Interesting study, I have seen quite the same configuration on a very common broadband router sold in France. There were also operator-defined data stored in the configuration files, such as the VoIP gateway parameters, the administrative console IP address, and the like. FYI, I think the operating system is an ATMOS/ISOS rather than a GNU/Linux. In my case, there was also an undocumented but very useful command : "debug". It was only available through the console port, but if it works for you, you will access a kernel mode debugger. Regards, - Nicolas RUFF
