I'm at the point w/ flashing firmware where I feel like I need to use a debugger w/ JTAG. I figured I could probably use serial line logging somehow but JTAG seems better and I should learn it anyway. Has anyone pried open the shield on a c139/c140 and tried attaching to the JTAG test points that are just inside the shield next to the test points which are accessible via the battery compartment?

[PATCH] Add generic LE/BE load/store uint type convertors and use them in msgb

by ☎

Attached is simple patch which adds little-endian & big-endian macro to move bytes to and from multibyte integer types like uint16_t, uint32_t etc. Some of this code is used right away in msgb.h but it will also be used in kasumi implementation later on. -- best regards, Max, http://fairwaves.ru

[PATCH] RFC - change GPRS cipher API

by ☎

Hello. Attached is a trivial patch which breaks existing GPRS cipher API of libosmocore by switching from fixed 64-bit length Kc to variable-length. There are several justifications for that: - compliance with ETSI TS 155.22 (GEA4 - 128 bits Kc) and all further versions - similarity to existing auth api (osmocom/crypt/auth.h uses 128 bits as well) - nobody uses this API anyway (except my other patches with GEA) - patch breaks nothing within libosmocore (make check succeeds) and openbsc (uses gea0 only) That's why I think next libosmocore version should apply this patch and change unused API before someone actually start using it and makes transition more difficult. -- best regards, Max, http://fairwaves.ru

EMI firmware: Decoding Dummy frames

by Enrique Saez Gil

Hi all, I have been experimenting for a while now with the EMI firmware. My goal is creating a controlled interference for an experiment. My current setup is the following: - one osmo phone with the EMI firmware transmitting on a single time slot - one USRP2 at the receiving side I use GNURadio for sampling and Matlab for post-processing. My problem is that once I analyse the received bursts in Matlab I am not able to decode its content. I expect to see the same sequence repeated over time since Dummy Burst are being transmitted as detailed in the wiki. However, this is not the case. After going through the code I am not sure how the transmitted sequence is generated, neither the cyphering sequence used. Could you help me with these issues? Thanks, Enrique

Osmocom Trx with OpenBTS

by Hassan Mourad

Hi Guys, So I was trying to use my osmocom phone as a transceiver for openBTS. I followed the procedures indicated in this link " bb.osmocom.org/trac/wiki/Software/Transceiver" and was able to successfully load trx.compalram.bin on the phone, connect openBTS to it and sync the clock to the strongest cell around I got the output attached from openBTS For some reason however when I search for the network I am unable to find it. I can not figure out what exactly is going on here and I was wondering if any one can help One thing to point out is that I was never able to set the below value to the suggested value as it was not in OpenBTSs configuration options. I am not sure if this has been deprecated or replaced by any other options GSM.CellSelection.Neighbors = (set to empty string) Any help would be appreciated Starting the system...

RE: Welcome to the "baseband-devel" mailing list

by Sébastien

Hi all, I am new on this open source community. I am a looking for a "basic" open source code that would be compliant with the UMTS standard. By basic I mean, I would simply try to manipulate my RTL2832u-based DVB-T dongle (on a R-PI) to make it reaching let's say the neighborhood cell IDs plus their corresponding receive power. Maybe I am stupid, but despite the time I have spent on the websites and while there is a lot of very interesting stuffs related to GSM/GPRS/LTE standards: I could not find anything compliant. Even AT command would sound good to me in a first time. Thanks for your answers or even for any clue, Cheers, Sébastien

Re: [Openbts-discuss] OpenBTS / E100 & GSM attacks.

by Hacker Fantastic

Hi Michael, It is my intention to share an image and speed the process up for other researchers interested in GSM attacks and building simulations in their labs. At this time there are code changes I want to expand upon before I do (predominantly cosmetic changes and making it more feature useful from the python script). I am also hoping that enhanced detection of fakeBTS attacks will be expanded upon by the osmocom-bb toolkit (the launch of the detection capability occurred in December 2013 at CCC.) which would sufficiently detect anyone attempting to use tools of this nature in an illegal way. Most of the work I did can be recreated from the slides previously provided. If you are interested in the E100 platform, I spent alot of time exploring its capabilities and re-compiling packages. I first started trying to build the firmware from scratch with some discussion occurring between myself and the firmware developer at Ettus, eventually it became easier to customize the firmware provided by Ettus - the most difficult change being a cross-compiled kernel to enable netfilter so that IP routing became practical thus allowing for GPRS capabilities. I also had issues with the OpenBTS 52MTransceiver application in the more recent commits as significant overhaul has begun on changing its capabilities. I eventually settled on r6718 version as this provided GPRS capabilities and also was the last version functioning with the 52MTransceiver application. Most of the firmware I had to rebuild from source including things not available in package repos such as libpcap, asterisk (w/ODBC), odbc, libsqlite and python to get the capabilities I needed to demonstrate the practical elements of a GSM attack from an embedded device. I will be releasing the firmware image as soon as I tidy up some of my python code and detection tools become more effective. If you do really need the image for some research purpose then please e-mail me directly and I will gladly share a copy with you providing I can understand better your requirement for needing an off-the-shelf attack tool for GSM.
