    <title>Installation of ProFTPD</title>

    <para>For security reasons, you should install
    <application>ProFTPD</application> using an unprivileged user and group.
    As the <systemitem class="username">root</systemitem> user:</para>

<screen role="root"><userinput>groupadd -g 46 proftpd &amp;&amp;

ln -v -s /bin/false /usr/bin/proftpdshell &amp;&amp;
echo /usr/bin/proftpdshell &gt;&gt; /etc/shells</userinput></screen>

    <para>Install <application>ProFTPD</application> as an unprivileged user by
    running the following commands:</para>

<screen><userinput>./configure --prefix=/usr --sysconfdir=/etc \
    --localstatedir=/var/run &amp;&amp;

    <title>Command Explanations</title>

    <para><command>install -v -d -m775 -o proftpd -g proftpd
    /srv/ftp</command>: Create the home directory for
    <application>ProFTPD</application>.</para>

    <para><command>ln -v -s /bin/false /usr/bin/proftpdshell</command>:
    Set the default shell as a link to an invalid shell.</para>

    <para><command>echo /usr/bin/proftpdshell &gt;&gt;
    /etc/shells</command>: Fake a valid shell for compatibility purposes.</para>

    <note>
      <para>The above two commands can be omitted if the following directive is
      placed in the configuration file:</para>

<screen><literal>RequireValidShell off</literal></screen>

      <para>By default, proftpd will require that users logging in have valid
      shells. The RequireValidShell directive turns off this requirement. This
      is only recommended if you are setting up your FTP server exclusively
      for anonymous downloads.</para>
    </note>

    <para><parameter>--sysconfdir=/etc</parameter>: This prevents the
    configuration files from going to
    <filename class="directory">/usr/etc</filename>.</para>

    <para><parameter>--localstatedir=/var/run</parameter>:
    This uses <filename class="directory">/var/run</filename> instead of
    <filename class="directory">/usr/var</filename> for lock files.</para>
