前言： 某些情况下，内网渗透时，代理出不来，工具传上去被杀，总之就是遇到各种问题。而最过纠结的时，我已经知道内网哪台机器有洞了..（经验多的大神飘过，如果能解决某些内网渗透时遇到的坑的问题，求分享解决方法..）
功能： 代理访问虽然是个简单的功能，但是我觉得够用了。完全可以用来直接扫描内网其他web服务器的目录，尝试内网其其他登陆入口的弱口令，或者直接代理打struts或者其他漏洞。
web扫描： 其实我觉得用web发现更加贴切，其实有了端口扫描为啥还要这个.(因为之前的代码不想动它了。)
端口扫描： 大家都懂。（此功能问题较多，我觉得如果能使用工具或者代理回来就尽量不使用此脚本进行扫描。）

用法：
1、端口扫描部分：
填好起始ip、结束ip、自定义端口、超时等，点击扫描即可，十分方便
2、内网代理部分：直接在文件后面加url参数，注意这里要带着http协议，不然可能css加载不完
