Open Source C Networking Software for Mac

PeerGuardian is a privacy oriented firewall application. It blocks connections to and from hosts specified in huge blocklists (thousands or millions of IP ranges). Its origin seeds in targeting aggressive IPs while you use P2P. PeerGuardian Linux: Not developed actively anymore. Team might still be around. Some unreleased changes on git. Outdated technology. Peerguardian OS X: Not developed anymore. We've lost contact with the OS X developer. PeerGuardian Windows: Not developed anymore. It's highly recommended to use PeerBlock instead, which is a continuation of PeerGuardian's development in Windows, with bug fixes and support for Windows Vista and Windows 7. Collaboration with peerblock.com is welcome! PeerGuardian is an open project. Not only is its source code open for you to read, use, and modify - but the project is open for you to join and contribute in any form (code, documentation, bug reports, web and support).

Siproxd is a proxy/masquerading daemon for the SIP protocol. It allows SIP clients (softphones & hardphones) to work behind an IP masquerading firewall or router.

Mnet is a distributed file store. It is formed by an emergent network of autonomous nodes which self-organize to make the network robust and efficient.

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

A Free SOCKS proxy server for Linux, macos and FreeBSD

Fleming File Sharing System is a networked file sharing system. It should be much more reliable and user-friendly than FTP or netbios's stuff.

XSockets - open, lightweight and highly portable library of universal and eXtensible Super Sockets for point-to-point communication. A unified API for many communication methods between programs and/or devices (e.g. TCP/IP sockets,serial link,pipes,IrDA)

An alternative Identification system that is a replacement for Microsoft's Passport and the Liberty Alliance. Its a simple architecture that is setup so anyone can run a server and thereby have control over their online identification.

OpenDMTP is a protocol/framework that allows communications with small devices (mobile phones, PDA's, and other high-latency/low-bandwidth devices), especially geared towards the transmission of GPS, temperature, and other remote monitoring information.

SipSpy is a distributed monitoring tool for SIP networks. SpyAgents run on each of the nodes to be monitored, and a SipSpy connects to each of these nodes, receiving information and displaying it in real-time for all the SIP packets monitored.

XLattice is a communications infrastructure for server-assisted peer-to-peer networks. Initial implementation is Java (and so platform-independent) with C/C++ for Linux and then Windows to follow.

Xealous Nets is a set of programs to be used as network calculators. One of them performs classful calculations and the other one performs classless calculations, that is, CIDR.

apt-got builds and supervises a partial (or full) Debian mirror, that is filled on-the-fly by apt-get requests. But there's more! Its modular mirror engine is ready for customized mirroring algos. So you can easily make your own module! (Eg for apt4rpm)

A Ruby interface to the Spread Group Communication System.
