I use SSH to communicate with my Raspberry Pi (server) from my laptop (Putty client). I would like to disable root SSH login. I change the value of "PermitRootLogin" to no in the /etc/ssh/sshd_config. I restart ssh service via the cmd "sudo service ssh restart"
But, on Putty, I can always login with root password.
How can I disable root ssh login ?
Thx !
You can allow or deny specific users in /etc/ssh/sshd_config by setting
# whitelist
AllowUsers pierrot arlecchino
# blacklist
DenyUsers innamorati pantalone
and then run sudo systemctl restart ssh. Be advised: Before you deny users, especially the default user "pi", make sure you can login by SSH with the allowed user, else you risk to lock out yourself!
