1.前言
时常会遇到需要部分APP有严格风控如（地域IP限制、IP访问频次限制等）。本次利用redsocks + iptables 来实现安卓全局代理切换。顺便记录下，无脑使用。支持http和socks
2.redsocks 介绍
redsocks 可将任何 TCP 连接重定向到 Socks4、Socks5 或 HTTPS (HTTP/CONNECT) 代理服务器。
Socks5/HTTPS 连接支持登录/密码身份验证。Socks4仅支持用户名，密码被忽略。对于 HTTPS，目前仅支持 Basic 和 Digest 方案。
3.iptables 介绍
iptables 本质上是定义linux防火墙规则的工具，定义的规则，可以让在内核空间当中的netfilter来读取，并且实现让防火墙工作。
3.1五处控制规则
1.PREROUTING (路由前)
2.INPUT (数据包流入口)
3.FORWARD (转发管卡)
4.OUTPUT(数据包出口)
5.POSTROUTING（路由后）
3.2数据流走向
4.环境准备
1 2 3 4 5 | # 测试使用版本 redsocks 0.4、iptables v1.4.20# https://github.com/darkk/redsocks 直接拉取代码进行编译apt-get install libevent-devcd redsocksmake |
5.设置代理
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 | # 启动代理并配置项，<IP> 代理IP <PORT>端口# proxy.sh 一共7个入参，详情查看脚本/proxy.sh start http <IP> <PORT> false "" ""# 对代理ip不再代理操作，<IP> 代理IP/iptables -t nat -A OUTPUT -p tcp -d <IP> -j RETURN# 添加群控软件不走全局代理规则，<UID>应用程序，如果你想让安卓上某个进程的网络都不走带可以可以这样设置/iptables -t nat -m owner --uid-owner <UID> -A OUTPUT -p tcp -j RETURN# 对应域名不走代理<xxx1> 不需要走代理的域名/iptables -t nat -A OUTPUT -p tcp -d <xxx1> -j RETURN/iptables -t nat -A OUTPUT -p tcp -d <xxx2> -j RETURN# 添加http代理规则，可以按照自己的业务场景进行端口代理设置/iptables -t nat -A OUTPUT -p tcp --dport 80 -j REDIRECT --to 8123/iptables -t nat -A OUTPUT -p tcp --dport 443 -j REDIRECT --to 8124/iptables -t nat -A OUTPUT -p tcp --dport 5228 -j REDIRECT --to 8124# 添加socks5代理规则/iptables -t nat -A OUTPUT -p tcp -j REDIRECT --to 8123 |
6.关闭代理
1 2 3 4 | # 清除所有代理配置/iptables -t nat -F OUTPUT# 清除配置并干掉进程，具体查看proxy.sh 脚本/proxy.sh stop |
7.proxy.sh 代理脚本
