I think something's wrong with my headphones (and my network)
  
Today, after lunch, M****, A******, Pop/Mark and I did go for a walk around Bolton-le-Sands. We have the A****** unit potty trained (although often he'll require reminders), but still worry slightly what happens outside of the house and whether A****** knows the score. Thus, any suspect movement/utterance on A******'s part that could be interpreted as the need for the toilet tends to send us into a bit of a panic. Ah well. It's all good.

So yeah . . . I think these last four photographs are largely of the same thing, but I couldn't decide upon my favourite, so I've left them all in. Hmmmmm. And tonight I did watch the film Sunshine, whilst M**** was enjoying a meal at the Borough with Liz and Mark. But yeah . . . Sunshine - damn fine film. I give it five stars. Tonight I have also been playing around with a computer (cobbled together with spare parts), trying to get it to behave as a router, but also as an exercise in networking, routing and such-like. However, something very puzzling is happening . . . It has two network cards, yeah? So far so good. Both of these networks cards are acknowledged by the operating system as eth0 and eth1 and seem to be working fine. I've given them static IP addresses, 192.168.0.10 and 192.168.0.11. From any machine in my network, I can ping and connect to that machine via either of these IP addresses. So all good so far. But then I started thinking, "But which network card is eth0 and which is eth1?" So, on my main PC I open up two terminal windows and in one I ping 192.168.0.10 and, in the other, ping 192.168.0.11. Both ping back, as expected. So, then comes the weird bit. I unplug one of the network cables and both ping requests carry on being answered. Eh?! I unplug the other network cable and both ping requests stop (destination host unreachable). So one of my network cards is both eth0 and eth1 and the other network card is just sitting there doing nothing. How is this possible? What is going on?
