I think a lot would depend on how clever your kids are. Since they appear smart enough to bypass a proxy, what is to prevent them from figuring out ways to bypass your script - or even alter it?	[reply]

I guess you are right - any security can be bypassed if you are clever enough. I was just hoping to find a way to hook into the network card and so that traffic went through my script first for approval. Ideally I want to be able to create something that simply runs in the background and limits internet traffic requests to the whitelist. ------------------------------- by me http://www.basgetti.com http://www.kidlins.com	[reply]

Of course you can use Perl, but it may be best to create a proxy: http://search.cpan.org/dist/HTTP-Proxy/lib/HTTP/Proxy.pm	[reply]

A proxy would require me to change the browser settings to use the proxy, right? That is how I am doing it now but all my kids have to do to get around it is change the proxy settings to not use it. I was hoping to hook a bit lower into the NIC so I could watch any browser request. ------------------------------- by me http://www.basgetti.com http://www.kidlins.com	[reply]

Set up a redirect rule on your firewall for all traffic coming from that IP address intended for port 80 on a remote machine to pass first through a proxy on the firewall. This requires a NAT box with filter rules you can control.	[reply]
