Connection Ethernet Impossible

Dernière réponse : dans Systèmes d'exploitation

Bonjour à tous,

Je suis sous Hardy, jusqu'a present sur toutes mes machines mon ethernet marchait y compris sous Hardy, depuis peu j'ai acheter un hp Pavilion a6460 et impossible de me connecter...

Je suis chez ClubInternet (clubinternetbox).

J'ai essayer de me connecter via le CD live mais il se produit la meme chose:

Apparement je me connecte au reseau local (un seul bouton vert allumé dans l'applet de mon tableau de bord), mais le deuxieme bouton vert ne s'allume pas donc impossible me connecter.

Help me !

C'est juste une commande qui permet à ton modem de t'attribuer une IP, et de t e reconnaître.

Je connais pas l'équivalent en graphique, mais ça doit exister.
Pour le lancer au démarrage, fais sudo gedit /etc/rc.local et avant la ligne exit tu ajoutes dhclient

Voilà, si quelqu'un connaît la démarche graphique qu'il se manifeste. :D 

dhclient est normalement lancé par networkmanager
quitte à le lancer manuellement, au lieu d'utiliser /etc/rc.local, vaut mieux utiliser /etc/network/interfaces ou l'outil graphique network-admin
mais ca suppose que tu dois désactiver networkmnager

pour ce qui est du fait que ca ne marche pas, il faudrait voir les logs pour avoir une piste

j'ai deux machines et en effet sa marches lorsque la deuxieme est etteinte (a moins d'un coup du hasard).

Que faire dans ce cas ? Car la deuxieme machine n'est pas toujours utilisé par moi et se que je ne comprend pas c'est qu'avant j'avais egalement deux machines avec exactement la meme connection et sa marchait nikel.

elle est comment ton installation? tu as quel modèle de modem/routeur?
tu as réinitialisé le modem/routeur de ci dernièrement?
il se peut que ce dernier soit en mode bridge, donc une seul connection possible, pour vérifier, lance un ifconfig sur la machine qui marche et note l'ip, si ce n'est pas un truc genre 192.168.x.x, 172.16.x.x ou 10.x.x.x, c'est que c'est le cas, il faudra le configurer

Ce que je ne comprend pas c'est que lorque je suis sous Windows les deux PC peuvent etre connecter il n'y a pas de souci, mais des que je suis sous Ubuntu sa ne marches plus.

De plus ce matin, je n'es pas pu me connecter sous Ubuntu alors que le second PC était éteind.

au fait, c'est par wifi ou par cable?
sous windows, c'est un installation par cd ou sans cd?
tu peux voir dans /var/log/messages s'il n'y a pas d'erreurs spécifiques au réseau?
ton modem/routeur, il a combien de ports? tu as la télé avec?

Mon PC principal (celui sur lequel j'ai des souci en ce moment) est connecter via ethernet, et je n'ai pas installer le cd pour la club-internet-box.
Il marches tres bien sous Windows mais pas sur Ubuntu.

Mon second PC (laptop) est connecter via WIFI est est sur Ubuntu.

Sinon je n'es pas la tele avec.

Voici les derniere ligne de /var/log/messages/
