Yes, but some time it is down, or the nameserver into resolv.conf is not
set.

Is a internal DNS, the local network in not property configured, the DNS
is not use. In this scenario the version fc[1-5] work great.

Now I have check (on telnet server) to point the nameserver to 127.0.0.1
and start bind (whitout configure it). The connection from a telnet
client now work (without the nsswitch.conf modify). The problem is
disappeared.

Then:

On fc6 the nameserver must set, and must point to a existent nameserver.
If nameserver is NOT set, or is set to a IP down or a generic host (not
a nameserver) the xinetd connection (like telnet ) do not work.

It is therefore? Is this right?

Thanks to all
