ss-redir+dnsmasq+iptables 透明代理

计算机网络技术 huahua 1700℃

所需环境
树莓派一个
路由器
境外vps shadowsocks-libev 环境
原理
数据发起—-路由器—dns(树莓派)–iptables局域网放行–dnsmasq查询真实并缓存–局域网iptables放行—-路由器—网关(树莓派)—iptables过滤国内直接放行,国外数据打包socks5走本地1080端口外出。
A。安装shadowsocks

git clone https://github.com/shadowsocks/shadowsocks-libev.git
cd shadowsocks-libev

安装编译环境

sudo apt-get install build-essential autoconf libtool libssl-dev gawk debhelper dh-systemd init-system-helpers pkg-config

树莓派这里会出问题,没法安装dh-systemd这里直接编译安装

./configure–prefix=/usr/local/shadowsocks
make && make install
ln -s /usr/local/shadowsocks/bin/ss-redir ss-redir

生成deb包

dpkg-buildpackage -us -uc -i

安装刚生成的deb包,在github主页上有介绍。这里是debian安装的过程编译好的deb,及其他配置文件

sudo dpkg -i shadowsocks-libev*.deb

使用ss-redir -c /etc/redir.json   这里local_adress必须写0.0.0.0,127.0.0.1会出问题

{  
“server”:”服务器地址”,  
“server_port”:服务器开放的端口,  
“local_address”:”0.0.0.0″,  
“local_port”:本地端口,  
“password”:”密码”,  
“timeout”:600,  
“method”:”aes-256-cfb”,  
“fast_open”:false  
}

B。iptables及转发

#vim /etc/sysctl.conf

net.ipv4.ip_forward=1

linux做网关要开启数据转发#sysctl -p

编写2个脚本一个启动用一个停止用

启动的iptables.sh 还有flash.sh 清理用的iptables

简单的

#!/bin/bash  
# Create new chain  
iptables -t nat -N SHADOWSOCKS  
iptables -t nat -A PREROUTING -p tcp -j SHADOWSOCKS  
# Ignore your shadowsocks server’s addresses  
# It’s very IMPORTANT, just be careful.  
iptables -t nat -A SHADOWSOCKS -d 服务器ip地址 -j RETURN  
# 这一步非常重要!到服务端的出口数据不要再进行重定向,否则进入死循环  
#去除内网地址  
iptables -t nat -A SHADOWSOCKS -d 0.0.0.0 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 127.0.0.1 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 192.168.0.0/16 -j RETURN

iptables -t nat -A SHADOWSOCKS -d 8.8.0.0/16 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 0.0.0.0/8 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 10.0.0.0/8 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 127.0.0.0/8 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 169.254.0.0/16 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 172.16.0.0/12 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 192.168.0.0/16 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 224.0.0.0/4 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 240.0.0.0/4 -j RETURN  
iptables -t nat -A SHADOWSOCKS -d 0.0.0.0/254.0.0.0 -j RETURN

#还可以加如国内ip段参见 https://gist.github.com/wen-long/8644507  
# Anything else should be redirected to shadowsocks’s local port  
iptables -t nat -A SHADOWSOCKS -p tcp -j REDIRECT –to-ports 1080

# Apply the rules  
#iptables -t nat -A OUTPUT -p tcp -j SHADOWSOCKS  
# 对于本机全局代理必须是加入到OUTPUT链中,上面这句可以不加,至此脚本结束

清理脚本 flash.sh   因为debian下,iptables不是服务。没有启动停止的概念是实时生效的,清理完规则相当于其实停止了。iptables-save > qqq       恢复 iptables-restore < qqq

#!/bin/bash  
iptables -F  
iptables -X  
iptables -t nat -F  
iptables -t nat -X  
iptables -t mangle -F  
iptables -t mangle -X  
iptables -P INPUT ACCEPT  
iptables -P OUTPUT ACCEPT  
iptables -P FORWARD ACCEPT

C.dnsmasq

apt-get install network-manger dnsmasq

启用本地dns

如果使用了networkmanger要这样设置启用dnsmasq

Set this in /etc/NetworkManager/NetworkManager.conf:

[main]

dns=dnsmasq

如果没有那么

修改默认的dns配置文件

/etc/reslov.conf

nameserver 127.0.0.1

修改/etc/reslov.dnsmasq(需自己创建)

nameserver 8.8.8.8  
nameserver 8.8.4.4

编辑/etc/dnsmasq.conf

在最后加入

conf-dir=/etc/dnsmasq.d/,*.conf  
listen-address=127.0.0.1,192.168.1.104  
bind-interfaces  
cache-size=100000  
domain-needed  
resolv-file=/etc/resolv.dnsmasq

其中cache缓存10000条

resolv-file=/etc/resolv.dnsmasq 上游dns地址

listen-address=127.0.0.1,192.168.1.104   为局域网及本机提供dns服务

conf-dir=/etc/dnsmasq.d/,*.conf        接受目录下的所有配置文件

/etc/dnsmasq.d/t.conf内容,意思是这些地址走208.67.222.222的5353端口查询

update.rc 来开机启动dnsmasq

—————————————————————————————————————————–

扩展知识

启动守护进程

设置为开机启动:

systemctl enable dnsmasq  

立即启动 dnsmashq:

systemctl start dnsmasq

查看dnsmasq是否启动正常,查看系统日志:

journalctl -u dnsmasq

—————————————————————————————————————————–

D。使用

systemctl enable dnsmasq

systemctl start dnsmasq

ss-redir -c /etc/redir.json

./iptables.sh

前提,设置静态ip

auto eth0  
allow-hotplug eth0  
iface eth0 inet static  
address 192.168.1.104  
netmask 255.255.255.0  
gateway 192.168.1.1

路由器修改dncp里面的dns为192.168.1.104.网关也是192.168.1.104
