[PATCH] make example config usable
by ☎ 13 Sep '12

Hello. Attached is a trivial patch which makes example config for libosmo-sgsn actually usable. Most likely it was typo. -- best regards, Max, http://fairwaves.ru

Introducing libosmosim
by Harald Welte 12 Sep '12

12 Sep '12

Hi! I've been hacking away a bit on a new library 'libosmosim' whihc is scheduled to become part of libosmocore. In fact, as the automake integration has been cleaned up, I'll probably merge it master any day now. The idea of this library is to * understand the EF/DF hierarchy if GSM SIM, ETSI UICC and 3GPP USIM * provide encoding and decoding routines for at least the most important EFs * decode the binary data into a generic data structure which can be used by some form of a GUI application * be able to re-encode from the generic parsed structure into the binary form, possibly after modification from the UI * be able to transact APDUs via T0 and T1 on PC/SC and other reader interfaces, e.g. the OsmocomBB SIM interface So the primary purpose of this is to be able to have a tool for meaningful (human-readable/writable) modification of all files on a programmable SIM card, such as the sysmoSIM-GR1 (and other cards where you have the ADM PIN that gives you write permission). Other useful purposes on the horizon of the library could be: * implementation of a generic SIM/UICC/USIM simulator based on user-created input, or based on 'ripped' SIM cards (well, you have to provide the key in some way). The current status is still quite experimental, but you can already see the major parts: * mapping of APDU and TPDU (only T=0 so far) on to 'struct msgb struct osim_file_ops encode and decode callbacks for a given file struct osim_file_desc node in the hierarchical description of filesystem tree struct osim_decoded_data the runtime representation of a decoded file: struct osim_decoded_element one decoded element in a decoded file struct osim_card_sw status + bitmask + human readable description struct osim_card_profile full description profile of card, including filesystem hierarchy, status words and card-specific commands struc osim_reader_hdl represents a card reader (currently a slot in a reader, not sure really how to represent multi-slot readers like sim-banks yet). primarily consist of osim_reader_ops struc osim_card_hdl representing a card inside a reader struc osim_chan_hdl currently just a dummy. intended for logical channel support most of the existing code is in src/sim/*.c, while some not-yet-cleaned-up example code is in utils/osmo-sim-test.c. There are gaps everywhere all over the place, and I think it will take quite some time to fill those gaps. Current roadmap: * properly integrate all parts, so with a single call you can read in the tree of all EFs of a card into their in-memory representation * verify that the APIs for encoding/decoding functions work the way they are before writing 'all' the EF decode/encode routines * add more decoded element types, such as location area codes and the like So if you survived this mail until this point, I think you are a prime candidate for contributing some code. Let me know if you're interested in helping out.

MultiARFCN OpeBSC and SysmoBTS
by Daud Suleiman 10 Sep '12

10 Sep '12

Hi Harald, I can't tire of congratulating and the community for the great work you are doing in creating a free world in your own capacity! I thank you. Meanwhile, I would like to know a few things: 1. Is sysmoBTS capable of operating in MultiARFCN? Is multiARFCN implemented in OpenBSC and if so how does one go about configuring it. 2. Also after the successful implementation of CSD, are there plans for PTT over Cellular (PoC)?

by Harald Welte 05 Sep '12

05 Sep '12

Hi all! This is the announcement for the next Osmocom Berlin meeting. Sept 05, 8pm @ CCC Berlin, Marienstr. 11, 10113 Berlin There is no formal presentation scheduled for this meeting. If you are interested to show up, feel free to do so. There is no registration required. The meeting is free as in "free beer", despite no actual free beer being around. Regards, Harald [p.s.: I myself will not be able to attend tonight, but I'm sure you will be able to do just fine (or even better?)] -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
