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

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.
Jason

Hi Andreas, Harald,
the recent "SI generation" fix broke multi trx setups. This is because
when the first (c0) TRX is going up bts->si_valid will include SI2 and
other SIs scheduled on the BCCH and once the second trx is going up the
code decides it only needs to generate the SI5 (and more).
But si_valid still includes SI2 and it will be set on the second trx. I
have fixed it locally by setting si_valid to 0 early in the set_system_infos
routine and added a warning for this case.
How should this be properly fixed for master? Will the content of a specific
SI differ from TRX0 to TRX1 of a BTS? Should the si_valid be moved to the
trx data structure?
I have attached my local patch and would like to have a review for it.
comments? ideas?
