    <title>Introduction to SANE</title>

    <para><application>SANE</application> is short for Scanner Access Now Easy.
    Scanner access, however, is far from easy, since every vendor has their own
    protocols. The only known protocol that should bring some unity into this
    chaos is the TWAIN interface, but this is too imprecise to allow a stable
    scanning framework. Therefore, <application>SANE</application> comes with
    its own protocol, and the vendor drivers can't be used.</para>

    <para><application>SANE</application> is split into back ends and front
    ends. The back ends are drivers for the supported scanners and cameras. The
    front ends are user interfaces to access the backends.</para>

    <para>To access your scanner, you will probably need the related kernel
    drivers and/or additional support packages. A SCSI scanner will need SCSI
    drivers, a parallel port scanner needs parallel port support (you should
    use enhanced EPP modes) and perhaps <ulink
    url="http://cyberelk.net/tim/libieee1284/">libieee1284</ulink> and a USB
    scanner will need the <xref linkend="libusb"/> package. Ensure you have
    the necessary drivers properly configured to access the devices.</para>

        <para>The <command>saned</command> daemon is not meant to be used for
        untrusted clients. You should provide <xref linkend="tcpwrappers"/>
        and/or <xref linkend="fw-firewall"/> protection to insure only trusted
        clients access the daemon. Due to the complex security requirements to
        insure only trusted clients access the daemon, BLFS does not provide
        instructions to configure the <command>saned</command> daemon. If you
        desire to make the daemon available, ensure you provide adequate
        security, configure your <filename>[x]inetd.conf</filename> file and
        send a <userinput>SIGHUP</userinput> to the [x]inetd daemon. Some good
        information for setting up and securing the <command>saned</command>
        daemon can be found at
