Hi,

  I've my secondary DNS Server that run bind9 version 9.5.0-P2 (from ubuntu 9.10 server)

  Before, I was using the version on ubuntu 8.04 and it was working successfully.

  Yesterday I configure a new '.fr' domain which require a successfull zonecheck and I got the following error :

_____________________________________________________________________
---- fatal ----
f: Server doesn't listen/answer on port 53 for UDP protocol

     * Ref: IETF RFC1035 (p.32 4.2. Transport)

       The DNS assumes that messages will be transmitted as datagrams or in a byte stream carried by a virtual circuit. While virtual circuits can be used for any DNS activity, datagrams are preferred for queries due to their lower overhead and better performance.

     * ns1.ordiworld.fr./2A01:E0B:1:31:240:63FF:FEE5:C74A

I've checked, I can ping6 my server, firewall is correctly configured and I've got this message in the logs which says no ipv6 interface found :
