DNS欺骗在嵌入式Web服务器的应用

摘要

为解决嵌入式Web服务器操作繁杂的问题,讨论DNS欺骗技术的基本原理与嵌入式Web服务器的常用技术,提出将DNS欺骗技术与嵌入式Web服务器相结合实现网页的重定向的解决方案.结合嵌入式设备内存和硬件的限制,分析Web服务器与DNS服务器的网络数据后,采用定时器中断与事件中断的设计,在嵌入式设备稳定工作的前提下,实现DNS欺骗技术与嵌入式Web服务器的结合.采集对比了网络数据,实验结果验证了该设计的可行性.%To solve the problem of complex operation of embedded Web server,after discussing the principles of the DNS spoofing and common techniques,a solution combining DNS spoofing and embedded Web server was proposed.Because of the restriction of the resource of embedded device,after analyzing data of Web server as well as DNS server,a design including timer interrupt and event interrupt was put forward.On the basis of the steady operation of embedded device,the combination of DNS spoofing and embedded Web server was realized.After gathering and contrasting network data,the feasibility of the design was verified.
