Problem compiling OsmocomBB on BT4 RC2
by quem tu quiseres 18 Jan '11

18 Jan '11

Hi, I just started playing around with this great project and am ashamed to say I'm stumped with an annoying error when compiling. I'm compiling on a Backtrack 4 RC2 (*buntu based distro) and that may be why I'm having problems. Basically I downloaded the proper packages as per the instructions on the wiki, exported the PATH and all that, but when I run make I get this error: cd shared/libosmocore/build-target && ../configure \ --host=arm-elf-linux --disable-vty --enable-panic-infloop \ --disable-shared --disable-talloc --disable-tests \ CC="arm-elf-gcc" CFLAGS="-Os -ffunction-sections -I/root/GSM/osmocom-bb/src/target/firmware/include" configure: WARNING: If you wanted to set the --build type, don't use --host. If a cross compiler is detected then cross compile mode will be used. configure: error: cannot find install-sh or install.sh in ".." "../.." "../../.." make: *** [shared/libosmocore/build-target/Makefile] Error 1 Attached is my config.log and you can see the PATH are there. The error can be seen on this line in the log "configure:1766: error: cannot find install-sh or install.sh in ".." "../.." "../../.." Now i've checked to see if I have autoconf and automake installed (I do, I have autoconf 2.61 and automake 1.10) since my searches on the internet seem to indicate that maybe the problem. Now I usually do all my own leg work and I read and read before asking questions, but I'm afraid I can't resolve this on my own. Before I spend another afternoon searching for the solution, I remembered to ask here. Anyone have any hints on what I'm doing wrong? Do I need different automake or autoconf versions? Thanks and keep up the great work. It's been fascinating to watch the evolution of GSM hacking these last few years.

Sim on C115 & C118
by Dario Lombardo 18 Jan '11

18 Jan '11

Hello everybody I'm trying to run the "mobile" application on a C115 and a C118 phone. I want to use the real sim, so I used "sim reader" in the config. Both phones have the same behaviour: <000e> sim.c:1206 init SIM client <0005> gsm48_cc.c:61 init Call Control <0001> gsm48_rr.c:4944 init Radio Ressource process <0004> gsm48_mm.c:1220 init Mobility Management process <0004> gsm48_mm.c:971 Selecting PLMN SEARCH state, because no SIM. <0002> gsm322.c:3471 init PLMN process <0003> gsm322.c:3472 init Cell Selection process Mobile '1' initialized, please start phone now! VTY available on port 4247. <0004> subscriber.c:556 Requesting SIM file 0x2fe2 <000e> sim.c:209 got new job: SIM_JOB_READ_BINARY (handle=00000004) <000e> sim.c:697 go MF <000e> sim.c:241 SELECT (file=0x3f00) <000e> sim.c:187 sending APDU (class 0xa0, ins 0xa4) no more output beyond this point. Phones work correctly with other softwares, sim works correctly. I get no response from the sim. Is the card reader working on these phones? If yes, does anyone have suggestions to solve this issue? Thanks a lot to everybody. Dario.

C115 loader.compalram.bin
by list_mailing＠libero.it 16 Jan '11

Hello. I'm trying to load the loader.compalram.bin. The behaviour is very strange because sometimes the download is complete and successfull, sometimes; in particular, in this case, the download is complete, but any ACK is sent back from the mobile phone (see below). ./osmocon -p /dev/ttyUSB0 -m c123 ../.. /target/firmware/board/compal_e99/loader.compalram.bin got 2 bytes from modem, data looks like: 2e c8 .. got 5 bytes from modem, data looks like: 1b f6 02 00 41 ....A got 1 bytes from modem, data looks like: 01 . got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD read_file(../../target/firmware/board/compal_e99/loader.compalram.bin): file_size=21752, hdr_len=4, dnload_len=21759 got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: f6 . got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 43 C Received PROMPT2 from phone, starting download handle_write(): 4096 bytes (4096/21759) handle_write(): 4096 bytes (8192/21759) handle_write(): 4096 bytes (12288/21759) handle_write(): 4096 bytes (16384/21759) handle_write(): 4096 bytes (20480/21759) handle_write(): 1279 bytes (21759/21759) handle_write(): finished The target phone is C115. I tried compal_exx and the result is the same :-( Please, can someone help me to understand the reasons? Thanks in advance.

running voice data/encryption on compal?
by Aaron Zauner 16 Jan '11

16 Jan '11

hi, a while ago i've read that someone managed to have an active phone call over osmocom for about 20mins. i woundered if it is theoretically & technically possible to have an active, serious (thus not a5) encryption running for voice or data calls on the stack? thanks in advance & greetings from vienna ;) azet

[PATCH libosmocore] gsm 03.41: fix GSM341_MSG_CODE macro argument
by Alex Badea 16 Jan '11

16 Jan '11

One usage of the "ms" argument is typoed as "msg". Fix it to prevent subtle future failures. Also paranthesize the macro argument for good measure.

open cell phone hardware questions
by Scott Weisman 16 Jan '11

16 Jan '11

Hi everyone. I'm admittedly more a lurker than an active participant in this project. I find it very fascinating and regard its objectives as important. I recently watched several of the C3 presentations, from this and previous years. Having open, documented hardware and software seems to be an important goal in itself. Just knowing about all the potential weaknesses in the software stacks of most phones, as well as hidden "features" like SMS messages that could, theoretically, do things like remotely enable the phone mic, among other things (things that are certainly technically possible, and also due to the closed nature of the software, completely unknown) are of grave concern to me. Now, given that the supported phone hardware is old and not reliably available, I was wondering if anyone knows if the Calypso and other chips in these old phones are still available for new designs? How much interest would there be, say, in an open, but VERY SIMPLE, actual phone? Kind of like the Pandora project, but without the ambition to make the most advanced portable game player possible. The Osmocom software would then be very easily portable to such a device. Given the seemingly widespread interest and enthusiasm for the Osmocom, OpenBTS, and OpenBSC projects, a real, genuinely open phone (not a pseudo-open phone like the FreeRunner) might possibly have enough interest, and be buildable for a low-enough cost, to merit further discussion. Anyone want to discuss this?

TODO: OsmocomBB to continually iterate over all cells and dump SI
by Harald Welte 15 Jan '11

15 Jan '11

Hi! A number of people want to do some long-term evaluation of their cellular environment and would be interested in an 'app' for OsmocomBB that continuously scans the spectrum and dumps the cell parameters such as * ARFCN, Signal Level, SNR * frequency synch offset * SCH info (BCC/NCC) * SI (at least 1-4) from BCCH I would love to do it, but I simply don't have the time. I thought maybe somebody on this list is looking for a relatively simple task and has some time. I think this is a great project to work with OsmocomBB without having to go into the details. The algorithm would look something like STATE 1: Power Scan * do power measurement over all supported bands * pick strongest N carriers and iterate over them STATE 2: FCCH/SCH acquisition * try to get lock on the carrier * if not, go back to next carrier from power scan * if yes, continue with STATE 3 STATE 3: Wait until all relevant SI have been received * generate GSMTAP output for the SI messages (or timeout) * go back to STATE 2 for next strongest ARFCN * after last ARFCN, re-start from STATE 1 This is basically the initial step of the GSM 03.22 cell (re)selection that we already have as part of the 'mobile' program. So all the code is there, but what's needed is a separate rady-made app, not requiring any user interaction. It should also include some e.g. shell script that automatically generates a new pcap file every N minutes/hours, and make sure to never overwrite any existing PCAP file. In the end, having this running for an extended period of time should simply produce a large number of PCAP files without any manual interaction. Lock-ups in any state should be detected by timers, singalling a proper L1_RESET to make sure it continues. Unplugging / re-plugging the phone should also not require any re-start of the program. Optional extensions: * software to aggregate info from the pcap files (remove duplicate entries, e.g.) * optional logging of GPS coordinates from a GPS receiver If anyone has some time to give this some work, I'd most appreciate it. Please inform the mailing list to ensure no duplicate work is created.

Everyone, Is it true you can use a MTK Chipset as a DIY GSM BTS/USRP ? I've emailed this fellow who posted this back in December 2010 but have gotten no reply to date. This would be excellent for use on something I'm working on in Africa for about 50 - 100 IMPOVERISHED villages. Awaiting anyone's input on this.
