目前，已经有不少的Sniff工具软件，如Windows环境下，最富盛名的工具是Netxray和Sniffer pro，用它们在 Windows环境下抓包来分析，非常方便。在UNIX环境下如Sniffit，Snoop，Tcpdump，Dsniff 等都是比较常见的。这里介绍一个用C语言和网络数据包和分析开发工具libpcap及winpcap实现的简易网络Sniffer。-Currently, there have been numerous Sniff software tools, such as the Windows environment, the most famous tool is the Sniffer pro Netxray and use them in the Windows environment capturing Packet analysis, very convenient. In the UNIX environment as Sniffit, Snoop, Tcpdump, such as Dsniff are relatively common. Presented here with a C language and network packet analysis and the development of tools to achieve libpcap and winpcap Simple Network Sniffer.

做多客户端与服务器端的双向通信，采用QLocalSocket/QLocalServer实现起来简单，但通信效率太低，客户端发数据，服务器端的readyRead信号延时约100ms（看QT源码，发现里面用的是100ms定时器来检测信号），后来自己照着QLocalSocket的思路封装了windows的命名管道，采用多线程来接收数据，在本机上测试通过，通信效率有明显改善。-To do more client and server-side two-way communication, using QLocalSocket/QLocalServer to achieve them simple, but the communication efficiency is too low, the client made the data, the server-side readyRead the signal delay of about 100ms (see QT source code found inside using a 100ms timer device to detect the signal), and later their shining QLocalSocket encapsulates the idea of windows named pipes, using multiple threads to receive data, tested on this machine, the communication efficiency has clearly improved.
