produces a WLAN bridge called OSBRiDGE 5GXi.

Clemens HOPFER from FunkFeuer found that the firmware versions 3.39, 3.50, 3.52, 3.54 and [4.01R], as binary downloadable from their website contain busybox, rrd-tools and the linux kernel.

Firmware version 4.01R

The firmware 4.01R contains the following versions of busybox and the linux kernel:

busybox version

# busybox
BusyBox v1.01 (2008.04.14-09:29+0000) multi-call binary

Usage: busybox [function] [arguments]...
or: [function] [arguments]...

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. Most people will create a
link to busybox for each function they wish to use and BusyBox
will act like whatever it was invoked as!

Currently defined functions:
[, ash, basename, bunzip2, busybox, bzcat, cat, chmod, cp, cut,
date, df, echo, expr, getty, grep, head, ifconfig, init, insmod,
ip, kill, killall, linuxrc, logger, ls, lsmod, mkdir, mount, ping,
printf, ps, rdate, reboot, rm, rmmod, route, sh, sleep, syslogd,
tail, test, touch, tr, traceroute, udhcpc, uname, uptime, vconfig,
wget

#

linux kernel version

# uname -a
Linux OSBRiDGE 2.6.22.4 #134 Tue Apr 15 21:44:17 CEST 2008 mips unknown

rrd-tools

The Firmware contains rrd-tools as you can see in the screen shot from the web interface of the OSBRiDGE 5GXi (look at the right border of the graphs - there you can still see the rrd-tools text)

We actually use a 3rd party company to provide the software for us and as a rule that software should not contain any code under GPL license if we are not notified about that fact upfront. We have not been notified about that in this case. If you could provide me information on how we can verify this fact ourselves then that'd be really great.
