Tcpdump prints out the headers of packets on a network interface that match the boolean expression.

xinetd is a replacement for inetd, the internet services daemon. Anybody can use it to start servers that don't require privileged ports because xinetd does not require that the services in its ... [More] configuration file be listed in /etc/services. It can do access control on all services based on the address of the remote host, time of access, connection attempts, or process limits. Access control works on all services, whether multi-threaded or single-threaded and for both the TCP and UDP protocols. xinetd supports both internal access control, and the use of the libwrap library. IPv6 with access control is also supported. It can redirect service requests to other machines, and has the standard built in services, including tcpmux. [Less]

pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a ... [More] long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution. pfSense is a popular project with more than 1 million downloads since its inception, and proven in countless installations ranging from small home networks protecting a single PC to large corporations, universities and other organizations protecting thousands of network devices. This project started in 2004 as a fork of the m0n0wall project, but focused towards full PC installations rather than embedded hardware. [Less]

The Netty project is an effort to provide an asynchronous event-driven network application framework and tools for rapid development of maintainable high performance and high scalability protocol ... [More] servers and clients. In other words, Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. It greatly simplifies and streamlines network programming such as TCP and UDP socket server. [Less]

UDT is an application level data transport protocol for the emerging distributed data intensive applications over wide area high-speed networks. UDT uses UDP to transfer bulk data and it has its own ... [More] reliability control and congestion control mechanism. This new protocol is not only for private or QoS-enabled links, but also for shared networks. Furthermore, UDT is also a highly configurable framework that can accommodate various congestion control algorithms. [Less]

This project is a modern C++ library with a focus on portability and program correctness. It strives to be easy to use right and hard to use wrong. Thus, it comes with extensive documentation and ... [More] thorough debugging modes. The library provides a platform abstraction layer for common tasks such as interfacing with network services, handling threads, or creating graphical user interfaces. Additionally, the library implements many useful algorithms such as data compression routines, linked lists, binary search trees, linear algebra and matrix utilities, machine learning algorithms, XML and text parsing, and many other general utilities.

CrissCross is a small open source cross platform C++ library for console and file I/O, CPU identification (CPUID), hashing (MD2, MD4, MD5, SHA-1, SHA-256, SHA-512, Tiger), sockets (TCP and UDP only ... [More] currently), and data structures (LList, DArray, RedBlackTree, AVLTree, SplayTree, etc). CrissCross is designed to run on Windows, Linux, FreeBSD, OpenBSD, NetBSD, Mac OS X, and even the Nintendo DS. Other platforms may become supported upon request. The main idea behind CrissCross is the ability to write a program using identical calls on the major platforms, without needing to rewrite code. [Less]

hping is a command-line oriented TCP/IP packet assembler/analyzer. The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP ... [More] , ICMP and RAW-IP protocols, has a traceroute mode, the ability to send files between a covered channel, and many other features. [Less]

Cindy is a robust, scalable and efficient asynchronous I/O framework, supports TCP, SSL over TCP, UDP and Pipe.
