OpenBSC "success stories", anyone ?
by Harald Welte 21 May '12

21 May '12

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."

Query ragrding libosmocore installation
by Manan Bhatt 19 May '12

19 May '12

Sir, I am working on a project to implement a GSM test-bed scenario. I need do install openBSC. I go through your page indicating the installation guide. My problem is git clone is not working.Everytime it is telling that the server is not responding. When i tried to install using tarballs the version conflict is coming in case of libosmo-abis and openbsc as the tarballs are provided of different versions. libosmocore 0.1.30 but libosmo-abis needs libosmocore >=0.3.0 . Please help me regarding this. -- Regards, Manan Bhatt

nanoBTS
by Stuart Baggs 18 May '12

18 May '12

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

OpenMSC (OpenBSC without BSC) talking SIGTRAN (M3UA).
by Henrik Aagaard Sørensen 09 May '12

Are there any work being done or already implemented solutions towards having OpenBSC work without the BSC-part and having the MSC-part talking SIGTRAN (M3UA)? All help is very much appreciated. Regards, Henrik

Re: Sagem OT-290 trace phone / GSMTAP integration
by Tyson Key 08 May '12

08 May '12

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. Thanks, Tyson. -- Fight Internet Censorship! http://www.eff.org http://vmlemon.wordpress.com | Twitter/FriendFeed/Skype: vmlemon | 00447934365844

Bugreport Openbsc Authentification
by Robert Ingr 08 May '12

08 May '12

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. Best Regards, Robert Ingr

Possible solution to ticket #55
by Frank Maas 07 May '12

07 May '12

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
