摘要
针对安全问题在网络管理中的日益突出,基于Winpcap开发平台,使用Visual C++作为开发工具,设计并开发了一个网络嗅探器。该文设计了一个GUI程序,实现IP、TCP、UDP数据包捕获和分析。同时分析了网络嗅探器的基本工作原理,并阐述了应用捕获数据包流,根据Winpcap关键功能给出了其具体实现。结果表明,该网络嗅探器结构简单,捕获数据快速,对网络安全管理具有重要意义。
Security problem in network management becomes increasinglyserious,a network sniffer was designed and devel oped based on Winpcap development platform,with Visual C + + as a development tool to solve the problem.This paper introduc es the design of a GUI program which uses IP,TCP,UDP to capture and analyze data packets At the sametime,we analyze the ba sic working principle of network sniffer,and expound the application of capture data packet flow,according to theWin pcap key function give the concrete realization.The results show that,the network structure is simple and the speed of cap ture of data is quick.Hence it is of the vital significance to the network security management.
