RJ45 cable
by Eric Cathelinaud 15 May '09

15 May '09

Hi, I just saw you added to the wiki a "step by step" guide to build the RJ45. I was wondering why you are saying you use green white / green cables for pin1&2. I actually pluged in my twinax orange white / orange cables. Are you using a crossed cable? Best regards Eric Cathelinaud

Hello Nordin, On Thu, 14 May 2009 17:26:22 +0200, "Nordin" <bouchtaoui(a)gmail.com> wrote: > > Than I executed the bsc_hack for the nanoBTS (thus I give the > appropriate parameters as described on the webpage), and I get the > following error: > DB: Database initialized. > DB: Database prepared. > mi_setup could not open socket Address family not supported by protocol Do you really provide the correct parameters to bsc_hack ? The current version of bsc_hack requires the parameter "-t nanobts900" or "-t nanobts1800", depending on the type of the nanoBTS you have. If you don't specify the type, the BS-11 is used. Additionally be sure to specify the ARFCN for a nanoBTS 1800 because otherwise the default GSM900 channel 123 will be used which does not work for DCS1800.

SMS interface

hi, i know that there is an SMS application interface to come. but currently i like to send SMS via vty interface. i don't know much about the interface structure of the vty interface. here is what i actually want: a daemon checks the hlr for unauthorized subscribers. for the first entry found, a subscriber extension is assign. additionally an SMS is sent to the subscriber, to inform about the assigned number, the network, and dial plan. the subscriber will sen be authorized in the hlr. this daemon shall run every minute. regards, andreas p.s. the application interface patch is on its way. maybe this weekend.

Greetings from Estonia

Hi I'm new dude in this community. I'm a finn, live in Estonia. I've a background of military radios and their electronic repair, not that much of civilian stuff, nor GSM systems. Also studied some RF stuff in technical institute, but i guess never was the sharpest tool in the shed in this area, spent more time in unix machine room than in RF lab. My plan to be a tester/hangaround here, do some minor hacking but I think my coding skills and limited time leaves it there. If at some stage packaging in Fedora camp is needed, I am already pkg maintainer and could help there. Anyway, your project is very intresting and wish you success in it.

Problem with installing OpenBSC on Centos 4
by Nordin 14 May '09

14 May '09

Hello friends, I've tried to get openbsc running on CentOS, but because of a missing driver (which interfaces between libdbi and sqlite3) it was not a succes. So I removed CentOS and installed Debian Lenny, as I kinda noticed most of you work with Debian. Anyway I managed to install and configure the openbsc with some exceptions. Because I don't use BS-11, but a nanoBTS instead, so I didn't patched the kernel for the mISDN card. I tried the ipaccess-find first, which worked (after I modified my ip hardcoded in the source). Than I tried to configure the nanoBTS using the ipaccess-config as described in this site http://bs11-abis.gnumonks.org/trac/wiki/nanoBTS, but with our ip addresses ofcrouse. That seems to work, but the program doesn't return, I don't know if that is the case. I assume I get response if the nanoBTS gets connected with the OpenBSC. Than I executed the bsc_hack for the nanoBTS (thus I give the appropriate parameters as described on the webpage), and I get the following error: DB: Database initialized. DB: Database prepared. mi_setup could not open socket Address family not supported by protocol Can someone please tell me where to look at? If it's a simple error, just tell me which source does something with mi_setup, otherwise more info would be fine. Thank you. P.S.: I'm a bit new to Linux, so please be patient with me.

Problem : patching the kernel
by Eric Cathelinaud 14 May '09

Hi, I followed Debian_Getting_Started chapter in the wiki. There wasn't any error but, after rebooting, the kernel crashed: Booting 'Debian GNU/Linux, kernel 2.6.27.4' root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /boot/vmlinuz-2.6.27.4 root=/dev/hda1 ro quiet hfcmulti.dslot=1 [Linux-bzImage, setup=0x3000, size=0x1796901] [0.000000] Unknown boot option 'hfcmulti.dslot=1': ignoring [0.796125] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) I tried first to delete "hfcmulti.dslot=1" at the kernel line but still have the second line. After checking the /boot/grub/menu.lst file, I saw that the line initdr was missing for the kernel 2.6.27.4: title 2.6.27.4 root kernel title 2.6.26.2 root kernel initdr In /boot directory, I have initdr files only for 2.6.26.2 and 2.6.26.1. Sorry I am quite weak concerning the kernel. Can anyone help me? Thanks a lot Eric Cathelinaud

It works
by Andreas.Eversberg 10 May '09

hi, finally the layer 4 interface of openbsc is done. also LCR (linux-call-router) talks to libbsc. this turns both into a complete network. libgsm (compiled to LCR) provides audio transcoding. even asterisk can use it via "chan_lcr" driver. today i got my first call to a friend from mobile via fixed network. (because harald did not answer on the first try, he could not receive the previledge of the first call.) before i begin providing patches and documentation, i will make some stability tests. have a nice weekend.. jolly
