Network Geography and Topology (Part 2)...

Setting up ICS wasn't so easy the second time, probably on the basis that I forgot to document some steps in the last post.

So, to do things properly, you have to set the router to IP address 192.168.2.x, so the wireless adapter on the Windows PC connects on an appropriate subnet.

Then, on the wireless internet connection, right click properties and enable ICS.

It is probably necessary to set the IP address of the wired adapter to 192.168.0.1, and on my Fedora installation, the Linux box sets itself up on 192.168.0.254.

From the Linux box, you should be able to ping the Windows box on 192.168.2.x, and a good check is to ping a website, the IP address of which can be obtained by pinging from the Windows PC (e.g. ping www.google.co.uk).

If that works, then you just need to set up the DNS addresses on the Linux box. These can be obtained from your ISP, or from the settings in the wireless router. And they are added to /etc/resolv.conf in the format "nameserver xxx.xxx.xxx.xxx", by adding DNS1=xxx.xxx.xxx.xxx to file /etc/sysconfig/network-scripts/ifcfg-eth0:1 (or whatever file as appropriate).

I'll probably struggle to do this a third time, so have to avoid rebuilding my machines...

Volcanic Ash…

At last, someone talking about volcanic ash and closing UK airspace who actually knows what they are talking about...!

Seems to be a right load of nutters commenting on it though. How about a new rule: people who think they know better than the experts don’t get to fly on professionally engineered commercial aircraft; they have to build their own instead…

Performance Issues...

So, after a Vista re-installation, a quick listen to the fan showed that the CPU was working overtime. Investigation with Windows Process Explorer showed that this was down to DPCs (Deferred Procedure Calls), but didn't show what was causing them.

Then I found this blog which very quickly identified the Intel 82562V Network Adapter as the cause. All you need to do is turn off all the Power saving and Wake-on-Lan settings in the Power Management tab of the Adapter properties.

Easy as that...!

FeedDemon

Am currently liking FeedDemon, but not the adverts it subjects you to (unless you pay £9.83 to get rid of them). So good to find out how to disable them for free.

I guess I should be using a more web based solution, but I'm old fashioned: I like downloading stuff to my computer. Should try and grow out of that I suppose...

Engineering Terrorists...

Some terrorists have studied engineering, ergo engineers are more likely to be terrorists...?

Completely ridiculous article from the Guardian Comments section, which seems increasingly full of laughable 'entertainment' as opposed to serious comment... sometimes commentators just do way too much thinking...
