Hi all, I work for a small company and we are very strapped for cash right now as I'm sure a lot of people are. My boss has noticed several people while walking by with their facebook/myspace/whatever open rather than working. He has tasked me with finding a free way of blocking all access to the internet except for approved "whitelist" websites.
I've searched and found a way of doing it using the built in "Internet Content Adviser" by using a filter that blocks out everything, then allowing sites. It works, but not very cleanly. Its a per workstation thing and requires manually editing each workstation. It also breaks IE for every user that logs into the restricted PC, not just a single specific user.
Does anyone know of anything free out there that I can use as a "block all/allow specific" web filter based on user? I've never set up anything like this so something with instructions or a nice GUI would be nice. I have almost zero Linux experience but would be willing to try to learn enough to get something like this up and going if it wasn't extremely difficult.
If there's really not anything out there I'll probably just end up using the built in IE Internet Content Adviser but wondered if there was a better, more elegant way of doing it.
