[lug] FTP services - disarming daemon

[Chip Atkinson]

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
hosts.allow/deny. 

Ready for the flames....
