1. Diretório visível somente para dono [RESOLVIDO]

Enviado em 09/06/2017 - 08:49h

Bom dia à todos.
Estou estudando samba e tenho o seguinte ambiente:
Tenho um compartilhamento em /sharing/particular
Dentro de "particular" eu tenho vários diretórios que nomeei com o nome dos usuários que criei no samba, ou seja, usuário cesar, tem um diretório chamado cesar dentro particular. Usuário leonardo, tem um diretório chamado leonardo dentro de particular e por aí vai.
Só que o que eu preciso é que quando um usuário acessar o diretório /sharing/particular não vejam os diretórios uns dos outros. Lembrando que nas permissões, deixei total para dono e para grupo e outros deixe sem permissão.
Estou pesquisando algo sobre variáveis, mas não consegui encontrar uma dica de como fazê-lo.
Obrigado.

O "/sharing/particular" é o diretório pai dos compartilhamentos?
Se sim, então nas definições dos diretórios filhos adicione a opção "access based share enum = yes"

Ex.:

[cesar]
path = /sharing/particular/cesar
valid users = cesar
access based share enum = yes
...

Isso mesmo. Fiz o que você disse, mas continuei visualizando todos os diretórios dos outros usuários.

Ok, sua versão dá suporte a essa opção. Poste seu "smb.conf".

#
# 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 = SAMBA

# 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

#### 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
log level = 1
# 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 ###########

#
# The following settings only takes effect if 'server role = primary
# classic domain controller', 'server role = backup domain controller'
# or '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)

# Another common choice is storing the profile in the user's home directory
# (this is Samba's default)

# 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

Você deve fazer mais ou menos assim:

1 - Dentro de "/sharing/particular" (o diretório "pai") você cria os diretórios "filhos":

/sharing/particular/fulano
/sharing/particular/ciclano
/sharing/particular/beltrano


2 - No "smb.conf" você deve definir os compartilhamentos particulares para cada usuário:

[fulano]
path = /sharing/particular/fulano
valid users = fulano
access based share enum = yes
...

[ciclano]
path = /sharing/particular/ciclano
valid users = ciclano
access based share enum = yes
...

[beltrano]
path = /sharing/particular/beltrano
valid users = beltrano
access based share enum = yes
...
Fazendo dessa forma vai dar certo.

Os usuários continuam se enxergando. Fiz do jeito que você falou. Não alterou nada.

Ah, esqueci de mencionar que pra que isso seja possível, você deve utilizar acesso com autenticação no Samba.

Olá. Bom dia.
Então, isso já está acontecendo. O Sistema já me pede usuário e senha quando eu acesso os diretórios do Samba pelo Windows. Seria isso mesmo?

Aqui onde trabalho, montei um servidor Samba e ele funciona perfeitamente do jeito que você deseja! Os usuários só visualizam os diretórios nos quais eles são "valid users".
Essa é uma parte do meu "smb.conf":
