- .SH Description
- The
- .B ftpshut
- command
- provides an automated shutdown procedure that a superuser
- can use to notify ftp users
- when the ftp server is shutting down.
- .PP
- The
- .B -V
- option causes the program to display copyright and version information, then
- terminate.
- .PP
- The
- .I time
- is the time at which
- .B 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:
- .I + number
- or
- .I HHMM.
- The first form brings the ftp servers down in
- .I number
- minutes.
- The second brings the ftp servers down at the time of day indicated,
- using a 24-hour clock format.
- .PP
- Ten minutes before shutdown, or immediately if
- .B ftpshut
- is timed for less than ten minutes, new ftp
- access will be disabled. This time may be
- adjusted through the -l flag.
- .PP
- Five minutes before shutdown, or immediately if
- .B ftpshut
- is timed for less than five minutes, all
- current ftp connections will be disconnected.
- This time may be adjusted through the -d flag.
- .PP
- The
- .I [ warning-message ... ]
- will be formatted to be 75 characters wide.
- .B ftpshut
- knows about the actual string length of
- the magic cookies.
- .PP
- 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
- .I shutdown
- stanza in the
- .B ftpaccess
- file.
