hi holger, it worked. thanx for your help. but now i got stuck here: ./configure in openbsc: checking for LIBOSMOCORE... configure: error: Package requirements (libosmocore >= 0.1.6) were not met: No package 'libosmocore' found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables LIBOSMOCORE_CFLAGS and LIBOSMOCORE_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. "pkg-config --list-all" does not show libosmocore. my directory: "dir /usr/local/lib/pkgconfig/" shows libosmocore.pc and spandsp.pc, nothing else. it seems that my version of pkg-config stores it somewhere else. my version is 0.23. with that it works, but it should be easier, i think: LIBOSMOCORE_LIBS=/usr/local/lib/ LIBOSMOCORE_CFLAGS=-I../libosmocore/include/ LIBOSMOVTY_LIBS=/usr/local/lib/ LIBOSMOVTY_CFLAGS=-I../libosmocore/include/ ./configure now i get these errors when compiling openbsc: gsm_04_11.c:343:16: error: invalid suffix "b111" on integer constant ... the source sais "switch (fi & 0b111) {". i never saw binary values in C.

New OpenGGSN project mailing list / 0.90 release
by Harald Welte 25 May '10

25 May '10

Hi! This is just a notification that I've now created a mailing list related to OpenGGSN development. As the entire OpenGGSN project is running on sf.net, the mailinglist is also running there: https://lists.sourceforge.net/lists/listinfo/ggsn-devel So if you're interested in following what's happening in OpenGGSN, I suggest you subscribe there, too. I understand it would probably make more sense to simply move the entire project to osmocom.org and use this very openbsc list (it is low-traffic, after all) - but we never know if the original author wants to come back, and I'd be able to keep that door open for him and thus the project separate and on sf.net. I've also made a openggsn-0.90 release including various bugfixes that were contributed trough the last 5 years, as well as one criticial security fix. You can obtain it from: http://sourceforge.net/projects/ggsn/ Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Hi, I have git clone the openbsc program and encountered problem running osmo_sgsn, got the following error messages: " There is no such command. Error occurred during reading below line: nsip local port 23000 Failed to parse the config file: 'osmo-sgsn.cfg' <0014> sgsn_main.c : 170 Cannot parse config file. " Appreciate help on this.

[sourceforge] #11031: Abandoned Project Takeover: OpenGGSN (ggsn)]
by Harald Welte 22 May '10

22 May '10

Hi all, as you can see from the attachment, the OpenGGSN takeover request at soruceforge has been resolved earlier than expected, since the original project creator/administrator was not reachable for sf.net. I'll keep you posetd about the further progress.

Project / Program naming
by Harald Welte 19 May '10

19 May '10

Hi all! I think it's about time that we seriously think about how to handle naming of the individual programs as well as the project itself. OpenBSC was always a mis-nomer since what we started with is much more than a BSC: It's an entire GSM network (excluding BTS) in one process. This was mostly due to the fact that OpenGSM was way too generic and I wasn't able to come up with a good name. Meanwhile, we've started project Osmocom (Open Soruce mobile Communications), where work is being done on the MS (phone) side of GSM. The idea was to have a name generic enough for sub-projects. There are currently two such projects: * OsmocomBB - the BaseBand firmware * libosmocore - the shared library with utilities that are used accross programs In OpenBSC, we currently have the following executables: * bsc_hack - the gsm network-in-a-box * bsc_msc_ip - the actual BSC-only version talking to a real MSC * bsc_nat - the A interface NAT * bsc_mgcp - the media control gateway * osmo-gbproxy - the Gb interface proxy * osmo-sgsn - the soon-to-be-working SGSN as well as a number of utilities like bs11-config, ipaccess-find, ipaccess-config, etc. What Zecke and me have decided some time ago is to move everything under the umbrella of the Osmocom project name. This menans that the homepage and git repositories will move to openbsc.osmocom.org/bsc.osmocom.org and git.osmocom.org (while keeping aliases/redirects in place). What worries me most is the naming of bsc_hack and bsc_msc_ip. I think bsc_msc_ip should be called osmo-bsc, as it is a true BSC implementation. For bsc_hack it's much harder. A logical name would be osmo-gnib (gsm network in a box), but as I've already received tons of complaints about osmocom, I'm not going to come up with even stranger acronyms. However, I want to rename it. It should be prefixed with "osmo-" and the name should not erroneously indicate that we're talking abuot something thats _only_ a BSC. Does anyone on this list have an idea for a good name? For all the other programs, I'd also advocate prefixing them with "osmo-", but that's less of a pressing concern right now.

GPRS / SGSN status update / HOWTO
by Harald Welte 18 May '10

18 May '10

Hi all! Thanks to the support from On-waves, I've been able to focus on my GPRS work during recent weeks. Today, I have managed to actually perform successful PDP context activation / deactivation using a nanoBTS, OpenBSC, OsmoSGSN and OpenGGSN. This is a big step forward, as it means that the GTP interface between our SGSN and OpenGGSN is up and running. The IP addresses allocated are from a pool defined on the GGSN side, and OpenGGSN opens a tun-device for it. Also, the GGSN implementation is much less proof-of-concept now, as it actually maintains propper MM context, PDP context and other state information. However, for reasons that I couldn't figure out (despite many hours of debugging): There are no user/data plane packets anymore. This was already working before I began the GTP / OpenGGSN intergration work 1-2 weeks ago. The PDP context is established successfully on the LLC-GMM SAPI, the phone shows that GPRS is up, but then it doesn't actually even send a single packet (SNDCP, XID exchange, ...) over any of the user data SAPIs. The SAPI and NSAPI have been assigned properly, and I could not find any differece looking at packet traces for both the cases. If you look at the NS-IP / Gb interface of the nanoBTS, not a single gprs protocol message arrives after the PDP context is activated. After a minute or two, the phone then simply disconnects with "Regular Disconnect" cause, as if nothing had happened. Putting the phone in front of an audio amplifier also doesn't reveal any noticable bursts being generated by the phone. For now I'm feeling a bit lost and will work on some other stuff before returning with renewed energy to the SGSN at some later point. In case you want to try it, the following steps are needed: 1) check out OpenGGSN from git://openbsc.gnumonks.org/openggsn.git (master branch), run the usual autoreconf -1 && ./configure && make install 2) check out current OpenBSC master branch and build it. Only if libgtp (installed by OpenGGSN) is found, it will build src/gprs/osmo-sgsn 3) the IP address where 4) Run OpenBSC like usual, however make sure that the followign settings are configured in the openbsc.cfg config file: gprs mode gprs gprs routing area 0 gprs cell bvci 2 gprs nsei 101 gprs nsvc 0 nsvci 101 gprs nsvc 0 local udp port 23000 gprs nsvc 0 remote udp port 23000 gprs nsvc 0 remote ip 123.192.152.236 Where the last ip address is the address of the machine where you will run OsmoSGSN. 5) Configure /etc/ggsn.cfg of your GGSN machine. Check /etc/ggsn.conf (example attached) Run $ sudo ./ggsn -l 192.168.100.239 -d where that address is the local _listening_ address of the GGSN 6) Then simply fire up osmo-sgsn. The only relevant config setting in osmo_sgsn.cfg is: sgsn nsip local port 23000 7) start your favorite mobile phone and register it to your network You can telnet to osmo-sgsn on port 4245, and type the followign commands for some interesting information: logging enable logging filter all 1 logging level ns info logging level bssgp debug logging level llc debug logging level gprs debug logging level mm debug show ns show bssgp show llc show mm-context all show pdp-context all Oh, and last, but not least: Wireshark can debug the Gb interface packets between BTS and SGSN, you simply have to select 'Decode as .... NSIP' on port 23000 packets. It also decodes the GTP between SGSN and GGSN without any extra setting. Have fun! -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
