Mon dédié ne peut joindre aucun autre serveur (ping ne répond pas)

C'est précisément ce qui s'est produit. Mauvaise configuration de l'IP FailOver, OVH a bloqué cette IP et comme elle était présente dans la liste des IP pour le bind, la résolution, DNS ne marchait plus du tout, serveur dédié coupé du reste du monde. C'est violent quand même

..... Mes IP FailOver semblent maintenant correctement configurées et je n'ai plus des erreurs arp à tout va.
Sache que ce genre d'erreurs ARP peut conduire OVH à bloquer l'IP.
Apparemment ils n'aiment pas ça.

.Ouf, quelle journée, mais j'ai appris pleins de choses ;-)
T'es sur la bonne voie !
T'as eu l'idée de consulter et montrer les logs. Ce qu'il faut faire. Il y a toujours quelqu'un qui reconnait de suite le "pas normal ça" avec comme résultat: t'as la solution

Oui, l'erreur à la base vient d'une mauvaise configuration de l'Ip FailOver.
Je suis sur CentOS, et je viens de comprendre que tout se passe via les scripts qui sont sous /etc/sysconfig/network-scripts (un script ifcfg-eth* par interface).
j'ai remis des fichiers corrigés, un coup de /etc/init.d/network restart et c'est bon partout. Mes IP FailOver semblent maintenant correctement configurées et je n'ai plus des erreurs arp à tout va.

Ce 178.32.46.zzz existe pour le serveur car il figure dans un fichier de config.
C'est un IP FO, donc c'est toi qui l'a mis en place, pas 'OVH'
Pour moi (Debian 7.6), c'est ici:
/etc/network/interfaces

C'est là ou j'ai les définitions comme:
post-up /sbin/ifconfig eth0:0 46.105.79.aa netmask 255.255.255.255 broadcast 46.105.79.aa
post-up /sbin/ifconfig eth0:1 5.196.43.bb netmask 255.255.255.255 broadcast 5.196.43.bb
post-up /sbin/ifconfig eth0:2 5.196.43.cc netmask 255.255.255.255 broadcast 5.196.43.cc

Attention pour l'application des tes edits:
/etc/init.d/network restart
ou
/etc/init.d/network stop ; /etc/init.d/network stop
sur un seul ligne (car sinon ......)

J'ai trouvé comment dit à bind de ne pas aller voir toutes les adresses IP.
Dans /etc/named.conf
remplacer
listen-on port 53 { ANY; };
par
listen-on port 53 { VOTRE_ADRESSE_IP; };

Un problème de résolu... Tout remarche correctement.
Reste à remettre une config correcte sur l'IP FO.

Merci pour ton aide Nowwat, c'était sympa

Exact, je viens juste de terminer la manip. Connexion en mode rescue, montage de la partition /, chroot et ifup de eth0.
Donc tout est revenu normal, sauf que j'ai toujours ce problème d'écoute sur une IP FO que je n'utilise pas (et qui est désactivée par OVH).

Savez vous comment enlever l'IP FO 178.32.46.235 de la liste ?
Là je sèche...

Bof.
Il faut toujours un truc comme ça pour tester "le mode rescue".
Il est fait pour gérer ce genre de situations.

Merci, je pense que c'est ça.
J'avais configuré un IP FO il y a quelques jours et je m'étais trompé dans le nom de l'interface. J'avais mis eth0 au lieu de eth0:1.
Et là je viens de faire une grosse connerie, j'ai fait un ifdown de ce fichier vérolé (donc ifdown de eth0) et visiblement je n'ai plus de réseau du tout. Le serveur ne répond plus...
Flute...
Une solution ?

Bonsoir,
Depuis ce matin je rencontre de gros soucis avec mon serveur dédié. Plus aucune connexion à des sites distants n'est possible. Je ne peux plus envoyer de mails.
Cela ressemble à un problème de DNS. Je n'ai fait aucune modification de la config.
Code:
[root@ns386328 ~]# ping www.google.com
ping: unknown host www.google.com
