libdvbsi++ is an open source C++ library for parsing DVB Service Information and MPEG-2 Program Specific Information.

As of today, Metz doesn’t publish open source code on its company website, but you may ask their customer support and they’ll send you a CD-ROM. I received a disc containing source code for Chassis 610/611/612 LCD-TV models.

These devices are used by customers of Deutsche Telekom as ISDN-to-SIP gateways. Currently there doesn’t seem to be much public information about it, so I’ll make a start.

The ipw2200 device driver limited me to use only 11 channels for wireless LAN, even though I bought my notebook in Germany, where channels 1 to 13 may be used. Although other people on the net faced the same problem, nobody came up with a simple and permanent solution like writing the country code to the card’s EEPROM with just a few commands.

For those of you who operate DNS services using Daniel J. Bernstein’s famous djbdns, autoaxfr “lets you emulate the functionality of bind’s type slave zones with a masters list of IP addresses”.

Debian GNU/Linux contains a command line based FTP client, which has been enhanced to understand the AUTH SSL command. This is a good thing, but AUTH SSL has been superseded by AUTH TLS.

Netgear produced a wireless LAN router, which besides of its bad routing performance is quite a nice piece of hardware. If you want it to load a Linux Kernel via TFTP, you will have to modify its NVRAM settings. I wrote some small helper tools which can be used for that. wgt634u

Once I met Collin R. Mulliner at the university, he told me he was having fun exploring weak bluetooth stacks. I liked the idea, and some days later I bought a bluetooth dongle. It was quite a surprise to me that my phone, a Nokia 6310i, silently accepted AT modem commands on some RFCOMM channels without pairing. Later I discovered that some Ericsson phones had the same kind of vulnerability. This is the C code which I wrote while learning how to use the bluez stack and how to get data from a phone using AT commands.

For some time I used a notebook, which was equipped with an M4 mobile graphics chipset. Unfortunately the framebuffer driver of Linux refused to work with it. Instead, funny color shapes appeared on the screen every time the notebook booted. Knowing that the XFree86 driver worked, I started to compare both drivers. It turned out that the driver included in Linux 2.4 didn’t have support for flat panels at all. So, with kind help from Andi, who wanted to use it on his Mac and who is an experienced DirectFB developer, I wrote this new framebuffer driver for Linux 2.

If you write software for a badly documented or undocumented device, then it is sometimes easier to just sniff some bytes of data sent by the original software instead of using a disassembler. Milk is a great software which can be used to capture I2C traffic. To make its output more verbose I modified it to include register names where available and to calculate some stuff for the devices used in the Nokia dbox2.

Here are some pointers to documentation I wrote about the linux@dbox2 SDK. INSTALL.en FAQ.en README.3rdparty.de
