about the IMSI Detach in various status
by gcc 13 Aug '12

13 Aug '12

Hi, List. I am studying the IMSI Detach attack now. I have some doubt. 1. if the victim is already off-line, what is the effect of the attack? 2. In my network, I send the IMSI detach Indication, and the base station sends me the Channel Release. but the victims is still online,why? I am confused！ -- View this message in context: http://baseband-devel.722152.n3.nabble.com/about-the-IMSI-Detach-in-various… Sent from the baseband-devel mailing list archive at Nabble.com.

Re: Any interest for Osmocom meetings in Bavaria ?

Hello Alexander, On Wed, 8 Aug 2012 20:44:12 +0400, "Alexander Chemeris" <alexander.chemeris(a)gmail.com> wrote: > > I'd love to join, but it strongly depends on the exact dates of the > meeting. 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.

Working of ccch_scan and capturing the SDCCH.
by Altaf 08 Aug '12

08 Aug '12

Hello Sylvain I am using the burst_ind branch and have some doubts. I am using a test network, and it has no encryption. Usually the n/w has a low load and the channel structure followed during the assignment is SDCCH/4 + SACCH/C4 or CBCH(SDCCH/4). and timeslot 0 . SDCCH is assigned on timeslot 0.. The ccch_scan is able to capture the SMS sent on timeslot 0 and also only one of the subchannel as per the above assignment. Just for testing, When I use two phones and send an SMS from both of them simultaneously both are assigned timeslot 0 and different subchannels. CCCH_scan could capture only one SMS. meaning that it could only get one subchannel. Am I right about ccch_scan or does it have the capability to get a complete timeslot. ? Thank you Altaf -- View this message in context: http://baseband-devel.722152.n3.nabble.com/Working-of-ccch-scan-and-capturi… Sent from the baseband-devel mailing list archive at Nabble.com.

Any interest for Osmocom meetings in Bavaria ?
by Dieter Spaar 08 Aug '12

08 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

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!

cp2102 (betemcu, B75937)

...a never ending story: i have a working ftdi-ttl, but the cp2102-adapters (http://www.ebay.de/itm/USB-2-0-to-UART-TTL-6PIN-Module-Serial-Converter-CP2…) with the same cable dont work under ubuntu or windows. if i rub the top of the 2.55mm with my finger random data appears. but the loader doesnt upload the firmware. i used the txd, rxd and gnd pins and checked the connections with a multimeter. i tested -m c123xor, -m c123 and the default firmware. flashing custom baudrates was no problem. rivers are installed correctly (stady ttyusb0 under ubuntu/ com1 under win). is there any hint? -- View this message in context: http://baseband-devel.722152.n3.nabble.com/cp2102-betemcu-B75937-tp3489336p… Sent from the baseband-devel mailing list archive at Nabble.com.
