Répertoires privés et public samba. [RESOLU]

Répertoires privés et public samba. [RESOLU] - réseaux et sécurité - Linux et OS Alternatifs

Marsh Posté le 10-06-2007 à 21:52:49    

Bonjour,
 
Je veux faire un serveur de fichiers avec samba. Alors j'ai passé mon après midi a essayer de configuré samba dans tout les sens mais je n'arrive pas à se que je veux alors je vous expose mon souhait.
J'ai deux répertoires :  
-Public --> acessible par tous et par dupond sans aucun mot de passe ni histoire d'utilisateur
-Dupond --> acessible que par dupond et aucune lecteure par personne d'autre
 
Alors dans smb.conf si je met dans :
 
1) [GLOBAL] : security = user
Dupond a bien accès aux deux répertoires mais un invité a une demande de login.
 
2) [GLOBAL] : security = share
Dupond et on accès à public sans login mais demande de login pour Dupond pour aller dans le répertoire Dupond.
Je précise que dans [DUPOND] j'ai bien autorisé l'utilisateur, enfin je pense.
 
3) [GLOBAL] : security = user
authentication : security = share
Idem que le 2).
 
4) [GLOBAL] : security = share
authentication : security = user
Idem que le 1)
 
Donc en fait les deux marche mais jamais ensemble.
 
Je me demande si se que je demande c'est possible de faire. Je vous met mon smb.conf pour voir si j'ai fait des erreurs ailleurs.
Merci, je sais, faut être motivé pour répondre à mon problème mais la j'ai déjà essayer plein de choses mais je n'a pas rencontrer quelqu'un qui veut faire comme moi après des recherches sur des forums sur internet.
 
smb.conf :

repasse dans ta config 1 et change un truc dans ton fichier de conf :
 
invalid users = root nobody
 
Sinon, pour info :
Read only et writable ont le même sens donc l'un ou l'autre suffit, pas besoin des deux

Merci de ta réponse, je l'est aplliqué et de diverses façon mais ça ne marche pas.
Mais je me rend compte que ce n'est pas possible en fait pour [PUBLIC] il faudrai un security = share et pour [Jean-Marie] un security = user mais les deux ensemble faudrait que l'on me dise si ça peut se faire.

essaye ca :


[global]
...
security=user
invalid users = root
guest account = nobody
map to guest = bad user
...

 

[public]
comment = "public"
path = /home/partages/public
Guest ok = yes
browseable = yes
 
[jean-marie]
comment = "jean-marie"
path = /home/partages/jean-marie
Guest ok = no
browseable = yes
Valid Users = jean-marie
write list = jean-marie
writable = yes
 

 

je te dis ca de tete
c'est la directive map to guest qui fait la difference
jeanmarie est connu du systeme donc il aura acces aux deux partages public et jean-marie
mais un user quelconque inconnu du systeme, sera redirigé vers guest (map to guest) et aura donc acces a public

 

en fait ca donne ca:
map to guest a plusieurs valeurs:
man smb.conf
bad user : utilisateur inconnu est remapé vers guest account
mais un user connu avec un mauvais password n'est pas remappé
bad password: seuls des users connus mais avec mauvais password seront remappés

merci à vous, ça marche !!! je connaissais pas map to guest, enfin normal sa fait pas très longtemp que j'utilise linux. SAUF que maintenant je n'ai aucun pouvoir sur le répertoire public avec un compte anonyme et même jean-marie, je ne peux pas creer de dossier par exemple mais je rentre bien dans le dossier. Mon dossier public a bien chmod 0777 et j'ai même rajouté : create mode = 0777
directory mode = 0777
mais rien n'y fait.
