Samba Help (not dancing)

At home I have a 2003 domain. I wanted a NAS to store files on the network but decided with the amount of spare drives I have it would be better to juts build a network server…

So now I have a Ubuntu system that I want to access from my PC’s.

Here is the information that I think is important. If you need more info please ask

  1. The user accounts on the Linux system use the same names and passwords and the domain

  2. uname -a shows
    Linux dumpster 2.6.24-19-generic #1 SMP Fri Jul 11 23:41:49 UTC 2008 i686 GNU/Linux

  3. Current mount info
    emanuel@dumpster:~ mount /dev/sda1 on / type ext3 (rw,relatime,errors=remount-ro) proc on /proc type proc (rw,noexec,nosuid,nodev) /sys on /sys type sysfs (rw,noexec,nosuid,nodev) varrun on /var/run type tmpfs (rw,noexec,nosuid,nodev,mode=0755) varlock on /var/lock type tmpfs (rw,noexec,nosuid,nodev,mode=1777) udev on /dev type tmpfs (rw,mode=0755) devshm on /dev/shm type tmpfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) lrm on /lib/modules/2.6.24-19-generic/volatile type tmpfs (rw) /dev/mapper/storage-data on /var/shared type reiserfs (rw) securityfs on /sys/kernel/security type securityfs (rw) binfmt_misc on /proc/sys/fs/binfmt_misc type binfmt_misc (rw,noexec,nosuid,nodev) /dev/sdd1 on /media/disk type ext2 (rw,nosuid,nodev,uhelper=hal) emanuel@dumpster:~

  4. The location of the share on the Ubuntu system in /var/shared

emanuel@dumpster:/var/shared$ ls -la
total 5
drwxr-xr-x 10 root root 232 2008-05-11 20:44 .

Ok now for my smb.conf file which I’m sure has errors because I have no clue what I’m doing

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


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

Winbind settings

For testing

workgroup = levy.home


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

server string is the equivalent of the NT Description field

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.

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

to IP addresses

; name resolve order = lmhosts host wins bcast


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 = 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


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

that connects

Cap the size of the individual log files (in KiB).

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.

Do something sensible when Samba crashes: mail the admin a backtrace

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

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

in this server for every user accessing the server. See


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.

If you are using encrypted passwords, Samba will need to know what

password database type you are using.

guest account = nobody

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.

For Unix password sync to work on a Debian GNU/Linux system, the following

parameters must be set (thanks to Ian Kahan <<> for

sending the correct chat script for the passwd program in Debian Sarge).

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’.

This option controls how nsuccessful authentication attempts are mapped

to anonymous connections

########## 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

############ 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/Samba3-HOWTO/speed.html

for details

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


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

The following was the default behaviour in sarge,

but samba upstream reverted the default because it might induce

performance issues in large organizations.

See Debian bug #368251 for some of the consequences of not

having this setting and smb.conf(5) for details.

; winbind enum groups = yes
; winbind enum users = yes

Setup usershare options to enable non-root users to share folders

with the net usershare command.

Maximum number of usershare. 0 (default) means that usershare is disabled.

usershare max shares = 998

Allow users who’ve been granted usershare privileges to create

public shares, not just authenticated ones

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

Un-comment the following (and tweak the other settings below to suit)

to enable the default home directory shares. This will share each

user’s home directory as \server\username

; comment = Home Directories
; browseable = no

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

next parameter to ‘no’ if you want to be able to write to them.

; read only = 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 = 0777

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 = 0777

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

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.)

; comment = Network Logon Service
; path = /home/samba/netlogon
; guest ok = yes
; read only = yes
; share modes = no

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

; comment = Users profiles
; path = /home/samba/profiles
; guest ok = no
; browseable = no
; create mask = 0600
; directory mask = 0700

comment = Music
writable = yes
public = yes
path = /var/shared/Music
available = yes
browseable = yes
guest ok = yes
guest account = nobody
comment = Video Files
writable = yes
public = yes
path = /var/shared/Video
available = yes
browseable = yes
guest ok = yes
guest account = nobody
comment = E-Books and Documentation
writable = yes
public = yes
path = /var/shared/Books
available = yes
browseable = yes
guest ok = yes
guest account = nobody

comment = Common Files
writable = yes
public = yes
path = /var/shared/common
available = yes
browseable = yes
guest ok = yes
guest account = nobody

comment = Applications
writable = yes
public = yes
path = /var/shared/Applications
available = yes
guest account = nobody
comment = Karaokes
writable = yes
public = yes
path = /var/shared/Karaoke
available = yes
guest ok = yes
browseable = yes
guest account = nobody

What I want to happen is have any user on my local network be able to access any shared folder on the Ubuntu system.
