Disable root connect to server by ssh-client.

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.
