Bonjour à toutes et tous
De façon à avoir un sous-domaine pour pointer sur mon serveur Nextcloud, j'ai créé un sous-domaine via mon fournisseur de domaine, Infomaniak, que j'utilise comme DNS dynamique.
Pour lier donc dynamiquement (au cas où l'IP changerait) mon serveur et mon sous-domaine, j'utilise le service DDClient.
J'ai installé le paquet DDClient via YaST et j'ai mis à jour le fichier de configuration /etc/ddclient.conf
Il se présente ainsi :

En fait, j'ai ajouté les informations liées à mon prestataire Infomaniak en fin de fichier.
J'ai ensuite lancé le service par
sudo systemctl enable --now ddclient
Pour vérifier que tout se passe bien je lance la commande sudo ddclient -query
et j'obtiens alors quelque chose que je trouve bizarre :
use=if, if=eth0 address is 192.168.1.20
use=if, if=lo address is 127.0.0.1
WARNING: found neither ipv4 nor ipv6 address
use=if, if=wlan1 address is NOT FOUND
WARNING: found neither ipv4 nor ipv6 address
use=web, web=dnspark address is NOT FOUND
use=web, web=dyndns address is xx.xxx.xx.xx
use=web, web=loopia address is xx.xxx.xx.xx
use=web, web=https://ipv4.infomaniak.com/ip.php address is xx.xxx.xx.xx
Le xx.xxx.xx.xx est mon adresse IP que je masque ici.
Ce que je trouve bizare, c'est que DDClient semble faire une requête non seulement à Infomaniak que j'ai ajouté mais aussi à dnspark, dyndns et loopia qui sont pourtant commentés dans le fichier /etc/ddclient.conf et donc pas à prendre en compte.
Du coup, je me pose la question s'il y a une autre fichier de configuration de DDClient qui demande d'interroger des prestataires que je n'ai pas choisi ?
Merci pour vos lumières !
