Well I tried this on Ubuntu Hardy and at least now I'm getting something showing up in tcpdump:<br><br>17:12:27.079892 IP 192.168.101.254.60433 > 192.168.100.2.53: 46870+ PTR? 5.50.168.192.in-addr.arpa.

It looks identical except there is an "authoritive" directive in this one. I have not tried it with that "authoritative" commented out. The updates are still not showing up on the dns server and I would prefer to do this on Red Hat but at least I'm getting something in the tcpdump output.<br>
