Serveur Samba: sécurité = utilisateur ne s'affiche pas

Question

J'essaie d'utiliser Ubuntu Server pour configurer un serveur Samba. Cependant, dans toutes les instructions que je vois, il est dit de décommenter la ligne security = user. Je ne vois pas cette ligne où il est censé être. Devrais-je simplement l'ajouter? Quelle est exactement sa signification?

Voici mon /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 =======================

  # create dirs. with group=rw permissions, set next parameter to 0775.
  ;   directory mask = 0700

  # By default, \\server\username shares can be connected to by anyone
  # with access to the samba server.
  # Un-comment the following parameter to make sure that only "username"
  # can connect to \\server\username
  # This might need tweaking when using external authentication schemes

  ;   read only = yes

  # Un-comment the following and create the profiles directory to store
  # users profiles (see the "logon path" option above)

  ;   write list = root, @lpadmin

Answer 1

oui, ajoutez ceci dans la section global

[global]
security = user

Le mode de sécurité par défaut avec Samba est user-level sécurité. Avec cette méthode, chaque partage se voit attribuer des utilisateurs spécifiques qui peuvent y accéder. Lorsqu'un utilisateur demande une connexion à un partage, Samba s'authentifie en validant les données username et password fournies avec les utilisateurs autorisés dans le fichier de configuration et les mots de passe dans la base de données de mots de passe du serveur Samba. pour plus d'informations tilisateurs samba et sécurité .

il existe plusieurs méthodes de sécurité Server-Level, Domain-Level, Share-Level etc., donc user-level est la valeur par défaut. juste permettre à l'utilisateur comme:

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

et n'oubliez pas d'ajouter un mot de passe à chaque utilisateur de samba à l'aide de la commande suivante:

Sudo smbpasswd -a your_user

vous pouvez obtenir de l'aide d'une autre question Ubuntu Comment puis-je configurer les partages Samba pour que seuls certains utilisateurs puissent y accéder?

Answer 2

Oui, vous pouvez l'ajouter là où il devrait être. Ce sera sous la balise [global]. Assurez-vous également de configurer les utilisateurs de samba dans cette section:

[(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

Les mots de passe doivent être configurés avec Sudo smbpasswd -a. Plus d'informations sur cette commande peuvent être trouvées en exécutant man smbpasswd.

Answer 3

Vous avez commis certaines erreurs en rendant samba stable le serveur, il n'y a pas de protocole IP et C++ connectés les uns aux autres. JavaScript ne répond pas à DHCP, il ne répond même pas aux commandes PING de CMD HELP et Python. Un autre problème est que Switch et Router ont le même IPv6 et que VLAN1 se trouve en dehors de la frontière 192.168.2.100. RJ45 n'est pas branché sur WALL et la page JK015.cba.pl n'est pas dans le même réseau.
