netstat -ano | findstr 21868

本地转发：

ssh -L [LOCAL_IP:]LOCAL_PORT:DESTINATION:DESTINATION_PORT [USER@]SSH_SERVER

• [LOCAL_IP:]LOCAL_PORT - The local machine IP address and port number. When LOCAL_IP is omitted, the ssh client binds on the localhost.
• DESTINATION:DESTINATION_PORT - The IP or hostname and the port of the destination machine.
• [USER@]SERVER_IP - The remote SSH user and server IP address.

ssh -L 5901:127.0.0.1:5901 -N -f user@remote.host

The -f option tells the ssh command to run in the background and -N not to execute a remote command. We are using localhost because the VNC and the SSH server are running on the same host.

远程转发：

ssh -R [REMOTE:]REMOTE_PORT:DESTINATION:DESTINATION_PORT [USER@]SSH_SERVER

• [REMOTE:]REMOTE_PORT - The IP and the port number on the remote SSH server. An empty REMOTE means that the remote SSH server will bind on all interfaces.
• DESTINATION:DESTINATION_PORT - The IP or hostname and the port of the destination machine.
• [USER@]SERVER_IP - The remote SSH user and server IP address.

ssh -R 8080:127.0.0.1:3000 -N -f user@remote.host

The command above will make the ssh server listen on port 8080, and tunnel all traffic from this port to your local machine on port 3000.

执行命令

查询当前激活信息/系统版本（确保是支持KMS的版本）：
slmgr /dlv

安装对应GVLK密钥（如果是从VLSC下载VL版本已经内置，不需要安装）
注:VL版本的镜像文件名是SW_DVD开头。MSDN下的是测试版本不是VL版本。
slmgr /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx

设置KMS服务器地址
slmgr /skms kms.example.com

手动执行激活请求(KMS服务正常的话，手动点立即激活一样效果，不点过一段时间也会自己请求)
slmgr /ato

查询过期时间
slmgr /xpr
