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 = user

 

# Use password server option only with security = server

# The argument list may include:

# 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.

# 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.

# 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.

;   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

# 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)

# 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

;[pchome]

;  comment = PC Directories

;  path = /usr/local/pc/%m

;  public = no

;  writable = yes

 

# A publicly accessible directory, read/write to all users. Note that all files

# created in the directory by users will be owned by the default user, so

2. 配置检测

[root@sql root]# testparm

 

3.重启samba 服务

[root@sql root]# /etc/init.d/smb restart  或  [root@sql root]# service smb restart

 

 

5. 创建相关资料

 

1) 建立所需要的文档资料

[root@sql root]# mkdir -p /home/samba/netlogon

 

2）创建帐号所需要的目录信息

[root@sql root]# vi /home/samba/netlogon/startup.bat

net time //dba /set /yes

net use K: /home

net use L: //dba/temp

 

3）转换成dos 格式供windows 系统使用

[root@sql root]# unix2dos /home/samba/netlogon/startup.bat

 

4）查看转换后的结果

[root@sql root]# cat -A /home/samba/netlogon/startup.bat

net time //sql /set /yes^M$

net use K: /home^M$

net use L: //sql/temp^M$

^M$

 

5) 建立帐号所存放的个人文件信息资料

[root@sql root]# mkdir -p /home/samba/profiles

（注意：此文件会涉及到客端login 域的一些权限的文件，可以根据情况用chmod  或 chown 来对此文件夹进给授权

(权限问题可能引发下面的错误)

 

 

 

 

6).添加帐号

 

首先添加的是root帐户，把root加入到smb帐户中

[root@sql root]# smbpasswd -a root

这一步很重要，因为后面的加入域要用到有管理员的帐号加入域的权限，否则用普通用户好像不能顺利加入域

 

[root@sql root]# useradd lilo

 

7).为添加的帐号设置密码

[root@sql root]# passwd lilo

 

8).将帐号添加为SAMBA用户

[root@sql root]# smbpasswd –a lilo

New SMB password:

Retype new SMB password

Added user lilo

 

9）添加机器帐号

[root@sql samba]# useradd -M -s /sbin/nologin -d /dev/null pc01$

（机器名后面一定加上$ 符号，它标识为信任帐户

 

10)将机器添加到 /etc/samba/smbpasswd

[root@sql samba]# smbpasswd -a -m pc01$

 

6. 加入域

1)将计算机加入到域

 

 

 

 

2）通过root 进行域网络验证

 

 

3）这里提示找不到计算帐户，不用理它，真上计算机名和域进入下一步

 

 

 

4)如果下一步发生以下的错误，可能是你的smb 服务没有启来，也有可能是你的named 的服务没有启来。尝试进行如下操作。

-> #service named restart

    #service smb restart

 

->或者客户端点击开始>运行>services.msc ， 停止IPSEC service ，再重试加入域

 

->查看客户端日志信息： c:/windows/debug 下的Netsetup.log  

->也可以查看linux 端samba 的日志信息： #cd /var/log/samba/

#tail –f 机器名.log

 

 

 

  

5) 加入域确认

 

 

 

 

6）.选目前不添加用户

 

 

 

7）完成并重启

 

 

 

8）重启生效

 

 

 

9）登入域
