Im following an RHCSA training course and to disable root I need to set PermitRootLogin to no in the /etc/ssh/sshd_config file and restart sshd using systemctl. I've done all this and can still login as root. Can anyone tell me what to do? Thanks.
Output of ps:
root 836 1 0 14:36 ? 00:00:00 sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups
root 3929 2956 0 15:03 pts/0 00:00:00 grep --color=auto ssh
