 * 大功告成，然后你就可以开始和本机的:4455端口通信，数据都被自动转发到远端，如同连接到www.yourserver.com:4455一样。 Then you can start communicating with the local: 4455 port, the data is automatically forwarded to the remote, as you connect to www.yourserver.com:4455.
 
 # Test
-测试加速效果，服务器位于aws Korea，下载centos镜像[centos jp mirror](http://ftp.riken.jp/Linux/centos/8/isos/x86_64/CentOS-8-x86_64-1905-dvd1.iso)，直接wget、通过shadowsocks wget、通过pingtunnel wget的结果如下。
