You can disable root SSH login by editing /etc/ssh/sshd_config, setting PermitRootLogin to no, and then restarting ssh:
sudo service ssh restart
Hello there,
By default on new Ubuntu servers, the PermitRootLogin is set to yes. So you can search only for PermitRootLogin in the sshd_config.
To disable root login you have to change this line:
PermitRootLogin yes
To:
PermitRootLogin no
However keep in mind that by default, on Ubuntu, password authentication is already set to no:
PasswordAuthentication no
Once you make a change to the sshd_conf file you need to also restart the SSH service:
systemctl restart sshd
Hope that this helps!
Allow only certain users to ssh
- Edit this file: /etc/ssh/sshd_config
- At the bottom write: AllowUsers <your name>@<your ip address> ie. AllowUsers henry@173.58.33.1
