After I started my server [FC4], I would be disable root connect to this server by ssh-client. This is solution .
1. Open file /etc/ssh/sshd_config
| # vi /etc/ssh/sshd_config |
2. Uncomment this line has “PermitRootLogin yes” and change yes to no
| : #LoginGraceTime 2m PermitRootLogin no #StrictModes yes : |
3. Restart sshd service.
| # service sshd restart |
4. If you don’t want to disconnect by client (because you connect by ssh-client) you can kill sshd process by use -1 option such as
| # pkill -1 sshd |
this option can help you keep connection between client&server because this command will be kill process -> reload new config -> start sshd process same sshd old process id.
