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, go to products->networking and you'll find it 
 A friend of mine bought one today.
 I first ran nmap against this device, and identified it as running linux 
 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 
After i downloaded it (C100BRS4H_2.97.bin) and ran the strings command i found 
the following significative strings: 

 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 

This is nmap output:
