etc/shutdown - server shutdown control file
If the file etc/shutdown is present it describes when a HylaFAX server
is to be shutdown and may contain a descriptive message to return to
clients explaining the reason for the shutdown. This file is used by
the hfaxd(8) program.
The file has the following format:
<year> <month> <day> <hour> <minute> <deny> <disconnect>
<shutdown message text>
The first line defines the date and time the server should be shutdown
and the time preceding at which unprivileged clients should be denied
service or disconnected; these fields are described in more detail
below. Any lines that follow the first are taken as the text of a
message to return to clients when notifying them of a scheduled
shutdown or when denying them service.
<year> The decimal year; e.g. 1996.
<month> The decimal month; e.g. 10 for October.
<day> The decimal day of the month in the range [1..31].
<hour> The decimal hour since midnight; in the range [0..23].
<minute> The decimal minute after the hour; in the range [0..59].
<deny> The time prior to the shutdown time at which to deny service
to unprivileged clients. This value is specified as decimal
number in the form HHMM; e.g. 130 for 1 hour and 30 minutes.
Time time prior to the shutdown time at which to disconnect
unprivileged clients that are logged in to the server. This
