Voici en images ce que je veux dire :

Pourquoi donc ip voit-il toujours eth0?
Ensuite, j'initialise wlan0 :
gizmotronics:~# ifup wlan0
gizmotronics:~# ip addr

Encore une fois, ifconfig me dit que tout va bien, et ip voit un problème.
À ce moment, j'ai un bon accès à 192.168.0.0/24, mais je ne peux pas
pinguer l'extérieur.
Je retire son IP à eth0 :
gizmotronics:~# ip addr del 192.168.0.2 dev eth0
gizmotronics:~# ip addr
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue

j'essaye de monter un répertoire en nfs :
gizmotronics:~# mount /moulinette/log/
là ça bloque :(
