NOLOGIN(5)                (2017-09-15)                 NOLOGIN(5)

     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.

     FILES
          /etc/nologin

     SEE ALSO
          login(1), shutdown(8)
