Name

       ftpshut - close down the ftp servers at a given time

Syntax

       ftpshut [ -V ] [ -l min] [ -d min] time [ warning-message ... ]

Description

       The  ftpshut  command  provides  an automated shutdown procedure that a
       superuser can use to notify ftp users when the ftp server  is  shutting
       down.

       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
       format.

       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
       disconnected.  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
       ftpaccess file.

       The following magic cookies are available:
           Cookie      Description
             %s      time system is going to shut down
             %r      time new connections will be denied
             %d      time current connections will be dropped
             %C      current working directory
             %E      the maintainer’s email address as defined in ftpaccess
             %F      free space in partition of CWD (kbytes)
                     [not currently supported on all systems]
             %L      local host name
             %M      maximum allowed number of users in this class
             %N      current number of users in this class
             %R      remote host name
             %T      local time (form Thu Nov 15 17:12:42 1990)
             %U      username given at login time

Restrictions

       You can kill the servers only between now and 23:59,  if  you  use  the
       absolute time.
