Can you record the video about the presentations and upload to some video sharing site ? I'm certain, that there would be some interest watching it :) Thanks, Zsombor On 2012.03.30. 13:33, "Tobias Engel" <t-openbsc(a)tobias.org> wrote: On 29.03.2012 21:41, Peter Stuge wrote: > Harald Welte wrote: >> I was pondering to start a regular ...

DOS in Cellular network
by Chengcheng Gou 30 Mar '12

30 Mar '12

Hello I want to know how to implement a real DOS in the real cellular network using RACH Flood.As you know, using OsmocomBB ,you can only send flood to one ARFCN at one time, so the phone can seaching for another ARFCN. So I think the RACH Flood is less effective in practice, how about it? and if not,a better suggestion on DOS in Cellular network? Thanks!

RSSI Firmware of OpenMoko GTA02
by saad_aol 28 Mar '12

28 Mar '12

Hi; I am trying to run rssi.highram.bin on gta02(openmoko) following this [1] gta02 is running SHR-lite distro So far I have 1. cross-compiled rssi firmware using arm-elf- toolchain 2. cross-compiled osmocon for phone using arm-angstrom-linux-gnueabi- [2] make -e CROSS_TOOL_PREFIX=arm-angstrom-linux-gnueabi- HOST_CONFARGS="--host=armv4t-angstrom-linux-gnueabi" 3. Make sure that nothing else is using /dev/ttySAC0 4. loaded rssi firmware on gta02 by running on gta02 ./osmocon -i 13 -m romload -p /dev/ttySAC0 rssi.highram.bin Firmware loads succesfully when I toggle power of baseband using echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on && echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on but it scans only ARFCN 1 :< SIM is present but since /dev/ttySAC0 is only claimed by osmocon, I dont think it can be used by ogsmd [1] http://bb.osmocom.org/trac/wiki/OpenMoko http://bb.osmocom.org/trac/wiki/OpenMoko [2] http://wiki.openmoko.org/wiki/Toolchain http://wiki.openmoko.org/wiki/Toolchain My QUESTIONS are: ================= 1. How can I Scan all ARFCN? 2. Can we use /dev/ttySAC0 for gsm & other things after the firmware is loaded on baseband?
