Shut down all proftpd servers at a given time
ftpshut [ -R ] [ -l min ] [ -d min ] time [ warning-message ]
The ftpshut command provides an automated shutdown procedure that a superuser can use to automagically disconnect current proftpd connections, and deny new connections. The command creates a control file as /etc/shutmsg to inform proftpd processes about an impending shutdown.
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.
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
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.
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.
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 connections:
time proftpd is being shut down
time new connections will be denied
time current connections will be dropped
current working directory (where applicable)
local host name (or virtualhost name)
remote host name
local time (format Thu Nov 15 17:12:42 1990)
username given at login time
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.
