Projects

tcpdump

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

Snort

Snort® is an open source network intrusion prevention and detection system using a flexible rule-driven language, which combines the benefits of signature, protocol and anomaly based inspection methods. With millions of downloads to date, Snort is the most widely deployed intrusion detection and ... [More] prevention technology worldwide and has become the de facto standard for the industry. [Less]

xinetd

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 configuration file be listed in /etc/services. It can do access control on all services based on the ... [More] 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]

Netty Project

Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. Netty is a NIO client server framework which enables quick and easy development of network applications such as protocol servers and clients. ... [More] It greatly simplifies and streamlines network programming such as TCP and UDP socket server. [Less]

IPCop Firewall

IPCop Linux is a complete Linux distribution whose sole purpose is to protect the networks on which it is installed.

m0n0wall

m0n0wall (monowall) is a project aimed at creating a complete, embedded firewall software package that, when used together with an embedded PC, provides all the important features of commercial firewall boxes (including ease of use) at a fraction of the price (free software). m0n0wall is based on a ... [More] bare-bones version of FreeBSD, along with a web server, PHP and a few other utilities. The entire system configuration is stored in one single XML text file to keep things transparent. m0n0wall is probably the first UNIX system that has its boot-time configuration done with PHP, rather than the usual shell scripts, and that has the entire system configuration stored in XML format.

Suricata IDS/IPS

Suricata is an open source Intrusion Detection and Prevention (IDS/IPS) engine. Suricata is developed by the Open Information Security Foundation and its supporting vendors. The engine is multi-threaded, has native IPv6 support, file extraction capabilities and many more features. It's capable ... [More] of loading existing Snort rules and signatures and supports many frontends through Barnyard2. [Less]

libevent - an event notification library

The libevent API provides a mechanism to execute a callback function when a specific event occurs on a file descriptor or after a timeout has been reached. It is meant to replace the asynchronous event loop found in event-driven network servers.

JGroups

JGroups is a toolkit for reliable multicast communication. (Note that this doesn't necessarily mean IP Multicast, JGroups can also use transports such as TCP). It can be used to create groups of processes whose members can send messages to each other. The main features include * Group ... [More] creation and deletion. Group members can be spread across LANs or WANs * Joining and leaving of groups * Membership detection and notification about joined/left/crashed members * Detection and removal of crashed members * Sending and receiving of member-to-group messages (point-to-multipoint) * Sending and receiving of member-to-member messages (point-to-point) [Less]

dlib C++ Library

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 thorough debugging modes. The library provides a platform abstraction layer for common tasks such as ... [More] 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.
