Hi, I am running RH9 with Bind 9.2.1 and DHCP (isc-dhcpd-V3.0pl9). I have configured DHCP to automatically update the DNS with the appropriate ip address and FQDN, and it works fine for the A records, but when it tries to add an entry into the xxx.xxx.xxx-addr-arpa. File it fails. I have scoured the various how-to's, man pages and the various faq e-mail groups etc, and I can not find anything that gives me a clue where to look, so I now come to the community to appeal for help. NOTE: This is a class B subnet with 1024 addresses per subnet, starting at x.x.128.0 and ending on x.x.131.255 Regards Enrico This is the error I receive. ============================ Jan 31 12:43:30 jbpn1 dhcpd: if IN A devel.jbpn. domain doesn't exist add 216000 IN A devel.jbpn. 172.16.129.203 add 216000 IN TXT devel.jbpn.
