Lighttpd Changes
lighttpd.conf
light.tar.gz
Need to copy this lighttpd.conf and light.tar.gz files in RPI camera target
lighttpd.conf:
Need to copy this lighttpd.conf file into /etc/lighttpd
light.tar.gz:
copy this into camera target
Local system : scp light.tar.gz root@camera_ip:/
camera target:
cd /
tar -xzvf light.tar.gz
While untar this light.tar.gz file the respective files will automatically copy to usr/bin , usr/lib , usr/share directory.
Once did above steps then reboot the target.
