UMTS-Stick on nano3G?
by Andreas Mueller 19 Apr '17

19 Apr '17

Hello, I tried to use a Huawei E1823 UMTS-Stick on a debian8-laptop with wvdial and pppd to connect to a nano3G for getting an IP/Internet-connection via UMTS/HSDPA. The setup is mainly as described on http://osmocom.org/projects/cellular-infrastructure/wiki/Getting_Started_wi…. When using an android-Smartphone with the same configuration of the ggsn and the other components the IP/Internet-connection is working. After pppd is started from wvdial it receives his local IP-address from the "net 192.168.99.0/24" parameter of ggsn.conf and also the configured DNS-Server, but no remote-IP, so 10.64.64.64 is used by pppd as a default value: ... --> local IP address 192.168.99.5 --> pppd: ï¿½[7f] --> remote IP address 10.64.64.64 --> pppd: ï¿½[7f] --> primary DNS address 8.8.8.8 --> pppd: ï¿½[7f] ..which results in an unusable ppp0-device: ppp0 Link encap:Point-to-Point Protocol inet addr:192.168.99.5 P-t-P:10.64.64.64 Mask:255.255.255.255 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 Has anybody successfully used an UMTS-Stick with ggsn? How can I tell ggsn to send his IP-Adress, which can be used by pppd as "remote IP address"? Are there special options for pppd which I have to use? thanks and greetings, Andreas

Control Interface related testing
by Harald Welte 16 Apr '17

16 Apr '17

Dear all, I have just submitted some patches which allow test cases to use the Control Interface internally, without binding to a TCP port. See https://gerrit.osmocom.org/#/c/2375/ and https://gerrit.osmocom.org/#/c/2376/ Using this, one can now write unit tests for control commands, without having to go for a multi-process setup with an external control client connected to the control TCP port (which is not easily possible in CI as the port might be used by another test case, ...) -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Hi, We just finished installing the following osmo elements using Ubuntu 14.04 and the procedures from this link: https://osmocom.org/projects/cellular-infrastructure/wiki/Ettus_USRP_B2xx_f… https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_source * libosmocore * libosmo-abis * libosmo-netif * openggsn * libosmo-sccp * openbsc * osmo-pcu * osmo-trx * osmo-bts We are now trying to run each applications to test osmo.

weekly test report (w14 2017)
by Joachim Steiger 07 Apr '17

Hi, this is the BTS test report for week14 2017. BTS models which have been tested with OsmoNITB are: - sysmoBTS1002 - octasic OCTBTS3500 - ettus USRP B200 - nanoBTS model:165G Most test cases have passed: sysmobts and nanobts worked without issue. the only one failing were with the octbts: the issues there were reliability of establishing a voicecall and or gprs. only every 2nd or 3rd attempt works. on the 3 TCH/H, 3 PDCH config gprs was not working at all with the ettus B200 everything worked but gprs seemed extremely slow or lossy. i could only view small testpages, big graphics do not load.

[RFC] Coding Style: Longer Line Lengths?
by Harald Welte 06 Apr '17

06 Apr '17

Dear all, [Despite today being April 1st, this is not an april fool's joke] ever since the start of the Osmocom project, we have adopted pretty much 1:1 the Linux Kernel coding style. Having a uniform coding style all over the project is important for readability, and from my point of view it doesn't really matter too much which style it is, as long as it is uniform accross the projects. I'm still fine with the Linux kernel coding style for most parts, but I think we could consider allowing longer lines. 80 characters is still nice here and there, but maybe something like 100, 120 or even 130 might actually make the code more readable and permit us to use slightly longer identifiers without having to wrap every second statement in the code. What do people generally think here?

DBus usage
by Neels Hofmeyr 05 Apr '17

05 Apr '17

Hi Pau (and maybe others), here is a test script that showcases how I'd like to use DBus in the osmo-gsm-tester: use pydbus and keep the glib main loop in a thread (to handle DBus signals only). It sounds ambitious but the test program actually works. Would be great to hear your opinion on it: http://git.osmocom.org/osmo-gsm-tester/tree/selftest/dbus_test/ofono_client… The same thing cosmetically rearranged as module stub: http://git.osmocom.org/osmo-gsm-tester/tree/src/osmo_gsm_tester/dbus_client… Thanks! ~N Related: OS#1980 https://osmocom.org/issues/1980 -- - Neels Hofmeyr <nhofmeyr(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschäftsführer / Managing Directors: Harald Welte

osmo-bts Installation Issue
by Ron 04 Apr '17

04 Apr '17

Hi All, Requesting your help regarding the case that we had encountered during the installation of osmo-bts using UBUNTU 14.04 as OS. Without using the 201509-fairwaves-rebase, the installation go past through. Unfortunately, there is no “osmo-bts-trx” executable. Below are the steps we followed for the installation of osmo-bts. cd /opt/osmo/src/ git clone git://git.osmocom.org/osmo-bts cd osmo-bts autoreconf -fi ./configure make -j5 make check make install We tried using the 201509-fairwaves-rebase, but unfortunately the installation stops and an error was encountered during the “make” process. Below are the installation steps and error encountered: cd /opt/osmo/src/ git clone git://git.osmocom.org/osmo-bts cd osmo-bts git checkout 201509-fairwaves-rebase autoreconf -fi ./configure --enable-trx make Error encountered: make[2]: Entering directory `/opt/osmo/src/osmo-bts/src' Making all in common make[3]: Entering directory `/opt/osmo/src/osmo-bts/src/common' CC gsm_data_shared.o CC sysinfo.o CC logging.o CC abis.o abis.c: In function ‘abis_open’: abis.c:233:25: warning: assignment discards ‘const’ qualifier from pointer target type [enabled by default] bts_dev_info.unit_name = model_name; ^ abis.c:236:25: warning: assignment discards ‘const’ qualifier from pointer target type [enabled by default] bts_dev_info.location2 = model_name; ^ CC oml.o oml.c:46:30: error: conflicting type qualifiers for ‘abis_nm_att_tlvdef_ipa’ static struct tlv_definition abis_nm_att_tlvdef_ipa = { ^ In file included from oml.c:33:0: /usr/local/include/osmocom/gsm/abis_nm.h:37:36: note: previous declaration of ‘abis_nm_att_tlvdef_ipa’ was here extern const struct tlv_definition abis_nm_att_tlvdef_ipa; ^ oml.c:373:6: error: nested redefinition of ‘enum abis_nm_t200_idx’ enum abis_nm_t200_idx { ^ oml.c:373:6: error: redeclaration of ‘enum abis_nm_t200_idx’ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:647:6: note: originally defined here enum abis_nm_t200_idx { ^ oml.c:374:2: error: redeclaration of enumerator ‘T200_SDCCH’ T200_SDCCH = 0, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:648:2: note: previous definition of ‘T200_SDCCH’ was here T200_SDCCH = 0, ^ oml.c:375:2: error: redeclaration of enumerator ‘T200_FACCH_F’ T200_FACCH_F = 1, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:649:2: note: previous definition of ‘T200_FACCH_F’ was here T200_FACCH_F = 1, ^ oml.c:376:2: error: redeclaration of enumerator ‘T200_FACCH_H’ T200_FACCH_H = 2, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:650:2: note: previous definition of ‘T200_FACCH_H’ was here T200_FACCH_H = 2, ^ oml.c:377:2: error: redeclaration of enumerator ‘T200_SACCH_TCH_SAPI0’ T200_SACCH_TCH_SAPI0 = 3, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:651:2: note: previous definition of ‘T200_SACCH_TCH_SAPI0’ was here T200_SACCH_TCH_SAPI0 = 3, ^ oml.c:378:2: error: redeclaration of enumerator ‘T200_SACCH_SDCCH’ T200_SACCH_SDCCH = 4, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:652:2: note: previous definition of ‘T200_SACCH_SDCCH’ was here T200_SACCH_SDCCH = 4, ^ oml.c:379:2: error: redeclaration of enumerator ‘T200_SDCCH_SAPI3’ T200_SDCCH_SAPI3 = 5, ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:653:2: note: previous definition of ‘T200_SDCCH_SAPI3’ was here T200_SDCCH_SAPI3 = 5, ^ oml.c:380:2: error: redeclaration of enumerator ‘T200_SACCH_TCH_SAPI3’ T200_SACCH_TCH_SAPI3 = 6 ^ In file included from oml.c:32:0: /usr/local/include/osmocom/gsm/protocol/gsm_12_21.h:654:2: note: previous definition of ‘T200_SACCH_TCH_SAPI3’ was here T200_SACCH_TCH_SAPI3 = 6 ^ make[3]: *** [oml.o] Error 1 make[3]: Leaving directory `/opt/osmo/src/osmo-bts/src/common' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/opt/osmo/src/osmo-bts/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/opt/osmo/src/osmo-bts' make: *** [all] Error 2 We followed the installation process from the URLs below: https://osmocom.org/projects/cellular-infrastructure/wiki/Ettus_USRP_B2xx_f… https://osmocom.org/projects/cellular-infrastructure/wiki/Build_from_source Best Regards, Ron Rylan B.

RFC: speed up gerrit verifications by using dependency artifacts
by André Boddenberg 31 Mar '17

31 Mar '17

Hi, some weeks a go the topic about using dependency-artifacts to speed up gerrit verifications was mentioned by Neels in the "RFC: jenkins pipeline" thread [1]. I was curious and wrote a bash script (osmo-artifacts.sh) [2], which enables build jobs to archive and fetch dependencies. Instead of Docker it simply uses archives to store them. An artifact's name has the following form: ( n(${project}.${branch}.${shortRev}_) ).tar.gz Openbsc builds are 50 % faster when using artifacts. [3] The jenkins.sh [2] script had to be slightly modified i.e. basically split into two functions: 1) buildProjectDeps() 2) buildProject() A third function to generate the artifact name has been added. The template.sh [2] script illustrates this description. What do you think about the result/artifactStore/approach in general? A cleanUpArtifactStore.sh script running as a cron job is already on my mind, but imo it's a good point to discuss the intermediate result. blobb [1] http://lists.osmocom.org/pipermail/openbsc/2017-March/010400.html [2] git clone https://github.com/blobbsen/diy-artifacts.git [3] https://jenkins.blobb.me/job/openBSC_multi-configuration_withArtifacts_test…
