How To Configure Real PC Parental Controls?
Orange Crush writes "As the resident computer geek in an office full of accountants, my boss recently asked me how she could reasonably keep her teenage son from using the family computer to 'access inappropriate sites.' I of course responded 'Give up now. There's nothing in this world that can keep a determined teenager from acquiring porn.' Sadly, she was dissatisfied with this answer. I mentioned that there was in fact software available for this purpose, but that all of it was trivially easy to bypass for a clever young mind. I really can't think of another answer. She could password protect the BIOS to prevent booting a different OS, but that's easily defeated with a screwdriver at most. The only solutions I can think of involve upstream firewalls/proxies/etc to which I gleefully redirected her to her ISPs tech support number. As much as I disagree with her reasoning — and ignoring the obvious 'go to a friend's house' loophole — is there really any other way (on a home budget) to netnanny a household computer?"
Move the computer to a public location.
That way you can watch them.
God forbid you actually raise your own child.
"It's 10:00 do you know where your children are?"
As a computer technician I'm sure you've encountered cases before where a user asks you, "How do I do thus-and-so?" when really they're looking to accomplish some goal only tangentially related to what they're asking. Maybe this is best treated as the same sort of problem.
What is the user actually trying to accomplish? Is she worried that her son will become some kind of sex fiend? It's too late -- to paraphrase a line from Buffy, even linoleum makes teenage boys think about sex. Is she concerned that he'll get bad ideas about sex from Internet porn? Maybe some sex education is needed: "Son, just so you know, real women don't like bukkake gang-bangs. They like hugs. And clitoral stimulation too, but hugs first." Does she just have moral or ethical objections to porn in general? Maybe she should be talking about her values with her son a little more.
No matter what the problem is, it's almost certainly a social and educational one, not a technical one. Deploying a technical solution is probably not the answer.
In your internet router, force the dns to use the opendns information...
Works, somewhat well. Doesn't stop you from using google images, though.
