MNCC and MNCC_LCHAN_MODIFY (and ack/nack)
by Holger Hans Peter Freyther 27 Dec '11

27 Dec '11

Hi Andreas, all, right now there is no ack/nack for the MNCC_LCHAN_MODIFY and I would like to introduce _ACK/_NACK for it. The MNCC_LCHAN_MODIFY message will end up calling the gsm0808_assignment_request of the BSC API and in case the call is not on a TCH it will assign a new TCH. Things will go wrong from here. osmo-nitb does not implement the assign_compl/assign_fail callbacks and in case of an assignment failure we crash right now (master has dummy callbacks). I would like to introduce MNCC_LCHAN_MODIFY_ACK/MNCC_LCHAN_MODIFY_NACK, change the mncc_sock.c:mncc_setup_ind and handling of MNCC_CALL_CONF_IND. what do you think? holger

RFC: Osmocom developer workshop 2012
by Harald Welte 15 Dec '11

15 Dec '11

<DISCLAIMER> Please follow-up to openbsc(a)lists.osmocom.org </DISCLAIMER> Hi all, this idea has been around for quite some time, and for 2012 I really want to turn it into reality: I'd like to have a Osmocom developer workshop The idea here is to get all the active contributors of the project together for a couple of days (maybe 2-4 days), in order to exchange ideas, get to know each other better and last but not least work together on ironing out some of the more difficult issues. * City: Regarding the location: I think for me it is only possible to organize it if it is to be held in Berlin. I'mn happy if somebody else wants to host it at some other location, but then that person would also have to take care of local organization. Berlin also has good train and flight connections, which is definitely a plus. * Venue: If it is in Berlin, we might consider talking with c-base or Raumfahrtagentur as possible venues. * Date: Regarding a proposed date, I'm completely open for suggestions. Of course there shouldn't be any overlap with other major FOSS or Sescurity related conferences, and it should also not coincide with major public holidays, as that only makes travel + accomodation more expensive. * Funding: As we don't have that many commercial users of Osmocom projects, getting funding for e.g. travel / accomodation is probably going to be difficult. We can ask the "usual suspects" among those commercial users we know,, but I guess it will only be possible in exceptional cases to provide that kind of funding. Any ideas / comments / feedback is much appreciated. If somebody has a particular suggestion. <DISCLAIMER> Please follow-up to openbsc(a)lists.osmocom.org </DISCLAIMER> Cheers, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

omsosgsn test phone recommendation?
by David A. Burgess 15 Dec '11

15 Dec '11

Hi - Can someone recommend a good smartphone for testing with OsmoSGSN? We are having trouble getting our GPRS modem to recognize a ACTIVATE PDP CONTEXT ACK message and are trying to determine if the error is in the modem, in OmsoSGSN or somewhere in between. Better yet, is there anything out there that can generate an L2 or L3 trace, like the Nokia 3310, but for GPRS as well as GSM? -- David

New tools for (U)SIM authentication
by Harald Welte 07 Dec '11

07 Dec '11

Hi! I've committed the following bits and pieces regarding authentication: 1) libosmocore now has a generic core for authentication algorithm implementations. Using this API, even external plugins can register algorithms which are not available in libosmocore itself. libosmocore includes COMP128v1 and (now) MILENAGE 2) a small command-line program "osmo-auc-gen", which can be used to generate authentication vectors from the command line. You hav to specify all the required parameters. For GSM, this is only ki, but for 3G, you also have to specify at least OPC and SQN. osmo-auc-gen is part of libosmocore.git 3) a small pythong script called "osmo-sim-auth.py", available from a new git repository (http://cgit.osmocom.org/cgit/osmo-sim-auth, git://git.osmocom.org/osmo-sim-auth) It is the counterpart for the MS side. It can execute authentication on both SIM and USIM. I've tested the tools with a COMP128v1 SIM and a MILENAGE USIM, it seems to be working fine.

RFC for VTY documentation
by Holger Hans Peter Freyther 07 Dec '11

07 Dec '11

Hi, my goal is to generate documentation for the VTY, I had a look at quagga but they have a manual process. Right now I have pushed zecke/vty-doc (code + xsd) to libosmocore and a hack to osmo-bsc to invoke it... My plan is to to merge the doc with xslt... and generate some html out of it... For generation I can imagine a new VTY command to dump it to a file or a cli option... comments? feedback? volunteers to make it work and take it from here? holger

Slightly OT: NanoBTS / OpenBSC question
by Tobias Engel 07 Dec '11

07 Dec '11

Hi, does anybody know when the exact moment in a call is, when the NanoBTS starts forwarding audio from a MS to OpenBSC? Is it always when the "Create Connection" RSL message is sent and the TCP connection was established? (Assuming the channel was set up as traffic channel) Or could it be that the BTS waits for the "Connect" message from the MS? I started thinking about that when I saw that the NanoBTS _never_ sets the "transparent to the BTS" bit in the first byte of RSL messages... Regards, -Tobias

GPRS/RLC in Wireshark?
by David A. Burgess 06 Dec '11

06 Dec '11

Hello - [My apologies if this message has appeared more than once; I accidentally mailed it previously from the wrong address.] Is there any easy way to analyze Um GPRS/RLC, encapsulated in GSMTAP at the L1/L2 boundary, in Wireshark? I tried just putting the frames coming into L1 into GSMTAP packets, but Wireshark tries to analyze them as LAPDm. There was nothing obvious in the GSMTAP_TYPE_* values to correspond to Um GPRS/RLC, though I admit that I have not tried other values yet. -- David
