NAME
ftpshut - shut down all proftpd servers at a given time
SYNOPSIS
ftpshut
[
-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 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 second form indicates an
exact time of day, using a 24-hour clock format.
- -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 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 (of 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.
