[Resolu]PB Samba / autorisations d'écriture

Bonjour,
voilà ma situation:
Debian Sarge 2.6.18-4-686 / Serveur en passerelle reseau (Internet > eth0 pc debian | eth1 > switch - autres pc)

Mon problème est le suivant, je viens d’installer Samba et je veux donc partager plusieurs dossiers, le partage fonctionne correctement, sauf que je ne peux pas écrire sur les dossiers partagé(sauf le /home/partage/)

j’ai crée un user “partage” avec lequel je me connecte sur les dossiers partagé j’ai fais un “smbpasswd -a partage”…
voilà mon fichier de conf smb.conf:

[code][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

What naming service and in what order should we use to resolve host names

to IP addresses

; name resolve order = lmhosts host wins bcast

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 = 192.168.0.1/30 eth1

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 = true

Debugging/Accounting

This tells Samba to use a separate log file for each machine

that connects

log file = /var/log/samba/log.%m

Put a capping on the size of the log files (in Kb).

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 #######

“security = user” is always a good idea. This will require a Unix account

in this server for every user accessing the server. See

/usr/share/doc/samba-doc/htmldocs/Samba-HOWTO-Collection/ServerType.html

in the samba-doc package for details.

security = user

You may wish to use password encryption. See the section on

‘encrypt passwords’ in the smb.conf(5) manpage before enabling.

encrypt passwords = true

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

; guest account = nobody
share modes = yes
invalid users = root

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\sUNIX\spassword: %n\n Retype\snew\sUNIX\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 = no

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

Is this machine able to authenticate users. Both PDC and BDC

must have this setting enabled. If you are the BDC you must

change the ‘domain master’ setting to no

; domain logons = yes

The following setting only takes effect if ‘domain logons’ is set

It specifies the location of the user’s profile directory

from the client point of view)

The following required a [profiles] share to be setup on the

samba server (see below)

; logon path = \%N\profiles%U

Another common choice is storing the profile in the user’s home directory

; logon path = \%N%U\profile

The following setting only takes effect if ‘domain logons’ is set

It specifies the location of a user’s home directory (from the client

point of view)

; logon drive = H:
; logon home = \%N%U

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

; logon script = logon.cmd

This allows Unix users to be created on the domain controller via the SAMR

RPC pipe. The example command creates a user account with a disabled Unix

password; please adapt to your needs

; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos “” %u

########## Printing ##########

If you want to automatically load your printer list rather

than setting them up individually then you’ll need this

; load printers = yes

lpr(ng) printing. You may wish to override the location of the

printcap file

; printing = bsd
; printcap name = /etc/printcap

CUPS printing. See also the cupsaddsmb(8) manpage in the

cupsys-client package.

; printing = cups
; printcap name = cups

When using [print$], root is implicitly a ‘printer admin’, but you can

also give this right to other users to add drivers and set printer

properties

; printer admin = @ntadmin

############ Misc ############

Using the following line enables you to customise your configuration

on a per machine basis. The %m gets replaced with the netbios name

of the machine that is connecting

; include = /home/samba/etc/smb.conf.%m

Most people will find that this option gives better performance.

See smb.conf(5) and /usr/share/doc/samba-doc/htmldocs/speed.html

for details

You may want to add the following on a Linux system:

SO_RCVBUF=8192 SO_SNDBUF=8192

socket options = TCP_NODELAY

The following parameter is useful only if you have the linpopup package

installed. The samba maintainer and the linpopup maintainer are

working to ease installation and configuration of linpopup and samba.

; message command = /bin/sh -c ‘/usr/bin/linpopup “%f” “%m” %s; rm %s’ &

Domain Master specifies Samba to be the Domain Master Browser. If this

machine will be configured as a BDC (a secondary logon server), you

must set this to ‘no’; otherwise, the default behavior is recommended.

; domain master = auto

Some defaults for winbind (make sure you’re not using the ranges

for something else.)

; idmap uid = 10000-20000
; idmap gid = 10000-20000
; template shell = /bin/bash

#======================= Share Definitions =======================

[homes]
comment = Home Directories
browseable = no

By default, the home directories are exported read-only. Change next

parameter to ‘yes’ if you want to be able to write to them.

writable = yes

File creation mask is set to 0700 for security reasons. If you want to

create files with group=rw permissions, set next parameter to 0775.

create mask = 0740

Directory creation mask is set to 0700 for security reasons. If you want to

create dirs. with group=rw permissions, set next parameter to 0775.

directory mask = 0740

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
; writable = no
; share modes = no

[partage]
comment = partage
browseable = yes
path = /home/partage/
public = no
writable = yes
share modes = yes
create mode = 0755
valid users = partage

[datas]
comment = partage
browseable = yes
path = /media/datas/
public = no
writable = yes
share modes = yes
create mode = 0755
valid users = partage

[web]
comment = Site
browseable = yes
path = /var/www/
public = no
writable = yes
share modes = yes
create mode = 0755
valid users = partage

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

[printers]
comment = All Printers
browseable = no
path = /tmp
printable = yes
public = no
writable = no
create mode = 0700

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

printer drivers

[print$]
comment = Printer Drivers
path = /var/lib/samba/printers
browseable = yes
read only = yes
guest ok = no

Uncomment to allow remote administration of Windows print drivers.

Replace ‘ntadmin’ with the name of the group your admin users are

members of.

; write list = root, @ntadmin

A sample share for sharing your CD-ROM with others.

;[cdrom]
; comment = Samba server’s CD-ROM
; writable = no
; locking = no
; path = /cdrom
; public = yes

The next two parameters show how to auto-mount a CD-ROM when the

cdrom share is accesed. For this to work /etc/fstab must contain

an entry like this:

/dev/scd0 /cdrom iso9660 defaults,noauto,ro,user 0 0

The CD-ROM gets unmounted automatically after the connection to the

If you don’t want to use auto-mounting/unmounting make sure the CD

is mounted on /cdrom

; preexec = /bin/mount /cdrom
; postexec = /bin/umount /cdrom[/code]

Voilà les chmod sur les différents dossiers

drwxr-xr-x 3 root root 4.0K Jul 6 18:44 www
drwxr-x— 4 root root 32K Jul 6 16:52 datas

Qu’est ce qui fait que je ne puisse pas écrire ds les dossiers? Quel est la meilleure façcon de partager des dossiers en ayant le droit d’écriture , le tout assé sécurisé?
Si vous voulez plus de details dites le moi.
Merci +

tu es sûr que tu te connectes bien en tant que “partage” et pas en anonyme ?
mets un map to guest = Never dans [general] pour en être sûr.
peut être aussi qu’un smbpasswd -e partage pour activer …
