Sniffing GPRS
by canarion 12 Dec '16

12 Dec '16

Hi, After compiling osmocom-bb and apply sylvain/burst_ind branch and gprs_multi.patch, I execute it and try to sniff gprs traffic. I loaded the layer1 into my C139 and I obtained an ARFCN code (883). When I run ccch_scan -a 883 I get the next result: opyright (C) 2010 Harald Welte <laforge(a)gnumonks.org> Contributions by Holger Hans Peter Freyther License GPLv2+: GNU GPL version 2 or later <http://gnu.org/licenses/gpl.html> This is free software: you are free to change and redistribute it.

layer2/3 ported to target? paging attack code?
by Craig Comstock 05 Aug '16

05 Aug '16

Hey, I finally watched Nico's talk "let me answer that for you" and heard him say he ported layer2/3 to target. Also found a mailing list message about him cleaning it up and putting it up on git and sending it to a few folks. Did that code ever get shared? Would be cool to play around with and is certainly something I would eventually want to accomplish for my project of making a phone that works by itself. -Craig

Also when i tried to run Mobile i get the :- even though i created the Mobile.cfg file in /etc/osmoco Failed to parse the config file: '/home/raz/.osmocom/bb/mobile.cfg' Please check or create config file using: 'touch /home/raz/.osmocom/bb/mobile.cfg' I have spent some hours researching the lists and trying various things to no avail but I want to continue until I resolve this issues and use this great stack to learn about the GSM network. Please advise. Great full for any help or pointers but this maybe a timing issue that is difficult to debug. Thanks Raz

hi, i did a lot of resarch and testing on cell selection and re-selection process the last two week. the cell selection process, network selection process (manual and automatic) and mobility management process were already implemented in OsmocomBB a long time, but turned out to be buggy and incomplete. i made test drives to check the process and debugged it. the re-selection process is new. it is used to track surrounding cells while listening to the BCCH of the current cell (camping on a cell). special extension to the layer1 firmare is used to measure neighbour cells. if an neighbour cell becomes 'better', the mobile switches to that cell, depening on different criteria. now it is possible to move with OsmocomBB. the re-selection process is not handover! handover is a process where a phone switches between cells while doing a call. handover is one next step to implement. the process is a little more complex, because it requires not only neighbour cell measurements, but also syncing to them without interrupting the traffic channel. most layer 3 stuff of handover is already implemented. if you like to play and test your moving OsmocomBB, you can check out the "jolly/roaming" branch. it contains the extension to layer1, as well as sim reader and fixes from "sylvain/testing" branch. use both "mobile" and "layer1" firmware from this branch. in order to see some process at VTY, you can do: enable monitor network 1 (continously display the strongest cell and neighbour cells) show ms 1 (to see current states) show neighbour-cells 1 (to see a more detailed current list of neighbours) andreas

Set fixed TMSI and Kc
by Simian Denson 01 Mar '16

01 Mar '16

Hi, in the osmocom bb mobile.cfg I don't see any posibility to set a fixed Kc encryption key and the tmsi. How could I achieve that osmocom uses my defined Kc and tmsi? cheers, Simian

Location update problems on Motorola C118
by Maciej Grela 13 Nov '14

13 Nov '14

Hi, I'm trying to run the latest osmocom-bb git on a Motorola C118 phone. After a minor problem with the build (as you may've noticed in the patch I've sent). I got to the point of successfuly running layer1 on the phone and the mobile app on the PC (I have also enabled TX). The process seems to be stuck on trying to perform a location update. The status of the ms is always either: show ms MS '1' is up, MM connection active IMEI: 000000000000000 IMEISV: 0000000000000000 IMEI generation: fixed automatic network selection state: A1 trying RPLMN MCC=104 MNC=002 (104, 002) cell selection state: connected mode 1 ARFCN=19 MCC=104 MNC=002 LAC=0xb00f CELLID=0x4fd9 (104, 002) radio ressource layer state: connection pending mobility management layer state: wait for RR connection (location updating) OsmocomBB> or show ms MS '1' is up, service is limited (pending) IMEI: 000000000000000 IMEISV: 0000000000000000 IMEI generation: fixed automatic network selection state: A1 trying RPLMN MCC=104 MNC=002 (104, 002) cell selection state: C3 camped normally ARFCN=19 MCC=104 MNC=002 LAC=0xb00f CELLID=0x4fd9 (104, 002) radio ressource layer state: idle mobility management layer state: MM idle, attempting to update OsmocomBB> I think, that because of this I can't make any calls or send sms (all the requests are being rejected): OsmocomBB# call 1 <X> call 1 <X> OsmocomBB# % (MS 1) % Call has been rejected The log information from mobile when it's trying to do a location update is show below: <000b> gsm48_rr.c:2174 PAGING REQUEST 1 <000b> gsm48_rr.c:2141 IMSI 260021964220249 (not for us) <000b> gsm48_rr.c:2132 TMSI fd82a501 (not for us) <000e> gsm48_mm.c:344 Location update retry <0005> gsm48_mm.c:345 timer T3211 (loc. upd. retry delay) has fired <0005> gsm48_mm.c:4311 (ms 1) Received 'MM_EVENT_TIMEOUT_T3211' event in state MM IDLE, attempting to update <000e> gsm48_mm.c:2199 Perform location update (MCC 104, MNC 002 LAC 0xb00f) <0005> gsm48_mm.c:2333 LOCATION UPDATING REQUEST <0005> gsm48_mm.c:2355 using LAI (mcc 104 mnc 002 lac 0xb00f) <0005> gsm48_mm.c:2363 using TMSI 0x28a3d62e <0005> gsm48_mm.c:914 new state MM IDLE, attempting to update -> wait for RR connection (location updating) <0001> gsm48_rr.c:5428 (ms 1) Message 'RR_EST_REQ' received in state idle (sapi 0) <000e> gsm48_rr.c:1318 Establish radio link due to mobility management request <0003> gsm322.c:4037 (ms 1) Event 'EVENT_LEAVE_IDLE' for Cell selection in state 'C3 camped normally' <0003> gsm322.c:823 new state 'C3 camped normally' -> 'connected mode 1' <0003> gsm322.c:3653 Going to camping (normal) ARFCN 19. <0003> gsm322.c:463 Sync to ARFCN=19 rxlev=-74 (Sysinfo, ccch mode NON-COMB) <0001> gsm48_rr.c:366 new state idle -> connection pending <0001> gsm48_rr.c:1465 CHANNEL REQUEST: 00 (Location Update with NECI) <0003> gsm322.c:2938 Channel synched.

Osmovom-BB on Raspberry Pi
by Richard Menedetter 17 Jun '14

17 Jun '14

Hi All Just wanted to confirm that I got Osmocom-BB up and running on a Raspberry Pi. I did not use the GPIO UART pins but USB <-> serial converters. I tried Motorola C118 and C155 with success. Everything you need is already described: http://bb.osmocom.org/trac/wiki/GnuArmToolchain http://bb.osmocom.org/trac/wiki/libosmocore http://bb.osmocom.org/trac/wiki/Software/GettingStarted?redirectedfrom=Gett… My previous problem seems to have been a not fully compatible crosscompiled toolchain. (it worked mostly, but I could not log-in to a cell and the spectrum view crashed on the RSSI Firmware. Also if you want transmit capability (or flashing) then you need to activate those features in the makefile. Thanks Sylvain (confirming c118 will work) and all others who are involved!! PS: Any news on the "emulated BTS" that has been presented at last years chaos communication congress? I have 2 C118s + 1 normal USB serial dongle + 1 capable of burst ind. I hope this will suffice to also run also a possible future 1 trasmit phone + 1 receive phone configuration. I assume that even without the filter change it should be enough to send a few meters of distance.
