今天刷票，没想到公司ip被12306封了，看到鱼大的刷票软件支持socks5代理，于是想到用服务器搞个代理试试。
步骤如下

1. 安装 apt-get install dante-server
2. 创建日志文件夹 mkdir /var/log/sockd

3. 修改配置文件 vi /etc/danted.conf 写入以下内容

   logoutput: /var/log/sockd/sockd.log
   internal: 服务器ip port = 1080
   external: 服务器ip
   method: username none
   user.privileged: proxyuser
   user.notprivileged: nobody
   user.libwrap: nobody
   client pass {
       from: 0.0.0.0/0 to: 0.0.0.0/0
       log: connect disconnect
   }
   pass {
       from: 0.0.0.0/0 to: 0.0.0.0/0 port gt 1023
       command: bind
       log: connect disconnect
   }
   pass {
       from: 0.0.0.0/0 to: 0.0.0.0/0
       command: connect udpassociate
       log: connect disconnect
   }
   block {
       from: 0.0.0.0/0 to: 0.0.0.0/0
       log: connect error
   }

4. 启动 /etc/init.d/danted start
5. 检测是否启动成功 netstat -anp | grep 1080

有个问题就是端口暴露出来 会被各种人扫到。。所以千万不能一直开着
