I created a new user lets call it X.
I disallowed the root login from SSH, so I login with X and after I call "#su root" command.
But when I login that way, I can't use some commands like "service".
I can access all the files, I can even change the sshd_config file but some commands say "not found".
Do I need to get X to a group? Or make it some priveledges etc? What should I have to do to run this free of problems?
