Web Content Filtering with OpenDNS (Linux Journal)

Linux Journal takes a look at OpenDNS for content filtering. "OpenDNS is a free service that enables you to block content you deem inappropriate at the DNS level. There's no need for any proxy configuration on either the client or the server. All you have to do is arrange for your servers and clients to use the OpenDNS DNS servers instead of the DNS servers provided by your Internet provider. Once that is done, if users try to access a Web site that provides inappropriate content, they are redirected to an OpenDNS Web site that tells them the site has been blocked and why."
