Filter and monitor web access on Linux transparently

I have put together a howto document to describe how the internet access on a linux computer can be filtered, and daily/weekly/monthly email reports can be sent for monitoring purposes. This was meant as a replacement for the program “Safe Eyes” as it would not run on Linux.

PDF howto (6 pages)

There are some links to this item on different Ubuntu Wiki pages and even a German translation of the howto on this blog entry (thanks to David Rekowski).
