AIX Tip

Sometimes it is necessary to disable users from logging into a system, such as when doing certain types of administration work. To disable user login in AIX, create the file /etc/nologin. When a non-root user attempts to login, the system blocks the login and displays the contents of the /etc/nologin file. To enable user login, erase the /etc/nologin file.
