网路嗅探器能够分析出一段网络中数据包使用的协议、IP、源端口等内容，经常用来检测一段网络的运行状况，排除网络故障。网路协议纷繁众多，采用Lua嵌入脚本来解析协议数据包，能够使程序灵活的扩展。本文简要介绍了嗅探器和Lua的概念；然后着重阐述了Lua脚本嵌入方案关键技术，对如何实现系统功能给予详细的描述；最后展示了Lua嵌入脚本实现的功能。通过测试表明，Lua嵌入脚本模块能够有效的使用新编的嵌入协议脚本来解析相应数据包。

Because network sniffer can analysis the protocol type used, IP address, source port of network packet, it is often used to detect the network’s working status, and rule out network failure. Network protocols being numerous,we adopt embedded Lua scripts to analysis protocol packet, in order to provide lfexible expansion capabilities for the program. This paper gives the brief concepts of network sniffer and Lua, and then focuses on key technologies in design of the Lua script embedded and detailed description on how to implement the functions;Finally, screenshots and text descriptions showed the functions of the embedded Lua scripts. Through the texts, it is easy to see that Lua script embedded module can effectively analysis the network packet using the special protocol described by the Lua scripts.
