NAME    [Toc]    [Back]

       screenmode - Enable or disable gateway screening

SYNOPSIS    [Toc]    [Back]

       /usr/sbin/screenmode [on | off]

DESCRIPTION    [Toc]    [Back]

       The screenmode command enables or disables gateway screening
 if the argument is on or off, respectively.   See  the
       screen(2)  reference  page for more information on gateway
       screening.

       When no argument is  supplied,  screenmode  indicates  the
       state of gateway screening as on or off.

       In  order  to  avoid  packets  being  forwarded before the
       screend program has been started, screenmode should be run
       before  configuring  any  interfaces, other than the first
       interface on the system (which might be needed during  the
       bootstrap sequence).

       Only the superuser can change the state.

NOTES    [Toc]    [Back]

       If gateway screening is disabled while screend is running,
       the daemon might exit.

ERRORS    [Toc]    [Back]

       If an unauthorized user tries  to  change  the  state,  an
       error message is displayed.
