[PATCH] openbsc/src/ipaccess/ipaccess-find.c: FreeBSD uses IP_SENDIF as analog of the Linux socket option SO_BINDTODEVICE
by Nikola Kolev 07 May '14

07 May '14

IP_SENDIF is broadly an analogue of the Linux socket option SO_BINDTODEVICE. It is used to bypass the traditional BSD source interface selection logic. It is a sledgehammer hack used to output datagrams on a specific interface which may not yet have an address, e.g. for DHCP. -- Nikola

PDP deactivation on a particular cell phone
by ottawa ottawa 02 May '14

Hi Gurus I am using OpenBSC/GPRS with nanoBTS. Thanks everybody for the great work. GPRS works well with many cell phone, but for particular cell phone its not working. I saw Olaf Schulz posting (subject: GPRS problems with Nokia Handsets dated 4th May 2012). Saw his pcap file and mine is similar too. Frank Mass suggested a patch to overcome this problem in his posting (subject gprs_llc.c foreighn TLLI is stored but not searched, dated 30 April 2012). I have implemented that patch but still not working. Can any body suggest something.

[PATCH] contrib/rtp: Use payload data files directly by gen_rtp_header
by Jacob Erlbeck 29 Apr '14

29 Apr '14

This adds a --frame-size option to read payload binary files with a fixed frame size directly. The file must not contain RTP headers. In addition '--rate' and '--duration' can be used to configure the timing.

Network from Scratch on Gentoo: Official Support
by Jason A. Donenfeld 29 Apr '14

29 Apr '14

Gentoo Linux now supports Network from Scratch in 5 easy steps. We're using jolly's branches for the live ebuilds. (ETA on when we can ship master?) Network from Scratch on Gentoo ============================== 1. Add these to packages.keywords (in /etc/portage): =net-wireless/openbsc-9999 ** =net-wireless/osmobts-9999 ** =net-wireless/osmotrx-9999 ** =net-libs/libosmo-abis-9999 ** 2. Make sure your portage tree is up to date, and emerge the right packages: $ sudo emerge --sync $ sudo emerge openbsc osmobts osmotrx 3. Download configuration templates: $ mkdir ~/.osmocom $ wget -O ~/.osmocom/open-bsc.cfg http://bpaste.net/raw/236987/ $ wget -O ~/.osmocom/osmo-bts.cfg http://bpaste.net/raw/237000/ 4. Edit configuration templates to work on spectrum you have a license for: $ vim ~/.osmocom/*.cfg 5. Start these babies up, in separate shells: shell1 $ osmo-nitb -c ~/.osmocom/open-bsc.cfg -l ~/.osmocom/hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM shell2 $ osmobts-trx -c ~/.osmocom/osmo-bts.cfg shell3 $ osmo-trx
