Деактивиране на root
може да се ползва sudo или да махнем ssh root login
vi /etc/ssh/sshd_config
#LoginGraceTime 2m #PermitRootLogin no #StrictModes yes #MaxAuthTries 6
Make the line look like this to disable logging in through ssh as root.
PermitRootLogin no
Now you’ll need to restart the sshd service:
/etc/init.d/sshd restart
