信使小精灵,是一个简易的聊天工具。主要是演示了网络编程的主要步骤。本程序使用封装好的函数库，使得应用层不需要考虑网络消息是如何被接受和发送的，也不需要考虑数据粘包和丢包的刺手问题，你只要调用相应的函数就可以了。函数库为你做好了这些工作。你只需要定义自己的协议头和消息结构体，定义好网络消息的回调函数就可以了。-messenger elf is a simple chat tools. A major demonstration is the main network programming steps. The programs use Packaging good libraries, makes application layer need not consider the network news is how it has been accepted and sent, and do not need sticky packets of data and packet loss of a thorn in hand, as long as you call the corresponding function on it. Functions well as your work. You only need to define its own agreement head and the structure of news, the definition of a good network news callback function on it.

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.
