A-bis OML and OM2000 dissectors in wireshark mainline
by Harald Welte 06 Feb '12

06 Feb '12

Hi all, wireshark has merged all pending patches that we were working on. This means that the daily builds from https://www.wireshark.org/download/automated/osx/ and https://www.wireshark.org/download/automated/win32/ will now work out-of-the-box for any pcap traces of OML (Siemens and ip.access BTS) and OM2000 (Ericsson BTS). The ip.access vendor-specific RSL extensions have also been merged. By the way: If anyone was interested in writing a dissector for the Nokia OML dialect, it would be much appreciated. So far, nobody has started, but the OpenBSC code base contains an implementation of the protocol, and the hardware seems to be used by a number of project members, so getting traces should also not be a problem.

Hello All, I've been working on trying to get OpenBSC to work with Asterisk following this as a guide: http://openbsc.osmocom.org/trac/wiki/OpenBSC_LCR http://www.misdn.org/index.php/Howto_for_Debian Basically I'm missing the mISDN_l1loop kernel module. When trying to compile from the mISDN git repository i'm getting the following error when trying to compile (Ubuntu - 10.04 LTS ) ./configure configure: error: kernel build tree does not exist build:/lib/modules/2.6.32-33-generic/build / source:/lib/modules/2.6.32-33-generic/source (Debian - 6.06) passes configure when "make modules" is running make[3]: Entering directory `/usr/src/linux-headers-2.6.32-5-686' CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/l1oip_core.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/l1oip_codec.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/core.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/fsm.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/socket.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/clock.o CC [M] /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.o /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.c: In function âmISDN_freedchannelâ: /root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.c:113: error: implicit declaration of function âflush_work_syncâ make[6]: *** [/root/mISDN/standalone/drivers/isdn/mISDN/hwchannel.o] Error 1 make[5]: *** [_module_/root/mISDN/standalone/drivers/isdn/mISDN] Error 2 make[4]: *** [sub-make] Error 2 make[3]: *** [all] Error 2 make[3]: Leaving directory `/usr/src/linux-headers-2.6.32-5-686' make[2]: *** [modules_] Error 2 make[2]: Leaving directory `/root/mISDN/standalone' make[1]: *** [modules] Error 2 make[1]: Leaving directory `/root/mISDN/standalone' make: *** [modules] Error 2 root@OpenBSC:~/mISDN# I should note that Centos 5.7 and Gentoo give the same errors as Ubuntu....
