IPv6 Connectivity

I'm having a go at setting up IPV6 connectivity for my home network, but I'm not going to go into any detail on it at the moment as I don't really know what I'm doing and I wouldn't want to publish bad information.

What I can say though is that I was quickly and easily able to get an IPv6 over IPv4 tunnel established via Hurricane Electric's excellent free Tunnel Broker service with no waiting around for ages, and I'm basically following Wolfgang S. Rupprecht's Fedora IPv6 Static Tunnel Guide, except using shorewall6 to handle routing and firewalling rather than tweaks to /etc/sysconfig/network and ip6tables.

Kudos to Kustom PCs

Recently I have been having trouble with my i7 desktop/server box overheating. When I first built it, the sensors output looked like this:

In the last week or so, temperatures went up significantly, so much so in fact that the on-board temperature alarm had been going off when the machine is busy:

The reason would appear to be that the CPU fan was going at less than half the speed it had been originally, and never sped up even when the CPU was very hot. So the first thing I did was to clean out the inside of the machine, get rid of all of the dust, unplug and reconnect the CPU fan etc. It made not a jot of difference. I figured one of two things were wrong: either the CPU fan was faulty or the motherboard (a Gigabyte EX58-UD5) was making it run too slowly. Given that the former has moving parts and the latter doesn't, I thought the CPU fan was the most likely culprit. The CPU was bought retail from Kustom PCs in Ayr - they had the best price at the time I bought it and the CPU cooler came with the CPU. I had purchased the motherboard elsewhere. I emailed their Technical Support and quickly got a response back from Graeme, who was going to check what speed the stock cooler ran on a machine there. He found that it should indeed be running faster and mailed me a replacement cooler the next working day. Today I changed the cooler (a fiddly job since I had to extract the motherboard from the case in order to be able to safely apply enough pressure on the cooler retaining clips to get them to go in properly) and the new fan ran at the expected speed:

So, kudos to Kustom PCs for their excellent customer service. I will have no hesitation in buying from them again. They didn't want the faulty cooler back either by the way.
