<H2>DESCRIPTION</H2>
|
|
|
|
The <B>ftpshut</B> 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
|
|
<B>/etc/shutmsg</B> to inform proftpd processes about an impending shutdown.
|

|
|
<DT><B>time</B>
|
|
<DD>
|
|
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: <I>+number</I> or <I>HHMM.</I> The first form brings the
|
|
servers down in <I>number</I> minutes, while the second form indicates an
|
|
exact time of day, using a 24-hour clock format.
|
|
|
|
<P>
|
|
<DT><B>-l min</B>
|
|
<DD>
|
|
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.
|
|
|
|
<P>
|
|
<DT><B>-d min</B>
|
|
<DD>
|
|
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
|

<H2>CAVEATS</H2>
|
|
|
|
Proftpd servers can only be shutdown via ftpshut if a master daemon is running
|
|
in <I>standalone</I> mode. Servers running in <I>inetd</I> 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.
|
|
|
|
<P>
|
|
It is possible to set an absolute shutdown time which is
|
|
<B>earlier</B> than the current time. If this is the case, proftpd will not
|
|
shutdown until the indicated time on the following day.
