Je suis chez Free avec l'IPv6 activé et je n'arrive pas à avoir une adresse IPv6. Je suis sous Archlinux avec une distribution à jour.
Au niveau matériel j'ai ceci :

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 09)
        Subsystem: ASUSTeK Computer Inc. Device 8505
        Flags: bus master, fast devsel, latency 0, IRQ 44
        I/O ports at e000 [size=256]
        Memory at f0004000 (64-bit, prefetchable) [size=4K]
        Memory at f0000000 (64-bit, prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: r8169

Si je fais dhcpcd -d eth0 ça me raconte ceci :

Qu'est-ce que vous me suggérez de faire ?

  • # Pas de DHCP

    DHCP c'est une technique spécifique à IPv4 (enfin, il existe aussi un DHCP IPv6 mais je ne sais pas si c'est utilisé et il faut un serveur DHCP6), pour IPv6, il y a l'autoconfiguration qui permet d'avoir une adresse sans serveur DHCP. Pour activer cette dernière, il me semble que c'est assez spécifique à la distribution.

      Normalement, l'auto-configuration IPv6 est bien activée par défaut sur Archlinux.
      Par contre : aurais-tu des règles Netfilter de déclarées sur ta machine ? Si oui, ne filtrerais-tu pas les paquets ICMP entrant ?

        Je n'ai édité aucune règle c'est donc celles par défaut qui sont appliquées. Je vais regarder cette histoire de paquets ICMP.

                  Pour moi net.ipv6.conf.eth0.accept_ra = 0 devrait être à 1.

                  Sinon tu peux utiliser rdisc6 pour faire des requêtes "Router Discovery" et voir les réponses.

                    En effet, c'est sans doute la cause du problème.
                    Tu peux nous donner le contenu de ton fichier /etc/sysctl.conf (et, s'il y en a, le contenu des fichiers du répertoire /etc/sysctl.d) ?

                    Pour tester le fonctionnement du RA sans toucher au fichier sysctl.conf, tape la commande suivante :
                    # sysctl -w net.ipv6.conf.eth0.accept_ra = 1

                        Tu es sur que ton routeur gère correctement le V6 ? la majorité des boites noir chinoises ne le font pas.

                        Si tu lances Wireshark sur ta carte ethernet, tu dois avoir des trames de type "router avertisement" toutes les X secondes.

    sur ubuntu le noyau est ipv6 par defaut, mais on peut le desactiver au boot en lui disant ipv6.disable=1 sur la ligne de grub

    ta distrib fait peut-etre l'inverse, elle desactive pour l'instant l'ipv6 par defaut ?

      Je ne pense pas. Son interface eth0 possède une adresse de lien local.

      J'ai plus le sentiment que c'est la carte réseau qui est casse-bonbon puisque j'ai une autre machine qui est se connecte parfaitement en IPv6 sans poser le moindre soucis.

        Je me suis rendu compte que IPv6 était installé sur mon serveur et que c'était un peu opération porte ouverte puisque je n'avais pas réfléchit à la question.

        Un petit ping6 www.google.com permet de voir si IPv6 "marche" pour un débutant comme moi.

        Ensuite on peut faire des tests comme ssh -6 et autres pour les différents logiciels. De ce que j'ai pu constater, il est souvent difficile de savoir par quoi on passe sauf à spécifier une adresse IPv6 ou une option particulière qui n'existe pas toujours.

        Autrement, pour iptables ca marche pareil (ip6tables) sauf pour le ping :
        ip6tables -t filter -A INPUT -p ipv6-icmp -j ACCEPT

            J'ai fait en sorte d'avoir les mêmes réglages sans effets apparents. Puis en regardant les trames réseaux avec tcpdump ça a décider à tomber en marche.
            Je verrai au prochain démarrage de conserver ou non tes réglages.

    J'arrive à avoir une connectivité IPv6 mais elle n'est pas stable.
    Je fais des capture réseaux avec tcpdump -nvvv ip6 et ça marche, j'ai une réponse sur ping6 google.fr. Je stoppe les captures réseaux, quelques minutes plus tard ça ne marche plus, ping6 google.fr me dis que tous les paquets sont perdus.

      Si mettre la carte en mode promiscuous résoud ton problème, c'est plus un bug de ta carte réseau/driver qu'autre chose.

      Essaye de lancer tcpdump avec l'option -p (sans promiscuous) et regarde si ça continue à ne pas marcher. Puis stoppe la capture et lance ip link set eth0 promisc. Si ça se met à marcher, alors c'est très certainement un bug du driver de ta carte réseau.

      Dans ce cas la, les diagnostics noyau habituels s'appliquent: Donne nous la version de ton noyau, et essaye un noyau plus récent si possible.
