Steps to reproduce
1、 在mac上运行 go run cmd/frpc/main.go -c ././conf/frpc.toml 并连接服务端成功
2、在服务器执行ssh -oPort=6000 test@127.0.0.1

@vikii0210 commented on GitHub (May 11, 2024):
frps.toml 最下方把这个加进去就可以了
allowPorts = [
{ single = 22}
]
@huoyanyanyi1 commented on GitHub (May 11, 2024):
还是一样的报错
@huoyanyanyi1 commented on GitHub (May 11, 2024):
执行ssh -oPort=6000 test@127.0.0.1
服务端报错日志：
kex_exchange_identification: Connection closed by remote host
Connection closed by 127.0.0.1 port 6000
