Os explicamos cómo instalar y configurar Samba (mediante SMB permite compartir archivos e impresoras en Linux para acceso desde Windows) y Swat (herramienta de administración Web de Samba) en Linux Ubuntu. Os explicamos cómo compartir una carpeta en Linux para que sea accesible desde Windows.

INSTALACIÓN Y CONFIGURACIÓN DE SAMBA Y SWAT EN LINUX UBUNTU 6.10

Samba es una aplicación Unix/linux que, mediante el protocolo SMB (Server Message Block), permite los siguientes servicios en un PC con Unix/Linux:

• Compartir uno o más sistemas de archivos.
• Compartir impresoras, instaladas tanto en el servidor como en los clientes.
• Ayudar a los clientes, con visualizador de Clientes de Red.
• Autentificar clientes logeándose contra un dominio Windows.
• Proporcionar o asistir con un servidor de resolución de nombres WINS.

De esta forma, un equipo Linux con Samba instalado y configurado podrá pasar como si de un equipo Windows se tratara (en cuanto a recursos compartidos). Se podrá acceder desde un equipo Windows a las carpetas/impresoras compartidas en un equipo Linux con Samba como si de dos equipos Windows se tratara. De esta forma no será necesario transferir ficheros mediante ftp u otros métodos más pesado, será suficiente con acceder a "Mis sitios de red" y buscar el equipo Linux.

En primer lugar deberemos instalar Samba y Swat en Linux, pues normalmente no vienen instalados por defecto. Para instalarlo (en el caso de distribuciones Debian, en concreto Ubuntu) abriremos una ventana de Terminal, desde "Aplicaciones" - "Accesorios" - "Terminal". En esta ventana escribiremos:

sudo apt-get install inetd samba samba-common smbclient swat

Nota 1: colocando "sudo" delante del comando "apt-get" no será necesario iniciar sesión con superusuario root, puede que nos pida la contraseña del usuario root para ejecutar el comando apt-get.

Nota 2: si no encuentra alguno de los paquetes a instalar será necesario añadir el repositorio correspondiente en el fichero /etc/apt/sources.list, puede ver el contenido de este fichero pulsando aquí. Si el contenido no es el mismo puede hacer una copia del actual y reemplazarlo con el que le mostramos abajo, después es conveniente actualizar la caché para poder instalar Samba. Para actualizar la caché pondremos:

apt-get update

Puede ver el resultado del comando pulsando aquí.

Una vez instalado Samba y Swat, podremos visualizar el archivo de configuración de Samba con el comando:

cat /etc/samba/smb.conf

Puede ver el contenido del fichero smb.conf original pulsando aquí.

A continuación crearemos un usuario para Samba mediante el comando:

smbpasswd -a nombreusuario

nos pedirá la contraseña y reintroducirla:

New SMB password:
Retype new SMB password:

Es conveniente reiniciar el equipo, aunque a veces funciona sin hacerlo. Llegados a este punto accederemos a la administración Web de Samba (Swat), para ello abriremos Firefox (navegador Web) y escribiremos en el campo de dirección:

http://localhost:901

nos pedirá usuario y contraseña, para poder configurar Samba de forma completa deberemos acceder con el superusuario root:

La ventana inicial de Swat tiene este aspecto:

Cabe mencionar que Swat es accesible desde cualquier PC de la red con Windows o Linux, introduciendo la IP del equipo Linux o el nombre de red (si ya hemos configurado Samba) con Samba en Internet Explorer (o el navegador de Internet que utilicemos):

Desde esta ventana podremos compartir carpetas de Linux para que estén visibles en la red de Windows, compartir impresoras, administrar usuarios, etc. Todo ello de forma relativamente sencilla.

En primer lugar indicaremos el grupo de trabajo, el nombre NetBios del equipo en la red, etc. Para ello pulsaremos en el icono "Globals":

Indicaremos el grupo de trabajo en "Workgroup", el nombre de red en "netbios name" y otras opciones. Una vez modificadas pulsaremos "Commit Change" para guardar y aplicar los cambios:

Pulsando el icono "Status" podremos ver los usuarios conectados, los usuarios denegados, cerrar conexión de usuarios, etc:

Os explicaremos a continuación cómo compartir una carpeta con Swat. Para ello accederemos a la administración web de Samba (Swat) tal y como hemos indicado anteriormente, pulsaremos en el icono "Shares":

para compartir una carpeta existente en Linux pulsaremos en el cuadro de textoque aparece a la derecha de "Create Share" e introduciremos el nombre que tendrá el recurso compartido, en nuestro caso "compartida_linux", pulsaremos en "Create Share" para mostrar las opciones de configuración del nuevo recurso compartido:

El dato obligario para compartir una carpeta es "path" (la ruta de la carpeta existente en linux que queramos compartir, en nuestro caso /home/alonso/Desktop/compartida):

Pero, por supuesto, también podremos indicar un comentario aclaratorio en "comment", si se permitirá modificación de los datos de la carpeta "read only", podremos indicar también los equipos de la red a los que permitiremos el acceso en "hosts allow", los equipos a los que les denegaremos el acceso "hosts deny", también podremos indicar si queremos activar los log (auditoria de acceso) para esta carpeta en "EventLog Options" - "available" y otras muchas opciones. Podremos mostrar las opciones avanzadas pulsando en el botón "Avanced" de la parte superior de la ventana "Share Parameters". Tras introducir las opciones de la carpeta compartida pulsaremos el botón "Commit Changes" para guardar y aplicar los cambios.

Si desea ver el contenido del fichero smb.conf después de aplicar los cambios (de crear una carpeta compartida) pulse aquí.

Para probar el acceso a la carpeta compartida desde un equipo con Windows XP, accederemos a "Mis sitios de red" - "Toda la red" - "Red de Microsoft Windows" y haremos doble clic sobre el grupo de trabajo al que pertenezca el equipo de Linux:

dentro de este grupo nos aparecerá nuestro equipo Linux (en nuestro caso "pclinux server (Samba, Ubuntu) (pclinux)"):

Haciendo doble clic sobre este equipo nos aparecerán las carpetas e impresoras compartidas de Linux. También es perfectamente accesible introduciendo el nombre del equipo linux en "Inicio" - "Ejecutar" de la siguiente forma:

\nombre_equipo_linux

Lógicamente, dentro de "compartida_linux" podremos ver los ficheros que hayamos copiado en Linux, en la carpeta:

/home/alonso/Desktop/compartida

por supuesto, podremos trabajar en esta carpeta como si de una carpeta Windows se tratara, podremos copiar, pegar, eliminar, modificar los ficheros existentes en ella (según los permisos que le hayamos dado):

#
# 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
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentary and a ; for parts of the config file that you
# may wish to enable
#
# 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 = MSHOME

# 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 = 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 = 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.

# 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.

# 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 = \%Nprofiles\%U
# Another common choice is storing the profile in the user's home directory
; logon path = \%N\%Uprofile

# 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

# also give this right to other users to add drivers and set printer
# properties
; printer admin = @lpadmin

# on a per machine basis. The %m gets replaced with the netbios name
# of the machine that is connecting

Descripción: a LanManager-like file and printer server for Unix
The Samba software suite is a collection of programs that implements the SMB/CIFS protocol for unix systems, allowing you to
serve files and printers to Windows, NT, OS/2 and DOS clients. This protocol is sometimes also referred to as the LanManager
or NetBIOS protocol.

This package contains all the components necessary to turn your Debian GNU/Linux box into a powerful file and printer
server.

Currently, the Samba Debian packages consist of the following:

samba - LanManager-like file and printer server for Unix.
samba-common - Samba common files used by both the server and the client.
smbclient - LanManager-like simple client for Unix.
swat - Samba Web Administration Tool
samba-doc - Samba documentation.
samba-doc-pdf - Samba documentation in PDF format.
smbfs - Mount and umount commands for the smbfs (kernels 2.2.x and above).
libpam-smbpass - pluggable authentication module for SMB/CIFS password database
libsmbclient - Shared library that allows applications to talk to SMB/CIFS servers
libsmbclient-dev - libsmbclient shared libraries
winbind: Service to resolve user and group information from Windows NT servers
python2.4-samba: Python bindings that allow access to various aspects of Samba

It is possible to install a subset of these packages depending on your particular needs. For example, to access other
SMB/CIFS servers you should only need the smbclient and samba-common packages.
