libosmo-sccp and static archives
by Diego Elio Pettenò 12 Aug '12

12 Aug '12

Hello, I was going on with the autotools cleanup (in order of listing in cgit) but I'm a bit surprised about the libosmo-sccp structure, which contrarily to libosmocore, libosmo-abis and libosmo-dsp is not using libtool, but it's actually building three static archives, with one source file each. Now, I don't know if it might be too late to consider changing this but I'm wondering why it has been done this way; when using a shared object it might make sense (although the overhead of using more than one object is probably higher than loading the unused code), but with static archives all the Unix link editors I know only take by default only the objects that are actually needed by what it's being linked; that is using a single libosmo-sccp.a will only bring in the final linking the object files that are actually needed. I also wonder if it wouldn't make more sense to have everything built in the same project/source tree with libosmocore — in general this seems to be small enough, and the time/space spent for these three files is probably well recovered by the extra ./configure run that it has to run. Let me know if I can be of help — I'll still send the autotools cleanup for this project today I think. -- Diego Elio Pettenò — Flameeyes flameeyes(a)flameeyes.eu — http://blog.flameeyes.eu/

Re: Any interest for Osmocom meetings in Bavaria ?

I have very tight travel schedule in the next months. Just to avoid any misunderstanding: Those meetings are not supposed to be something similar to the Osmocom Developer Conference earlier this year. The idea is to have a regular or "on demand" oportunity to meet with people for a few hours and demonstrate or talk about the Osmocom projects or share new ideas. Its comparable to the regular Berlin meetings, you can get an idea of what goes on there: http://openbsc.osmocom.org/trac/blog/osmug-20120808 Of course you can attend, if you are close (Munich airport is 120 km away) but I would expect that Berlin is more convenient if you come from really far away and Berlin already has regular meetings.

As a quick follow up: The proposal for the meeting is intended for everyone interested in the various Osmocom projects (e.g. OpenBSC, OsmocomBB, TETRA, SimTrace, OsmoSDR). The meeting is not limited to only those who are actively participating. I will wait until next week to see how many people are interested, so far I am aware of two persons.

Any interest for Osmocom meetings in Bavaria ?
by Dieter Spaar 07 Aug '12

07 Aug '12

I would like to ask if there is interest to have some kind of Osmocom meetings in Bavaria. Suggested location is here at my place in the south-east of Bavaria near Pfarrkirchen. There are no large cities close, but the location is still in reach with a car, some examples (single distance): - from Munich: 130 km - from Passau: 55 km - from Salzburg: 90 km - from Linz: 140 km Why at my place ? There is some GSM/3G/TETRA equipment and RF measurement gear around which could be demonstrated. It is not yet decided when and how (regular or "on demand") this meeting should take place. Before that I want to find out if there is interest at all and how many people are interested. So please write to the list what you think. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

HLR and EAP-SIM integration
by Thus0 Petrus 02 Aug '12

02 Aug '12

Hello everybody, I'm trying to make a testbed for EAP-SIM with freeradius to authenticate on a WLAN network. it works well thanks to the patch provided by seek-for-android : you can see the details here : http://code.google.com/p/seek-for-android/wiki/EapSimAka but you need to store IMSI, RAND, SRES, KC in a flat file as by default, we don't have the Ki of SIM cards and don't have a HLR so we need to precalculate these values. For our testbed, we're using some MagicSIM we've programmed with our own Ki. So I wonder if anybody has already done some integration of freeradius with openbsc HLR to do EAP-SIM ? Or is there a tool to calculate the triplets (RAND, SRES, KC) with input the IMSI (and Ki stored in the database) ? If not, could someone points me where to start to write my own tool ? I don't think pysim can do it... I found an entry about A3/A8 authentication here http://openbsc.osmocom.org/trac/changeset/3606cc576502b95d4973fac2af76d1b9b… int get_authtuple_by_subscr(struct gsm_auth_tuple *atuple, struct gsm_subscriber *subscr) ...but I want to calculate gsm_auth_tuple, not retreive it from the database... Thanks for any information :) -- Thus0

EMFCamp - A UK Hackcamp this summer!
by Paul Dart 01 Aug '12

01 Aug '12

Hello ! Although not entirely on topic, Harold is happy for me to post to these lists about an event I've been involved in. Electromagnetic Field is a UK hacker/maker camp that is occurring in just under a months time. In case you haven't, here's the gist: Electromagnetic Field is a non-profit three day camping festival for people with an inquisitive mind or an interest in making things: hackers, geeks, scientists, engineers, artists, and craftspeople. It's taking place in Milton Keynes between the 31st August and the 2nd September and is inspired by European camps such as the Chaos Communication Camp and Hacking At Random, which means that we have an absurd internet connection to a field, and power to every tent. There will be talks and workshops on everything from genetic modification to lockpicking, blacksmithing to high-energy physics, reverse engineering to electronic engineering, quadcopters to beer brewing and crocheting to carpentry. If you decide to talk about something, there's space for you to do so, and plenty of people who want to listen. The campsite will be littered with interesting things to play with and explore, from ride-on tanks to giant dinosaurs. And more lasers than you can shake a laser-covered stick at. Attendees are encouraged to form villages and put on activities for other people around the camp, and we're going to have villages covering everything from gaming to 3D printing. If you'd like to form a village, get in touch! https://www.emfcamp.org/tickets Your ticket will give you the following things: * A secure place to camp for three days. * Power to your tent. * Very fast internet access (both wired and wireless). * Access to running water and hot showers. * A whole pile of awesome talks and workshops by amazing people. * A full bar. * One fully programmable camp badge, equipped with wireless communications. * A campsite equipped with weird and wonderful things to play with. * A weekend unlike any other in the UK. If we've still not sold you, maybe you should read our website and blog, which have exhaustive information about the camp: https://www.emfcamp.org http://blog.emfcamp.org If you've got any questions feel free to email me or the team!

Hello, Interesting looking A-Bis test equipment on eBay right now: http://www.ebay.co.uk/itm/GN-EGM-Nettest-35-GSM-A-Bis-Test-Meter-Elmi-EGM35… Appears to be PCM only though and I imagine of limited usefulness. Best, Andrew -- Andrew Back http://carrierdetect.com
