Re: Help with sccp library

I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

Re: Any interest for Osmocom meetings in Bavaria ?
by Dieter Spaar 11 Jun '13

11 Jun '13

So far three persons have indicated their interest to join a meeting at my place. Considering the time it takes to drive to my place, it probably makes sense to have the meeting at the weekend (either Saturday or Sunday) so that there is more time for the meeting itself. I can suggest one of the following dates for the first meeting, somewhere between 10:00 to 18:00 on each day: 25.8. (Sa) or 26.8. (Su) 1.9. (Sa) or 2.9. (Su) 8.9. (Sa) or 9.9. (Su) So please let me know when you have time and also make suggestions in which Osmocom topic you are interested in so that we can have some sort of agenda for the meeting to make best use of the time. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

SimpleHLR: A web interface for OpenBSC
by Peter Caprioli 03 Jun '13

03 Jun '13

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*

OpenBSC with LCR/SIP
by Kelum Navaratne 26 Jan '13

26 Jan '13

Hello list, First of all congratulation to developers of this project making such wonderful project in an interesting subject. I am new to this project and for past few days i managed to go through the documentation and get most of it tested. Thanks for pretty good documentation in most of the areas as well. I have the osmo-nitb working very fine using a nano bts. How ever when i try to install it with LCR to interconnect with external switch, im facing some problems. Initially i thought i must use LCR+Asterisk. But later i figured out there is a built in SIP interface on LCR which there is no need to asterisk or chan_asterisk. I would prefer to use this LCR SIP interface as i dont want to use asterisk and just want to forward all calls to another SIP switch. Now in this context there seems absolutely no documentation on both openbsc and LCR/mISDN lists. Can some one please shed me some light here on how to build a LCR with SIP to be work with osmo-nitb. All i want to test is GSM phone > Osmo-nitb > LCR with SIP > SIP softswitch Thank you very much for every one's effort in this project and would be glad to see some response for this. Best Regards Nava.

osmo_sock_init/getaddrinfo not working for GRE/SOCKET_RAW
by Holger Hans Peter Freyther 14 Jan '13

14 Jan '13

Dear Pablo, getaddrinfo does not work for the combination of AF_INET, SOCK_RAW and IPPROTO_GRE. I have attached an example application that can be compiled with: $ gcc -o fr fr.c `pkg-config --cflags --libs libosmocore libosmogb` this prints: getaddrinfo returned NULL: Success FAILED gettadrinfo returns -8 which should be this: # define EAI_SERVICE -8 /* SERVICE not supported for `ai_socktype'. */ I am not sure what is the most clever way to resolve this. Make SOCK_RAW branch out early and do the socket/bind(/listen) manually, use getaddrinfo twice with some more unspefici options, just deal with SOCK_RAW differently now? The attached code has the benefit of at least handling INET and INET6 inside the getaddrinfo result. any ideas? holger

triplets calculation
by Yann R. Moupinda 04 Jan '13

04 Jan '13

Hi guys, i'm still testing the eap-sim authentication and lately i got acceptable results using a simple flat file containing the triplets of specific SIM cards. Next step will be to enable the external radius server to use the sysmoBTS database hlr.sqlite3, so the OpenBSC users (Users using the OpenBSC-GSM Network) can automatically access to the internet. i just want to ask if there are any limitations with the sysmocom SIM cards? In fact, i noticed that by using the sysmocom sim cards, the eap-sim authentication failed when the RAND values strong randomly chosen were, e.g 046DBA898016454aB3920C58180DA2F5 or e177842fe16c47de84784be1b4141c27. But when i chose a RAND like this 10101010101010101010101010101010, 0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F or 00000000000000000000000000000000, the authentication succeeded. By using an other sim (not from sysmocom) with the same strong and weak RAND values the authentication always succeeded. Why does the authentication succeed buy using sysmocom sim card with weak RAND (10101010101010101010101010101010) and fail by using strong RAND values (e177842fe16c47de84784be1b4141c27) ? best regards Yann

OsmoDevCon 2013 brainstorming
by Harald Welte 04 Jan '13

04 Jan '13

Hi all, as the year 2012 has already ended or will soon end depending on your timezone, it might be a good occasion to start thinking of an OsmoDevCon 2013. I personally percevied OsmoDevCon 2012 as a big success, and it was fun to bring everyone together. Generally, I prefer to keep the spirit of an invitation-only developer+contributor-only event of those involved in Osmocom. At the same time, I would consider it a good idea to add a one day user-conference to the schedule, where we try to get interested users up to speed with the various projects, possibly including some workshops and the like. So schedule-wise, I would suggest something like: * one day user conference * two day developer/contributor event * optionally: 1-2 "hacking days". The concept of "hacking days" has proven to be quite useful for the netfilter project in the past (Pablo and I can acknowledge to that fact). I'm not sure how many people would be able to spend even more days of their schedule, but even if it's a much smaller group it would still be useful, IMHO. I'd like you to 1) provide feedback on the ideas about the one-day user event and the hacking days 2) consider whether late march (like 2012) would be a good schedule again 3) what we can improve from the last event In terms of improvements, I so far have noted down: * larger venue needs to be found * complaints about the venue not having sufficient heating Venue-wise, I would again suggest to hold it in Berlin, as it's reasonbly well connected, has lots of low-cost flights to it, accomodation is not too expensive and holger/me/sysmocom can take care of local organization related activities. Hoewver, if somebody has a strong opinion against berlin _and_ is willing to organize it, I'm not completely against another venue.
