I posted  on the GPL-violations mailing list, but got no response, so I'll
It seems Canyon  distributes  a firmware update file 
for their CN-WF514 WLAN router that contains the linux kernel
image. nmap scan guesses the router is running "Linux 2.4.X|2.5.X"
There is no mention of used GPL software and no source code.
A direct enquiry to Canyon was responded with :
This product is not using GNU GPL license.
(yes, that's all of it)
What I need :
Help disecting the FW package . It is a ZIP archive containing
a text file and a *.bin file. This *.bin file appears to be some kind
of another archive, containing two files : webpages-6104ipc.bin
The *.bin archive file begins with the string "WBIP". I guess it uses
compression, since "strings" does not give out anything useful, except
the mentioned two filenames.
There is another firmware update  that is in slightly different
format. "strings" there finds this :
Ok, booting the kernel.
Any ideas ?
As this is partly off topic for lkml, I suggest replying to the gpl
violations mail list.
Here is what I asked Canyon and got the above answer :
Is any software distributed with the CN-WF514 router,
that is licensed under the GNU General Public License ?
Hm, maybe they thought I'm talking about the acompanying
CD media ...
