Hi Just ran across your blog and was interested in emulating some real traffic to Cisco GGSN code running on dynamips. Could you please provide me some references where I can start with so that i can get openBSC or openSGSN up and running? Also wondering if you have or aware of a code that emulated MS instead of having real BTS up , Thank you v.much in advance. Anish

some issues configuring openbsc

by Stephen Siadak

While I think I am pretty close to getting my ip.access nanoBTS to communicate with my laptop running osmo-nitb I seem to be running into a problem. I am running openbsc-0.9.13 and using libosmocore-0.1.30 When I start osmo-nitb I see this error: ./osmo-nitb -T -c ./openbsc.cfg DB: Database initialized. DB: Database prepared.

That is fatal. Was the bts type and frequency properly specified? I am using one of the stock nitb configuration files with no modifications. openbsc.git/openbsc/doc/examples/osmo-nitb/nanobts/openbsc.cfg My setup is a little odd. I did not do the original configuration for the nanoBTS. I was hoping to just get stuff working with the current configuration before I changed anything. The nanoBTS comes up with an IP of 2.2.2.1 and expects a gateway of 2.2.2.2. So I simply configured the ip eth0 on my laptop to 2.2.2.2. Then annoyingly the nanoBTS starts looking for 3.3.3.3. Now I start getting a little hacky to try and move stuff along: ip addr add 3.3.3.3/24 dev eth0 ip route add 3.3.3.3/32 via 2.2.2.2 I am able to use ipaccess-find: ./ipaccess-find eth0 # finally shows # MAC Address='00:02:95:00:51:83' IP Address='2.2.2.1' Unit ID='1801/0/0' # Location 1='' Location 2='BTS_NBT131G' Equipment Version='165b029_58' # Software Version='168a302_v142b13d0' Unit Name='nbts-00-02-95-00-51-83' # Serial Number='00106317' I am also able to use ipaccess-config: ./ipaccess-config -u 1801/0/0 -o 2.2.2.2 -r 2.2.2.1 # Trying to connect to ip.access BTS ... # <0005> abis_nm.c:537 OC=SITE-MANAGER(00) INST=(ff,ff,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) # <0005> abis_nm.c:537 OC=BTS(01) INST=(00,ff,ff) STATE CHG: OP_STATE=Disabled # AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=BASEBAND-TRANSCEIVER(04) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # OML link established using TRX 0 # setting Unit ID to '1801/0/0' # setting primary OML link IP to '2.2.2.2' # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,00) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,01) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,02) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,03) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,04) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,05) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,06) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=CHANNEL(03) INST=(00,00,07) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=RADIO-CARRIER(02) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSE(f0) INST=(00,ff,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-CELL(f1) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSVC(f2) INST=(00,00,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=GPRS-NSVC(f2) INST=(00,01,ff) STATE CHG: # OP_STATE=Disabled AVAIL=Not installed(07) ADM=Locked # <0005> abis_nm.c:537 OC=BASEBAND-TRANSCEIVER(04) INST=(00,00,ff) # IPACCESS(0xf0): SET NVATTR ACK # Set the NV Attributes. # The BTS has acked the restart.

[PATCH 0/3] openbsc: ctrl updates

by pablo＠gnumonks.org

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi, These patchset contains the port of libctrl to use the IPA infrastructure available in libosmo-abis. I've also made one small cleanup to bail out in case that we cannot bind to the telnet port. Another patch follows up to avoid disabling nagle (to avoid problems with TCP segmentation, we still have to support this appropriately), I noticed this while doing the port work. Pablo Neira Ayuso (3): ctrl: use generic IPA socket infrastructure available in libosmo-abis src: check for error returned by controlif_setup() ctrl: do not disable nagle algorithm until we fully support segmentation openbsc/include/openbsc/control_cmd.h | 17 +--- openbsc/include/openbsc/control_if.h | 2 +- openbsc/src/libctrl/control_if.c | 153 +++++++-------------------------- openbsc/src/osmo-bsc/osmo_bsc_main.c | 6 +- openbsc/src/osmo-bsc_nat/bsc_nat.c | 6 +- openbsc/src/osmo-nitb/bsc_hack.c | 5 +- 6 files changed, 50 insertions(+), 139 deletions(-) -- 1.7.2.5

[PATCH 0/7] libosmo-abis: updates for generic IPA infrastructure

by pablo＠gnumonks.org

From: Pablo Neira Ayuso <pablo(a)gnumonks.org> Hi! This patchset contains several updates for the generic IPA infrastructure which provides an abstraction upon the generic socket infrastructure for IPA traffic. After this patchset, it will follow up one patch to use it in openBSC. You can find these changes in the pablo/ipa-updates branch of libosmo-abis. Please, merge them. Pablo Neira Ayuso (7): ipa: remove bogus driver_name parameter from ipa_client_create ipa: rename all reference to ipa_*_peer to ipa_*_conn tests: remove reference to internal headers in ipa_proxy_test ipa: use default write callback in ipa_client_conn_create if not specified ipa: fix segfault in ipa_client_conn_create if no E1 timeslot is specified ipa: better log error messages for ipa_msg_recv() ipa: use DEBUG level instead of NOTICE for debugging log messages include/osmocom/abis/ipa.h | 34 +++++----- src/input/hsl.c | 22 +++--- src/input/ipa.c | 153 ++++++++++++++++++++++---------------------- src/input/ipaccess.c | 26 ++++---- src/ipa_proxy.c | 22 +++--- tests/ipa_proxy_test.c | 4 +- 6 files changed, 128 insertions(+), 133 deletions(-) -- 1.7.2.5

[osmocom-announce] patched wireshark now on git.osmocom.org

by Harald Welte

Hi all, we have accumulated a number of wireshark patches, and by far not all of them have been merged into mainline wireshark so far (volunteers, anyone?) Some people have complained that it is hard to build them, as you first have to find a wireshark version to which they apply, etc. We have now created a wireshark.git repository at git.osmocom.org in which you will be able to find the latest mainline wireshark version ('trunk' branch) as well as our patches in 'master': http://cgit.osmocom.org/cgit/wireshark/ the read-onIy clone url is 'git://git.osmocom.org/wireshark' So the recommended option for everyone needing patched wireshark for one or the other reason (e.g. simtrace) now is to clone that wireshark.git repository and build from there. Like before, we will rebase our patches in irregular intervals, so you may have to do a 'pull -f' instead of 'pull' at that time. Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

autoconf fix for libosmo-abis (master)

by Alexander Huemer

This patch adds a version check for ortp, needed because of an upstream API change. libosmo-abis fails to build with ortp <0.15.0.

OpenBSC behind NAT

by Seungju Kim

Hello, i am trying to set up an openbsc network behind NAT. So far i can run the bts with oml/rsl. But the bts fails to connect to the sgsn. I think it is because of the ports. What ports shall i open in order to get it work? And the encalsulation settings could not be matched because the sgsn is behind the nat. Is there a workaround for this?

SysmoBTS?

by Dakota C

I've noticed in the osmo-bts project a lot of references to this 'sysmobts' product and I'm /really/ curious. Now, I know that not a lot will probably be able to be discussed for a bit of time, but for those involved, what can we know /right now/ about it? Any ideal target price? Availability? What it can handle? What it can do? I've also wondered how the 'experimental' work of using OsmocomBB phones as a BTS was ever going - did that ever work? Cheers, -from the desk of Dakota C Support technology in education - because Stone Age administrators never will.
