      The <application>Samba</application> package provides file and print
      services to SMB/CIFS clients and Windows networking to Linux clients.
      <application>Samba</application> can also be configured as a Windows

      of a Windows Active Directory domain and a NetBIOS (rfc1001/1002)

      To test the results, issue:

      <filename class="directory">./st/summary</filename>.

    <!--
      If doing a security update or a new minor version (point releases do not
      apply here), run 'make testenv' before running 'make test' and 'make
      subunit-test'. This will set up the test environment and make the tests
      run faster, as well as point out any glaring issues that might affect
      the new Samba installation. With 4.10.4, I got 236 failures, 73 errors,
      and 2 unexpected successes. These were all known upstream, and you can
      find them in the knownfail list in their git repo. This is per
      Upstream's recommendation over IRC.

      <para>
        Additionally, developer test suites are available. If you've installed
        the optional python modules above in the Python virtual environment
        for building this package, you can run these tests with
        <command>make test</command>. It is not recommended for the average
        builder at around 290 SBU and over a gigabyte of disk space, and you
        should expect ~73 errors and ~30 failures from the 3000+ tests.

        Due to the complexity and the many various uses for

        section provides instructions to configure the
        <filename>/etc/samba/smb.conf</filename> file for two common scenarios.
        The complete contents of <filename>/etc/samba/smb.conf</filename> will
        depend on the purpose of <application>Samba</application>
        installation.

          You may find it easier to copy the configuration parameters shown

          instead of copying and editing the default file as mentioned in the
          <quote>Command Explanations</quote> section. How you create/edit the
          <filename>/etc/samba/smb.conf</filename> file will be left up to

        <title>Scenario 1: Minimal Standalone Client-Only Installation</title>

          Choose this variant if you only want to transfer files using

          Windows machines.

        <para>
          A <filename>/etc/samba/smb.conf</filename> file with the following
          three parameters is sufficient:
        </para>

<screen role='root'><literal>[global]
    workgroup = <replaceable>WORKGROUP</replaceable>
    dos charset = <replaceable>cp850</replaceable>
    unix charset = <replaceable>ISO-8859-1</replaceable></literal></screen>

        <para>
          The values in this example specify that the computer belongs to a
          Windows workgroup named
          <quote><replaceable>WORKGROUP</replaceable></quote>, uses the
          <quote><replaceable>cp850</replaceable></quote> character set on the
          wire when talking to MS-DOS and MS Windows 9x, and that the filenames
          are stored in the <quote><replaceable>ISO-8859-1</replaceable></quote>
          encoding on the disk. Adjust these values appropriately for your
          installation. The <quote>unix charset</quote> value must be the same
          as the output of <command>locale charmap</command> when executed with
          the <envar>LANG</envar> variable set to your preferred locale,
          otherwise the <command>ls</command> command may not display correct
          filenames of downloaded files.
        </para>

        <para>
          There is no need to run any <application>Samba</application>

        <title>Scenario 2: Standalone File/Print Server</title>

          described in Scenario 1.
        </para>

        <para>
          In this case, the <filename>/etc/samba/smb.conf.default</filename>
          file may be a good template to start from. Also, you should add the
          <quote>dos charset</quote> and <quote>unix charset</quote> parameters
          to the <quote>[global]</quote> section as described in Scenario 1 in
          order to prevent filename corruption. For security reasons, you may
          wish to define
          <replaceable>path = /home/alice/shared-files</replaceable>,

        <para>
          More complex scenarios involving domain control or membership are
          possible. Such setups are advanced topics and cannot be adequately
          covered in BLFS. Many complete books have been written on these topics
          alone. Note that in some domain membership scenarios, the
          <command>winbindd</command> daemon and the corresponding
          <phrase revision="sysv">bootscript</phrase>
          <phrase revision="systemd">systemd unit</phrase> are needed.

        <note>
          <para>
            This package comes with two types of units: A service file and a
            socket file. The service file will start the smbd daemon once at
            boot and it will keep running until the system shuts down. The
            socket file will make systemd listen on the smbd port (Default 445,
            needs to be edited for anything else) and will start the smbd
            daemon when something tries to connect to that port and stop the
            daemon when the connection is terminated. This is called socket
            activation and is analogous to using
            <application>{,x}inetd</application> on a SysVinit based system.
          </para>

          <para>
            By default, the first method is used - the smbd daemon is started
            at boot and stopped at shutdown. If the socket method is desired,
            you need to run the following commands as the <systemitem
            class="username">root</systemitem> user:
          </para>

<screen role="root"><userinput>systemctl stop smbd &amp;&amp;
systemctl disable smbd &amp;&amp;
systemctl enable smbd.socket &amp;&amp;
systemctl start smbd.socket</userinput></screen>

          <para>
            Note that only the smbd daemon can be socket activated.
