Using OpenWRT with WPA-PSK 2 on Broadcom WLAN routers have been stuck on a quite old bug. Recently someone suggested that it may have been fixed in trunk, which caused me to test it. And it works!

It took some time to work out the details here. To save myself time to reconstruct the commands, and hopefully save you some time too, I wrote down how to use OpenWRT with two Asus WL-500g Premium linked together wirelessly using WDS and PSK2 encryption.

The writeup is long, so I put it on a separate page:

If you are interested in using OpenWRT with a 3G connection, you may find my summer house internet writeup more useful.

Procrastinating real work, I documented my home audio server setup. I needed a cross-platform solution, and as a first step, I settled with MPD. The setup is only a few days old, and I may decide to change software eventually. But the current setup works under Gnome, Windows, Mac OS X and even on my Nokia 6233.

What may be missing is FM/DAB Radio and streaming of TV, but I’m not sure the little NSLU2 is up to it. We’ll see.

(This is a continuation of my series to document the devices that run my home, the first was the internet setup).

The timing of an article about the Hitachi 1TB disk (linked via a slashdot post) and the disk situation on my home server was too good to be missed. Hence this.

Oh, and not to be missed: the PopSci explanation of Perpendicular technology.

Spending vacation at the summer house without Internet connectivity? Unthinkable.

The first few days, I connected the laptop to my cell phone using Bluetooth, and then to the Internet using 3G/UMTS.

However, we have more than one laptop here, and the range of bluetooth is limited. I ended up setting up a wireless access point with a PCMCIA slot for a 3G/UMTS card. It has worked flawlessly for several days.

Building software for embedded systems is quite simple today. A returning customer asked me to clarify how to build gsasl and gnutls under uClinux, and I finally created a web page collecting the instructions and patch.

Thought I’d let you know the reason why this blog has been silent for a while: Youbico. It is a new startup company that I’m involved in as head of R&D and investor. The idea is to sell a hardware USB dongle, the Youbico key, for user authentication. Initially we’ll target the OpenID community, but we are working with a number of companies looking to use the Youbico key for other applications.

That’s it basically. Again, check out our web site to find out more.

I blogged earlier about buying the Linux-based Jobo Giga Vu Pro Evolution. On 2007-04-14 I asked about the source code, and on 2007-04-23 I received a reply pointing at this URL. I see now that the file can also be downloaded (much faster) from Jobo directly.

I bought a Nokia 6233 yesterday, because I lost my Nokia N80 a few days ago. One of its important features besides 3G and Bluetooth, for me, is the ability to read e-mail. Unfortunately, the devices has some serious problems with non-cleartext authentication in IMAP. What is strange is that SMTP authentication using CRAM-MD5 and DIGEST-MD5 works fine. Actually, there is more strangeness to it than this… (more…)

I bought a new toy yesterday, altough its silly name almost made me go for the Epson P-5000 instead. Quick testing seem to suggest that the device lives up to its promises, although there is room for improvements in the user interface.

One of my reasons of buying it was for the device to serve as my MP3 server in the office. Alas, the MP3 player is not very advanced. You just select directories, and press play. Crude as it may be, it appears to work.

What was interesting was that the manual says the device includes software released under the GPL, available upon request. Today I sent an e-mail to support@jobo.com to ask for the code. It would be nice if I could ssh into this box and run mpg123 manually. I’ll blog about my progress on that.

Anyway, the machine has some interesting specs:

• AMD Au1200 MIPS processor at 400MHz
• 128 MB DDR-SDRAM
• 32 MB Flash Rom
• 3.7″ VGA Screen
• 80 GB Hard Disk
• 2*miniUSB
• Audio+TV out
• VGA/DVI output (cable not included…)
