Linux Samba PDC – Domain Model

Linux Samba PDC – Domain Model

SAMBA 类似于windows 的AD的功能。

SAMBA 有两种连线模式： Peer / Peer 和 Domain Model

Domain Model 模式就如同windows 中的 DC域控制器。这里的Samab 的起域主控制器的作用。网络内的所有电脑的帐号与密码都在PDC（Primary Domain Control）中，网络中的所有电脑登入系统都能通过PCD这台主控制器通行检测的。只有通PDC的检测和拿到相应权后再能做相应的操作。

Samba Domain Model

SAMBA PDC (Samba Domain Model) 配置：

注意，smb.conf 配置文件中的 # 和; 是注释符号

(原配置中我们做修改的部分黄底背景)

一. 设置lmhosts 或/etc/hosts 对应的netbios name 和IP, 如是电脑为DHCP获取IP,可以跑过这一部分。

[root@sql root]# vi /etc/samba/lmhosts

127.0.0.1 localhost

192.168.100.80 DBA

192.168.100.81 pc01

~

2.设置 smb.conf

[root@sql root]# vi /etc/samba/smb.conf

# 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 (perhaps too

# many!) 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 commentry 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]

# workgroup = NT-Domain-Name or Workgroup-Name

workgroup = SQL.DBA.COM

netbios name = DBA

# server string is the equivalent of the NT Description field

server string = samba server

# This option is important for security. It allows you to restrict

# connections to machines which are on your local network. The

# following example restricts access to two C class networks and

# the "loopback" interface. For more examples of the syntax see

# the smb.conf man page

hosts allow = 192.168.1. 192.168.2. 192.168.100. 127.

# if you want to automatically load your printer list rather

# than setting them up individually then you'll need this

printcap name = /etc/printcap

load printers = yes

# It should not be necessary to spell out the print system type unless

# yours is non-standard. Currently supported print systems include:

# bsd, sysv, plp, lprng, aix, hpux, qnx, cups

printing = cups

# Uncomment this if you want a guest account, you must add this to /etc/passwd

# otherwise the user "nobody" is used

# this tells Samba to use a separate log file for each machine

# that connects

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

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

max log size = 0

# Security mode. Most people will want user level security. See

# security_level.txt for details.

security = user

# Use password server option only with security = server

# The argument list may include:

# password server = My_PDC_Name [My_BDC_Name] [My_Next_BDC_Name]

# or to auto-locate the domain controller/s

# password server = *

; password server = <NT-Server-Name>

# Password Level allows matching of _n_ characters of the password for

# all combinations of upper and lower case.

; password level = 8

; username level = 8

# You may wish to use password encryption. Please read

# ENCRYPTION.txt, Win95.txt and WinNT.txt in the Samba documentation.

# Do not enable this option unless you have read those documents

encrypt passwords = yes

smb passwd file = /etc/samba/smbpasswd

# The following is needed to keep smbclient from spouting spurious errors

# when Samba is built with support for SSL.

; ssl CA certFile = /usr/share/ssl/certs/ca-bundle.crt

# The following are needed to allow password changing from Windows to

# update the Linux system password also.

# NOTE: Use these with 'encrypt passwords' and 'smb passwd file' above.

# NOTE2: You do NOT need these to allow workstations to change only

# the encrypted SMB passwords. They allow the Unix password

# to be kept in sync with the SMB password.

unix password sync = Yes

passwd program = /usr/bin/passwd %u

passwd chat = *New*password* %n\n *Retype*new*password* %n\n *passwd:*all*authentication*tokens*updated*successfully*

# You can use PAM's password change control flag for Samba. If

# enabled, then PAM will be used for password changes when requested

# by an SMB client instead of the program listed in passwd program.

# It should be possible to enable this without changing your passwd

# chat parameter for most setups.

pam password change = yes

# Unix users can map to different SMB User names

; username map = /etc/samba/smbusers

# 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 = /etc/samba/smb.conf.%m

# This parameter will control whether or not Samba should obey PAM's

# account and session management directives. The default behavior is

# to use PAM for clear text authentication only and to ignore any

# account or session management. Note that Samba always ignores PAM

# for authentication in the case of encrypt passwords = yes

obey pam restrictions = yes

# Most people will find that this option gives better performance.

# See speed.txt and the manual pages for details

socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192

# Configure Samba to use multiple interfaces

# If you have multiple network interfaces then you must list them

# here. See the man page for details.

# a specific host or from / to a whole subnet (see below)

; remote browse sync = 192.168.3.25 192.168.5.255

# Cause this host to announce itself to local subnets here

; remote announce = 192.168.1.255 192.168.2.44

# Browser Control Options:

# set local master to no if you don't want Samba to become a master

# browser on your network. Otherwise the normal election rules apply

local master = yes

# OS Level determines the precedence of this server in master browser

# elections. The default value should be reasonable

os level = 64

# Domain Master specifies Samba to be the Domain Master Browser. This

# allows Samba to collate browse lists between subnets. Don't use this

# if you already have a Windows NT domain controller doing this job

domain master = yes

# Preferred Master causes Samba to force a local browser election on startup

# and gives it a slightly higher chance of winning the election

preferred master = yes

# Enable this if you want Samba to be a domain logon server for

# Windows95 workstations.

domain logons = yes

logon drive = K:

time server = yes

admin users = root

# if you enable domain logons then you may want a per-machine or

# per user logon script

# run a specific logon batch file per workstation (machine)

logon script = startup.bat

# run a specific logon batch file per username

# Where to store roving profiles (only for Win95 and WinNT)

# %L substitutes for this servers netbios name, %U is username

# You must uncomment the [Profiles] share below

# Windows Internet Name Serving Support Section:

# WINS Support - Tells the NMBD component of Samba to enable it's WINS Server

wins support = yes

# 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

# WINS Proxy - Tells Samba to answer 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.

; wins proxy = yes

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names

# via DNS nslookups. The built-in default for versions 1.9.17 is yes,

# this has been changed in version 1.9.18 to no.

; username map = /etc/samba/smbusers

dns proxy = no

# Case Preservation can be handy - system default is _no_

# NOTE: These can be set on a per share basis

; preserve case = no

; short preserve case = no

# Default case is normally upper case for all DOS files

; default case = lower

# Be very careful with case sensitivity - it can break things!

; case sensitive = no
