OpenWRT up and running!

Just got OpenWRT running on my Linksys WRT54GS access point / router. I can now ssh in, install extra packages.. I’ve got about 4MB of flash left to play with now (after installing tcpdump, strace and a web front end).

It’s all looking pretty cool.

Alternative Linksys WRT54GS firmware (update 1)

I’ve mentioned the Sveasoft firmware for the Linksys WRT54GS access point / wireless router, but now I’ve come across another alternative called OpenWRT which appeals to my UNIX sensitivities.

Rather than give you one big distribution it says:

OpenWrt provides only a minimal firmware with support for add-on packages. For users this means the ability to custom tune features, removing unwanted packages to make room for other packages and for developers this means being able to focus on packages without having to test and release an entire firmware“.

A refreshing application of the UNIX philosophy of joining small tools that do a single task well to firmware – Create a small but easily extendable base system and make many packages available for it. The OpenWRT website is well worth browsing, it’s all out in the open including a CVS repository and forums.

Update: I’m now playing around with a version of the Freifunk Firmware (also based on OpenWRT) that has been customised for Melbourne Wireless – I’ve got two Linksys WRT54GS’s up and linked with it as a test in my back garden.

Maldives – the first nation to disappear because of global warming ?

The BBC News service is reporting that the Maldives may disappear as a nation due to global warming.

Sea rise there is just under 1cm a year and: "Since 80% of its 1,200 islands are no more than 1m above sea level, within 100 years the Maldives could become uninhabitable".

The Maldives was the first country to sign up to the Kyoto Protocol and has since written to President Bush in an attempt to get the US to sign up (as they’re a major source of greenhouse gases), but the US hasn’t even bothered to reply.

What makes this more disturbing is growing evidence (as reported in New Scientist magazine of 24th July) that the effects of clouds have probably been underestimated in global warming as a feedback mechanism. The latest moves by the Intergovernmental Panel on Climate Change to weed out poor models that fail to predict climate change seems to be removing those that predict lower increases in temperature and do not take good account of cloud change.

The remaining models which do take better account of clouds are generally predicting higher temperatures, some predicting up to a 10C rise in global temperature for a doubling in carbon dioxide, rather than the currently accepted 3C rise. Now this can only make the future even more bleak for the Maldives and other low lying countries.

The BBC report doesn’t address the rather obvious question of what happens to the population of a country that disappears under the waves, through no fault of their own. Do the major polluters have a moral responsibility to take them in, and/or to make reparations ?

UK to get its own Anti-Terror Fridge Magnet ?

The Guardian is reporting that the UK will get its own "anti-terror pack" which leads me to wonder will they follow the lead of the Australian government and ship everyone an anti-terrorist fridge magnet ?

The ABC’s 7:30 Report has a regular (and very good) political comedy sketch on Thursdays done by John Clarke and Brian Dawe, sort of "Monty Python meets Yes Minister".

In February 2003 they they took a hilarious look at this pack, including this snip:

INTERVIEWER: Could you tell me what this is?

JOHN HOWARD: This is just a letter, Bryan, to Australians explaining the geopolitical position and counselling them not to worry too much, not to panic.

INTERVIEWER: Not to worry unnecessarily.

JOHN HOWARD: No, don’t be too alarmed.

INTERVIEWER: And what’s it called again?

JOHN HOWARD: You can see what it’s called.

It’s called “Look out! There’s A Terrorist Behind You With An Axe”.

INTERVIEWER: And this is a fridge magnet?

JOHN HOWARD: It’s a fridge magnet, Bryan, yes.

INTERVIEWER: And what’s it for?

JOHN HOWARD: For sticking on the fridge.

INTERVIEWER: But why?

JOHN HOWARD: So you don’t get attacked by terrorists.

Oh, we sent our pack back, return to sender..

Mountain Goat Beer – yum!

Donna and I went over to have dinner at some friends on Saturday night, so whilst shopping in our local organic shop that morning I came across a beer called Hightail Ale from a company called Mountain Goat Beer, a small microbrewery in Richmond in Melbourne.

They describe Hightail as "a traditional English style ‘real ale’" and they’re not kidding. It was a lovely taste of home, even if the heathens were keeping it in the fridge! 🙂

A very nice suprise to find, and I think it’s going to be well worth exploring their other brews!

Linux wireless stuff

A pair of Linksys WRT54GS’s turned up today. 🙂

They run Linux internally and you can get replacement firmware from a variety of sources (including SVEASoft) to allow you to do funky things like VLAN the ethernet switch and port all your favourite software to it (including Kismet)!

Personally I think Linksys deserve a lot of credit for doing this, and they certainly seem to be getting a lot of customers down here because they’re so easy to hack about and customise. Nice one folks.
