Another thing I do is I've placed a line coupler from radio shack (one of those phone cord extension female to female sockets) on my phone line. I have a T1 connection via phone line and its on all the time. When I don't need the internet I simply decouple the line. I only couple when I want to access something. I think people who just leave their line on all the time even if they don't need access are raising the chance of getting nailed by a huge factor. If you're not connected, you can't get hacked. Just plugin when you want access and decouple otherwise and DON'T leave your machine connected and on over night.
