It stands guard between my modem and my internal server. I don't understand why the pfSense box has two NIC's and the mail/web/DNS has only one, but that's how my LAN guy reconfigured things. one thing I'm thinking of is to get One fast and lower-power server, having two jails. One jail would be as-is with mail/web/DNS and the other jail would be "tao", my main server for years. When I buy a reasonably fast ThinkPad, it could run Ubuntu and I could reconfigure my older boxen for emergencies. > > > > Not that bad if you've got only one box.

Especially as their own costs skyrocket, and as the poor consumers {that's us} start yelping as our power bills hit the ceiling. It will be at least a few years though, so for now, yes, it's our responsibility. > I have to say it was a bit painful > spending £50 on an energy efficient power supply instead of £15 on a > standard one, but the other parts aren't any more expensive. > > I'll redo my measurements in the next couple of days. > > > > >>It's a good idea to turn computers off at the wall when not using them > >>not just shut them down.

The way I see it, since we {us-[BSD]-geeks} are among the most savvy folk on the planet, it's make sense for us to be in the lead on this type of issue.
