Command to copy client public key to Windows OpenSSH SFTP/SSH server authorized keys file



As an IT administrator, you may want to copy a client's public key to a Windows OpenSSH SFTP/SSH server. This can be accomplished by using the ssh-copy-id command. This command requires the user to have the public key, the client's username, and the Windows OpenSSH SFTP/SSH server's IP address.

To begin, the user must generate a public/private key pair. To do this, the ssh-keygen command is used. This command will generate a key pair and store the private key in a file called \id_rsa,\ and the public key in a file called \id_rsa.pub.\ The user must then copy the public key file, \id_rsa.pub,\ to the Windows OpenSSH SFTP/SSH server.

Once the public key file is on the server, the user must then use the ssh-copy-id command to copy the public key to the Windows OpenSSH SFTP/SSH server's authorized_keys file. This command requires the following arguments:

1. The client's username

2. The IP address of the Windows OpenSSH SFTP/SSH server

3. The path to the public key file, \id_rsa.pub\

The command should look like this:

ssh-copy-id [client username]@[IP address] -i [path to public key file]

Once the command is executed, it will copy the public key to the authorized_keys file on the Windows OpenSSH SFTP/SSH server. This will allow the user to authenticate to the server using the public/private key pair.

In summary, the ssh-copy-id command is used to copy a client's public key to a Windows OpenSSH SFTP/SSH server's authorized_keys file. The user must generate a public/private key pair and copy the public key file to the server before executing the command. The command requires the client's username, the IP address of the server, and the path to the public key file. Once the command is executed, the public key will be copied to the authorized_keys file and the user will be able to authenticate to the server using the public/private key pair.
