使用shadowsocks的erlang语言版：shadowsocks-erlang翻墙

首先按此文：在linux vps上安装erlang 搭建erlang and rebar环境。

然后，
  • git clone https://github.com/Yongke/shadowsocks-erlang
    cd shadowsocks-erlang
    rebar compile
    (rebar compile就是编译基于erlang的源码的命令）
    这样shadowsocks-erlang就编译好了。
    （需先安装erlang和rebar,参见本文末尾）
    Erlang OTP(R16B01) and rebar are needed. crypto module in OTP improved a lot in R16B01, but unfortunately, the port which implement this module does not use EVP_* functions. Which means almost all the block cipher method is not compatible with other shadowsocks implementation. default and rc4 method works fine.
  • Client side
    erl -smp auto -config ./local.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached
  • Server side
    erl -smp auto -config ./remote.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached

Configuration

  • Config files
    local.config, remote.config
  • Descriptions
     {shadowsocks,
     [
       {type, local},
       {local_port,1080},
       {server,"VPS_IP"},
       {server_port,8488},
       {password,"你自设的密码"},
       {method,rc4}
     ]}
{type, local} is for client side, {type, remote} is for server side.

 编辑remote.config如下：
...
 {shadowsocks,
  [
   {type, remote},
   {local_port,1080},
   {server,"localhost"},
   {server_port,8488},
   {password,"你自设的密码"},
   {method,rc4}
  ]}
...
然后运行：
erl -smp auto -config ./remote.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached
这样,服务器端就搭建好了。
注意：method的值default一定要改为rc4.

 兼容任何shadowsocks客户端程序，不过加密方式要选择rc4.（在mac上可以使用shadowsocksX这个客户端。)

在mac里，也可像linux vps那样，把shadowsocks-erlang克隆下来，进行编译。当然你一样需先在mac上安装erlang环境和安装rebar.然后，
git clone https://github.com/Yongke/shadowsocks-erlang
cd shadowsocks-erlang
yudeMacBook-Air:shadowsocks-erlang brite$ ls
README.md include log remote.config
ebin local.config rebar.conf src

yudeMacBook-Air:shadowsocks-erlang brite$ rebar compile
这样shadowsocks-erlang就编译好了。编辑local.config文件如下：

{shadowsocks,
     [
       {type, local},
       {local_port,1080},
       {server,"VPS_IP"},
       {server_port,8488},
       {password,"你自设的密码"},
       {method,rc4}
     ]}
然后运行：
erl -smp auto -config ./local.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached
yudeMacBook-Air:shadowsocks-erlang brite$ lsof -i:1080
COMMAND    PID   USER   FD   TYPE            DEVICE SIZE/OFF NODE NAME
beam.smp 57691 brite   13u  IPv4 0x352e3a321ea1a93      0t0  TCP *:socks (LISTEN)
(beam.smp,即erl在监听1080端口，说明erl -smp auto -config ./local.config -pa ./ebin/ -boot start_sasl -s shadowsocks_app start -detached运行成功。
yudeMacBook-Air:shadowsocks-erlang brite$

然后设置浏览器的socks5代理为127.0。0.1:1080，即可翻墙。

使用后，感觉shadowsocks的erlang语言版比shadowsocks的python语言版要robust和快速得多！
