detecting TMSI and Bursts relation?
by Simian Denson 08 Apr '12

08 Apr '12

Hi, is it technically possible to sniff the air traffic (for example with ccch_scan from the osmocombb burst_ind branch) and correlate the relationship between a burst and a paging request (which contains the tmsi of the mobile) ? Basically: What are the steps to determine which tmsi (mobile) did which burst ? Thank you for your information! cheers, Simian

Reliablility problem in current git?
by Tim Ehlers 04 Apr '12

04 Apr '12

Hi, I have a git clone from 23.01.2012 and a current git clone. When I compile both and use the mobile appliation, I have a strange problem in the current code. Very often I can't send USSD codes (and maybe also can't communicate in other ways; USSD is the costless way to check whether I am connected or not). Ok, this is what I do: I send "service 1 *#21#", wait the answer and the string "% On Network, normal service: Germany, O2". Then send it again and so on. With the old code, I reliable get the answer e.g. "% Status: deactivated". With the new code, I very often (sometime already when trying first time) get nothing back and after some seconds only "% Service connection terminated.". Can someone confirm this behavior? Thanks Tim

Basic build problem.
by Andrew Back 04 Apr '12

04 Apr '12

Hello, I'm experiencing problems getting started with building BB and wondered if someone might be able to advise. Seems that whenever I specify a toolchain prefix it is ignored. E.g. $make -e CROSS_TOOL_PREFIX=arm-none-linux-gnueabi- Results in an error: "configure: error: in `/home/andrew/Work/AB Open/Projects/GSM/Osmocom/osmocom-bb/src/shared/libosmocore/build-target': configure: error: C compiler cannot create executables See `config.log' for more details" If I check ./shared/libosmocore/build-target/config.log for instances of "arm" these are all still "arm-none-eabi", which I do not have. The prefix example above was to attempt to use CodeSourcery Lite tools. I've also tried with a prefix of "arm-linux-gnueabi-" to use a toolchain installed from Emdebian via apt-get, and I experience the same problem. Although in searching for a fix I read something which suggested that the Emdebian toolchains may be no use. So, am I doing something wrong in the first step? And is there perhaps another toolchain I should be using? Apologies if this has already been answered — I have done a bit of searching but only found similar errors where a prefix was not being specified.

Re: Recording / Re: Regular Osmocom meeting in Berlin?

It was my understanding from your suggestion that there would be presentations and discussions after those presentations at the meetings, making this not just having a beer with friends but more formal affairs. That would be useful for people elsewhere to see, given that this is a global community. Not sure what German law has to do with putting online or streaming such presentations. Cameras off when it comes to the informal part and beer time.. Love this list otherwise. And will come to Berlin this summer so may attend one or two, regardless :) Cheers from New York.

The mere existance of the two words 'camera' and 'unobtrusive' in one sentence are a contradiction in terms. If I want to meet with a small group of people and informally discuss technical topic, than that is _very_ different from being live streamed to an unknonwn number of people, any of which could make recordings and I would have to very carefully think about each and every word that I'm saying. That's not a particularly relaxed environment and would kill all the fun there is in having the meeting in the first place. Legally, In Germany this corresponds to "not publicly spoken word" (nicht oeffentlich gesprochenes Wort). It is punishable under law to record or broadcast that. (Clause 201 of German criminal code).

Could not disagree more. We live-stream local events all the time with a very unobtrusive webcam/ustream and it bothers no one who is there but benefits all who are not.

It kills the local atmosphere without having any real benefit. Every decision/code and most likely slides will be public anyway. z. Sent via mobile. Hence, short.

Regular Osmocom meeting in Berlin?
by Harald Welte 31 Mar '12

31 Mar '12

Hi all, I was pondering to start a regular Osmocom meeting (monthly or bi-weekly) in Berlin. The idea would be not only to converge the existing developers in Berlin (zecke, roh, prom, tobias, peter, kevin, myself, ...) but to also try to share some knowledge and excitement with other interested hackers in the wider community. A split format for the event might make sense: Have a more or less organized 45min talk about one particular topic + 15min discussion and then switch to an informal meeting style without any particular topic or moderator. For the first half there is a long list of topics intended at informing people about the status and capabilities of the respective projects: OsmocomBB, OsmoTETRA, OsmoGMR, SIMtrace, etc. Regarding the venue, I would suggest to hold it at the Berlin CCC. What do you generally think about this? What day of the week should we be aiming at? Tuesday and Thursday is generally not a good idea, as those are already occupied with other events. If you think it's a good idea, I would request/register the event with the CCC Berlin.
