GPL violation by router manufacturer Conceptronic

GPL violation by router manufacturer Conceptronic

[Miguel Angel Alvarez]

Hi all! 

 I have found what may be (it surely seems to be) a GPL violation by 
Conceptronic (it was Tulip computers some years ago).
 They sell a router, actual model is C100BRS4H. Their web page is 
http://www.conceptronic.net, go to products->networking and you'll find it 
here. 
 
 A friend of mine bought one today.
 I first ran nmap against this device, and identified it as running linux 
2.4.18-2.4.20 
 Then I asked my friend to look for GPL notices and source code on the 
documentation and he could find none. 
 So, I went to the manufacturers web to look it myself, and could find no 
reference to linux or GPL code. What I found was and actual update to the 
router's ROM. 
 The download site is 
http://download.tulip.com/support/Conceptronic/Network/C100BRS4H/ 
After i downloaded it (C100BRS4H_2.97.bin) and ran the strings command i found 
the following significative strings: 
 webpages-6104k.bin 
 vmlinux.bin 

 I couldn't dig more since I don't know what proccessor has the device nor 
what compression algorithm they are using. 
 The rest was garbage, so i suposse this are two compressed files. 
 I searched in google, but i couldn't find any reference to this particular 
violation, just another violation in a wireless router from same 
manufacturer.

This is nmap output:

Try this:

tail -c 1717886 C100.bin > webpages-6104k.bin.gz
tail -c 1652350 C100.bin > vmlinux.bin.gz

It's an MIPS kernel:
~  (Linux version 2.4.18-MIPS-01.00 (root@betty_linux) #318 ... 18:01:58 CST 2004)

If you look at the size of the firmware file, I'm not sure, if there are only
these two file in there...

sorry for my late reply, netfilter-devel is not the right place for this
kind of mail, since it is about development.

Please direct gpl violations of netfilter/iptables to
laforge@gpl-violations.org, which I read more frequently.

Anyway, I'm going to reply to you privately with more informtaion.
