The Bushfires Royal Commission has been told staff answering calls at the Bushfire Information Line on Black Saturday were unable to see crucial information about the fires because of an IT upgrade.
More than 12,000 Victorians called the Victorian Bushfire Information Line or on Black Saturday.
Calls that were not answered went to Centrelink.
But the commission was told staff there were unable to see the Department of Sustainability fire database because an IT upgrade had accidentally blocked that access.

So on the hottest forecast day ever, and which everyone from the Premier down had warned would be the worst fire danger day ever, Centrelink staff, who are the designated backup responders for the bushfire information line, were blocked from getting the information they needed from the DSE web site?
Apart from the timing issues of IT upgrades to systems that are important to the fire-fighting effort, it appears to underscore the severe dangers of restricting network access unnecessarily.
While I was walking down the street running an errand, I tried scanning for Wifi networks on my N95 phone.
I must have found about 20 or 25 of them during just a few minutes’ walk. Probably every fourth or fifth house seemed to have one.
Many of them appeared to be named after the families living there. Some had obviously default names of common brands… Netgear and the like. A few had gobbledygook names which may or may not have been defaults.
And to my surprise, almost all of them were secured.
Two weren’t — one an apparent Apple network, and one Netgear one, both close by to each other.
Hopefully not too many of their neighbours are sponging off them!
These days just about every computer is networked, and that means they have to have a hostname. So how do you name yours? Assuming there’s no particular corporate standard you have to follow, do you make up a theme, or just give them random names?
At home we have lano and woodley.
At my girlfriend’s place, they’ve called them crunchie and munchie.
The company I use for web hosting names their servers after towns and cities around Australia.
At one job I had, we went Red Dwarf, and ended up with holly (main server), kryten (test server) and hudzen (temporary server).
At another job, we started on The Simpsons, with maggie, marge, homer… then moved onto Asterix, with getafix (very appropriate for a machine that needed patching) and obelix.
So, in building the broadband access machine I’ve found a gift computer (twice as powerful as anything else I owned) that was ‘not working’. After loading XP onto and futzing with it for a while, I figured out that doing anything with the USB port locked up the computer… after a while. I tested the theory by running up a memory/CPU intensive game and letting it run for a few hours. It was happy until I transfered some files off the USB stick. Fault identified. If I want to transfer stuff off the machine, I’ll need to get a USB card, or hook up a network. And I think I’ll do the later.
With fault identification complete, I hooked up the broadband modem (Netcomm NB5) via the ethernet connection (given the USB connection wasn’t going to be working on this machine). Entered the IP of the modem into the browser, and got the modem’s login screen. Everything was good, and I shut down all access other than web via port 80 using the modem’s built-in firewall. Connection to the ISP was established, proxies entered into Firefox (not IE – CERT says there are no secure versions), and Google was available. Connectivity proven.
The web browsing machine got Fedora Core 3 loaded on (a simple process), and the proxy setup was repeated with the same results. FC3 comes with a pre-release version of Firefox, so I loaded up the CD with the .gz for 1.0.4 and loaded that onto the desktop. Then I spent a couple of hours figuring out that I needed to be root to install the browser, and where to install it. Having done that, I still haven’t got it as the default browser – that’s still the prerelease Firefox. But I can run up 1.0.4 from the command line, so at least it’s available, and adBlocker is installed, so well and good.
I figure that I’m going to lock the modem down to a single IP address it’s going to talk to, the FC3 machine. Anything else that wants data from the net is going to have to transfer it from the FC3 machine and won’t be exposed to the big bad internet, because I’m not ready to migrate our entire PC collection over to Linux just yet.
Which means I need to buy a switch.
