【摘要】 针对网络管理中的安全问题,以Winpcap为开发平台,使用VisualC++为开发工具,设计了一个网络嗅探器。分析了网络嗅探器的基本工作原理,描述了Winpcap捕获数据包的程序流程,最后给出具体实现的关键函数。结果表明,这种网络嗅探器结构简单,捕获数据快,对网络的安全管理具有重要意义。更多还原

【Abstract】 Aiming at the security problems of network management,the paper proposes a network sniffer with Winpcap as development platform and Visual C++ as development tool Winpcap and visual C++.The fundamental principle of the network sniffer is analyzed and the procedure during which Winpcap captures the packet is introduced.The key function is finally given.The results show that the network sniffer has such advantages as simple structure and fast data capture,which is signifant to the network security and management.更多还原
