If you are going to be on the road this Thanksgiving visiting your muggle relatives, that would be an excellent time to do them a favor and enable OpenDNS. It is ridiculously easy and I’d bet your hosts will be really thankful if you can ban porn from their homes, especially if there are kids. We talked about OpenDNS on the Mac Power Users ages ago but it is all still relevant. Also, my pal Katie Floyd made this handy screencast.

In this Mac Power Users Screencast, Katie walks you through configuring OpenDNS to filter web traffic on your network, block certain categories of unwanted sites and enable basic security settings. Note from Katie: This is my first attempt at a screencast. I learned a lot during this process and have many tweaks and changes planned for future episodes.
