客户端连接命令问题

[mywwq]

./ngrokc -SER[Shost:ngrok.redsaefdq.link,Sport:3010] -AddTun[Type:tcp,Lhost:localhost,Lport:23,Rport:3020,Sdname:test1]

tcp:{"Type":"NewTunnel","Payload":{"ReqId":"EIGNW","Url":"tcp://ngrok.redsaefdq.link,Sport:3010","Protocol":"tcp","Error":""}}
Add tunnel ok,type:tcp url:tcp://ngrok.redsaefdq.link,Sport:3020

这个tcp连接加上Sdname为什么没起作用

另外，客户端A向ngrok服务器映射自己的23端口为其他比如说3030，其他客户端telnet <服务器ip> 3030为什么总是失败
telnet ngrok.redsaefdq.link 3020
Trying XX.XXX.XXX.XXX ...
Connected to ngrok.redsaefdq.link.
Escape character is '^]'.
Connection closed by foreign host.
