Logging websites visited?

Hi,

I have been asked to log all websites people go onto.

I've been trying to setup squid in Ubuntu to do this but havnt got anywhere in days.

Does anyone know of a piece of software that logs centrally on the server every site people go onto including their username?

Many thanks,

Dan.

I think ClearOS and Zeroshell have these features and they are premade, fine as long as you are not using Hyper-V
