Hello!

That's not necessarily true -- xinetd CAN use tcp_wrappers (tcpd),
and how it's configured by default depends on distro and
type/method of install.

On one of my systems (Mandrake 7.2), xinetd "out of the box" has
config files for each service, and they call the tcpd binary for the
service.

For example, this is the "telnet" config file (/etc/xinetd.d/telnet):

#################################################
service telnet
{
        flags = REUSE
        socket_type = stream
        wait = no
        user = root
        server = /usr/sbin/in.telnetd
        log_on_failure += USERID
}
#################################################

...and it most certainly DOES query hosts.allow/hosts.deny.

Hope that I do not speak out of turn...

-P.W.T.

(that service is disabled, of course ^_^ )
