[lug] FTP services - disarming daemon

Did you look at /etc/inetd.conf? That's where inetd gets information on
what to launch for an incoming connection. It uses /etc/services to map
the port number to the service that is named in /etc/inetd.conf. You'll
also have to kill -HUP inetd for changes to take place.
In response to a suggestion about hosts.allow, you should probably use
ipchains rather than hosts.allow and hosts.deny. My reasoning is that if
@home just attempts to find a listener, hosts.allow won't stop the
listening, it'll just break an illegal connection. For example, if you
telnet from a machine that is denied, you'll see the connection made and
then dropped. That doesn't happen when you attempt to telnet to a windows
machine. You just sit there and nothing happens. That's what you need to
emulate, and that's what you'll get when you use ipchains rather than
Ready for the flames....
