【摘要】 目的解决Linux系统中网络信息的捕获与分析。方法主要通过创建socket套接口实现网络数据的捕获,通过数据包捕获与协议分析的被动流量监测获得各个协议层次的流量指标。结果在网路上截取/阅读位于OSI协议模型中各个协议层次上的数据包。结论此方法在Linux系统中可简便快捷地实现,可以捕获和分析大量网络性能信息、网络服务状况以及网络所存在的弱点。更多还原

【Abstract】 Aim To intercept and seize the stream of network.Methods Through the passive stream snooping which can intercept the data and analyze the protocols to obtain the stream on every layer of the protocol.Results The program can intercept or read the data on every layer of protocols inside the OSI protocol mode.Conclusion This method can be easily implemented based on Linux.Much information can be gained through the intercept and analysis of the stream of network,including that of network security,performance of network′s service,as well as the possibility of potential attack and vulnerability.更多还原
