ftpshut - shut down all proftpd servers at a given time SYNOPSIS
ftpshut [ -R ] [ -l min ] [ -d min ] time [ warning-message ] DESCRIPTION
The ftpshut command provides an automated shutdown procedure that a superuser can use to automagically disconnect current proftpd connec- tions, and deny new connections. The command creates a control file as /etc/shutmsg to inform proftpd processes about an impending shut- down. OPTIONS
time The time at which the ftp servers will be brought down. It may be the word `now', indicating an immediate shutdown, or a future time in one of two formats: +number or HHMM. The first form brings the servers down in number minutes, while the second form indicates an exact time of day, using a 24-hour clock format. -R Instructs ftpshut to remove the /etc/shutmsg file, restoring proftpd to its normal service. If this option is used, this will be the only operation performed by ftpshut -l min Specifies the number of minutes before shutdown that new ftp access will be disabled. If the -l option is not specified, a default of 10 minutes (or immediately, if less than 10 minutes remains until shutdown) is used. -d min Specifies the number of minutes before shutdown that existing ftp connections will be disconnected. If the -d option is not specified, a default of 5 minutes (or immediately, if less than 5 minutes remains until shutdown) is used. warning-message Optionally provide a message which will be sent to new connections (if denied) and existing connections (when disconnected). The message can contain the following magic cookies, which will be replaced as follows before being sent to new or existing connec- tions: %s time proftpd is being shut down %r time new connections will be denied %d time current connections will be dropped %C current working directory (where applicable) %L local host name (or virtualhost name) %R remote host name %T local time (format Thu Nov 15 17:12:42 1990) %U username given at login time CAVEATS
Proftpd servers can only be shutdown via ftpshut if a master daemon is running in standalone mode. Servers running in inetd mode will honor the shutdown message file created by ftpshut, however currently running servers may be chroot(2)ed, and unable to read the shutdown message control file. It is possible to set an absolute shutdown time which is earlier than the current time. If this is the case, proftpd will not shutdown until the indicated time on the following day. FILES

ftpshut(1M) System Administration Commands ftpshut(1M) NAME
ftpshut - close down the FTP Servers at a given time SYNOPSIS
ftpshut [-V] [-v] [-l min] [-d min] time [warning-message...] DESCRIPTION
The ftpshut command provides an automated shutdown procedure that the superuser can use to notify FTP users when the FTP Server is shutting down. Ten minutes before shutdown, or immediately if the value of time is less than ten minutes, any new FTP Server connections will be disabled. You may adjust the shutdown of new FTP Server connections by means of the -l option. Five minutes before shutdown, or immediately if the value of time is less than five minutes, all current FTP connections will be discon- nected. You may adjust the shutdown of current FTP connections by means of the -d option. The ftpshut command creates shutdown message files that the FTP Server uses to determine when to shutdown. Separate shutdown message files are created in the anonymous and virtual host FTP Server areas, in addition to the system wide shutdown message file. Once the shutdown occurs, the server continues to refuse connections until the appropriate shutdown message file is removed. This normally is done by using the ftprestart(1M) command. The location of the shutdown message file is specified by the shutdown capability in the ftpaccess file. The following magic cookies are available: %s The time system is going to shut down. %r The time new connections will be denied. %d The time current connections will be dropped. %C The current working directory. %E The maintainer's email address as defined in the ftpaccess file. %F The free space in the partition of CWD, in kilobytes. %L The local host name. %M The maximum allowed number of users in this class. %N The current number of users in this class. %R The remote host name. %T The local time (form Thu Nov 15 17:12:42 1990). %U The username given at login time. OPTIONS
The ftpshut command supports the following options: -V Display program copyright and version information, then terminate. -d min The time ahead of shutdown, in minutes, that existing connections will be disconnected upon completion of their current or next (if idle) FTP request. -l min The time ahead of shutdown, in minutes, that new connections will be refused. -v Verbose. Output the pathname of the shutdown message files created. OPERANDS
The ftpshut command supports the following operands: time The time at which ftpshut will bring the FTP Servers down. time can have a value of now, which indicates an immedi- ate shutdown. Alternatively, time can specify a future time in one of two formats: +number or HHMM. The first form brings the FTP Server down in number minutes. The second brings the FTP Server down at the time of day indicated, using a 24-hour clock format. When using the absolute time format, you can only specify times between now and 23:59. warning-message The message to display that warns of the imminent shutdown. The warning-message will be formatted at 70 characters wide. ftpshut knows the actual string length of the magic cookies. If no warning-message is supplied, the default message "System shutdown at %s" is used. EXIT STATUS
The following exit values are returned: 0 Successful completion. >0 An error occurred. FILES
