ADSL OVH, trafic non désiré

Message par **dsebire** » lun. 23 mars 2015 13:07

Bonjour,

posté sur le forum OVH, mais j'aimerais un avis des furieux d'ici:

Comme indiqué dans le sujet, j'ai souscrit pour mon entreprise a une ADSL pro OVH (dégroupée, avec GTR)

la ligne a 1 an, et fonctionne plutôt bien (débit pas super top, mais assez loin du central)

le modem est configuré en bridge.

aujourd'hui, la ligne n'est pas utilisée (lien backup) , ce qui n'était pas le cas avant.
bizarrement, je vois toujours les LEDs clignoter sur le modem et le routeur.

j'ai donc effectué un dump de ce qui passe, et j'ai eu la (désagréable) surprise de constater que du trafic arrive sur mon router qui ne m'est absolument pas destiné.

mon adresse est du style 109.190.186.XX, et je vois de nombreuses trames destinées à d'autres IP dans la tranche 109.190.178.ZZZ
l'exemple le plus flagrant est celui du monitoring OVH, ou je reçois toutes les 5 secondes une vingtaines de trames ICMP, dont une seule est destinée a mon IP.

en résume, j'ai l'impression que le broadcast n'est pas filtré ou que le routage est foireux et que du coup de la bande passante est consommée pour rien par des trames destinées aux voisins.

sur 10sec, voici ce qui passe (et qui n'a rien à voir avec moi):

j'ai raison de m’inquiéter ???

ma ligne est pas super bonne, et ça pompe quand même pas mal de BP en proportion.

Merci

je dirais que oui, après clairement soit y a un soucis de leur coté soit ils ont une manière particulière de monitorer les lignes oO

Message par **dsebire** » lun. 23 mars 2015 13:40

ya pas que le monitoring OVH.
dans mon exemple, ya quasi que ça c'est vrai mais regarde le paquet 94 par ex

ya aussi des IP qui n'ont rien a voir avec OVH qui arrivent chez moi en tentant de joindre une autre IP que la mienne.

je dirais réseau ovh :/ il est pas super clean.

t'as bien de la perte de paquets et de la chute de débit, suivant le modèle de serveur que tu as et sa baie de host.

moche mais pas super étonnant je dirais. A remonter au support, je suis curieux de savoir si tu peux y faire quelque chose

Message par **dsebire** » lun. 23 mars 2015 13:54

j'ai pas de perte de paquets, mais de la BP consommée en permanence alors que ya rien qui passe sur le lien (pour moi je veux dire)

pour info, une fois viré tout ce qui est OVH, il me reste ça (dump 1mn ce matin):

sur une capture d'une minute a l'instant, il reste 1 paquet qui n'a rien a voir avec la choucroute (dst 109.190.187.215)
et il y a toujours ces trames HSRP, dont je doute de l'utilité sur une ligne xDSL (surtout quand le modem derrière est en bridge)

Merci !

réponse OVH:

Bonjour,

Je vous remercie pour votre retour.

Les trames HSPR correspondent aux communications entre les deux routeurs 252 et 253 qui gèrent le BackUp. Nous ne pourrons donc éviter ce types de trames d'apparaitre.

Souvent tu configures des tests de vie VRRP sur plusieurs liens pour la résilience.
Il y a peut-être un lien 1:1 pour tests de vie, synchro de config, HA et tout
PLUS tests de vie sur un second lien. Mais ça devrait être leur lien côté backbone opérateur. Rien à faire côté ligne client selon moi. D'autant que ça ne risque pas d'atteindre le peer par ce lien....

Juste un petit message car OVH m'énerve (rien à voir avec l'ADSL).
Je modifie les GLUE d'un domaine car j'avais 4 DNS, le 3eme dégage et le 4eme devient le 3eme.

J'ai beau modifier, quand je reconfigure le 3ème, une requête DNS répond sans cesse l'ANCIENNE adresse IP et pas la nouvelle, alors que l'interface affiche la nouvelle IP.

Et si je vire le 3ème des GLUE, il répond que pour le 1 et 2, et quand je remets le 3ème, il remet toujours l'ancienne IP -_-

Message par **dsebire** » lun. 13 avr. 2015 14:03

c'est quoi le TTL ?

Message par **Zedoune** » lun. 13 avr. 2015 14:06

t'as un souci de propagation.
c'est quoi le TTL ?

si je mets pas de ns3, le site dnscheck.pingdom.com me dit que tout est OK, et si je mets le ns3, il me dit erreur parce que OVH renvoie bien l'ancienne IP du ns3.
Si c'était un problème de cache, ce serait toujours faux ? Là où voit bien le retrait de NS3 (je peux faire un dig aussi ça marche très bien). Le TTL du GLUE c'est pas moi qui le gère ça de toute façon ?

j'ai déjà eu des soucis comme ça, trop de manips d'un coup et un peu dans tous les sens, c'est parti en vrille.
48h plus tard, sans rien modifier, c'est rentré dans l'ordre.

A ta place, je supprimerais ce qui marche pas (le 3 et 4 donc), tu attends 2-3 jours et tu remet celui qui manque.
