Installing Creative Labs WebCam 3 on Debian 'sarge' GNU/Linux with camserv

I did reinstall the setup on a sarge box and here are the details:

# echo "options ov511 force_palette=15" > /etc/modprobe.d/ov511
# mknod /dev/video0 c 81 0
# chown nobody:video /dev/video0
# chmod 640 /dev/video0
# ln -s /dev/video0 /dev/video

Plug the cam into your usb port!

# aptitude install camserv

You can modify /etc/camserv/camserv.cfg for your needs. Have fun!
