Lors de la construction d'un bâtiment ou d'une maison il existe de nombreuses solutions « passives », c'est-à-dire ne nécessitant pas d'une intervention pour avoir une meilleure efficacité énergétique. Ça passe par une bonne orientation, le dimensionnement et le placement des ouvertures, faire en sorte d'éviter la surchauffe en été par la création d'ombre, isolation par l'extérieur pour éviter les ponts de chaleur, permettre une bonne circulation naturelle de l'air, etc. Comme dans bien des domaines, l'efficacité énergétique se recherche en jouant sur plusieurs facteurs.

En admettant que je trouve quelques choses sur la carte atheros comment faire pour installer le firmware sans internet sous debian???

Renseigne toi sur chroot qui te permettra d'installer des paquets sur ta Debian depuis Ubuntu.

Il me semble avoir compris que le VDSL est à la fibre ce que le NAT est au problème de l'IPv4. C'est pratique sur le coup mais ça ne fait que retarder l'échéance et au final ça fait payer deux fois.

La loi va se faire toute seule à partir du moment où le matériel incompatible IPv6 ne se vendra plus, les fournisseurs devront s'adapter ou perdre des ventes.

Tu auras le droit à quelques contenus pour te faire quelques idées.

Un redémarrage plus loin, mettre la carte en mode promicuous est la solution. Reste maintenant à remonter le problème mais je ne sais pas bien où.

Pour le noyau, j'ai le 3.5.4 et après ip set link eth0 promisc on ça semble tenir.

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.

À la fin de la vidéo, il est indiqué que le bonhomme a mis 600 heures pour faire son montage, il y a donc un coût qui n'est pas négligeable.

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.

Sur une autre machine on peut récupérer ceci :

rdisc6 --single wlan0

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.

Le dossioer sysctl.d est vide et voici le contenu de sysctl.conf

Ensuite j'ai testé rdisc6 --single eth0 avant et après avoir modifié la règle sysctl qui donne cette réponse dans les deux cas :

Solicitation de ff02::2 (ff02::2) sur eth0...

Pas de réponse.

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

Finalement les petites boites sont mises sous pression pour cause de pénurie d'IpV4. Les grosses boites qui ont encore de la marge ne font rien et les RIR exhortent le soleil a resurgir de derrière l'horizon.

À ce sujet, le point de vue de Benjamin Bayart est intéressant. Dans un billet de blog de fdn où il explique que les règles édictées pour IPv4 ont été bêtement transposées à IPv6 ce qui mène à des absurdités, je cite :

il est assez facile d'obtenir des adresses IP v4, mais pratiquement impossible d'obtenir des adresses IP v6 auprès du RIPE NCC.
[…]
Mais la belle règle prévue pour v4 est appliquée pour v6. Donc, dans un bloc PI en v6, il est interdit de distribuer des sous-réseaux. Or pour raccorder un abonné en IP v6, il est fortement préconisé de lui attribuer tout un réseau.

Ergo, il est interdit de raccorder des abonnés en IPv6 avec des blocs PI.

Il faut pertinenter dans le suivi pas ici

Pour les processeurs, je doute qu'ils voyent beaucoup de main d'œuvre dans les salles blanches.

Il est bien plus facile d'apprendre à taper à l'aveugle en BÉPO qu'en AZERTY puisque qu'il y a moins de déplacement des doigts lors de la frappe. Je dirais que le jeu en vaut la chandelle bien que le début soit pénible.

Une entrée dans le suivi avec, si possible, un patch.
