How to install and configure Redsocks on Centos Linux

echo "The release dist is "$RELEASE

分享一下我的经验，

 http://lilydjwg.is-programmer.com/2014/2/7/linux-really-global-http-proxy.42701.html

1. 优点： 设置一次，全局代理。连虚拟机都不要设置代理。

2. 缺点: 会停止工作，我把它放到crontab里。

1. 编译redsocks https://github.com/darkk/redsocks.

2. proxy.sh

iptables -t nat -N REDSOCKS || true

iptables -t nat -F REDSOCKS

iptables -t nat -A REDSOCKS -d 0.0.0.0/8 -j RETURN

iptables -t nat -A REDSOCKS -d 10.0.0.0/8 -j RETURN

iptables -t nat -A REDSOCKS -d 127.0.0.0/8 -j RETURN

iptables -t nat -A REDSOCKS -d 169.254.0.0/16 -j RETURN

iptables -t nat -A REDSOCKS -d 172.16.0.0/12 -j RETURN

iptables -t nat -A REDSOCKS -d 192.168.0.0/16 -j RETURN

iptables -t nat -A REDSOCKS -d 224.0.0.0/4 -j RETURN

iptables -t nat -A REDSOCKS -d 240.0.0.0/4 -j RETURN

iptables -t nat -A REDSOCKS -p tcp -j REDIRECT --to-ports 6666

iptables -t nat -A REDSOCKS -p udp -j REDIRECT --to-ports 8888

# iptables -t nat -A REDSOCKS -d 104.130.159.134/32 -p tcp -m tcp --dport 29418 -j DNAT --to-destination 127.0.0.1:6666
# iptables -t nat -A REDSOCKS -p tcp -j DNAT --to-destination 127.0.0.1:6666
# iptables -t nat -A REDSOCKS -p udp -j DNAT --to-destination 127.0.0.1:8888

iptables -t nat -A OUTPUT -p tcp -j REDSOCKS

pkill redsocks

/root/bin/redsocks -c /root/bin/redsocks.conf

3. redsocks.conf

base {

log_debug = on;

log_info = on;

daemon = on;

redirector = iptables;

}

redsocks {

local_ip = 127.0.0.1;

local_port = 6666;

ip = 10.102.248.16; <---- proxy server IP.

port = 1080;

type = socks5;

}

redudp {

local_ip = 127.0.0.1;

local_port = 8888;

ip = 10.102.248.16;

port = 1080;

}

dnstc {

local_ip = 127.0.0.1;

local_port = 5300;

}
