Samba (サンバ) は、マイクロソフトのWindowsネットワークを実装したフリーソフトウェア。
Linux、Solaris、BSD、Mac OS XなどのUnix系OS を用いて、Windows のファイルサーバやプリントサービス、ドメインコントローラ機能、ドメイン参加機能を提供する。
SambaとWindows
- Windows Server 2003とSambaの大きな違いはActiveDirectoryの部分であるが、ActiveDirectoryはユーザ情報をLDAPに格納し、
認証ではケロベロス認証(チケット方式)を使う。 - Sambaはユーザ情報をLDAPに格納し、認証ではNTLM認証(チャレンジレスポンス方式)を使う。
Samba構築手順
下記では/home/public/sambaを共有ディレクトリとし、shareという共有名を作成する。
似たような手順になるが、UbuntuとCentOSについて記述する。
Ubuntuの場合
- sudo apt-get install samba インストール
- sudo mkdir /home/public/samba 共有ディレクトリ
- sudo chown nobody:nogroup /home/public/samba オーナー設定
- sudo chmod 777 /home/public/samba アクセス権設定
- sudo vi /etc/samba/smb.conf 設定ファイル更新
# # 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 # errors. # #======================= Global Settings =======================

# server string is the equivalent of the NT Description field server string = %h server (Samba, Ubuntu)
# 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. dns proxy = no
# What naming service and in what order should we use to resolve host names # to IP addresses ; name resolve order = lmhosts host wins bcast
#### Networking ####
# 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 = 127.0.0.0/8 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
#### Debugging/Accounting ####
# This tells Samba to use a separate log file for each machine # that connects log file = /var/log/samba/log.%m
# Put a capping on the size of the log files (in Kb). max log size = 1000
# 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.
syslog = 0
# Do something sensible when Samba crashes: mail the admin a backtrace panic action = /usr/share/samba/panic-action %d
####### Authentication #######
# “security = user” is always a good idea. This will require a Unix account # in this server for every user accessing the server. See # /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html # 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. encrypt passwords = true
# If you are using encrypted passwords, Samba will need to know what # password database type you are using. passdb backend = tdbsam
obey pam restrictions = yes
; guest account = nobody invalid users = root
# 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. ; unix password sync = no
# 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). passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully* .
# 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’. ; pam password change = no
########## 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
# When using [print$], root is implicitly a ‘printer admin’, but you can # also give this right to other users to add drivers and set printer # properties ; printer admin = @lpadmin
############ 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: # SO_RCVBUF=8192 SO_SNDBUF=8192 socket options = TCP_NODELAY
# 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

Samba の再起動と動作確認
Samba を再起動して設定の変更を有効にします。
$ sudo /etc/init.d/samba restart * Stopping Samba daemons… [ OK ] * Starting Samba daemons… [ OK ]
CentOSの場合
導入
- su (rootで作業を行うか sudo コマンドを使用するかはお任せします)
- yum -y install samba
- rpm -qa | grep samba
(rpm -qa samba) - /etc/rc.d/init.d/smb start
もしくは・・・
# service smb start
- smbプロセスとnmbdのプロセスを確認
# ps aux | grep smb # ps aux | grep nmbd
sambaの自動起動設定
chkconfig smb on
- 自動起動設定の確認
chkconfig -- list smb smb 0:off 1:off 2:on 3:on 4:on 5:on 6:off
UbuntuとCentOSの差 (主にSambaにおいて)
- アプリケーションの導入手順
- Ubuntu sudo apt-get install samba
- CentOS sudo yum -y install samba
- サービスの起動
- Ubuntu /etc/init.d/samba start
- CentOS service smb start
- 共有ディレクトリの設定
- Ubuntu sudo chown nobody:nogroup /var/samba
- CentOS sudo chown nobody:nobody /var/samba
- サービスの自動起動
- CentOS chkconfig smb on
今後のMP-Factory5.0向け設定
- Linux側の実ディレクトリは「/home/public/samba」とする
