2. Reboot
3. Delete fun_plug.tgz from Volume1 if still present

********************************************************
4. Install IPKG:
********************************************************
mkdir -p /opt
mkdir -p /mnt/HD_a2/ipkg/opt
mount -o bind /mnt/HD_a2/ipkg/opt /opt
export PATH=/opt/bin:/opt/sbin:$PATH

ipkg_name=`wget -qO- $feed/Packages | awk '/^Filename: ipkg-opt/ {print $2}'`
wget $feed/$ipkg_name
zcat $ipkg_name | tar -xOvf - ./data.tar.gz | zcat | tar -C / -xvf -
echo src dns323 http://ipkg.nslu2-linux.org/feeds/optware/dns323/cross/unstable >> /opt/etc/ipkg.conf
ipkg update

********************************************************
5. Install SANE & HPLIB
********************************************************
cd /opt
ipkg install sane-backends
ipkg install libieee1284
ipkg install hplip # Default choice for dll.conf => Y overwrite current version
ipkg install cups
ipkg install dbus

mkdir /opt/bin/data/models
ln -s /opt/share/hplip/data/models/models.dat /opt/bin/data/models
ln -s /opt/share/hplip/hpssd.py /opt/bin

chmod a+x /ffp/start/inetd.sh
chmod a+x /ffp/start/sane.sh

edit the /opt/etc/sane.d/saned.conf to include your network range or ip-addresses where you want to scan from
vi /opt/etc/sane.d/saned.conf

Edit /ffp/etc/rc and add :/opt/bin:/opt/sbin to the PATH export
vi /ffp/etc/rc

reboot
