Recently, there is a requirement that after the server executes an instruction, it needs to back up the generated data to windows. It's not easy to check on the Internet. Some need to write a script to run in windows, but this application does not need windows operation. Instead, it monitors the operation of the server and backs up directly after executing an instruction.
Configure the ssh service on the server
This general server has been configured. If it is not configured, you can refer to it How to configure and install SSH service under Linux system - system operation and maintenance - Yisu cloud (yisu.com) Method configuration on
After the configuration is completed, enter SSH keygen and enter all the way. When y/n is encountered, yes will be displayed. The following description is OK.

Start ssh service in Windows 10
reference resources Install OpenSSH | Microsoft Docs Follow the instructions in to install and start the ssh service directly.
It should be noted that it is not enough to enter SSH in power shell to display the following contents. The following display shows that the computer has installed SSH client, so you need to install ssh server according to the above documents, because my application sends files from the server to Windows, so Windows is equivalent to the server at this time.

The above two have installed and started the ssh services on the server and Windows normally. After a long time, you can test whether the ssh connection is normal. The following attempts are to use the IP of Linux is 192.168.0.119 and the IP of local Windows is 18.104.22.168

Similar to the above display, it indicates that Windows is connected to Linux normally

As shown in the above figure, the test shows that the connection between Linux and windows is normal, and the ssh service of windows is normal. At this time, you can test the file transfer function
fred@fred-VirtualBox:~/ssc338_v20211022$ scp quickBuild.sh Fred@192.168.0.103:C:/Users/Fred/Documents/Downloads Fred@192.168.0.103's password: quickBuild.sh 100% 1978 4.6MB/s 00:00 fred@fred-VirtualBox:~/ssc338_v20211022$
After entering the above command, it means OK to find the file in the specified location of Windows. Note that when writing the path of Windows, use / can't use \, otherwise it will be copied to Disk C, and the file name will be changed to a pile of string superposition

SSH pass solves the problem of entering a password when canceling scp input
sudo apt install sshpass
Transfer files through sshpass
sshpass -p 123456 scp quickBuild.sh Fred@192.168.0.103:C:/Users/Fred/Documents/Downloads
The parameter - p is followed by the password
After all the above operations are completed, you can detect an instruction in the script, and then add the transmission instruction.
