摘要： 给出了一种在数据链路层上开发网络嗅探器的方法。该方法实现的嗅探器能够直接通过网卡驱动程序捕获网络上的数据帧,适用于各种类型数据包的捕获,比在协议栈的网络层捕获数据包具有更强大的功能。

关键词: 网络嗅探器, 数据链路层, 套接字, 以太帧

Abstract: A method to develop network sniffer based on data link layer was put forward. The sniffer implemented by this method can capture data frame on network by driver of network card. It can be used to capture all kinds of data packets. Compared with those sniffers which capture data packet based on network layer, it is more powerful.

Key words: network sniffer, data link layer, socket, ethernet frame
