NAME

       nologin - prevent unprivileged users from logging into the system

DESCRIPTION

       If  the  file  /etc/nologin exists and is readable, login(1) will allow access only to root.  Other users
       will be shown the contents of this file and their logins will be refused.  This provides a simple way  of
       temporarily disabling all unprivileged logins.
