ANN: osmo-pcap a PCAP Client and Server application
by Holger Hans Peter Freyther 03 Jun '11

03 Jun '11

Hi, I wrote a very primitive client and server for PCAP. The osmo_pcap_client will use libpcap to sniff on a local link, we have the usual VTY interface to configure it, one can change the filter and the device at runtime. There is also a very simple server that authenticates clients based on the remote address, that will write the pcap files to disk. The files will be rotated based on time and size, but also when the Link Header of a client is changing. The traffic is not encrypted yet but that is on the todolist. The code can be found in our git repository[1]. holger [1] http://cgit.osmocom.org/cgit/osmo-pcap/

[PATCH 00/10] Control interface for OpenBSC
by Daniel Willmann 03 Jun '11

03 Jun '11

Hello, this patchset adds an SNMP-like control interface to OpenBSC. Currently you can set and get variables. This interface is enabled in osmo-bsc, osmo-bsc_nat, and in osmo-nitb. It currently supports querying the counters and rate counters, setting and querying the rf_locked status, and geographical location. In osmo-bsc_nat forwarding is implemented to set/query stuff in the actual osmo-bsc. The patches are located in the daniel/controlif branch. Please merge them if you feel they are ready or point me to the problems. Regards Daniel Willmann (10): Add documentation for the control interface protocol Add example to communicate through the control interface Add libctrl, an SNMP-like control interface libctrl: Add macros to help define commands libctrl: Add commands to query counters and rate_cntr bsc_hack: Use libctrl, listen on port 4249 osmo_bsc: Use libctrl, handle ctrl cmds on port 4249 or from the nat osmo_bsc: Add some libctrl commands libctrl: Add ctrl_cmd_cpy() to copy a command nat: Use libctrl and add command forwarding to osmo-bsc openbsc/configure.in | 1 + openbsc/contrib/bsc_control.py | 100 +++++ openbsc/doc/control-interface.txt | 21 + openbsc/include/openbsc/bsc_nat.h | 22 + openbsc/include/openbsc/control_cmd.h | 151 +++++++ openbsc/src/Makefile.am | 2 +- openbsc/src/libctrl/Makefile.am | 7 + openbsc/src/libctrl/control_cmd.c | 479 +++++++++++++++++++++++ openbsc/src/libctrl/control_if.c | 627 ++++++++++++++++++++++++++++++ openbsc/src/osmo-bsc/Makefile.am | 1 + openbsc/src/osmo-bsc/osmo_bsc_main.c | 167 ++++++++ openbsc/src/osmo-bsc/osmo_bsc_msc.c | 34 ++ openbsc/src/osmo-bsc_nat/Makefile.am | 1 + openbsc/src/osmo-bsc_nat/bsc_nat.c | 279 +++++++++++++ openbsc/src/osmo-bsc_nat/bsc_nat_utils.c | 1 + openbsc/src/osmo-nitb/Makefile.am | 3 +- openbsc/src/osmo-nitb/bsc_hack.c | 3 + 17 files changed, 1897 insertions(+), 2 deletions(-) create mode 100755 openbsc/contrib/bsc_control.py create mode 100644 openbsc/doc/control-interface.txt create mode 100644 openbsc/include/openbsc/control_cmd.h create mode 100644 openbsc/src/libctrl/Makefile.am create mode 100644 openbsc/src/libctrl/control_cmd.c create mode 100644 openbsc/src/libctrl/control_if.c -- 1.7.5.rc3

Only nanoBTS, or any femtocell?
by Bthomas 30 May '11

30 May '11

Dear OpenBSC lovers and developers! question, I turn towards you again: if the operation OpenBSC nanoBTS and A-bis Over IP basis, you think any of the femtocell (eg Vodafone's preferred cells) are able to operate in the same way? I think that the same standard as well do they work? What is your opinion? For more information: http://wirelessfederation.com/news/74803-vodafone-hungary-launches-3ghsdpa-… Thank You, and have nice day! bthomyka from Hungary

How does the phone know if it is roaming or not? When my phone camps to OpenBTS network it says it is roaming but in OpenBSC it doesn't. I wonder what makes such difference Sent from my iPhone

two questions
by Hans Witvliet 27 May '11

27 May '11

Hi all, Got two questions: Firstly, i would like to know if it is possible to have bts and bsc at completely different locations: can the connections be encapsulated in a vpn tunnel (openvpn, ipsec). Or is that connection very sensitive to latency? Secondly, anybody ever looked at the new nanobts/femtobts from "radio access"? Probably they don't manufacture those themselves, but are re-selling it allong with their own bsc/nomc/hlr (clarity) Clarity should be able to handle the new nanobts aswell as the model from ipaccess. >From what i read, it is scalled down model compared to the nano-bts from ipaccess. And scaleddown in two aspects: Limited power: just 200mW and price: around 50 euro. hw
