Specify User:

Ssh-l Root 192.168.0.11

If you have modified the SSH login port, you can:

Ssh-p 12333 192.168.0.11

Ssh-l Root-p 12333 216.230.230.114

Vim/etc/ssh/sshd_config

Locate #port 22, remove the comment, and modify it to a five-bit port:

Port 12333

Find #permitrootlogin Yes, remove the comment, and modify it to:

Permitrootlogin No
