Problème d'interface internet - ou plutôt : Problème d'interface réseau
Re-bonsoir à tous et à toutes,
bonsoir à Grégory,
Cette fois, c'est sur tes demandes de manips que je reviens.

pour moi, gl620a ou d'une façon plus générale usb0 fiche le souc après
son activation.
dans /etc/modprobe.d/blacklist tu ajoute ton gl620a pour éviter le
chargement au boot suivant, cf mon post Wed, 9 Sep 2009 16:47:25 +0200
Fait !
dans on knetwork manager vérifie que le résau avec la carte e100 soit
bien le réseau filaire par défaut
Fait !
tu ouvre 2 consoles :
- la 1er : tail -f /var/log/syslog , tu appuis plusieurs fois sur entree
pour aérer les anciens logs qui ne nous interressent pas
- la 2ième :
ifconfig down gl620a
modprobe -r gl620a
/etc/init.d/[k]network* restart
un ifconfig pour être sur que usb0 n'existe pas.
d'ailleurs la question que je me pose : comment-il possible
que /etc/udev/rules.d/70-persistent-net.rules n'indique rien pour la
mac address usb, usb0 soit quand même affecté à une interface réseau ?
- c'est avahi qui fait ça (donc par extension Network-Manager)
- c'est un truc dans /etc/network/[pre]if-up qui ficherais le souc
(comment il serait arrivé là ?)
Et voici les résultats des deux consoles...

Je m'en vais de ce pas faire un reboot et vous tiens aussitôt après au
courant...
Encore deux questions - vu que le débutant que je suis a tout de même
fouillé en pas mal d'endroits...
1) Pourrait-on blacklister le module usbnet plutôt que gl620a ?
(disons... parce qu'il semble être au-dessus de [= de niveau supérieur]
gl620a)
2) Pouvait-on aussi agir sur /etc/resolvconf/interface-order qui
contient l'ordre des interfaces : en décommentant la dernière ligne
« * » pour que « toute autre interface » ne soit pas considérée ?
Bon, alors à tout de suite après le reboot !
Cordialement
Ludovic
