Enabling keep-alive for sockets in libosmo-abis

by Holger Hans Peter Freyther

Dear Pablo, Daniel was adding keepalive support to the socket used to talk to the bts. This was done in commit 8c2591d95e17eb6fa868e4d886a63ac62f3ca8af of OpenBSC and somehow needs to find its way to master of OpenBSC or libosmo-abis. I think it belongs into libosmo-abis but I am not sure where exactly. Is the keepalive setting something that belongs into the e1inp_line and configuration? Do you have an idea where I should add it? thanks holger

Problem integrating OpenBSC (osmo-nitb) with LCR

by David Perez

Hi! First of all, let me thank you all the developers and contributors of both OpenBSC and LCR. Congratulations for your amazing work! I am stuck with a problem while trying to get LCR and openbsc to work together through their unix socket (/tmp/bsc_mncc), and I was wondering if anyone on this list would be kind enough to give me some pointers. I include more details below, but this is the executive summary: I have two MS that can call each other with no problem when I start openbsc (osmo-nitb) in standalone mode (i.e. without the "--mncc-sock" option). However, when I start omso-nitb with that option, and I also start LCR, a call between the two MS cannot be establised. I think the problem may be related with the fact that LCR is not being able to identify the calling number, nor the called number, nor the IMSI of the caller. This can be seen in the following trace/debug messages of LCR: --- 000000 TRACE 13.09.12 18:17:49.248 CH(1): MNCC_SETUP_IND LCR<->BSC calling imsi= dialing number= [...] 000000 DEBUG (in apppbx.cpp/ea_message_port() line 2476): EPOINT(1) incoming call from callerid=imsi-, dialing= --- AFAIK, I'm using the latest version of each tool: I am using clones of the following git repositories, made around 10:00 AM CET today (13sep12): --- git clone git://git.osmocom.org/libosmocore.git git clone git://git.osmocom.org/libosmo-abis.git git clone git://git.osmocom.org/openbsc.git git clone git://git.misdn.eu/lcr.git/ --- At the end of this message I include a list of the last commits of these repositories, for reference. --- Executive summary ends here --- The long version of the explanation of the problem follows. I hope to have included enough information, but if you need extra details, please do not hesitate to let me know. First, without LCR, I start openbsc (osmo-nitb) in standalone mode, make a call from 2203 to 2201 (extension numbers I assigned in hlr.sqlite3), and everything works fine (the call gets established and voice flows in both directions): --- root@tli-pc-2001:/usr/local/bin# cat start-bsc-standalone #!/bin/sh echo "" echo "Starting _new_ BSC (openbsc) (=osmo-nitb) standalone..." /opt/new/openbsc/bin/osmo-nitb -c /etc/opt/new/openbsc/openbsc.cfg \ -l /var/opt/new/openbsc/hlr.sqlite3 root@tli-pc-2001:/usr/local/bin# start-bsc-standalone Starting _new_ BSC (openbsc) (=osmo-nitb) standalone... <0019> input/ipaccess.c:923 enabling ipaccess BSC mode DB: Database initialized.
