NAME
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 connections, and deny new connections. The com-
mand creates a control file as /etc/shutmsg to inform proftpd processes about an impending
shutdown.
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 for-
mat.
-R Instructs ftpshut to remove the /etc/shutmsg file, restoring proftpd to its nor-
mal 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 dis-
abled. If the -l option is not specified, a default of 10 minutes (or immedi-
ately, 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 fol-
lowing magic cookies, which will be replaced as follows before being sent to new
or existing connections:
%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 stand-
alone 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.
