使用 Samba 進行
Windows型態的檔案及列印服務
Linux可以使用 Samba 套件提供 SMB 服務 (例如. WfW, Win95，及 NT型態的網路檔案及列印分享)。
這一節會描述如何組態分享，以及如何從客戶端存取這些服務。
Samba 套件包含在 Red Hat 發行版中，您可以檢查是否安裝以及其版本，鍵入:
rpm -q samba
如果尚未安裝，您需要使用 RPM 公用程式安裝它。 查看 第10章，使用 Red Hat 套件管理程式 (RPM)
一節 有關如何做的細節。
這些 Samba 檔中您應該關心的最重要部分是:
/etc/smb.conf
Samba 組態檔是分享及其他組態參數的設定 (查看下面)
/var/log/samba/
放 Samba log 檔的地方
/home/samba/
建議應該設定的檔案分享位置。 然而， 您應該選擇一個符合足夠您存放檔案空間的地方。個人來說，
我常設定一個大的 partition 掛載在 /archive/ 下並且放我的分享檔案。
``/etc/smb.conf' 檔包含了檔案及列印分享的組態資訊。檔案的開頭幾行包含了整體的組態方針，所
有的分享都相同 (除非他們超越了每一個獨立分享的基礎)，其馀的是分享部分。
Samba 安裝包括了一個預設的 smb.conf 檔，可以滿足您大多數的
需求，且只需作稍微的修改。
這是這個檔的 一些例 (我會大幅地自訂它給您看看更多重要及有趣的部分):
# Items common to all shares (unless over-ridden on a per-share basis)
[global]
# Number of minutes of inactivity before client is disconnected
# to avoid consuming resources. Most clients will automatically
# reconnect so this is a good idea to enable.
dead time = 10
# Don't let users connect as “root”, just-in-case. :-)
invalid users = root
# Specify the a
clearcase/" target="_blank" >ccount for guest shares (shares that don't require
# a password to connect to. This username must be a valid user
# in the /etc/passwd file.
guest account = guest
# Specify where log files should be written to. The “%m” suffix
# means that log files will be created in the format
# log.machine-name (eg. “log.twixel”)
log file = /usr/local/samba/logs/log.%m
# Maximum size of log file, in Kilobytes.
max log size = 1000
# Password level 3 means that case is not an issue when entering
# passwords. A little less secure than level 1 or 2 would be,
# but seems to be a fair compromise for user convenience.
password level = 3
# Specify that all shares should appear in the browse list
# (override any you don't w
ant on a per-share basis).
browseable = yes
# If this is enabled, you can see active connections using the
# “smbstatus” command.
status = yes
# The level of de
bugging information that is recorded in the log
# files. Higher values generate more information (which is
# probably not very useful, most of the time).
debug level = 2
# This will send any Windows-style “POPUP” messages received on
# the server to the postmaster by e-mail. Not very useful, but
# an interesting demonstration of what can be accomplished.
message command = /bin/mail -s 'Message from %f on %m' postmaster < %s; rm %s &
# This is a form of caching that, when enabled, may improve
# performance when reading files.
read prediction = true
# A list of services that should be added automatically to the
# browse-list.
auto services = cdrom
# The location of your “printcap” file, a text file containing
# definitions for your printers.
printcap name = /etc/printcap
# If enabled all printers in the /etc/printcap file will be
# loaded into the browse-list.
load printers = yes
# The print command by which data is spooled to a printer under Linux.
print command = lpr -r -P%p %s
# The print command by which job queue information (printer status)
# can be obtained.
lpq command = lpq -P%p
# The print command by which unwanted print jobs can be deleted
# from the queue.
lprm command = lprm -P%p %j
# The level at which Samba advertises itself for browse elections.
# Currently set to a high value to give it an even “foot-hold” with
# any swarmy NT servers on the
.network. :-)
os level = 34
# These are user's personal shares. If the client's username matches on the
# server, they can access their home directory (provided they enter the
# correct password).
[homes]
# The comments appear in the browse list.
comment = Home Directories
# This matches the username of the client to that of the share.
# If they do not match, no share will be displayed in the browse
# list, or available to connect to.
user = %S
# The path to the share. For example, “smithj” would map to
# “/home/smithj”
path = /home/%S
# If enabled, allow read/write access to the shares.
writeable = yes
# Just an inverted synonym for “writeable”. We don't *really* need
# to use both. :-)
read only = no
# Keep this disabled so that a password is required to access these
# shares.
public = no
# We don't want this share (after all, it is private) to appear in
# the browse-list of other users.
browseable = no
# This is a publicly available print share, called “hp_laser”. It appears
# on the browse lists and can be accessed without a password by any client.
[hp_laser]
# The comment that appears in the browse-list.
comment = Main office printer (HP Laserjet 400)
# The username that this share is accessed as (guest means all users).
user = guest
# All generated print files will first be created in the /tmp
# directory.
path = /tmp
# Do not allow file creation except through print spooling.
writeable = no
# Set permissions accordingly -- root access to print jobs only.
create mode = 0700
# If this is enabled a password is not required to access the share.
public = yes
# This should be enabled to indicate that this is a printer share.
printable = yes
# Here is a service providing access to the CD-ROM device.
[cdrom]
comment = Shared CD-ROM drive on Linux
user = guest
path = /cdrom
writeable = no
read only = true
browseable = yes
public = yes
guest ok = yes
小技巧: 最近的 Samba 版本， 從 2.0 以後，提供了一個非常靈活以網頁為基礎的組態公用程式叫做``swat'，
可以使得組態過程更為友善。這個公用程式傾聽伺服器上的 TCP port 901 ，所以要使用的話必須將您的浏覽器
指向下面的位址:
mydomain.name:901
(當然如果要使用 SWAT 的話您需要讓網頁伺服器執行，像是 Apache。 查看 第7章，網頁伺服器及 HTTP 快取代理
主機管理 一節 有關細節。)
最新版的 Samba 和 2.0 版之前的相比增加了很多功能。 升級到這個版本是值得的。
客戶端必須有 TCP/IP network stack 以連接分享。更進一步，為了浏覽工作，TCP/IP 協定必須 bound 到
NETBEUI。在 Windows 95 可以由控制台中的``網路'進行組態。
假設客端已經正常地組態好， 您應該可以看到伺服端的分享出現在“網路上的芳鄰” (或如果您不是使用
Windows 95/NT的相等的方案)。您可以從網路上的芳鄰對映到網路磁碟，或鍵入到分享的絕對路徑
(例如. “\\mail\cdrom”)。 如果分享服務需要鍵入密碼，您會被提示。
