I'm a linux newbie, so i'm stifled by the simplest things.  I'm using fedora 2, and i need to know how to restrict website access from that computer, baised on the user logged in.  For example:

Kids: No porn; No Websites that i've specified
Me: Wide Open :)

so if the kids are logged on, they can only get to websites i specify, but when i logon, i have full access to browse any site.  Any Suggestions?

The bestthink to do is apply a proxy server and restrict sites squid is a well know proxy

http://www.squid-cache.org/

Within squid you can divide different groups and different lists of accessible domains. It has lots of other options to like limiting maximum size of downloadable files, etc.

Use squid, but also use iptables rules to prevent restricted users from bypassing your proxy

Although Squid could provide what you need I would also check out  DansGuardian http://dansguardian.org/ which will provide real content checking. The problem with using a proxy is that you have to allow/block addresses/sites. You don't control the content.

Twisted_Mystic - Clearly the other answers also have merit - Especially squid and dansguardian. If you leave a message in the community support fiorum and ask them to redistribute the points I wouldn't object, and it's only fair that their contributions are recognised as well:)
