<1> 郑重声明
－软件仅供科研、学习、教育等一切合法目的使用，严禁一切违法行为
－由于采用的是VPN技术，所有的网络通信都有可能被截获，涉及个人财产安全的操作请绕行

<2> 欢迎使用 UVPN 科学上网神器
一直以来，我们都可以修改电脑上的hosts文件实现科学上网，而在Android系统中，hosts文件保存在system分区中，在没有root的情况下，是无法修改的。本软件的存在，使得你可以“修改”hosts文件，实现科学上网。

<3> 特点如下
－可以导入、导出hosts文件
－可以对本软件中的hosts文件进行导入、导出的操作
－内建DNS服务器，并且可以配置上游DNS服务器
－使用shadowsocks ss-server/ss-local软件，可以配置连接shadowsocks远程服务器
－包含流量流计，数据来自ss-server服务，但要注意统计只包含TCP连接相关的数据
－由于使用本软件会创建VPN连接，而Android系统同一时刻只能有VPN连接，VPN连接数量受限
－包含DNS服务器、ss-server服务、ss-local服务、VPN服务、udpgw服务，各模块可以独立运行

<4> 注意事项
－DNS服务器会占用本机的5353端口，用于接收DNS请求报文
－shadowsocks – ss-server会占用本机的8443端口，用来与ss-local进行socket通信
－shadowsocks – ss-local（socks5 server)会占用本机的1080端口，用来与badvpn - tun2socks进行socket通信
－badvpn – udpgw会占用本机的8700端口，用来与badvpn - tun2socks进行socket通信
－Android系统支持Always-on VPN, 本软件暂时不支持这个功能，请不要打开这个选项
