一个基于erlang的Socks5代理服务器程序：make-proxy（这个程序很不错，非常的robust)

Intro

This project can take you through a Firewall via Socks5 proxy.

Features

with the great erlang, the project has the following features:

• socks5 / http proxy. (https not supported)
• Robustness. never down.
• Scalable. handle thousands requests at the same time easily.
• Fast.
• Lightweight. only takes less than 20MB memories.

Running status

In my daily use, (1 cpu, 512MB RAM VPS)

• Play 2 youtube 1080P video at the same time, It only takes 16MB memories.

1. proxy client is running at your local computer.
   It receive your app (like a browser) request, encrypt the data, send to proxy server
2. proxy server receive the request from proxy client, decrypt it, and sent to the target host.
3. proxy server got the response from target host, then encrypt response, send back to proxy client.
4. proxy client decrypt response received from proxy server, and send to local app.
5. the circle done.

Usage

Server side

1. git clone https://github.com/yueyoum/make-proxy.git or directly download.
2. cd make-proxy
3. cp server.config.example server.config,

   server.config

   • port. which port that the server listen on
   • key. key to encrypt/decrypt data 16bytes
4. make server

   （注意：如果运行make server遇到错误，其实是这程序自带的rebar可执行文件有问题。我把它删除了。
   

   root@AR:~/make-proxy/server# ls
   rebar rebar.config src
   root@AR:~/make-proxy/server# rm rebar
   root@AR:~/make-proxy/server# ls
   rebar.config src
   root@AR:~/make-proxy/server# rebar compile
   这样，输出的结果里没有错误。

   在客户机器里，也是类似做法：
   yudeMacBook-Air:make-proxy brite$ ls
   ChangeLog client.config start_client.sh
   LICENSE client.config.example start_server.sh
   Makefile include utils
   README.md server
   client server.config.example
   yudeMacBook-Air:make-proxy brite$ cd client
   yudeMacBook-Air:client brite$ ls
   rebar rebar.config src
   yudeMacBook-Air:client brite$ rm rebar
   yudeMacBook-Air:client brite$ ls
   rebar.config src
   yudeMacBook-Air:client brite$ rebar compile
   这样，输出的结果里也没有错误。 另外， key 必须是 16字节，

   也就是说，得是一个 包含16个 char 的字符串，比如把 key 设置成 1234567890abcdef这样。

   rebar的安装见此文http://briteming.blogspot.jp/2015/11/shadowsockserlangshadowsocks-erlang.html的“rebar环境的搭建”部分）
5. ./start_server.sh （建议运行erl -pa server/ebin -config server +K true -s make_proxy_server start -detached即可。）

Local side

1. same as the Server side, checkout the code.
2. cd make-proxy
3. cp client.config.example client.config

   client.config

   • remote_addr. IP of the compute where make-proxy server runs
   • remote_port. PORT that make-proxy server using. SAME as the defination of server.config.
   • local_socks5_port. this port is used for socks5 proxy.
   • local_http_port. this port is used for http proxy.
   • key. key to encrypt/decrypt data. this MUST AS SAME AS the defination of server.config.
4. make client
5. ./start_client.sh (建议运行：
   
   

   erl -pa client/ebin -config client +K true -s make_proxy_client start -detached即可。我运行

   ./start_client.sh时，遇到错误）

Now, you can set your apps (e.g. Browser) Using socks5 proxy.

IP = 127.0.0.1 PORT = 7070 (if not changed in the client.config)

TODO

1. Support Socks5 Username/Password Authorize
