Disable SSH root login

Disabling root login via SSH

Disabling SSH root login will add an extra layer of security. It would be more secure to brute force
attacks or in case your password is stolen.

1. Create a non-root user
   
   adduser username
passwd username
   
   
2. Open the ssh configuration file with your editor.
   
   vi /etc/ssh/sshd_config
   
   
3. Add the line “PermitRootLogin no.” Or uncomment the line "#PermitRootLogin yes" and
   change yes to no.
   
   #LoginGraceTime 2m
#PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10
PermitRootLogin no
   
   
4. Save and exit the file.
5. Restart the ssh service
   
   systemctl restart sshd.service
