Here is a simple (but powerful) install script for a parental control featureIt is based on tinyproxy + firehol + dansguardian.Download the attached archive, extract it and run the script (2x click or from a terminal) (There are a couple of hidden files and folder too in the archive)It will d/l, install and configure all you need + install a GUI created by me to configure everything (it is located under System --> Administration)
