    <title>Installation of vsftpd</title>

    <para>For security reasons, running <application>vsftpd</application>
    as an unprivileged user and group is encouraged. Also, a user should be
    created to map anonymous users. As the <systemitem
    class="username">root</systemitem> user, create the needed directories,
    users, and groups with the following commands:</para>

<screen role="root"><userinput>install -v -d -m 0755 /var/ftp/empty &amp;&amp;
install -v -d -m 0755 /home/ftp &amp;&amp;
groupadd -g 47 vsftpd &amp;&amp;
useradd -d /dev/null -c "vsftpd User" -g vsftpd -s /bin/false \
        -u 47 vsftpd &amp;&amp;
groupadd -g 45 ftp &amp;&amp;
useradd -c anonymous_user -d /home/ftp -g ftp -s /bin/false -u 45 ftp</userinput></screen>

    <para>Build <application>vsftpd</application> as an unprivileged user
    using the following command:</para>

<screen><userinput>make</userinput></screen>

    <para>Once again, become the <systemitem class="username">root</systemitem>
    user and install <application>vsftpd</application> with the following
    commands:</para>

<screen><userinput>install -v -m 755 vsftpd /usr/sbin/vsftpd &amp;&amp;
install -v -m 644 vsftpd.8 /usr/share/man/man8 &amp;&amp;

  <sect2 role="commands">
    <title>Command Explanations</title>

    <para><command>install -v -d ...</command>: This creates the
    directory that anonymous users will use (<filename
    class='directory'>/home/ftp</filename>)
    and the directory the daemon will chroot into
    (<filename class='directory'>/var/ftp/empty</filename>).</para>

    <note>
      <para><filename class="directory">/home/ftp</filename> should not be
      owned by the user <systemitem class="username">vsftpd</systemitem>,
      or the user <systemitem class="username">ftp</systemitem>.</para>
    </note>

    <para><command>echo "#define VSF_BUILD_TCPWRAPPERS" >>builddefs.h</command>:
    Use this prior to <command>make</command> to add support for
    <application>tcpwrappers</application>.</para>

    <para><command>echo "#define VSF_BUILD_SSL" >>builddefs.h</command>:
    Use this prior to <command>make</command> to add support for SSL.</para>

    <para><command>install -v -m ...</command>:
    The <filename>Makefile</filename> uses non-standard installation paths.
    These commands install the files in
    <filename class='directory'>/usr</filename> and
    <filename class='directory'>/etc</filename>.</para>

      <title>Configuration Information</title>

      <para><application>vsftpd</application> comes with a basic
      anonymous-only configuration file that was copied to
      <filename class='directory'>/etc</filename> above. While still as
      <systemitem class="username">root</systemitem>, this file should be
      modified because it is now recommended to run <command>vsftpd</command>
      in standalone mode as opposed to
      <command>inetd</command>/<command>xinetd</command> mode. Also, you
      should specify the privilege separation user created above. Finally,
      you should specify the <command>chroot</command> directory.
      <command>man vsftpd.conf</command> will give you all the details.</para>

<screen role="root"><userinput>cat &gt;&gt; /etc/vsftpd.conf &lt;&lt; "EOF"
