NAME

  screenmode - Enable or disable gateway screening

SYNOPSIS

  /usr/sbin/screenmode [on | off]

DESCRIPTION

  The screenmode command enables or disables gateway screening if the argu-
  ment 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

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

ERRORS

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