Description: 穿透HTTP代理的linux下的C源程序，值得借鉴-This is a transparent proxy server. It can be started from inetd to
service HTTP requests, or run as a stand-alone daemon. HTTP requests
are transparently accepted and passed to the WWW proxy cache for
handling. The HTTP request line is modified into a form usable by
the WWW proxy cache. The destination WWW site name is extracted from
the HTTP headers to avoid DNS lookups.

Description: dnspod-sr 是一个运行在 Linux 平台上的高性能的递归 DNS 服务器软件，具备高性能、高负载、易扩展的优势，非 BIND 等软件可以比拟。dnspod-sr 依托于 DNSPod 多年运营和优化 DNS 服务的经验，针对国内复杂的网络情况，对递归 DNS 进行了一系列的优化，比较其他开源软件，性能得到大幅提升。
特性
高性能，比所有流行的开源 DNS 软件性能高出2倍以上
安全，能抵御一般攻击
稳定，有效降低解析失败率
主动刷新缓存，响应速度更快
易于扩展，非常容易部署
防污染，能够正确解析被污染域名-dnspod-sr is a run on the Linux platform, high-performance recursive DNS server software with high-performance, high-load, easy to extend the advantages of non-BIND software can match. dnspod-sr relying on years of experience in operations and optimization DNSPod DNS service for the domestic complex network situation, a series of recursive DNS optimization, compared with other open source software, performance is greatly improved. Characteristics of high-performance, more than two times higher than the safety of all popular open source DNS software performance, stable and can withstand general attacks, effectively reducing the failure rate of the initiative to resolve the cache is flushed, easy to expand faster response and very easy to deploy anti-pollution, can correctly parse contaminated domain

Description: 驱动级域名劫持
就是访问A.com转到b.com，当然如果改成访问A就丢包，那就变成拦截指定网站了。首先用抓包工具发现，访问某网站时，（如果本地没有该网站的DNS缓存）首先会发DNS查询包（UDP），然后会与该网站建立连接，然后，发http请求包。
观察包内容，需要把发出的包的目标改成我们的目标，然后把响应的包中我们改过的东西改回来，就是欺上瞒下。代码不多，重点是演示了如何获取TCP与UDP的接收到包的内容。仅适用于XP：
bin会将www.baidu.com劫持到ip138.com-Drive level domain hijacking is to visit A.com to b.com, of course, if A is dropping into access, it becomes blocked designated site. First discovered by capturing tool, visit a website, (if there is no local DNS cache of the site) will first send a DNS query packets (UDP), then establish a connection with the site, and then send http request packet. Observe the contents of the package, we need to change the target packet sent our goal, then put the package in response to the things we turn to come back, that is, superiors and subordinates. Code much focus is to demonstrate how to get the contents of TCP and UDP packets received. Only applies to XP: bin will www.baidu.com hijacked to ip138.com
