So far three persons have indicated their interest to join
a meeting at my place.
Considering the time it takes to drive to my place, it
probably makes sense to have the meeting at the weekend
(either Saturday or Sunday) so that there is more time
for the meeting itself. I can suggest one of the following
dates for the first meeting, somewhere between 10:00 to
18:00 on each day:
25.8. (Sa) or 26.8. (Su)
1.9. (Sa) or 2.9. (Su)
8.9. (Sa) or 9.9. (Su)
So please let me know when you have time and also make
suggestions in which Osmocom topic you are interested
in so that we can have some sort of agenda for the
meeting to make best use of the time.
Best regards,
Dieter

Hello everyone,
I've just finnished writing together a small web interface for the OpenBSC
HLR. It allows you to modify various parameters in the database and also
provides a set of functions to modify the HLR or sending SMSes in your own
scripts.
The project is still very alpha but it seems to work reasonably good. Feel
free to give any feedback!
Screenshots and source code is available on my website:

Hello list,
First of all congratulation to developers of this project making such
wonderful project in an interesting subject. I am new to this project and
for past few days i managed to go through the documentation and get most of
it tested. Thanks for pretty good documentation in most of the areas as
well.
I have the osmo-nitb working very fine using a nano bts.
How ever when i try to install it with LCR to interconnect with external
switch, im facing some problems. Initially i thought i must use
LCR+Asterisk. But later i figured out there is a built in SIP interface on
LCR which there is no need to asterisk or chan_asterisk. I would prefer to
use this LCR SIP interface as i dont want to use asterisk and just want to
forward all calls to another SIP switch.
Now in this context there seems absolutely no documentation on both openbsc
and LCR/mISDN lists.
Can some one please shed me some light here on how to build a LCR with SIP
to be work with osmo-nitb.
All i want to test is
GSM phone > Osmo-nitb > LCR with SIP > SIP softswitch
Thank you very much for every one's effort in this project and would be
glad to see some response for this.
Best Regards
Nava.
Dear Pablo,
getaddrinfo does not work for the combination of AF_INET, SOCK_RAW
and IPPROTO_GRE. I have attached an example application that can be
compiled with:
$ gcc -o fr fr.c `pkg-config --cflags --libs libosmocore libosmogb`
this prints:
getaddrinfo returned NULL: Success
FAILED
gettadrinfo returns -8 which should be this:
# define EAI_SERVICE -8 /* SERVICE not supported for `ai_socktype'. */
I am not sure what is the most clever way to resolve this. Make SOCK_RAW
branch out early and do the socket/bind(/listen) manually, use getaddrinfo
twice with some more unspefici options, just deal with SOCK_RAW differently
now? The attached code has the benefit of at least handling INET and INET6
inside the getaddrinfo result.
any ideas?

Hi guys,
i'm still testing the eap-sim authentication and lately i got acceptable results using
a simple flat file containing the triplets of specific SIM cards. Next step will be to
enable the external radius server to use the sysmoBTS database hlr.sqlite3, so the
OpenBSC users (Users using the OpenBSC-GSM Network) can automatically access
to the internet.
i just want to ask if there are any limitations with the sysmocom SIM cards?
In fact, i noticed that by using the sysmocom sim cards, the eap-sim authentication
failed when the RAND values strong randomly chosen were, e.g
046DBA898016454aB3920C58180DA2F5 or e177842fe16c47de84784be1b4141c27.
But when i chose a RAND like this 10101010101010101010101010101010,
0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F0F or 00000000000000000000000000000000,
the authentication succeeded.
By using an other sim (not from sysmocom) with the same strong and weak RAND
values the authentication always succeeded.
Why does the authentication succeed buy using sysmocom sim card with weak RAND
(10101010101010101010101010101010) and fail by using strong RAND values
(e177842fe16c47de84784be1b4141c27) ?
best regards

Hi all,
as the year 2012 has already ended or will soon end depending on your
timezone, it might be a good occasion to start thinking of an OsmoDevCon
2013.
I personally percevied OsmoDevCon 2012 as a big success, and it was fun
to bring everyone together.
Generally, I prefer to keep the spirit of an invitation-only
developer+contributor-only event of those involved in Osmocom. At the
same time, I would consider it a good idea to add a one day
user-conference to the schedule, where we try to get interested users up
to speed with the various projects, possibly including some workshops
and the like.
So schedule-wise, I would suggest something like:
* one day user conference
* two day developer/contributor event
* optionally: 1-2 "hacking days".
The concept of "hacking days" has proven to be quite useful for the
netfilter project in the past (Pablo and I can acknowledge to that
fact). I'm not sure how many people would be able to spend even more
days of their schedule, but even if it's a much smaller group it would
still be useful, IMHO.
I'd like you to
1) provide feedback on the ideas about the one-day user event and the
hacking days
2) consider whether late march (like 2012) would be a good schedule
again
3) what we can improve from the last event
In terms of improvements, I so far have noted down:
* larger venue needs to be found
* complaints about the venue not having sufficient heating
Venue-wise, I would again suggest to hold it in Berlin, as it's
reasonbly well connected, has lots of low-cost flights to it,
accomodation is not too expensive and holger/me/sysmocom can take care
of local organization related activities. Hoewver, if somebody has a
strong opinion against berlin _and_ is willing to organize it, I'm not
completely against another venue.
Regards and happy new year,
Harald

Hi,
I have rebased, extended and fixed the channel assignment and
release. It brings us closer to the GSM 04.08 specification but
there are still sime minor violations for the abnormal handling.
I have tested (using the FakeBTS) a phone not acting on the
SACCH deactivate/RF Channel Release and the signalling link
will be released (T3109).
I have a manual SMS submit test and I can make the nanoBTS crash
easily. I have rebased through each individual change and couldn't
reproduce the crash. I think it is either something in the RF
setup (the modem bank being too close to the BTS), the older modem
firmware, etc.
Anyway, please review and test the branch. I plan to merge it by
Wednesday.
thanks

Hi,
I pulled a newer openbsc version today for the first time in several months.
Now, when a phone sends an IMSI Detach, osmo-nitb segfaults.
The reason seems to be:
osmo_msc.c:msc_compl_l3 gets called from gsm0408_rcvmsg, which in turn
calls gsm0408_dispatch which at some point ends up in
gsm48_rx_mm_imsi_detach_ind, which calls msc_release_connection, which
calls gsm0808_clear, which sets conn->bts = NULL.
Now, back in msc_compl_l3, trans_has_conn is called, which tries to
dereference conn->bts->network, which causes the segfault.
It might have been introduced with Holger's patch "msc: Attempt to
release the lchan immediately on IMSI Detach" (153b13b0), but that was
already in July...

I was Googling open source GANC and came across you web page:
http://openbsc.osmocom.org/trac/wiki/osmo-ganc
I am interested in learning how to program handsets to work with a GANC
controller. Because I am new at this, I am not sure if it is possible to
add this functionality to an existing platform and would like to learn more
about existing implementations.
Is there a good resource (code examples) to look view?
Thank you.

This a series of 3 patches for libosmo-crypt-a53, branch master.
Former HEAD was 3de78cd69c0594b0903e6cfffab7920c69e2d478.
The patches clean up the autotools configuration.
The library itself is not changed[1].
Fell free to merge the patches if they seem useful.
Kind regards,

hi pierre,
the chan_lcr to asterisk is now an interface. you can define multiple
interfaces, if you like to use different contexts. (in this case it is
"from-lcr".)
exten => _.,1,Dial(LCR/ast/${EXTEN:0})
in order to define what interface to be used, name it in the dial app at
extensions.conf. ("ast" in this case.)

Can someone share their configuration files used to run openbsc with new
LCR?
The newest LCR branch jolly/new does not seem to be understanding old
configurations on openbsc wiki.
Remote application=asterisk context=xyz does not work.
Please help me with configuring LCR
Thank you,
I have some questions:
1) When I start bsc_hack bsc_init.c first establishes OML link and
initializes the bts then it establishes RSL link and bts starts
broadcasting. However, it takes so much time to start the bts. Instead of
this I want to do the following: it establishes OML link at the beginning
and only once, then when i want to start broadcasting it establishes just
the RSL link and bts will start faster since i don't have to wait for OML
link. What should be done for this?
2) If i send one or two word messages from telnet interface it is okay. But
if i send a longer message the phone could't receive the end of the message
correctly(last words may be incomplete). Did any one encounter with this
problem? What is wrong with me?
3) Could I send SMS in which extension of the sender is text not integer.
For example, i want to send an information SMS that this is a test network.
For this purpose i want to send an SMS from 'OpenBSC'. I set the extension
of the first subscriber in database as text and tried to send the SMS but
SMS wasn't delivered. What should i do?
4) Can i add SMS externally to SMS table of database?
Thanks.

Hi,
I have a problem with running 2 software programs OpenBSC (osmo-nitb
and osmo-sgsn).
When I run osmo-nitb:
ROOT: /media/obsc_gprs/gitrep/openbsc/openbsc/src/osmo-nitb# ./osmo-nitb
There is no such command.
Error occurred during reading below line:
logging level mi notice

______________________________________________________________
However, when I run osmo-sgsn:

Anybody help?
