Samba 服务器:安全 = 用户未显示

Samba 服务器:安全 = 用户未显示

我正在尝试使用 Ubuntu Server 设置 Samba 服务器。但是,我看到的所有说明都要求取消注释该行security = user。我没有在应该出现的位置看到该行。我应该直接添加它吗?它到底有什么意义?

这是我的 /etc/samba/smb.conf

#
  # 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
  #
  # Some options that are often worth tuning have been included as
  # commented-out examples in this file.
  #  - When such options are commented with ";", the proposed setting
  #    differs from the default Samba behaviour
  #  - When commented with "#", the proposed setting is the default
  #    behaviour of Samba but the option is considered important
  #    enough to be mentioned here
  #
  # 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]

  ## Browsing/Identification ###

  # Change this to the workgroup/NT-domain name your Samba server will part of
     workgroup = SAMBA-SERVER

  # 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

  #### 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 = yes



  #### Debugging/Accounting ####

  # This tells Samba to use a separate log file for each machine
  # that connects
     log file = /var/log/samba/log.%m

  # Cap the size of the individual log files (in KiB).
     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 #######

  # Server role. Defines in which mode Samba will operate. Possible
  # values are "standalone server", "member server", "classic primary
  # domain controller", "classic backup domain controller", "active
  # directory domain controller". 
  #
  # Most people will want "standalone sever" or "member server".
  # Running as "active directory domain controller" will require first
  # running "samba-tool domain provision" to wipe databases and create a
  # new domain.
     server role = standalone server

  # 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

  # 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 = yes

  # For Unix password sync to work on a Debian GNU/Linux system, the following
  # parameters must be set (thanks to Ian Kahan <<[email protected]> for
  # sending the correct chat script for the passwd program in Debian Sarge).
     passwd program = /usr/bin/passwd %u
     passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\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 = yes

  # This option controls how unsuccessful authentication attempts are mapped
  # to anonymous connections
     map to guest = bad user

  ########## Domains ###########

  #
  # The following settings only takes effect if 'server role = primary
  # classic domain controller', 'server role = backup domain controller'
  # or '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
  # (this is Samba's default)
  #   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

  # This allows machine accounts to be created on the domain controller via the 
  # SAMR RPC pipe.  
  # The following assumes a "machines" group exists on the system
  ; add machine script  = /usr/sbin/useradd -g machines -c "%u machine account" -d /var/lib/samba -s /bin/false %u

  # This allows Unix groups to be created on the domain controller via the SAMR
  # RPC pipe.  
  ; add group script = /usr/sbin/addgroup --force-badname %g

  ############ 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

  # Some defaults for winbind (make sure you're not using the ranges
  # for something else.)
  ;   idmap uid = 10000-20000

  ;   template shell = /bin/bash

  # Setup usershare options to enable non-root users to share folders
  # with the net usershare command.

  # Maximum number of usershare. 0 (default) means that usershare is disabled.
  ;   usershare max shares = 100

  # Allow users who've been granted usershare privileges to create
  # public shares, not just authenticated ones
     usershare allow guests = yes

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

答案1

是的,在global部分中添加此内容

[global]
security = user

默认的安全模式Sambauser-levelsecurity。使用此方法,每个共享都分配有可以访问它的特定用户。当用户请求连接到共享时,Samba 会通过验证给定的usernamepassword配置文件中的授权用户以及 Samba 服务器密码数据库中的密码来进行身份验证。了解更多信息samba 用户和安全

有几种安全方法Server-Level,等等Domain-LevelShare-Level所以user-level是默认的。只允许用户像这样:

[yoursharename]
    writable = yes
    valid users = user1,user2,user3

并且不要忘记使用命令为 samba 中的每个用户添加密码:

sudo smbpasswd -a your_user

你可以从另一个 Ubuntu 问题中获取帮助如何设置 Samba 共享以仅供特定用户访问?

答案2

是的,您可以将其添加到应该添加的位置。它将位于[global]标签下方。此外,请确保在此部分中设置 Samba 用户:

[(yoursharename)]
    writable = yes # change to no if you don't want users to write to folder
    valid users = user1,user2,user3 # set up passwords later

需要使用 设置密码sudo smbpasswd -a。可以通过运行 找到有关该命令的更多信息man smbpasswd

答案3

您在使服务器稳定时犯了一些错误,samba没有 IP 协议和 C++ 相互连接。JavaScript 根本不响应 DHCP,它甚至不响应来自 CMD HELP 和 Python 的任何 PING 命令。另一个问题是交换机和路由器具有相同的 IPv6,并且 VLAN1 超出了 192.168.2.100 的边界。RJ45 未插入 WALL,页面 JK015.cba.pl 不在同一个 NET 中。
