Partage + permission avec Samba

Bonjour,

Je vais faire un recap de l'usage de ma machine Ubuntu.Elle me sert comme serveur Plex pour mes films et séries. Je suis sous ubuntu 14.10.

J'utilise transmission en Remote pour mes torrents. Cela va très bien. J'ai également un partage Samba pour chacun de mes disque dur. 2 interne branché en Sata, et 1 externe branché en eSata. A partir de la machine local, aucun problème d'accès au fichier.

Par contre, j'utilise Samba pour partagé mes fichiers et répertoires sur le réseau, afin de les géré. Lorsque je veux prendre un fichier X(dans le répertoire download) et l'envoyer vers mon dossier Film, a partir d'un PC sous Windows, bien que j'ai accès en lecture a chacun des fichiers, je ne peu les déplacé nul part, ou modifier le nom, ou quoi que ce soit. Je doit impérativement le faire localement sur la machine.

Pour accédé a mes fichiers a partir du réseau, j'utilise un login invité(puisqu'il n'accepte pas mon login ubuntu). Si je change les permissions manuellement grace a l'interface graphique, ou un chmod sur mon répertoire, je peu le faire a partir de mon pc Windows a distance. Par contre, tous les fichiers subséquents que je rajoute, je dois refaire les permissions a chaque fois pour que cela fonctionne.

Quelqu'un a une solution a mon problème? J'ai déjà parcouru beaucoup de forum, tenté en vain plusieurs procédure trouvé(chmod, installation GUI samba, tenter de me rajouter au groupe samba, etc).

Merci!

Re : Partage + permission avec Samba

Bonsoir,
Si tous tes disques sont en ext4, tu dois pouvoir programmer Samba pour accéder en lecture et écriture aux fichiers et dossiers partagés.
Logiquement, racisme primaire je sais, on ne donne pas au groupe invité l'accès en écriture, il te faut donc on compte particulier protégé par mot de passe ... pas forcément le mot de passe local, ça se discute au niveau sécurité.

Re : Partage + permission avec Samba

Je comprend l'enjeu de sécurité. C'est ainsi car je me suis tanné du bidouillage.

Peut-être quelqu'un sait comment, si je n'active pas l'accès invité pour Samba, quand je rentre mon login a partir de mon pc Windows pour avoir accès au partage, il me refuse l'accès. J'ai porté bien attention de bien rentré mon login, mais c'est toujours refusé, quoi que je fasse.

Effectivement tout es en Ext4, incluant le disque externe. Comment je programme ce fameux Samba? Il ne semble pas avoir de GUI natif, et le logiciel que j'ai installé, me permet de mettre lecture/ecriture, mais malgré sa, sa ne fonctionne pas.

merci!

Re : Partage + permission avec Samba

Des « gui » je me méfie un peu, tout est ou devrait être dans /etc/smb.conf.
Tu en fais une copie de sauvegarde et étudies les divers paramètres. Attention je crois qu'il y a de légères modifications sur les dernières versions.
Pour vérifier la syntaxe tu as le programme testparm.

Re : Partage + permission avec Samba

Voici a ce que ressemble mon smb.conf(en passant, trouver dans etc/samba/smb.conf, il n'y en avais pas dans /etc

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.

#======================= Global Settings =======================

[global]

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of
    workgroup = WORKGROUP

# server string is the equivalent of the NT Description field
    server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
#   wins support = no

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
;   wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
    dns proxy = no

    usershare owner only = false

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes

#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects
    log file = /var/log/samba/log.%m

# Cap the size of the individual log files (in KiB).
    max log size = 1000

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.
    syslog = 0

# Do something sensible when Samba crashes: mail the admin a backtrace
    panic action = /usr/share/samba/panic-action %d

####### Authentication #######

# Server role. Defines in which mode Samba will operate. Possible
# values are "standalone server", "member server", "classic primary
# domain controller", "classic backup domain controller", "active
# directory domain controller".
#
# Most people will want "standalone sever" or "member server".
# Running as "active directory domain controller" will require first
# running "samba-tool domain provision" to wipe databases and create a
# new domain.
    server role = standalone server

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using. 
;    passdb backend = tdbsam

    obey pam restrictions = yes

# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
    unix password sync = yes

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).
    passwd program = /usr/bin/passwd %u
    passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.
    pam password change = yes

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
    map to guest = bad user

########## Domains ###########

# classic domain controller', 'server role = backup domain controller'

# It specifies the location of a user's home directory (from the client
# point of view)

# The following setting only takes effect if 'domain logons' is set
# It specifies the script to run during logon. The script must be stored
# in the [netlogon] share
# NOTE: Must be store in 'DOS' file format convention

# RPC pipe.  The example command creates a user account with a disabled Unix
# password; please adapt to your needs

Re : Partage + permission avec Samba

Au temps pour moi, j'avais zappé une étape de l'arborescence.
Ceci dit, va déjà voir par là, même si ça date un peu.
Ensuite je ne vois pas de paramètre « security », à moins que ce ne soit devenu inutile ...
Si j'ai bien compris, tu partages un seul répertoire /media/plx.
Avec un peu de chance un intervenant plus au courant des versions actuelles pourra t'aider, samba est un sujet assez couru ces temps ci.

Re : Partage + permission avec Samba

Je vais lire sa attentivement. Merci du lien.

Ce qui es curieux, c'est qu'il n'a pas que le plx qui es partagé, mais environ 6 repertoires différent... Mais c'Est le seul listé dans le samba conf...
