摘　　要：深入分析了Netfilter的基本原理和内核模块编程,在此基础上设计了一个基于Netfilter机制的可对网络数据包进行抓捕分析的网络监听器。程序运行在linux内核态,具有很高的效率,数据包处理能力较强。同时Netfilter框架的使用使其具有良好的代码结构,易于维护和扩展。Based on the analysis of the the basic principles of Net-filter and kernel module programming, this paper has designed a net sniffer module that can catch the net data package. This module runs on the kernel state of Linux, with high efficiency and high capability of data packet processing. It has good code structure and is easy to be maintained and expanded because of the Net-filter framework.
