ftpshut(8) System Manager's Manual ftpshut(8)
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 su-
peruser 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.
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 sec-
ond 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 connec-
tions (if denied) and existing connections (when discon-
nected). The message can contain the following 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 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 con-
trol 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.
