This is the main Samba configuration file. For detailed information about the

options listed here, refer to the smb.conf(5) manual page. Samba has a huge

number of configurable options, most of which are not shown in this example.

The Official Samba 3.2.x HOWTO and Reference Guide contains step-by-step

guides for installing, configuring, and using Samba:

http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf

The Samba-3 by Example guide has working examples for smb.conf. This guide is

generated daily: http://www.samba.org/samba/docs/Samba-Guide.pdf

In this file, lines starting with a semicolon (:wink: or a hash (#) are

comments and are ignored. This file uses hashes to denote commentary and

semicolons for parts of the file you may wish to configure.

Note: Run the “testparm” command after modifying this file to check for basic

syntax errors.

Security-Enhanced Linux (SELinux) Notes:

Turn the samba_domain_controller Boolean on to allow Samba to use the useradd

and groupadd family of binaries. Run the following command as the root user to

turn this Boolean on:

setsebool -P samba_domain_controller on

Turn the samba_enable_home_dirs Boolean on if you want to share home

directories via Samba. Run the following command as the root user to turn this

Boolean on:

setsebool -P samba_enable_home_dirs on

If you create a new directory, such as a new top-level directory, label it

with samba_share_t so that SELinux allows Samba to read and write to it. Do

not label system directories, such as /etc/ and /home/, with samba_share_t, as

such directories should already have an SELinux label.

Run the “ls -ldZ /path/to/directory” command to view the current SELinux

label for a given directory.

Set SELinux labels only on files and directories you have created. Use the

chcon command to temporarily change a label:

chcon -t samba_share_t /path/to/directory

Changes made via chcon are lost when the file system is relabeled or commands

such as restorecon are run.

Use the samba_export_all_ro or samba_export_all_rw Boolean to share system

directories. To share such directories and only allow read-only permissions:

setsebool -P samba_export_all_ro on

To share such directories and allow read and write permissions:

setsebool -P samba_export_all_rw on

To run scripts (preexec/root prexec/print command/…), copy them to the

/var/lib/samba/scripts/ directory so that SELinux will allow smbd to run them.

Note that if you move the scripts to /var/lib/samba/scripts/, they retain

their existing SELinux labels, which may be labels that SELinux does not allow

smbd to run. Copying the scripts will result in the correct SELinux labels.

Run the “restorecon -R -v /var/lib/samba/scripts” command as the root user to

apply the correct SELinux labels to these files.

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

[global]

----------------------- Network-Related Options -------------------------

workgroup = the Windows NT domain name or workgroup name, for example, MYGROUP.

server string = the equivalent of the Windows NT Description field.

netbios name = used to specify a server name that is not tied to the hostname.

interfaces = used to configure Samba to listen on multiple network interfaces.

If you have multiple interfaces, you can use the “interfaces =” option to

configure which of those interfaces Samba listens on. Never omit the localhost

interface (lo).

hosts allow = the hosts allowed to connect. This option can also be used on a

per-share basis.

hosts deny = the hosts not allowed to connect. This option can also be used on

a per-share basis.

max protocol = used to define the supported protocol. The default is NT1. You

can set it to SMB2 if you want experimental SMB2 support.

workgroup = mygroup
server string = Samba Server Version %v

; netbios name = MYSERVER

; interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24
; hosts allow = 127. 192.168.12. 192.168.13.

; max protocol = SMB2

--------------------------- Logging Options -----------------------------

log file = specify where log files are written to and how they are split.

max log size = specify the maximum size log files are allowed to reach. Log

files are rotated when they reach the size specified with “max log size”.

# log files split per-machine:
log file = /var/log/samba/log.%m
# maximum size of 50KB per log file, then rotate:
max log size = 50

----------------------- Standalone Server Options ------------------------

security = the mode Samba runs in. This can be set to user, share

(deprecated), or server (deprecated).

passdb backend = the backend used to store user information in. New

installations should use either tdbsam or ldapsam. No additional configuration

is required for tdbsam. The “smbpasswd” utility is available for backwards

compatibility.

security = user

; passdb backend = tdbsam

----------------------- Domain Members Options ------------------------

security = must be set to domain or ads.

passdb backend = the backend used to store user information in. New

installations should use either tdbsam or ldapsam. No additional configuration

is required for tdbsam. The “smbpasswd” utility is available for backwards

compatibility.

realm = only use the realm option when the “security = ads” option is set.

The realm option specifies the Active Directory realm the host is a part of.

password server = only use this option when the “security = server”

option is set, or if you cannot use DNS to locate a Domain Controller. The

argument list can include My_PDC_Name, [My_BDC_Name], and [My_Next_BDC_Name]:

password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]

Use “password server = *” to automatically locate Domain Controllers.

; realm = MY_REALM

; password server =

----------------------- Domain Controller Options ------------------------

security = must be set to user for domain controllers.

passdb backend = the backend used to store user information in. New

installations should use either tdbsam or ldapsam. No additional configuration

is required for tdbsam. The “smbpasswd” utility is available for backwards

compatibility.

domain master = specifies Samba to be the Domain Master Browser, allowing

Samba to collate browse lists between subnets. Do not use the “domain master”

option if you already have a Windows NT domain controller performing this task.

domain logons = allows Samba to provide a network logon service for Windows

workstations.

logon script = specifies a script to run at login time on the client. These

scripts must be provided in a share named NETLOGON.

logon path = specifies (with a UNC path) where user profiles are stored.

; domain master = yes
; domain logons = yes

# the following login script name is determined by the machine name
# (%m):

; logon script = %m.bat
# the following login script name is determined by the UNIX user used:
; logon script = %u.bat
; logon path = \%L\Profiles%u
# use an empty path to disable profile support:
; logon path =

# various scripts can be used on a domain controller or a stand-alone
# machine to add or delete corresponding UNIX accounts:

; add user script = /usr/sbin/useradd “%u” -n -g users
; add group script = /usr/sbin/groupadd “%g”
; add machine script = /usr/sbin/useradd -n -c “Workstation (%u)” -M -d /nohome -s /bin/false “%u”
; delete user script = /usr/sbin/userdel “%u”
; delete user from group script = /usr/sbin/userdel “%u” “%g”
; delete group script = /usr/sbin/groupdel “%g”

----------------------- Browser Control Options ----------------------------

local master = when set to no, Samba does not become the master browser on

your network. When set to yes, normal election rules apply.

os level = determines the precedence the server has in master browser

elections. The default value should be reasonable.

preferred master = when set to yes, Samba forces a local browser election at

start up (and gives itself a slightly higher chance of winning the election).

; local master = no
; os level = 33
; preferred master = yes

#----------------------------- Name Resolution -------------------------------

This section details the support for the Windows Internet Name Service (WINS).

Note: Samba can be either a WINS server or a WINS client, but not both.

wins support = when set to yes, the NMBD component of Samba enables its WINS

server.

wins server = tells the NMBD component of Samba to be a WINS client.

wins proxy = when set to yes, Samba answers name resolution queries on behalf

of a non WINS capable client. For this to work, there must be at least one

WINS server on the network. The default is no.

dns proxy = when set to yes, Samba attempts to resolve NetBIOS names via DNS

nslookups.

; wins support = yes
; wins server = w.x.y.z
; wins proxy = yes

; dns proxy = yes

--------------------------- Printing Options -----------------------------

The options in this section allow you to configure a non-default printing

system.

load printers = when set you yes, the list of printers is automatically

loaded, rather than setting them up individually.

cups options = allows you to pass options to the CUPS library. Setting this

option to raw, for example, allows you to use drivers on your Windows clients.

printcap name = used to specify an alternative printcap file.

; load printers = yes
cups options = raw

; printcap name = /etc/printcap
# obtain a list of printers automatically on UNIX System V systems:
; printcap name = lpstat
; printing = cups

--------------------------- File System Options ---------------------------

The options in this section can be un-commented if the file system supports

extended attributes, and those attributes are enabled (usually via the

“user_xattr” mount option). These options allow the administrator to specify

that DOS attributes are stored in extended attributes and also make sure that

Samba does not change the permission bits.

Note: These options can be used on a per-share basis. Setting them globally

(in the [global] section) makes them the default for all shares.

; map archive = no
; map hidden = no
; map read only = no
; map system = no
; encrypt passwords = yes
; guest ok = no
; guest account = nobody
; store dos attributes = yes

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

[homes]
comment = Home Directories
browseable = no
writable = yes
; valid users = %S
; valid users = MYDOMAIN%S

[printers]
comment = All Printers
path = /var/spool/samba
browseable = no
; guest ok = no
; writable = No
printable = yes

Un-comment the following and create the netlogon directory for Domain Logons:

; [netlogon]
; comment = Network Logon Service
; path = /var/lib/samba/netlogon
; guest ok = yes
; writable = no
; share modes = no

Un-comment the following to provide a specific roving profile share.

The default is to use the user’s home directory:

; [Profiles]
; path = /var/lib/samba/profiles
; browseable = no
; guest ok = yes

A publicly accessible directory that is read only, except for users in the

“staff” group (which have write permissions):

; [public]
; comment = Public Stuff
; path = /home/samba
; public = yes
; writable = yes
; printable = no
; write list = +staff

[Studio Moda]
comment = Cartella Studio Moda
path = /nfs
read only = no
; browseable = yes
valid users = paolo
