NOLOGIN(5)                 Linux Programmer's Manual                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)
