May 2012 - OpenBSC - lists.osmocom.org

by Peter Caprioli

Hello everyone, I've just finnished writing together a small web interface for the OpenBSC HLR. It allows you to modify various parameters in the database and also provides a set of functions to modify the HLR or sending SMSes in your own scripts. The project is still very alpha but it seems to work reasonably good. Feel free to give any feedback! Screenshots and source code is available on my website: https://stormhub.org/simplehlr/ -- *Best regards, Peter Caprioli*

Several questions

by jason mercury

I have some questions: 1) When I start bsc_hack bsc_init.c first establishes OML link and initializes the bts then it establishes RSL link and bts starts broadcasting. However, it takes so much time to start the bts. Instead of this I want to do the following: it establishes OML link at the beginning and only once, then when i want to start broadcasting it establishes just the RSL link and bts will start faster since i don't have to wait for OML link. What should be done for this? 2) If i send one or two word messages from telnet interface it is okay. But if i send a longer message the phone could't receive the end of the message correctly(last words may be incomplete). Did any one encounter with this problem? What is wrong with me? 3) Could I send SMS in which extension of the sender is text not integer. For example, i want to send an information SMS that this is a test network. For this purpose i want to send an SMS from 'OpenBSC'. I set the extension of the first subscriber in database as text and tried to send the SMS but SMS wasn't delivered. What should i do? 4) Can i add SMS externally to SMS table of database? Thanks. Jason

OpenBSC with Dahdi+Asterisk and several BTS

by Ellen Apolinar

Hey folks, I am new with OpenBSC and want to build OpenBSC with several BTS from different types. At first what I need: I want to test OpenBSC without a BTS just to see if the installation worked successfully. Also I need to know what I have to do if I want to use a BTS which isn't configured yet. What we want to do in the end is to test the BTS with a selfmade programm. For this we need an interface between the hardware BTS and the pc. What I have: Ubuntu 11.10 Kernel 3.0.22 several BTS (Siemens BS60/BS240, Nokia Citytalk, Alcatel G9100 etc...) HFC-E1 card from Cologne Chip OpenBSC Asterisk 1.8.4.4 + Web-GUI (Asterisk NOW 2.0) Dahdi 2.4.1 Libpri 1.4 mISDN v2.x mISDNuser 2.0.11 LCR 1.7 Twinkle, Wireshark etc. Why mISDN + Dahdi: First I tried to use mISDn + mISDNuser + LCR for a connection between OpenBSC and Asterisk. mISDN was integrated in the Kernel so I thought it's the best idea to use it. I installed mISDNuser and LCR but there are several problems. For further informations you can have a look here: http://www.ip-phone-forum.de/showthread.php?t=247932 Because of the problems mit LCR/chan_LCR and Asterisk I decided to use Dahdi because it's also installed since I installed Asterisk. Asterisks works fine with the softphones which I created with Twinkle and also the Asterisk GUI works without problems. To use Dahdi: modprobe -r hfcmulti modprobe -r mISDN_core /etc/init.d/dahdi restart /etc/dahdi/system.conf: dchan=1 bchan=2-30 openbsc.cfg: e1_input e1_line 0 driver dahdi To start OpenBSC: cd /etc/openbsc/src/osmo-nitb ./osmo-nitb Error: <0005> bsc_init.c:493 Failed to parse the config file: 'openbsc.cfg' So now I'm not sure what to do because I'm not sure what exactly is wrong and if it could work without a BTS. There are enough informations if I want to test a BS11 or a nanoBTS but I'm a little bit lost how to work with another BTS. In the next day I will get the traces from the several BTS to build an interface between BTS and OpenBSC so I can build the openbsc.cfg-file. But it would be great if it is possible to test OpenBSC before I get the traces. To get a connection between OpenBSC and Astrisk with Dahdi is a problem which I should solve by myself. There should be enough information in the internet. if you have questions or need more informations just write an e-mail. Best regards and thanks in advance. It would be great if someone could help me or give me some advice what I could do. Ellen

LCR compilation problem

by Arturo Rivas

Hi! I'm trying to install OpenBSC+LCR. I'm following the next tutorial: http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR I have installed libosmocore and openbsc but I can't install lcr. I tried to apply patch from tutorial but it doesn't works, maybe version is so old because gsm_bs.cpp is not the same. When run configure terminal shows: configure: error: in '/home/rivas/OpenBSC/lcr' configure: error: --with-asterisk was given, but test for header-file asterisk/compiler.h failed I have new Ubuntu 12.04 and I have install asterisk from apt-get repository. Someone can help me? Also I need to know if there is a tutorial recently actualized. Best regards, Arturo Rivas.

First version of Erlang based telnet server

by M. Josenhans

Hello, while there there is a comandline interface for openbsc to configure the BSC software, until now there has been nothing comparable as user interface for the osmocom/Erlang code. This has changed. Here is a first version of an Erlang written command-line interface: https://github.com/josemic/Erlang-command-line-interface Be aware that there is currently only dummy data presented. It has not yet been integrated with the osmocom/Erlang code. Please test and provide feedback. For installation instructions please see github wiki pages. Br, Michael

sim

by Hans Witvliet

Hi all, Perhaps i am completely mistaken.. If so, please make it a "learning-moment" for me ;-) Is it possible to crate your own SIM's ? As far as i can see, these are just small smartcards. And as such, thse can be filled with the tools that come along with OpenSC. I presume the SIM's contain a number of EF's and DF's One set that thighs a SIM to a specific operator (making it possible to SIM-lock a handy) And another set of EF's that identifies a specific user. Within the DB of the operator, the relation between the SIM-identifier and the specific user (with his 06-number and other info) is made. (I know that the sim itself is not unique, because a college had a malfuntioning SIM, and it was replaced by another one, with the same content) Reason why i want to fill my own sims is this; For one of our projects we are using certificates on a smartcard. Currently full-sized, but we think of putting it on a sim-sized card. And use it in a dongle along with 2Gb (bootable) flash storage. So my questions are: 1) can you burn your own sim's 2) would there be any objections to have, beside de GSM-info, also a certificate 3) could you "clone" an existing SIM? With regard to the last one: If i buy a couple of prepaid-sims from a operator, would it be possible to extract that info, and put it along with my own certificates on a sim of my own? Obviously, it is no use to contact the help desks of kpn, tele2, or vodafone at this moment. But _if_ their are no technical limitations i could do a test with some of our own BTS'es. And if that pilot works, we have a business case for any interested operator. Hans

pySIM patch for USIM

by Dragos Vingarzan

Hello Silvain, please find attached a patch for pySIM which I put together today after some work to get the extra parameters which I needed on the sysmoUSIM-GR1. Don't know if it only works for those cards. This fixes some bugs in setting the IMSI and also adds support for selecting USIM and writing binary/records in there. I have also added some parameters like MSISDN or the forbidden MCC to black-list other national networks, in the idea that one would provision on the test 001/01 network. The data formats are not so well defined or clean as I was on a get-it-done schedule and did not actually read the specs. Anyway, the result works fine for me. Otherwise I could only use pySIM with the GemPC Express reader. I read that you have a PC Twin Reader which seems to be more common, but I am getting the following with that, so any help would be appreciated: Programming ... Traceback (most recent call last): File "./pySim-prog.py", line 544, in <module> card.program(cp) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/cards.py", line 364, in program data, sw = self._scc._tp.send_apdu_checksw("0099000033" + par) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/__init__.py", line 88, in send_apdu_checksw rv = self.send_apdu(pdu) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/__init__.py", line 69, in send_apdu data, sw = self.send_apdu_raw(pdu) File "/root/svn/svnsrv.fokus.fraunhofer.de_OpenEPC/pysim/pySim/transport/pcsc.py", line 75, in send_apdu_raw data, sw1, sw2 = self._con.transmit(apdu) File "/usr/lib/python2.7/dist-packages/smartcard/CardConnectionDecorator.py", line 82, in transmit return self.component.transmit(bytes, protocol) File "/usr/lib/python2.7/dist-packages/smartcard/CardConnection.py", line 140, in transmit data, sw1, sw2 = self.doTransmit(bytes, protocol) File "/usr/lib/python2.7/dist-packages/smartcard/pcsc/PCSCCardConnection.py", line 175, in doTransmit raise CardConnectionException('Failed to transmit with protocol ' + dictProtocolHeader[pcscprotocolheader] + '.

OpenBSC "success stories", anyone ?

by Harald Welte

Hi all! We sometimes get media inquiries about where (and for what) OpenBSC is actually deployed. Like any Free Software project, we of course have no clue how many users there are, and what they do with it. There are some companies that we know of, as we've received their patches, or actually did some consulting for them as part of our paid work. Some of them are actually listed in the source code and/or on our homepage. However, I would like to see more than those "usual suspects". So if you use OpenBSC for anything beyond your personal hobby, I would like to hear from you. If possible, I would like to anything from a small one-line statement to a multi-paragraph explanation about it on our project webpage. It doesn't have to be all-positive. You can even state that you tried it but didn't get So far, I know there are * at least one handful of academic institutions using it for research and/or teaching * at least one company that's using OpenBSC based networks as communications technology at large events (concerts/festivals and the like) * at least one company operating OpenBSC on board of maritime vessels * at least one company building systems for desaster / emergency relief based on OpenBSC So if all of you (or at least some of you) could step forward and send me a notice (either privately or Cc to this list), I would appreciate it a lot. Regards, Harald p.s.: And yes, I'm talking about the OpenBSC homepage, not the sysmocom company page. We keep a strict separation between those two, and if you ever think that we might not follow that clear distinction. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

nanoBTS

by Stuart Baggs

Hello All I know the list isn't for advertising but I thought some of the list members trying to source a nanoBTS may find this useful. We currently have 2 model 139 1800 MHz units here in our office which we pulled from a live GSM network earlier in the week. We've got them working with openBSC just fine. If anyone is interested please give me an email. P.S. We've sold quite a few of these to list members before so referencing isn't a problem. Kind Regards Stuart

Re: Sagem OT-290 trace phone / GSMTAP integration

by Tyson Key

Hi list, It's my first time posting here, and I've just subscribed - so apologies for totally wrecking archive threading. I've just received a copy of the e-mail regarding the OT-290, thanks to Andrew Back; and I'm wondering it's possible to discuss the feasibility of implementing this functionality with Harald - since it doesn't seem to have generated much interest from others, and I'm "fortunate" enough to live in a small British town without EDGE coverage (which should make it easier to test GPRS-related tracing functionality). Although I'm unfamiliar with how things work in Osmocom, I've previously worked on Wireshark dissectors for USB-encapsulated AT commands, and various NFC/smartcard-related protocols (PN532, FeliCa and MiFare); and am also familiar with Nokia's proprietary ISI baseband protocol, and parts of ETSI's GSM/UMTS specifications - so this sort of stuff isn't totally alien to me. I'm also currently studying Computer Science as an undergraduate (at the University of Bradford) - but I should be able to make time to work on this.

Bugreport Openbsc Authentification

by Robert Ingr

Hi all, as we were running openbsc with a nanobts in a nitb configuration at our institute we observed two bugs in the authentification part of openbsc. First: In file openbsc/openbsc/src/libmsc/db.c on line 372 there is "ainfo->a3a8_ki_len = sizeof(ainfo->a3a8_ki_len);" which takes the sizeof of the length value. This always results in a wrong keylength and hence no authentification will ever be executed. This should rather be changed to: ainfo->a3a8_ki_len = sizeof(ainfo->a3a8_ki); Secondly: I haven't found the piece of code which is responsible for this bug particulary but: Whenever the key for the a3a8_comp128 is being read from the database a shift of one bit occurs. i.e. when you set the a3a8_key in the hlr.sqlite3 to 01010101010101010101010101010101 the value being processed as key in the a3a8_comp128 algorithm is 02020202020202020202020202020202.

Possible solution to ticket #55

by Frank Maas

As reported in ticket #55 SGSN can crash due to double free-ing. You can replace 'can' by 'will' in that last phrase. I had a sift through the code and tried to solve this by removing the free in gprs_ns.c. Whenever the calling function created the msgb-struct, I have made the function free it after its use. If the function got the msgb from a calling function, there will not be a free (hoping that will be done on the higher level). HTH/F

Sagem OT-290 trace phone / GSMTAP integration

by Harald Welte

Hi all! Thanks to a generous donor, we have received a couple of OT-290 trace phones. These are commercial products intended for taking L2/L3 air interface traces. If you've read any of the fabulous GSM papers by Prof. Dr.-Ing. Joachim Goeller: The OT-phones is what he used to generate all his traces. The majority of what those phones can do is now also possible with OsmocomBB. However, OT-290 support GPRS tracing/testing - for CS-1 throguh CS-4. I would be willing to give away one of the two remaining OT-290 (for free) to anyone who would in return commit to developing a GSMTAP interface for it. The message format on the serial UART between phone and PC is documented (PDF documentation by Sagem included with the phones). So based on this documentation and an OT-290 phone, it should be possible to write a small command-line program that receives the GSM/GPRS messages from the OT-290 and sends them via GSMTAP into wireshark. The result would then be similar to what http://cgit.osmocom.org/cgit/dct3-gsmtap/ is for DCT-3 phones. If you're interested, please respond to this message. Please don't apply for the phone if you are not able to find the required time and interest for actually doing the GSMTAP integration.

However, these retransmissions are characteristical for all Nokia devices I've tested so far (6021, C5, C7, E65, 3109c). Is there a timing problem between osmo-sgsn and Nokia devices? Can I tune osmo-sgsn's parameters to make the connection work? Any help would be appreciated. cheers Olaf ---------------------------------------- -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de

SIM Card Sources

by Duncan Smith

Hello, Does anyone have recommendations for obtaining SIM cards? I'm trying to get at least 500, unprinted and unprogrammed. Ideally, I'd be able to buy 1,000 (or more) cards for around USD$1,000 total, but I'd be willing to go up to 5,000 cards if the price drops to something like USD$0.50 per card.
