I have disabled the direct Root login , on all the app server (there are three app servers named , stapp01, stapp02, stapp03) , but after submitting the task. its says . it was not disabled on server 1, as you can see in the attached screenshot … permission to root user is denied.
It’s asking you for a password, which suggests to me that the sshd daemon on stapp01 is still willing to log you in if you supplied a valid password. Is it possible you did not restart the daemon after you updated its configuration on that host?
