System Administration Commands ftpshut(1M)
NAME
ftpshut - close down the FTP Servers at a given time
SYNOPSIS
ftpshut [-V] [-v] [-l min] [-d min] time
[warning-message]...
DESCRIPTION
The ftpshut command provides an automated shutdown procedure
that the superuser can use to notify FTP users when the FTP
Server is shutting down.
Ten minutes before shutdown, or immediately if the value of
time is less than ten minutes, any new FTP Server connec-
tions will be disabled. You may adjust the shutdown of new
FTP Server connections by means of the -l option.
Five minutes before shutdown, or immediately if the value
of time is less than five minutes, all current FTP connec-
tions will be disconnected. You may adjust the shutdown of
current FTP connections by means of the -d option.
The ftpshut command creates shutdown message files that the
FTP Server uses to determine when to shutdown. Separate
shutdown message files are created in the anonymous and vir-
tual host FTP Server areas, in addition to the system wide
shutdown message file. Once the shutdown occurs, the server
continues to refuse connections until the appropriate shut-
down message file is removed. This normally is done by using
the ftprestart(1M) command. The location of the shutdown
message file is specified by the shutdown capability in the
ftpaccess file.
The following magic cookies are available:
%s The time system is going to shut down.
%r The time new connections will be denied.
%d The time current connections will be dropped.
%C The current working directory.
