DFU mode, wireshark
by Martin Kaiser 12 Jan '14

12 Jan '14

Dear all, recently, we added a dissector for USB DFU to wireshark. It recognizes packets based on product ID + vendor ID. I tested this with my simtrace (v1.0) board and it works like a charm when I add 0x16c0, 0x0762. However, I saw that for the simtrace board, prod id/vendor id is the same for DFU mode and sniffer mode. I guess that for sniffer mode (or any other mode than DFU), it doesn't really make sense to capture the raw USB packets. Therefore, I tend to add 0x16c0, 0x0762 and link it to USB DFU. Are you ok with this? Thanks, Martin

OsmoDevCon 2014 / Date / Venue
by Harald Welte 01 Jan '14

01 Jan '14

Hi all, time is moving fast, and I want to start some initial discussion and planning for OsmoDevCon 2014. There are basically four questions which I'm raising below. Please provide your feedback to the osmocom-event-orga mailing list only, to avoid cross-posting over all the project lists. = Who? = My intention is to keep it an 'active developer/contributer only' event, like we had it before. I would also want to keep the group relatively small, to keep the 'Osmocom family' atmosphere. If desired, we could have one half or full day of public prsentations in a larger auditorium, but the developer meeting should be a close group, as known so far. = Where? = If we keep the number of attendees within the same range as this year, then I'm sure we could again hold it at the same venue. I know it is not perfect, but it is a place that we have access to, 24 hours per day, and free of cost for community projects like osmocom.org. If the community wants a larger event, then this is something that would require more funds and much more time organizing. And that is something that I personally could not offer to take care of, sorry. I'm happy to attend and support any larger events, but I'm unable to take care of fundraising and venue research. = When? = Q1/2014. In January, I'm not aware of any 'blocker' events. February, there is Fosdem (Feb 1 + Feb 2), and MWC from Feb 24 through Feb 27. In March there is CeBIT (March 10-14) and Easter holidays (with EasterHegg March 17-21). Did I miss any other FOSS / mobile event that might clash in Q1? So my preference woudl be to do it either late January (23-26) or in February (6-9 or 13-16). Any preferences regarding preferred schedule? Once we have some concencus here on the list [and we want to do it in the same size / venue], I'll talk to IN-Berlin. = What? = I think that question is easy to answer, if we have the above three figured out... There's no shortage of topics, I suppose. You can start adding your suggestions to http://openbsc.osmocom.org/trac/wiki/OsmoDevCon2014 Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

3FF Probe - using dual sim card adapter
by Dean Chester 07 Dec '13

07 Dec '13

Hi, I saw in an earlier post that tsaitgaist recommeneded dual sim card adapters for using as probes has anyone had any success with these and cutting the correct lines if so which lines do I need to cut in order to use this as a probe? What instructions should I follow so that I can trace my sim card. I'm using this as another solution as I have had no success using the 3FF probe in my iPhone 4s for tracing. Kind Regards, Dean Chester

SIMTrace Host Software in Python
by Dean Chester 20 Nov '13

20 Nov '13

Hi, I've been working on developing the host software in python to make it cross platform, its still in the early stages at the moment. Its available here: https://github.com/deanchester/simtrace This is my first ever open source project, feedback would be good. Its still in the early stages of development but I hope people will in time start to use it. Kind Regards, Dean Chester

Osmocom CardOS project gets its own list
by Harald Welte 15 Nov '13

15 Nov '13

Dear all, in recent weeks several people have contacted me that they would be interested in attempting to bring the idea of a CardOS forward. To provide them a place where they can share ideas and code, I have created the osmocom-cos(a)lists.osmocom.org mailing list. So anyone interested in this development: Please feel free to subscribe that new list: http://lists.osmocom.org/mailman/listinfo/osmocom-cos Regards, -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

SIMtrace 3FF / micro-SIM adapter available
by Harald Welte 18 Oct '13

18 Oct '13

Hi! I really don't want to feel this list to be abused for advertisements, but in this case I'm sure it is of actual help to a number of people on this list: The sysmocom web shop finally has a 3FF (micro-SIM) adapter cable available: http://shop.sysmocom.de/products/simtrace-fpc-3ff Please note that (as opposed to the regular mini-SIM) we only have one of the possible four orientations available. This is primarily due to the high manufacturing cost of low-volume flexible PCB projects. We would like to hear from you 1) if you need this adapter in different orientation (which, for which phone) 2) for which phone model you have used this new 3FF adapter successfully 3) what kind of problems you may have encountered using it. Thanks to Kevin Redon for doing the PCB layout of this part. It is freely available as part of the simtrace.git repository since commit eee3243ddaa9e13bc7509a962fade8636b6ed2ab. On a related note: For nanoSIM, I think we would have to go for dual-layer PCB with vias placed inside the actual card contact pads. This will make production cost even more expensive than the microSIM adapter. So unless there's significant interest in a nanoSIM adapter, it's unlikely that we'd have some made. Please let us know if you absolutely want one, and if you're happy to pay even more (e.g. 25-30 EUR) for only that adapter.

possible PPS error
by Kevin Redon 09 Oct '13

09 Oct '13

Hi, I just got a SIM card which can not be detected by the phone when having simtrace in the middle. The phone is a Samsung Galaxy SIII, simtrace v1.2p, with current firmware. The SIM card works when plugged in the phone directly, and SIMtrace with this phone work with other SIM cards. This SIM cards allows high transfer rates, and the phone tries to do the PPS exchange, but somehow fails and the tells no SIM card is detected.

Does anyone have a Terminal Profile handy for an iPhone 4 or 4S? I dont' have the microSIM SimTrace adapter, and the database here: https://terminal-profile.osmocom.org/ doesn't appear to have been updated in a while. Thanks!

MITM voltage fix using ATR
by Tom Schouten 10 Sep '13

10 Sep '13

Hi List, When using MITM it is possible to set the SIMtrace<->phone voltage levels using ATR, giving a clear-cut way to solve the incorrect I/O level problem: See byte TA(3) C7->C2 orig ATR from card: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC78031E073FE2113574A33… modded to select only 3V: http://smartcard-atr.appspot.com/parse?ATR=3B9F95801FC28031E073FE2113574A33… Cheers, Tom

INS=STATUS + car reset question
by Tom Schouten 05 Sep '13

05 Sep '13

Hi List, I'm running into the following command sequence in a Nexus One Android 2.3 phone: C-APDU:80F20001FF (STATUS) R-APDU:6C12 (Incorrect Parameter P3) After which the phone power-cycles the card. I'm wondering whether this is is desired behavior, or if it's a bug in the new MITM code. Phone seems to reset the card quite often when in USIM mode. Running the card in SIM mode, this doesn't happen. Cheers Tom
