Samba

可以連接到 Samba,但不能訪問任何文件

  • January 1, 2016

我已經在我的 Centos 6.5 上成功安裝了 samba。我也創建了 samba 使用者。在 Windows 7 客戶端中,我可以連接到 samba 並且可以查看文件,但是當我嘗試打開它時,它說我無法訪問它。這是我的 samba.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
#
# For a step to step guide on installing, configuring and using samba, 
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the 
# Samba-Guide which is generated daily and can be downloaded from: 
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# 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. 
#
#---------------
# SELINUX NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba_share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

#======================= Global Settings =====================================

[global]

# ----------------------- Network Related Options -------------------------
#
# workgroup = NT-Domain-Name or Workgroup-Name, eg: MIDEARTH
#
# server string is the equivalent of the NT Description field
#
# netbios name can be used to specify a server name not tied to the hostname
#
# Interfaces lets you configure Samba to use multiple interfaces
# If you have multiple network interfaces then you can list the ones
# you want to listen on (never omit localhost)
#
# Hosts Allow/Hosts Deny lets you restrict who can connect, and you can
# specifiy it as a per share option as well
#
   workgroup = WORKGROUP
   server string = Samba Server Version %v

   netbios name = server

;   interfaces = lo eth0 192.168.12.2/24 192.168.13.2/24 
;   hosts allow = 127. 192.168.12. 192.168.13.

# --------------------------- Logging Options -----------------------------
#
# Log File let you specify where to put logs and how to split them up.
#
# Max Log Size let you specify the max size log files should reach

   # logs split per machine
   log file = /var/log/samba/log.%m
   # max 50KB per log file, then rotate
   max log size = 50

# ----------------------- Standalone Server Options ------------------------
#
# Scurity can be set to user, share(deprecated) or server(deprecated)
#
# Backend to store user information in. New installations should 
# use either tdbsam or ldapsam. smbpasswd is available for backwards 
# compatibility. tdbsam requires no further configuration.

   security = user
   passdb backend = tdbsam


# ----------------------- Domain Members Options ------------------------
#
# Security must be set to domain or ads
#
# Use the realm option only with security = ads
# Specifies the Active Directory realm the host is part of
#
# Backend to store user information in. New installations should 
# use either tdbsam or ldapsam. smbpasswd is available for backwards 
# compatibility. tdbsam requires no further configuration.
#
# Use password server option only with security = server or if you can't
# use the DNS to locate Domain Controllers
# 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 = *


;   security = domain
;   passdb backend = tdbsam
;   realm = MY_REALM

;   password server = <NT-Server-Name>

# ----------------------- Domain Controller Options ------------------------
#
# Security must be set to user for domain controllers
#
# Backend to store user information in. New installations should 
# use either tdbsam or ldapsam. smbpasswd is available for backwards 
# compatibility. tdbsam requires no further configuration.
#
# 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 Logons let Samba be a domain logon server for Windows workstations. 
#
# Logon Scrpit let yuou specify a script to be run at login time on the client
# You need to provide it in a share called NETLOGON
#
# Logon Path let you specify where user profiles are stored (UNC path)
#
# Various scripts can be used on a domain controller or stand-alone
# machine to add or delete corresponding unix accounts
#
;   security = user
;   passdb backend = tdbsam

;   domain master = yes 
;   domain logons = yes

   # the login script name depends on the machine name
;   logon script = %m.bat
   # the login script name depends on the unix user used
;   logon script = %u.bat
;   logon path = \\%L\Profiles\%u
   # disables profiles support by specifing an empty path
;   logon path =          

;   add user script = /usr/sbin/useradd "%u" -n -g users
;   add group script = /usr/sbin/groupadd "%g"
;   add machine script = /usr/sbin/useradd -n -c "Workstation (%u)" -M -d /nohome -s /bin/false "%u"
;   delete user script = /usr/sbin/userdel "%u"
;   delete user from group script = /usr/sbin/userdel "%u" "%g"
;   delete group script = /usr/sbin/groupdel "%g"


# ----------------------- 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
#
# OS Level determines the precedence of this server in master browser
# elections. The default value should be reasonable
#
# Preferred Master causes Samba to force a local browser election on startup
# and gives it a slightly higher chance of winning the election
;   local master = no
;   os level = 33
;   preferred master = yes

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both
#
# - WINS Support: Tells the NMBD component of Samba to enable it's WINS Server
#
# - WINS Server: Tells the NMBD components of Samba to be a WINS Client
#
# - 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.
#
# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups.

;   wins support = yes
;   wins server = w.x.y.z
;   wins proxy = yes

;   dns proxy = yes

# --------------------------- Printing Options -----------------------------
#
# Load Printers let you load automatically the list of printers rather
# than setting them up individually
#
# Cups Options let you pass the cups libs custom options, setting it to raw
# for example will let you use drivers on your Windows clients
#
# Printcap Name let you specify an alternative printcap file
#
# You can choose a non default printing system using the Printing option

   load printers = yes
   cups options = raw

;   printcap name = /etc/printcap
   #obtain list of printers automatically on SystemV
;   printcap name = lpstat
;   printing = cups

# --------------------------- Filesystem Options ---------------------------
#
# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.
#
# Note: these options can also be set just per share, setting them in global
# makes them the default for all shares

;   map archive = no
;   map hidden = no
;   map read only = no
;   map system = no
;   store dos attributes = yes


#============================ Share Definitions ==============================

[homes]
   comment = Home Directories
   browseable = yes
   writable = yes
   valid users = Mohamed Moussa
   public = yes
;   valid users = MYDOMAIN\%S

[iam] 
   comment = Partage De fichier Contable
   browseable = yes
   writable = yes
   guest ok = yes
   path = /ITFiles
   valid users = Mohamed Moussa
   public = yes 

[printers]
   comment = All Printers
   path = /var/spool/samba
   browseable = no
   guest ok = no
   writable = no
   printable = yes

# Un-comment the following and create the netlogon directory for Domain Logons
;   [netlogon]
;   comment = Network Logon Service
;   path = /var/lib/samba/netlogon
;   guest ok = yes
;   writable = no
;   share modes = no


# Un-comment the following to provide a specific roving profile share
# the default is to use the user's home directory
;   [Profiles]
;   path = /var/lib/samba/profiles
;   browseable = no
;   guest ok = yes


# A publicly accessible directory, but read only, except for people in
# the "staff" group
;   [public]
;   comment = Public Stuff
;   path = /home/samba
;   public = yes
;   writable = yes
;   printable = no
;   write list = +staff

這可能是由於 SELINUX。為了快速修復,請嘗試通過執行該命令將 SELINUX 置於許可(即:非阻塞)模式:

setenforce 0

/etc/selinux/config如果可行,您可以考慮通過編輯文件將 SELINUX 永久置於許可模式

無論如何,這是不推薦的,因為 SELINUX 是一個有價值的安全子系統。讓 SELINUX 與 Samba 結合的規範方法是使用正確的安全標記/上下文標記您正在共享的目錄。例如,關於您[iam]的分享,您應該發出以下命令:

semanage fcontext -a -t samba_share_t "/ITFiles(/.*)?"
restorecon -RF /ITFiles

另一種可能性是使用 SELINUX 布爾值將所有samba_export_all_rw文件系統目錄設置為啟用 Samba 。例如,發出命令:

setsebool -P samba_export_all_rw on

將啟用對所有文件系統目錄的讀/寫訪問。雖然不安全,但這總比完全禁用 SELINUX 要好。
