screenmode(8)screenmode(8)NAMEscreenmode - Enable or disable gateway screening
SYNOPSIS
/usr/sbin/screenmode [on | off]
DESCRIPTION
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
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.
