Tu penses donc que les adresses que j'ai laissées dans la trace ci-dessus ne sont pas chez toi ?
De plus en plus fort, tu verrais donc les broadcasts de LAN d'autres clients K-Net ?

Superpicsou · « **Réponse #86 le:** 13 avril 2022 à 11:26:37 »

Aucune idée, encore une fois je n'ai pas les compétences techniques pour analyser ces flux.

Juste je comprend pas pourquoi ces requête sur des ip local qui n'existe pas chez moi. J'imagine que ya un lien avec le fait que mon réseau local pète les plombs, toutes ces déconnexion et le fait que j'ai du mal à accéder à la config de ma box. Mais encore une fois, simple supposition, aucune idée.

Il n'y a pas de moyen de limiter ces problèmes sur Mac le temps que ca soit corrigé coté KNET ?

On est d'accord que KNET est au courant de ces problèmes sur nos box ?

J'espère qu'ils sont au courant.
Perso, avec mon propre routeur Asus j'ai aussi des soucis de résolution DNS depuis samedi vers 14h.
2 appels à knet, réponse laconique.. j'informe nos ingénieurs...

Rappel sav téléphonique.

En gros ils avaient ouvert un ticket chez covage pour "perte de service" (donc plus d'internet, ce qui n'était pas mon cas). Avec la résolutions du soucis hier, Covage à clôturé tout les tickets pour ce problème.

Du coup, K-net refait un ticket à Covage pour "dégradation de service" et non plus perte. Et c'est tout.
Donc pour eux, toujours rien à voir avec l'icotera. C'est du côté de Covage.

Wait & See et patiente.

S'ils t'ont donné un numéro de ticket en [K-NET#20220413xxxxxxx], envoie leur quand même les traces que tu obtiens par tcpdump en mettant ce numéro de ticket en sujet.

Il y a toujours eu des paquets APIPA et en 192.168… qui traînent dans le GPON…

J'en avais détecté pas mal il y a quelques années, venant d'appareils divers et variés (deux Synology, des IOT genre thermostats, et autres interfaces et même une Freebox…)
Je pensais à l'époque que ça venait de quelqu'un qui avait mis son switch au mauvais endroit, mais c'était peut-être quelqu'un victime de de bogue Icotera…
À l'époque, VincentO2 qui était encore chez K-Net s'était penché sur la question, et la plus grosse difficulté pour K-Net était qu'ils n'ont pas accès au GPON, car ce qu'il s'y passe est filtré avant que ça leur parvienne et ils ne peuvent pas voir tous ces paquets ; je lui avais envoyé une base de donnée avec toutes les adresses MAC de ces appareils, et il a fait ce qu'il a pu, je crois en vain, ça n'avait jamais pu être résolu…

Il y avait tout un sujet dédié que j'avais ouvert sur le forum Caps…

Au final, entre les personnes qui établissent leur réseau incorrectement, ceux qui ont activé par mégarde ou négligence un port mirroring, ceux qui ont du matériel perso et ne savent pas l'utiliser, il y a toujours des fuites de certains LAN sur le GPON.

Mon routeur filtre déjà ces paquets, mais comme ils sont broadcast/multicast, ils forçaient mon routeur à utiliser plus de ressources que nécessaire.
Comme je suis puriste et que j'aime optimiser, j'ai établi des règles ebtables et iptables sur mon routeur pour filtrer tout cela au plus tôt :

Code: [Sélectionner]

root@HERMES:~$ ebtables -L
Bridge table: filter

Bridge chain: INPUT, entries: 1, policy: ACCEPT
-i ethwan -j auth_macs

Bridge chain: FORWARD, entries: 1, policy: ACCEPT
-i ethwan -j auth_macs

Bridge chain: OUTPUT, entries: 0, policy: ACCEPT

Bridge chain: auth_macs, entries: 2, policy: ACCEPT
-s 20:e0:9c:53:7a:9 -j RETURN 
-j DROP

20:e0:9c:53:7a:9, c'est la MAC de ma passerelle Covage.
Cela signifie que tout ce qui provient depuis le WAN d'un appareil avec une MAC différente de la passerelle Covage sur laquelle je suis relié est rejeté à l'entrée du routeur.

De plus, j'ai aussi cette règle iptables (et son équivalent en ip6tables que je ne mets pas ici pour ne pas surcharger) :

Code: [Sélectionner]

-P PREROUTING ACCEPT
-A PREROUTING -i brwan -m set ! --match-set brwan_in_auth dst -j DROP

Avec

Code: [Sélectionner]

root@HERMES:~$ ipset -L brwan_in_auth
Name: brwan_in_auth
Type: hash:ip
Revision: 5
Header: family inet hashsize 1024 maxelem 65536 bucketsize 12 initval 0xb7ec9594
Size in memory: 240
References: 1
Number of entries: 3
Members:
[MON IP]
255.255.255.255
[LE BROADCAST DE MON SOUS-RÉSEAU]

Cette combinaison iptables et ipset s'assure que tout paquet qui arrive du WAN qui n'est pas un broadcast global, un broadcast de mon sous-réseau ou destiné à mon adresse IP est automatiquement rejeté au plus tôt (la table raw étant la première, j'évite que les paquets indésirables polluent les règles suivantes dans les tables mangle, filter, etc…).

J'ai un peu simplifié mes règles ici à celle qui sont pertinentes… Elles sont un peu plus complexes, car j'accède à mon ONT pour du monitoring par exemple…

Et bien ça filtre en masse…
Voici par exemple le tcpdump depuis le routeur qui montre sur 2 secondes tout ce qui ne vient pas en broadcast ou multicast de ma passerelle Covage (donc qui est stoppé par ma règle ebtables) :

Code: [Sélectionner]

root@HERMES:~$ tcpdump -i ethwan -ne ether broadcast or ether multicast | grep -ve 20:e0:9c:53:7a:9

^C68 packets captured
72 packets received by filter

La plupart de ces paquets sont normaux (en particulier les paquets DHCP (v4 ou v6) [du moment qu'ils ne sont pas spammés 4 000 fois par seconde

]) et auraient été bloqués plus loin par mon routeur qui ne les auraient pas routé vers mon LAN.
On voit des paquets anormaux comme 192.168.1.56 venant de la fuite WAN/LAN chez quelqu'un ou une mauvaise configuration de leur réseau ou paramètres, qui eux aussi auraient été bloqués plus loin par mon routeur. Ce sont d'ailleurs les mêmes paquets que Superpicsou voit arriver dans son LAN, puisqu'on est sur le même GPON.

Avec ces règles spécifiques, je bloque ces paquets le plus tôt possible

Rappel sav téléphonique.

En gros ils avaient ouvert un ticket chez covage pour "perte de service" (donc plus d'internet, ce qui n'était pas mon cas). Avec la résolutions du soucis hier, Covage à clôturé tout les tickets pour ce problème.

Du coup, K-net refait un ticket à Covage pour "dégradation de service" et non plus perte. Et c'est tout.
Donc pour eux, toujours rien à voir avec l'icotera. C'est du côté de Covage.

Wait & See et patiente.

¯\_(ツ)_/¯

Ils semblent renvoyer la faute à Covage…
Je vois mal comment Covage peut être responsable de ton Icotera qui a un problème (matériel, logiciel ou mauvaise configs envoyées)

Cela semble être le cas, mais avez-vous vérifié que votre problème est le même que Superpicsou ?
Avez-vous pu effectuer la commande tcpdump -ne ether broadcast or ether multicast | grep -ve 192.168.1
Et constater la fuite de paquets WAN dans votre LAN ?

Haha j'allais venir dire la même chose. L'horreur. La connexion ne tiens pas. En tout cas le mac perd la connexion. Impossible de ping l'icotera en local
