hello,
I am not quite sure if this is the right place to ask, so sorry in
advance for spamming ir i'm in the wrong place.
I have build and run osmocom on my C123. I am using it for a university
project and we try to read parameters from surrounding BTS. The final
goal will be to separate real bts from imsi catchers.
So my question is, can I use the osmocom library to gather some data
from surrounding BTS? Are there some example programs? Would anyone know
a good way to read the SIM data from the connected C123?
Thanks in advance!
Cheers
Tom

Short example scenario: A very obvious catcher fault would be not having
set the regional code or having set a wrong regional code. So it would
theoretically be possible to read the regional code from the own SIM
card and the regional code of the transmitting BTS and compare those.

Hi Tom,
have you looked at the source yet?

Thanks for your quick replies. I have not yet looked at the code, since
somehow the mails haven't been forwarded to me. I just stumbled upon the
website and read that there were answers to my post. I will look into it
this weekend.
At the moment there is not git repository since I am sitll in evaluation
phase. It is for my masters thesis. I will definitely make the repository
public once I start working on it.
For now I have played around with the mobile application. "show ba 1" could
yield a list with band allocations of networks (correct me there if I am
wrong), I geuss this might be the stations that are around this area.
"show cell 1" gives some information on the connected cell. I have seen that
there is an option to put the arfcn behind the "show cell 1". does this mean
you can scan a arbitrary cell of which you know the arfcn?
I also put a SIM card in the c123 and tried "show subscriber 1" which yield
"No SIM present". Do I have to specify the SIM in the mobile.cfg maybe? IS
there any example mobile.cfg or some docs on the format?
Thanks in advance for your time.
Cheers
Tom

I think that cell_log is the right osmocom app to start from. As its
name said it's an application that logs data from cells...
Slight changes can give you whatever you need.

Hi,
one more interesting question (hardly learned from the past), will you develop
the code in the open? What is the URL of your git repository?
