RFC: OsmoDevCon 2017 planning
by Harald Welte 10 Dec '16

10 Dec '16

Dear Osmocom Community, [please respect the Reply-To and post all follow-up discussion to this to openbsc(a)lists.osmocom.org, so we avoid having long threads cross-posted to several mailing lists.] >From 2012 to 2016 we were running a series of small, invitation-only Osmocom Developer Conferences. Access was intentionally restricted to those community members who have demonstrated an existing track record of contribution to any of the projects under the Osmocom umbrella. This format of a small, tightly knit group of about 20 people has been successful over the years, and I have received a lot of positive feedback from past participants. On the other hand, the Osmocom project has grown in scope and diversity, and some of those projects don't have all that much relationship to each other - except being started by people from within the same group. There's the cellular communications (GSM/GPRS/EDGE/UMTS and hopefully at some point LTE) protocols which is attracting a lot of professional users. And then there's pure community projects like rtl-sdr, OsmocomBB, OsmocomGMR and many other efforts. Particularly the cellular infrastructure projects (OsmoBTS, OsmoPCU, OsmoBTS, OsmoNITB, OsmoSGSN, OpenGGSN, OsmoIuh & co) are somehow "standing out" of the othe projects in the context of having a wider user bsae, and in that user base also primarily commercial users. So I'd like to start a discussion on how to possibly change the event format to accomodate the various interests and parties. I definitely don't want to loose the "annual meeting of old friends" atmosphere, while at the same time also opening up to other interested parties. One idea would be to keep OsmoDevCon as-is and have a separate event where non-contributing/developing users / sysadmins / system integrators could also be attending. Another idea would be to split into a 'user day' and 'developer days' format. This is something the netfilter developer workshops have been using for many years, and from my limited insight quite successfully so. The "user day" is more like a traditional tech conference, with a large auditorium and talks oriented towards users / sysadmins / integrators of the software. The "developer days" are the invitation-only part, for known contributing developers only, similar to what we have at OsmoDevCon. Having both events (or both parts of an event) back-to-back has the advantage that a large number of potential speakers for the 'user day' are already present, and they don't have to travel yet another time. One could even structure it further and say we have one user day, one public 'Osmocom cellular developer day' and then the closed 'OsmoDevCon classic', maybe reduced from 4 days to 3 or even 2 days only? What is the general opinion about this? Are there people lurking on this list who would be interested in attending a public 'user day' or even 'developer day' about the Osmocom cellular projects, with presentations and workshops around topics such as running Osmocom based cellular networks? In terms of when/where, I would suggest to keep the tradition of April in Berlin/Germany. But I'm of course very happy if somebody wants to host it some place else... Regards, and looking forward to meeting you [again] in 2017, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Moving from trac to a single redmine
by Holger Freyther 25 Sep '16

25 Sep '16

Hi guys, I think some of us would like to move to redmine and start using public tickets more frequently. So in case we move there are some topics to be discussed and I would like to start with a couple of them right now. Tickets: Redmine has a global linear sequence of ticket numbers. If we move from many tracs to a single redmine we can either: * not import tickets * only import from one project * deal with changing ticket numbers In terms of installations the GMR trac is broken in regard to tickets, there are some for SDR that are probably not being fixed anytime soon, baseband might be relevant and OpenBSC is unlikely to be relevant. I don't think we have ever used ticket reference in OpenBSC commit messages so in terms of OpenBSC having changing ticket numbers would not be a big deal. E.g. we could add a custom field with the old trac number? Wiki: We have external references that should be redirected to the new place. Is there any way besides maintaining a list in the apache2/nginx configuration and making redirects as we find broken references? Can we proactively manage this? Is anybody willing to come up with a script and nginx configuration for doing this? kind regards holger

Time to rename projects.osmocom.org to osmocom.org
by Holger Freyther 27 Mar '16

27 Mar '16

Hi, I think we all liked tnt's proposal to just call it osmocom.org. Are we ready to make the redmine available as osmocom.org (and redirect www.osmocom.org, projects.osmocom.org to it)? As first step of redirects I propose: http://bb.osmocom.org/ -> http://osmocom.org/projects/baseband http://openbsc.osmocom.org/ -> http://osmocom.org/projects/openbsc http://tetra.osmocom.org/ -> http://osmocom.org/projects/tetra http://simtrace.osmocom.org/ -> http://osmocom.org/projects/simtrace http://security.osmocom.org/ -> http://osmocom.org/projects/security http://gmr.osmocom.org/ -> http://osmocom.org/projects/gmr http://sdr.osmocom.org/ -> http://osmocom.org/projects/sdr any objections or corrections to that? kind regards holger

Hi all, I think we are close to the point of no return. All tickets and wikis have been imported. Please have a quick look if there is something obviously broken and if not I will proceed with post-processing and renaming tonight. kind regards holger

Hi All, After long long struggle, I have successfully installed OsmocomGmr. For ease of others, I want to share my experience, My OS is Ubuntu - 12.04 I have find following link for gnuRadio installation, it is very well written document. http://www.orbit-lab.org/wiki/Documentation/GNURadio/InstallationOnUbuntu12… This document guided me how to install UHD / GNU Radio and other stuff in 6 step. Software Installed are : UHD : release_003_005_002 GNU Radio : gnuradio-3.6.4.1 After Installation, I tested the connectivity of uhd / gnuRadio by following utilities: 1. uhd_find_devices 2. uhd_usrp_probe 3. gnuradio-config-info -v For testing of input signal I used uhd_fft utility, Signals were coming. I have usrp2 so i used following command for signal reception: ./gmr_multi_rx --gmr1-dl 802 -P /home/zia/Desktop/ --addr=type=usrp2 -a RX2 -S A:0 -T 10 Thanks, Zafar

[RFC] [ADMIN] Making lists subscriber-only?
by Harald Welte 15 Jan '14

15 Jan '14

Dear all, so far the osmocom.org mailing lists have always been in a 'non-members are manually moderated' mode. This has created a lot of work for manual list moderation, where a lot of the messages caught are simply spam, and only the occasional valid message is being received. I'd like to thank the list moderators for taking care of this. However, in more recent discussions, we were considering to move the lists to a completely closed mode, i.e. postings would automatically be rejected from non-members. The automatic response would contain a description of how to subscribe in 'nomail' mode, i.e. to subscribe in a way to be able to post to the list, while still not receiving any incoming traffic. The latter should be fine for occasional posters who don't want the bulk e-mail that goes with a full/regular subscription. Please provide feedback in case you disagree with that change. Unless there is major opposition, we will likely transition to the 'closed' mode within one month. Thanks, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
