Re: Child proofing a laptop
Yea I really liked K9 when I put it on someone's pc before. It's very easy to configure and you just need to select which groups of websites you want to allow.
Opendns would be good for trying to just block large ranges, but I bet you could still find proxies to get by using a method like that. If you know the IP address of a proxy server all you would have to do is type it in and you'd be thwarted.
