I'm kinda new to linux so bear with me. I followed a tutorial on how to grant root access to other users and what I did was, in /etc/passwd/ I changed the other users' uid/gid to 0:0.
The problem is that once I block ssh access to user root by changing PermitRootLogin to no in sshd_config, all other users that share the 0:0 uid/gid also loose access via ssh to the box.
Help please...The box does not have internet access, or guide in right pathso, installing sudo/sudoer to achieving this..manage users it's not possible. the box does not have internet access, so, installing sudo/sudoer to manage users it's not possible
