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, change in /etc/passwd the uid/gid to 0:0. But the problem is, that once I block ssh access to user root by changing in sshd_config the line PermitRootLogin yes to no..., all other users that share the 0:0 uid/gid also loose access via ssh to the box. Help please..., or guide in right path to achieving this... ***the box does not have internet access, so, installing sudo/sudoer to manage users it's not possible***
