I am configuring my server to prevent hacker bruteforce attacks by disabling root login from ssh: by setting PermitRootLogin no in file /etc/ssh/sshd_config.
This way I created new user (let's call it user) with secret name.
But when I am changing file etc/passwd by setting user's GID and UID to root's "0" value, it is not possible to log in (due sshd_config).
But how can I make user root-like but keep safe ssh logining?
