ENet for C# wraps the C-language ENet networking library. For games and other realtime applications, if you use TCP, old data can hold up newer data, even if it is no longer relevant (old positions, etc.). Your players will perceive any lost packet as a "lag burst". ENet supports multiple in-order streams of data, and allows you to decide on reliability on a per-packet basis. The library is useful for both client-server and peer-to-peer architectures.
libnetfilter_cttimeout is an interface to Netfilter Connection Tracking timeouts. It provides a userspace library which provides a programming interface to the fine-grained connection tracking timeout infrastructure. With this library, you can create, update, and delete timeout policies which can be attached to traffic flows.
Collax Business Server is an all-in-one Linux server for small- and medium-sized businesses. It delivers all the important network services within a heterogeneous business environment for communication, infrastructure, compliance, groupware, and storage, all in a reliable and secure way which is easy to manage. It also provides essential security functions such as firewalling and virus and spam filtering, to protect against hacker attacks, viruses, and unsolicited email messages.
MinimalModbus is an easy-to-use Python module for talking to instruments (slaves) from a computer (master) using the Modbus protocol. Example code includes drivers for Eurotherm and Omega process controllers. The only dependency is the pySerial module. This software supports the ‘Modbus RTU’ serial communication version of the protocol, and is intended for use on Linux, OS X, and Windows platforms. It has been tested with Python2.6, Python2.7, and Python3.2.
Herqq UPnP (HUPnP) is a software library for building UPnP devices and control points conforming to the UPnP Device Architecture version 1.1. It is designed to be simple to use and robust in operation. It is built using the Qt framework, following many of the design principles and programming practices used in the Qt framework. It integrates into Qt-based software smoothly and enables truly rapid UPnP development.
netsniff-ng is a high performance Linux network sniffer for packet inspection. It is similar to analyzers like tcpdump, but without the need to perform system calls for fetching network packets. A memory-mapped area within kernelspace will be used for accessing packets, so there is no requirement for copying them to userspace (a 'zero-copy' mechanism). For this purpose, netsniff-ng is libpcap independent, but nevertheless supports the pcap file format for capturing, replaying, and performing offline analysis of pcap dumps. The project is focused on building a robust, clean, and secure analyzer and utilities that complete netsniff-ng as a support for penetration testing. netsniff-ng can be used for protocol analysis, reverse engineering, and network debugging.
