Linksys WRT54G and the GPL

Wow, thanks for the pointer! I just visited the Buffalo site
http://www.buffalo-technology.com/
and I could not find any source code. And not only are they distributing the linux kernel and BusyBox, their rom is _remarkably_ similar to the Linksys one in many respects. Perhaps they share an upstream vendor that did not make them aware of their responsibilities?

Here is a script I just whipped up to open up their firmware...

#!/bin/sh

wget http://www.buffalo-technology.com/download/firmware/wbr-113b.exe

# Next I used wine (20030408) to extract the content wine wbr-113b.exe

# Move into the directory into which the firmware was extracted cd Wbr_1.13b

# I noticed a GZIP signature for a file named "piggy" at offset # 62 bytes from the start, suggesting we have a compressed Linux # kernel
dd if=wbrbg-113b bs=62 skip=1 | zcat > kernel

# Noticed there was a cramfs magic signature at offset 786466 dd if=wbrbg-113b of=cramfs.image bs=786466 skip=1 file cramfs.image

sudo mount -o loop,ro -t cramfs ./cramfs.image /mnt ls -la /mnt/bin
file /mnt/bin/busybox
strings /mnt/bin/busybox | grep BusyBox /usr/i386-linux-uclibc/bin/i386-uclibc-ldd /mnt/bin/busybox

It seems my Dad will have another letter to mail out in the morning!

Fry's appears to be selling a lot of Linksys WAP-54g units, which are low cost wireless access points. For firmware version 1.06.03, the cramfs starts at skip=24576c, bs=32c.

Has anyone had a lawyer write and advise Fry s yet ? Hey theory seems to work for SCO 8)
