0x01 Make it work

1. wget https://bootstrap.pypa.io/get-pip.py && python get-pip.py
2. pip install shadowsocks
3. sslocal -s your-ss-ip -p 443 -k "your-ss-code" -l 1080 -m aes-256-cfb --user nobody -d start
4. curl --socks5 127.0.0.1:1080 ip.cn
5. yum -y install privoxy
6. service privoxy start
7. cp /etc/privoxy/config /etc/privoxy/config_bak
8. vim /etc/privoxy/configensure below lines are not commented, line1 usually not, line2 need modify

    listen-address 127.0.0.1:8118 
    forward-socks5t / 127.0.0.1:1080 . 
   

9. run below in bash

    export http_proxy=http://127.0.0.1:8118
    export https_proxy=http://127.0.0.1:8118
   

10. chkconfig privoxy on && service privoxy start
11. curl ipinfo.io

0x02 Be elegant

1. CentOS install

    yum -y install privoxy pip -y
    pip install shadowsocks
    cp /etc/privoxy/config /etc/privoxy/config_bak
   

   Ubuntu install

    sudo apt install python-pip git privoxy -y
    pip install -U git+https://github.com/shadowsocks/shadowsocks.git@master
    cp /etc/privoxy/config /etc/privoxy/config_bak
   

2. vim /etc/privoxy/config uncomment below line

    forward-socks5t / 127.0.0.1:9050 . 
   

3. save below code to a file like setproxy , then . setproxy on means open,. setproxy off means shutdown

    #!/bin/bash
   
    ip=1.1.1.1
    port=11111
    key=123456
   
    if [ "$1" == "on" ]; then
        sslocal -s $ip -p $port -k $key -l 9050 -m aes-256-cfb --user nobody -d start
        service privoxy start
        export http_proxy=http://127.0.0.1:8118
        export https_proxy=http://127.0.0.1:8118
    elif [ "$1" == "off" ]; then
        sslocal -s $ip -d stop
        service privoxy stop
        export http_proxy=""
        export https_proxy=""
    elif [ "$1" == "status" ]; then
        service privoxy status
    elif [ "$1" == "log" ]; then
        tail -f /var/log/shadowsocks.log
    elif [ "$1" == "test" ]; then
        sslocal -s $ip -p $port -k $key -l 9050 -m aes-256-cfb
   
    else
        echo 'Please input argument: on,off,status'
    fi
    echo 'Now your ip is: '
    curl ipinfo.io
    echo ''
   

0x03 Another host comes

An image that the stream flow:

• Listen: ss-server[socks 1080] –> privoxy(forward-socks5t[socks 1080]>listen-address[http,https 8118])
• Request: application, like curl –> localhost[http,https 8118]

Now comes another machine: C (A is ss-server, B is ss-client configured as 0x02), let C join the play:

1. on B, change listen-address 127.0.0.1:8118 to listen-address 0.0.0.0:8118 in /etc/privoxy/config
2. on C, run export http_proxy=http://127.0.0.1:8118; export https_proxy=http://127.0.0.1:8118, or make a proxy_switch.sh:

    #!/bin/bash
    if [ "$1" == "on" ]; then
            export http_proxy=http://B_ip:8118
            export https_proxy=http://B_ip:8118
        echo 'http and https proxy has set to B_ip:8118'
            curl ipinfo.io
    elif [ "$1" == "off" ]; then
            export http_proxy=""
            export https_proxy=""
        echo 'http and https proxy OFF'
    else
        echo 'http_proxy:'
        echo $http_proxy
        echo 'https_proxy'
        echo $https_proxy
            echo 'Please input argument: on,off'
    fi
   	
   

3. run . proxy_swtich.sh on to enjoy C ~
