LINUX之Samba学习之道

1.smb.conf说明
---------------------------------------------------------------------
# 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]                                    说明整体环境
# workgroup = NT-Domain-Name or Workgroup-Name
workgroup = workgroup  设置工作组名称,该名称会出现在Windows的网上     邻居和Linux的网络服务器中
netbios name= aaa   设置netbios bios名称
# server string is the equivalent of the NT Description field
server string = Samba Server  服务器说明
# 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. 127.  它严格限制了可访问Samba Server的IP范围，默认是允许所有，去掉；就可启用
# if you want to automatically load your printer list rather
# than setting them up individually then you'll need this
printcap name = /etc/printcap  打印机配置文件路径
load printers = yes    是否将打印机共享
# 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    打印机的类型
# Uncomment this if you want a guest account, you must add this to /etc/passwd
# otherwise the user "nobody" is used
#  guest account =pcguest     如果想让用户“pcguest”匿名访问去掉#，并确保在/etc/passwd中有此用户。
# this tells Samba to use a separate log file for each machine
# that connects
log file = /var/log/samba/%m.log  log会在此目录中为每个登录samba的用户建立不同的日志文件
# Put a capping on the size of the log files (in Kb).
max log size = 0    定义log文件的大小
# Security mode. Most people will want user level security. See
# security_level.txt for details.
security = share    安全级别，分为4种：share,user,server,domain
# 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     密码级别设置
;  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   用户密码要加密
smb passwd file = /etc/samba/smbpasswd 将密码服务器设置为Samba Server时，需要用此行来指定要验证的密码文件，若设置为window NT server，则不需要这行。这里最重要的是密码文件设置的路径
# 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   当用户要求更改密码时，使用PAM，不用本地口令程序/user/bin/passwd
# Unix users can map to different SMB User names
;  username map = /etc/samba/smbusers   在此文件中设置对应的用户
# 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   当用户认证时，服从PAM的管理限制
# Most people will find that this option gives better performance.
# See speed.txt and the manual pages for details

# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
;   os level = 33
# 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
# if you enable domain logons then you may want a per-machine or

;   wins server = w.x.y.z    WINS客户端设置
# WINS Proxy - Tells Samba to answer name resolution queries on

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

2.配置Samba服务器
  ■2.1 配置share级服务器
       workgroup = linux
       netbois name = aaa
       printcap name = /etc/printcap
       load printers = yes
       printing = lprng
       guest account = pcguest

       log file = /var/log/samba/%m.log
       max log size = 50
       security = share
       socket options = TCP_NODELAY SO_RCVBUF=8129 SO_SNDBUF=9129
      [homes]     
comment = Home Directories   
browseable = yes   
writeable = yes   
valid users = %S
create mode = 0664
directory mode = 0775
      [printers]
             comment = All Printers   
path = /var/spool/samba   
browseable = no   
printer name = printer
public = yes
       [ftp]
comment = ftp share   
path = /var/ftp   
public = yes
  ■2.2 配置user级服务器
      
       在share级的基础上修改：
          security = share
          改为security = user
          添加guest accout = pcguest
                 encrypt passwords = yes
                 smb passwd file = /etc/samba/smbpasswd
        当对配置文件/etc/smb.conf进行user级的设置后，需要设置samba密码文件，建立smbpasswd账号和口令，使其与/etc/passwd的账号和口令相同。方法如下：
          (1) 建立本地账号，生成口令文件/etc/passwd，把/etc/passwd里的用户都加到/etc/samba/smbpasswd文件中。注意，该过程是先在本地建立账号及账号的密码，然后再把
               口令文件传给/etc/samba/smbpasswd，顺序不能反，即本地账号的口令和samba服务器中账号是不相同的。
               #adduser pcguest
   #passwd pcguest
   #cat /etc/passwd|mksmbpasswd.sh>/etc/samba/smbpasswd
          (2) 利用smbpasswd命令来为刚才建立的账号设立samba server口令。注意，使用smbpasswd命令修改用户口令时，被修改的samba账号的本地系统用户账号必须已经存在。
   #smbpasswd pcguest
          (3) 重新启支samba server
               # /etc/init.d/smb restart
  ■2.3 配置domain级服务器
      
       只需在user级配置的基础上修改：
            security = user
            workgroup = linux
       为:
            security = domain
            workgroup = wenda    　∥wenda是主域控制器域名
       添加：
            netbios = linux
            password server = wendaserver    ∥用windows 2000主域控制器wendaserver来做密码服务器
       注释掉：
            smb passwd file = /etc/samba/smbpasswd
