Problèmes Samba après changement serveur en 14.04

Bonjour à tous,
j'ai fait migrer un serveur Samba dans une association pour le passer en 14.04 et depuis je constate que:
- certains postes ne peuvent plus se connecter,
- à l'opposé, d'autres accèdent sans mot de passe à tous les partages, même en dehors des droits qui leur sont attribués.
Autres particularités:
- le serveur n'apparaît pas avec son nom hostname dans le réseau Windows Seven mais seulement avec son IP locale après connexion,
- la réponse de la commande smbtree ne prend pas en compte ni le groupe de travail (WORKSTATION au lieu du groupe configuré dans Samba), ni les partages du serveur,
- la réponse de smbstatus ne fait pas apparaître les postes connectés, ni les fichiers ouverts.
Sur un autre serveur autrepart, le passage en 14.04 s'est fait en douceur.
Quelqu'un aurait-il des axes de vérification à suggérer pour régler ces problèmes ?

Bonsoir, même problème pour moi, je suis preneur de solution. A savoir que j'ai conservé lors de la mise à jour le fichier de configuration précédent. Merci d'avance

Re : Problèmes Samba après changement serveur en 14.04

Bonjour,

je conseille à tout le monde de lire ce fabuleux how-to de ESR (http://www.catb.org/~esr/faqs/smart-questions.html)

peux-tu nous en donner davantage ?
Quels OS, Softwares accèdent à ton serveur Samba ?
Quelle est la version de ton serveur samba ? et l'ancienne ?
S'est-il passé quelque-chose de particulier lors de la mise à jour ?
As-tu regardé tes logs ?
As-tu un pare-feu actif ?
Peux-tu nous donner ta configuration samba actuelle ? et l'ancienne ?

Re : Problèmes Samba après changement serveur en 14.04

peux-tu nous en donner davantage ?
-> Mon serveur tourne sur Lubuntu 14.04 LTS en 64 bits

Quels OS, Softwares accèdent à ton serveur Samba ?
-> Linux (lubuntu), Windows (7), MacOSX

Quelle est la version de ton serveur samba ? et l'ancienne ?
-> La version de mon serveur samba est la dernière, cependant je ne sais pas comment connaitre sa version.

S'est-il passé quelque-chose de particulier lors de la mise à jour ?
-> Lors de la mise a jour l'utilitaire m'a proposé de garder le fichier de configuration précédent (ce que j'ai fais)

As-tu regardé tes logs ?
-> Oui, mais je n'y comprend rien. Je suis un débutant sur Linux.

As-tu un pare-feu actif ?
-> Oui,  normalement le port est ouvert à moins que la mise a jour l'ait fermé.

Peux-tu nous donner ta configuration samba actuelle ? et l'ancienne ?
-> Voici la configuration de mon serveur samba actuel qui correspond à l'ancienne puisque j'ai rien modifier depuis la mise à jour.

# By default, \\server\username shares can be connected to by anyone
# with access to the samba server. Un-comment the following parameter
# to make sure that only "username" can connect to \\server\username
# The following parameter makes sure that only "username" can connect
#
# This might need tweaking when using external authentication schemes
;   valid users = %S

# Un-comment the following and create the netlogon directory for Domain Logons
# (you need to configure Samba to act as a domain controller too.)
;[netlogon]
;   comment = Network Logon Service
;   path = /home/samba/netlogon
;   guest ok = yes
;   read only = yes

# Un-comment the following and create the profiles directory to store
# users profiles (see the "logon path" option above)
# (you need to configure Samba to act as a domain controller too.)
# The path below should be writable by all users so that their
# profile directory may be created the first time they log on
;[profiles]
;   comment = Users profiles
;   path = /home/samba/profiles
;   guest ok = no
;   browseable = no
;   create mask = 0600
;   directory mask = 0700

wins support = no
[printers]
        comment = All Printers
        browseable = no
        path = /var/spool/samba
        printable = yes
;       guest ok = no
;       read only = yes
        create mask = 0700

# Windows clients look for this share name as a source of downloadable
# printer drivers


;       writeable = no
;       browseable = yes
;       browseable = yes



[Data]  
        path = /media/data

Par la même occasion j'ai réinstaller totalement le serveur samba avec la commande

sudo apt-get autoremove samba

suivie de

sudo apt-get install samba

Mais rien n'y fait... J'ai également essayer de relancer les service à l'aide de

sudo service samba stop
sudo service samba start

la commande me retourne un numéro de processus que je n'ai pas retrouvé dans htop, je me demande donc si le serveur plante lors de son redémarage...

Merci beaucoup pour ton aide.

Re : Problèmes Samba après changement serveur en 14.04

Pour connaitre la version d'un package  :

dpkg -l | grep samba

Pour voir les logs samba (pourquoi pas nous les poster):

less /var/log/samba/log.smbd 

Pour ta configuration elle me semble incomplète, je ne vois pas la section [global]

Comme sa, je dirais que :

# By default, \\server\username shares can be connected to by anyone
# with access to the samba server.

Ceci peux aider : [doc]samba_smb.conf[/doc]
(http://doc.ubuntu-fr.org/samba_smb.conf)

Pourquoi cela ne marche pas avec la balise doc ? (le . ?)

Re : Problèmes Samba après changement serveur en 14.04

@mereej974,
correction au post initial, le changement de version était une installation fraîche abandonnant 12.04 en RAID1 et non une migration.
Voilà pour la version Samba:

 dpkg -l|grep samba
ii  samba                               2:4.1.6+dfsg-1ubuntu2.14.04.2 amd64        SMB/CIFS file, print, and login server for Unix

Pour le log, répétition continue de:

  failed to retrieve printer list: NT_STATUS_UNSUCCESSFUL
[2014/07/31 04:57:51.022756,  0] ../source3/printing/print_cups.c:151(cups_connect)
  Unable to connect to CUPS server localhost:631 - Bad file descriptor
[2014/07/31 04:57:51.022963,  0] ../source3/printing/print_cups.c:528(cups_async_callback)
  failed to retrieve printer list: NT_STATUS_UNSUCCESSFUL

Pour le fichier smb.conf, j'ai commencé avec un fichier tout neuf, j'ai ensuite repris l'ancien fichier de configuration de 12.04, je l'ai ensuite remplacé par un fichier qui marchait bien autre part et en adaptant les partages.
J'ai essayé avec ou sans netbios name, avec ou sans serveur WINS, aucun changement.
J'observe que le dossier /etc/samba ne comprend pas de fichier smb.conf.ucf-old, contrairement à auparavant.

Edit2: Sur les postes qui ne se connectent pas, la réponse est "Le partage xxx n'est pas accessible. Vous ne disposez peut-être pas des autorisations nécessaires..." Et cela, quel que soit le partage demandé et l'identifiant essayé (en correspondance avec les autorisations attribuées naturellement).
Tous les postes-client sont en Seven.
Pas de pare-feu installé, à part fail2ban en SSH.

Re : Problèmes Samba après changement serveur en 14.04

Après suppression de fail2ban, l'arborescence Samba réapparaît avec smbtree. Mais le groupe de travail est toujours affiché WORKSTATION.
L'accès aux partages sur les postes récalcitrants jusqu'ici redevient possible après leur redémarrage (reste encore à confirmer pour la totalité du réseau).
Le retour de smbstatus est maintenant normal.

Je me suis demandé, si je ne pourrais pas re-générer un smb.conf pour repartir à zéro et vois si ça fonctionne, mais je ne sais pas comment faire...

Merci pour votre aide

Re : Problèmes Samba après changement serveur en 14.04

Bonjour,

@sinbad83
peux tu partager ton smb.conf afin d'aider ceux à qui cela pourrait aider ?
Je pense que cela ne serait pas de trop pour thomasgaime.

Re : Problèmes Samba après changement serveur en 14.04

@mereej974,

je n'ai pas tout compris dans le problème Samba rencontré:
- en 12.04, fail2ban était installé, sans aucun souci côté Samba,
- sur un autre serveur en 14.04, fail2ban cohabite avec Samba sans interférer,
- c'est pareil chez moi,
- dans les trois cas, je n'avais activé que le filtrage SSH,
- comment expliquer que certains postes pouvaient accéder aux partages et d'autres pas ?

Je joins ici une partie simplifiée du smb.conf, il n'a rien de canonique. Je n'ai rien supprimé des longueurs sans intérêt:

#
# 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. 
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
#

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

[global]

## Browsing/Identification ###

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

# 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

Re : Problèmes Samba après changement serveur en 14.04

Bonsoir sinbad83,

je ne vois pas non plus le rapport entre un fail2ban et ton erreur d'accès à samba... surtout qu’apparemment il est configuré uniquement pour ssh.
Si tes logs samba sont toujours présentes, peut-être que cela nous éclairera ?
Je suis preneur de l'information.

Rien d'intéressant der nouveau à envoyer. Le log du post #8 ne concernait qu'un problème sans intérêt de liste d'imprimantes.
