systems which support it. It's useful for checking that http servers are running and not wedged.

ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). The primary feature it provides is optional reliable, in-order delivery of packets. ENet is NOT intended to be a general purpose high level networking library that handles authentication, lobbying, server discovery, compression, encryption and other high level, often application level or dependent tasks.

hinfo is a utility that will display information about a host. It is primarily designed to find the owner of an IP block in order to direct spam complaints to where they may do some good. (maintainer's note: the DATAFILES are updated without the port version necessarily being updated. Expect drift on distinfo. See hinfo-update.) Although the home page of the software is at www.blars.org/hinfo.html, that page is not reachable from the FreeBSD.org domain.

ifdepd implements dependencies between network interfaces in a reliable way. If any of the source interfaces fails, ifdepd sets all destination interfaces to state down. If all source interfaces are active, ifdepd sets all destination interfaces to state up. For example, it can be used with carp(4) to provide failover functionality on gateways/firewalls. ifdepd is a simple replacement for ifstated and was written because of problems with ifstated.

The HTTP Time Protocol (HTP) is used to synchronize a computer's time with web servers as reference time source. Htpdate will synchronize your computer's time by extracting timestamps from HTTP headers found in web servers responses. Htpdate can be used as a daemon, to keep your computer synchronized. Accuracy of htpdate is usually better than 0.5 seconds (even better with multiple servers). Htpdate can also work through http proxy.

"httpry is a specialized packet sniffer designed for displaying and logging HTTP traffic. It is not intended to perform analysis itself, but to capture, parse, and log the traffic for later analysis. It can be run in real-time displaying the traffic as it is parsed, or as a daemon process that logs to an output file. It is written to be as lightweight and flexible as possible, so that it can be easily adaptable to different applications."

IP2Location is a C library that enables the user to find the country, region, city, latitude, longitude, zip code, time zone, ISP, domain name, connection type, area code, weather, mobile network, elevation, usage type by IP address or hostname originates from. It contains a demo IP2Location IP-COUNTRY BIN database which consists of real data for IP address range 0.0.0.0 to 99.255. 255.255. This database contains IP address blocks as key and countries as values.

The ipsumdump program summarizes TCP/IP dump files into a self-describing ASCII format easily readable by humans and programs. Ipsumdump can read packets from network interfaces, from tcpdump files, and from existing ipsumdump files. It will transparently uncompress tcpdump or ipsumdump files when necessary. It can randomly sample traffic, filter traffic based on its contents, anonymize IP addresses, and sort packets from multiple dumps by timestamp. Also, it can optionally create a tcpdump file containing actual packet data.
