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 connections 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 connections 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 virtual 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 shutdown 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.
