Pointer un ndd EuroDns vers O2switch

Webconsult

Nouveau WRInaute
Bonjour à tous,

Je possède un nom de domaine .lu que j'ai acheté chez EuroDns ainsi qu'une offre hébergement chez o2switch.

J'aimerais faire pointer ce ndd chez mon hébergeur ce qui parait a priori facile.

Malheureusement, et ce malgré avoir suivi les instructions à la lettre et répéter plusieurs fois les manipulations, cela ne fonctionne pas et les 2 prestataires se renvoient la balle, je n'ai même plus de réponses de la part de o2switch.

La réponse EuroDns :

Dear Customer,

Important information regarding your domain webconsult.lu.

The nameservers you have declared are more than likely misconfigured:

ns1.o2switch.net, 109.234.160.5
ns2.o2switch.net, 109.234.161.5


The following error(s) occured:

errors=4, warnings=0, informational=0

Error : [UDP] Query failed for nameserver 'ns2.o2switch.net' at address '109.234.161.5' (Refused)
Error : [UDP] Query failed for nameserver 'ns1.o2switch.net' at address '109.234.160.5' (Refused)
Error : No working authoritative nameserver found
Error : At least 2 nameservers required

Once you have corrected the problem on your DNS servers, you can then log into your EuroDNS account and re-enter the information of your nameservers.


Best regards,

La réponse O2switch

Bonjour,

J'avoue ne pas savoir quoi vous répondre ca les deux serveurs sont bien ouverts sur le port 53, en udp. D'autres LU réservés par exemple chez OVH ou Bookmyname fonctionnent sans problème.

Cordialement
Alexandre

Arpès avoir relancé plusieurs fois les deux prestataires, je n'ai toujours pas trouvé de solution ...

Quelqu'un aurait il une piste de solution ?

Merci d'avance

Bonjour,

Je suis Isabelle, sales account manager chez EuroDNS.
Avez vous trouvé une solution à votre problème depuis la semaine dernère ou désirez vous encore de l'aide ?
Vous pouvez me contacter à l'adresse ibergen@eurodns.com

Il est également possible de trouver de l'aide sur le site du registre à l'adresse : http://www.dns.lu/en/support/checking-nameservers/

Voici déjà quelques informations :

Technical Description

Before a domain name can be activated in the .lu zone, the name servers responsible for the domain name requested must be operational and configured correctly. The following five points are checked before a server is approved:

the name servers should answer authoritatively for the requested domain;
the name provided for the name servers must not be an alias (i.e. the data field of a CNAME record);
the name of the name server must correspond to the IP address provided;
the name server must be listed as a name server (IN NS record) for the requested domain;
the names of the name servers must comply with the definitions given in the RFCs.
Technically, two different configurations are possible.

a) The name server is part of the domain it is serving (e.g. ns1.dns.lu is part of the dns.lu domain). A type A query requesting the name of the name server is sent to the server’s IP address. The response from the server must be authoritative, contain the server’s IP address and must not return the server name in the form of an alias. The second stage in the validation involves an NS query being sent to the server’s IP address for the domain name in question. The response to this query must also be authoritative and contain the name of the name server.

b) The name server is not part of the domain it is serving. An NS query for the domain is sent to the IP address obtained through normal resolution of the name of the server name (and not to the IP address on the form). The query must be authoritative and contain the name of the queried server. A type A query requesting the name of the name server is then sent to any name server that is able to perform recursive resolutions. The response must contain the name server’s IP address as given on the form. In addition, the name of the name server must be a canonical name and not an alias (CNAME). All the queries referred to above are sent as UDP datagrams and are resent three times at four-second intervals before a server is considered to be uncontactable.

Nous avons d'autres clients qui utilisent les serveur O2switch sans aucun souci.

Bonne journée

Isabelle
