ssg-copy-id 192.168.10.10
have passed after the last secret key file server. Now the service side of vim / etc / ssh / sshd_config, found no change PassworfAuthentication
Ssh restart the program. Now with xshell login, login not, because there is no public key file. While wearing a client public key file can be logged.
