PermitRootLogin no still allows root login via SSH
I have updated PermitRootLogin in /etc/ssh/sshd_config to no and issued a service ssh restart (multiple times) and I can still login via SSH as root using a public key. This should be blocked correct?
I have read the related Q&As here and various others from a Google Search. As far as I can tell I’ve done the right thing but I can still login.
root@infra:~# cat /etc/ssh/sshd_config | grep PermitRootLogin PermitRootLogin no # the setting of "PermitRootLogin yes root@infra:~#
Restarting ssh returns no errors, etc.
root@infra:~# service ssh restart root@infra:~#
PasswordAuthentication is also set to no (although root never had a password – started with a pub key installation) and for good measure UsePAM is set to no.
Love any suggestions!
