If you don't want anyone ever accessing ftp on a given machine, just comment out the ftpd line in /etc/inetd.conf, then, # kill -HUP `cat /var/run/inetd.pid` To reload the file. Note this does not efffect your ability to ftp out of your box. If you are closing out a specific set of hosts while allowing others, or blocking external ftp into a subnet, firewalling is the better way to go. The rule would be something along the lines of, # /sbin/ipfw add deny tcp from <external world> to <protected machine(s)> ftp -- Crist J.
