ftpshut - close down the ftp servers at a given time
ftpshut [ -V ] [ -l min] [ -d min] time [ warning-message ... ]
The ftpshut command provides an automated shutdown procedure that a
superuser can use to notify ftp users when the ftp server is shutting
The -V option causes the program to display copyright and version
information, then terminate.
The time is the time at which ftpshut will bring the ftp servers down.
It may be the word `now', indicating an immediate shutdown, or specify
a future time in one of two formats: + number or HHMM. The first form
brings the ftp servers down in number minutes. The second brings the
ftp servers down at the time of day indicated, using a 24-hour clock
Ten minutes before shutdown, or immediately if ftpshut is timed for
less than ten minutes, new ftp access will be disabled. This time may
be adjusted through the -l flag.
Five minutes before shutdown, or immediately if ftpshut is timed for
less than five minutes, all current ftp connections will be discon-
nected. This time may be adjusted through the -d flag.
The [ warning-message ... ] will be formatted to be 75 characters wide.
ftpshut knows about the actual string length of the magic cookies.
Running this command will create a file that the server will use to
determine when to shutdown. Once the shutdown has occured, the server
will continue to refuse connections until this file is removed. The
location of this file is specified by the shutdown stanza in the ftpac-
