摘　　要：网络数据包截获技术是指利用计算机技术截获网络上的数据包,然后根据数据包头部的源主机地址、目标主机地址、服务协议端口等字段特性过滤掉不关心的数据,再将用户感兴趣的数据发送给更高层的应用程序进行分析。文章探讨了基于Linux系统下数据包截获技术。The technology of network packet capturing which is by use of computer technology intercepted the packet that transmit in network, and according to the department of source host address, the target host address, port services agreement and other fields filter characteristics of packet header, filter users do not care about, and then the packet that users are interested packet sent to a higher level of applications for analysis. The paper discusses the packet interception technology based on Linux system.
