frpc的配置文件已经说清楚了，用别人的东西，一定要看清文档。

# [common] is integral section
[common]
# communication protocol used to connect to server
# now it supports tcp and kcp and websocket, default is tcp
protocol = tcp

# 'ssh' is the unique proxy name
# if user in [common] section is not empty, it will be changed to {user}.{proxy} such as 'your_name.ssh'
[ssh]
# tcp | udp | http | https | stcp | xtcp, default is tcp
type = tcp

好的，感谢，也就是底层使用kcp，在云端看到的类型还是tcp是吗？目前这个问题已经解决，但是存在使用kcp时rdp连接被拒绝的情况，切换为tcp又可以使用，另外请问，websocket有何特性？win10如何使用让frpc同时运行两个实例连接不同的服务器？谢谢！

底层通信可选 kcp 协议
复制一份，在不同的目录运行就行了
