Need to Restrict Laptop to just ONE Website - How can that be done please?

[Linux101]

I KNOW it can be done ..
However, in my attempts, Ive extended the perimeter of my bald spot by about 30%! <sigh>

I have 3 laptops, all of them need to access just ONE specific Website, no other sites. Infact, we dont need, any email, any sound, ...) Id prefer to remove the Hard drive and just have them boot up from a CD, That way I dont have any problems about Anti-Virus software, Hard Drive Failures, etc ... They are just outdated laptops with built in Wireless LAN

What Id prefer - is if a guy could make a Bootable CD, (either with the Windows product thats in them, or something like "puppy linux" for example) and just have a way to use something like firefox or what comes with pupply linux that could limit the access to that one single website.

Can someone please give me some ideas, or
(Hint: Better yet!... an .ISO I can download from somewhere would be AWESOME! -
(I was thinking about Puppy Linux, but I dont know enough about Linux, or Coding to make it happen)

Thanks!
Happy New Years!

You could try running iptables and configuring port 80 to only connect to the site in question. Alternatively, you could set up a proxy server and have all HTTP traffic go through that proxy server to the ONE website you choose. The latter, of course, could be overridden by the user. The former would require a moderate level of knowledge of iptables. The only way to get away with that is to set the ownership of the iptables configuration to be world readable, unwritable by anyone, and execubable by the owner. Then you set the ownership to the daemon which runs iptables or root. Do not give the root password to the users (or better yet, remove the root login capability). You may be able to change the permissions to something more restrictive than I suggested, but I can't be sure as I haven't actually done this. I see no reason to restrict users' access on Linux in any way, but if your religious beliefs or product specifications demand it, I guess I should not judge.

As for an iso, I am not quite certain, but I did see something called sphirewall which will set up a firewall box similarly to what I suggested. You might look into that as a base.

If I understand you correctly, what you are suggesting is to just to into the ROUTER to do this? Or is it more complicated than that?
