Linux in locked down kiosk-mode?

[eddgge]

I have a few old workstations no longer serving the company. My thought was to use these as internet stations where employees can register their time thru our internal web-based application. I would like to have an environment working like Windows with the SteadyState add-on, access to a limited list of web-sites and no system changes by the user.
I have looked at livekiosk.com and webconverger.com which both meets me criteria when it comes to locking out the user from all system settings, but both seems to be totally open to all web-sites without the possibility for the admin to make a list of “allowed” sites.

Running it from a bootable CD without using the HD seems like the way to go for a surf-kiosk.

Any ideas?

You can use squid to restrict access to certain sites.
squid : Optimising Web Delivery
Linux.com :: Advanced Squid

I know ubuntu has a 'guest session' option, which may suit your needs for not allowing users system access.

Squid is good for allowing access to only one site, another idea if you've only got one site you want to let them visit (which is how it sounds to me), would be to delete /etc/resolv.conf and just put an entry in /etc/hosts for the site you want to let them access.
