ftpshut(8)            MAINTENANCE COMMANDS             ftpshut(8)

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 dis-
     abled.  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 connec-
     tions will be  disconnected.   This  time  may  be  adjusted
     through the -d flag.

     The [ warning-message ... ] will be formatted to be 75 char-
     acters  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
