在windows宿主机上使用系统自带的openSSH连接linux。
（本例连接的vmware中centos7）
1. openSSH
1. Check whether the machine is installed
win+R and enter openssh
to jump to the directory where openSSH is located (mine is C:\Windows\System32\OpenSSH).
If not, please install it yourself. Generally, the system comes with it.
2. Configure environment variables
Add the directory where openSSH is located in the system variable path
3. Basic commands
win+R, enter cmd to run, and then enter ssh
to see the optional parameter list displayed in the help option. Generally, you only need to use user@host for connection.

2. Connection
1. Application
cmd input ssh user@localhost (enter your own user and ip address to connect to linux)
If the connection is successful, the following content is displayed:
enter yes, and then enter the password to complete the connection.
2.bug
There are probably two reasons for the bug:
1. The C:\Users\xxxx/.ssh/config file has no permissions, refer to:

2. If this problem occurs when using vscode to connect to linux, the solution: https://zixizixi.cn/windows_vscode_ssh_error_bad-owner-or-permissions
3. Conflict between git ssh and openssh, solution:

4. If it doesn’t work, consider deleting the config file directly (there may be problems with the config file being modified)
I report the Bad owner or permissions on C:\Users\xxxx/.ssh/config problem, which
is actually a conflict between git ssh and openssh. Check the environment variables as follows:
You can also search for git bash with win + s to view the file location. There are three files
ssh_config and sshd_config in etc/ssh in this directory, which are related to the files in the C:\Users\xxxx/.ssh directory. At this point, I found the problem of Bad owner or permissions on C:\Users\xxxx/.ssh/config.
3. Solve bugs
The solution to the configuration conflict between openssh and git ssh:
1. Remove openssh from the environment variable and use git ssh.
2. Use ssh root@loalhost [-F config_file] to manually specify the location of the config file, so you don’t need to remove openssh
Here is the second solution:
Create an openssh_config empty file under C:\Users\xxxx\ (call it anything)
cmd input ssh root@loalhost -F openssh_config, then enter the password
Three, shell tools
Recommend an easy-to-use shell tool windows terminal for easy connection to linux
1. Install

2. Configuration
Start the windows terminal, press and hold (ctrl + , ) to open the settings, and choose to add a new configuration file

3. Startup directory: use the parent process directory
