Why not block all ports except 80 and 443 for that host during certain times during the day? -----Original Message----- From: Vince Littler [mailto:suse@archipelago.eclipse.co.uk] Sent: Saturday, April 08, 2006 4:26 PM To: suse-linux-e@suse.com Subject: Re: [SLE] How to do Internet access restriction?

Then he wins.
I would like to trick the dns!!! I want to update the dns for his computer for certain hours to access the on-line game or not.
Dynamic DNS would be something I could imagine would work.
From the dns log I know which destinations he need. I want to divert these destination to a certain web site (if it access a web site). Or make a bandwidth restriction to certain hours would be another
choice.
My concern is, that only the games are restricted, but not any web site he might need for school. I want to make this on the server! Any ideas?
Avoid this approach. OK, this is a Linux list and the reasons for avoiding this approach are probably off topic, but in essence you are putting yourself in a position of controlling someone who is becoming an adult and who needs to learn to control himself. By constraining what is possible, you are teaching that anything which is possible is permissible. That's a bad lesson, and you should be prepared to sacrifice all the schoolwork in the world to avoid teaching it. It's a familiar question, and you are a good deal more open about it than many - I have several times seen it, without a child being mentioned, and someone replies and mentions 'your child' - at which other posters say 'what child' - and then it turns out to be a child who is being controlled, sometimes a 17 year old. And then the thread goes sour, when someone says 'perhaps you should not try to exercise control in this way' and the original poster says 'who the hell are you to tell me how to bring up my child?' At 13, you might think it is appropriate to do control by technical means, but then you will need an exit strategy over the next few years during which you will be working through all the things you need to work through now, only a few years late, with a more resentful son. Or you could let him leave home, go to college at 19, never having exited from this control at home, and he will not have learned self discipline, with predictably bad consequences. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com

I've just added an entry such as 127.0.0.1 www.ebay.com into /etc/hosts So far it has saved me a bundle. A simple cron job could be used to swap the file if you want to permit it at certain times. mv hosts.bac hosts.tmp mv hosts hosts.bac mv hosts.tmp hosts
