Merci - malgré que ce n'ait pas été résolu - comment fait on car je n'ai pas de problème maintenant ?

Ceci étant, il me semble que ce sont des paquets d'installation suite à mise à jour qui sont à l'origine du plantage... car j'étais en mise à jour de 12.04 à 12.10 et Rtu_samba qui était à la base de mon partage précédent n'a pas migré ! J'aimais assez ce module qui permettait des partages simples et rapide... bon là - on ne se plaint pas, ça fonctionne, mais parfois c'est long... en tout cas ... MERCI à LA COMMUNAUTE...

edit : ou pour les newbies passer par Applications > outils systeme > administration > samba

Merci

attention a bien adapter mon smb.conf a ton cas (c'est au niveau des partages qu'il faut modifier)

Heureux de ta réponse ! je n'avais pas sous estimé le caractère "impossible" - qu'appelles tu "faire le ménage" ... j'ai supprimé avec synaptic les paquets samba et réinstaller, y a t il une autre méthode en mode "terminal" dont je n'ai pas l'usage puisque novice...
je tente ton sbm.conf et si ça fonctionne pas ! je repasse en 10.10 ! j'en ai ras le bol !
Et comme je le disais quand j'avais 20 ans : on arrête pas le progrès...c'est le progrès qui nous arrête !

la section [global] c'est du n'importe quoi, il y a plein de directives qui sont inutiles...et des erreurs flagrantes comme les adresse définis en 192.168.0/24 alors que ton réseau est en 192.168.1/24 !! Soit tu change pour adapter a ta config, soit tu comment ces lignes.

Pour la section Global (et le reste), voila un exemple de fichier smb.conf fonctionnel (attention quand meme les partages définit dans ce fichier cdrom, jim-Public et jim-Partage sont donnés a titre d'exemple, a toi d'adapter a ton cas, le nom du workgroup aussi :-)

je te poste ceux du serveur après

J'ai allumé mon eeepc 701 sur lubuntu 12.04 ! il ne me donne pas accès au serveur (liste de partage échoué) mais me fait voir le réseau toutefois et me donne accès à la box... donc j'ai bien un soucis sur le serveur aussi...

si tu pense a un probleme réseau ou de modules essaye de tester ton réseau a coup de ping (de A vers B, de B vers A, de A et B vers routeur) si cela ne marche pas faudra creuser de se coté la.
Enfin, la box elle jouent quand meme le role de "lien" entre tous tes pcs, elle est elle aussi impacté selon tes configurations, donc meme si on ne touche pas a sa configuration, un petit reboot pour etre sur qu'elle voient les changements sur ton réseau ne peut pas lui faire de mal...

Le problème est que je ne vois ni ma box, ni mon serveur et je veux bien comprendre que le serveur peut avoir des ratés... mais en aucun cas la box ! voilà pourquoi je pense que c'est le module du wifi qui coupait précédemment jusqu'à ce que je désinstalle amazon et que je doive relancer le wifi à la main avec une commande dont je ne me rappelle plus et je pense, en ne connaissant pas grand chose, que le module ATH9K doit m’empêcher l’accès au réseau sans pour autant m’empêcher d'atteindre internet ! bizarre...
