ftpshut(8)                                             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  proce-
       dure 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 connec-
       tions 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 connec-
       tions 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.
