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?
