Try editing the /etc/services and commenting out the line for ftp/21. Then refresh inetd. This should keep the system from listening on port 21. Also, you could use /etc/inetd.conf to filter out the ftp traffic from all hosts during the time frame you are looking for.

If you are running ws-ftp it's pretty easy, just add the following line to your /etc/ftpaccess file:

shutdown /etc/shutmsg

You can create the /etc/shutmsg file with a custom message in it to suit you.

Else, as crowe said, either comment the port out in the /etc/services file, ot comment the process out in the /inetd.conf file. This will require a SIGHUP of the inetd process to make effective.

Absi,

Te scripts below will achieve what you want:

#!/bin/ksh
#
# Comment out ftp from /etc/inetd.conf
/usr/sbin/chsubserver -r inetd -C /etc/inetd.conf -d -v 'ftp' -p 'tcp6'
refresh -s inetd

#!/bin/ksh
#
# Comment in ftp from /etc/inetd/conf
/usr/sbin/chsubserver -r inetd -C /etc/inetd.conf -a -v 'ftp' -p 'tcp6'
refresh -s inetd

Execute them via cron and voila.

Hope that helps PSD
