The DHCP server said only make this change if there is nothing at the name and there was something at the name. This is done to prevent DHCP overriding static entries. > Feb 28 16:17:11 nzhmlsrv01 named[3363]: client 192.168.64.242#40426: > view interenal: updating zone 'et.endace.com/IN': update unsuccessful: > nzhmlwks0091.et.endace.com/TXT: 'RRset exists (value dependent)' > prerequisite not satisfied (NXRRSET) The DHCP server said only make this change if the TXT record that says I did the last change exists and it doesn't. This is done to prevent the DHCP server changing/removing records it didn't add. The TXT record was used to encode what is now encoded in the DHCID record. See http://www.ietf.org/rfc/rfc4701.txt > What are these errors and how do I resolve them ? If you are certain that there is not a collision removing all the records at the name will permit DHCP to add new record. [email protected] would be a good place to discuss what DHCPD is trying to do. > Thanks > > Greg > _______________________________________________ > Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe > from this list > > bind-users mailing list > [email protected] > https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: [email protected] _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list [email protected] https://lists.isc.org/mailman/listinfo/bind-users
