Osmocom Mailing List re-organization
by Harald Welte 03 Mar '21

03 Mar '21

Dear Osmocom community, This topic has been past due for way too many years by now: A re-organization of our major mailing lists. I would like to propose the following changes. Pleas let me know if you have any comments or feedback. I'm aware that renaming will mean people have to update their mail filter rules, but I think we're long past the point where the names of some of our lists started to confuse users. == openbsc(a)lists.osmocom.org == * openbsc doesn't exist anymore since OsmoNITB, which is also obsolete * does already cover anything "Osmocom CNI" related * Proposed new name: osmocom-cni(a)lists.osmocom.org == osmocom-net-gprs(a)lists.osmocom.org == This date back to when GPRS was a highly experimental add-on to our GSM code base. This list should simply be merged with openbsc@ as osmocom-cni(a)lists.osmocom.org == simtrace(a)lists.osmocom.org == Historically was created to cover only the simtrace project. We should rename this to osmocom-simcard(a)lists.osmocom.org or something along those lines. I would like to suggest it covers * SIMtrace / SIMtrace2 hardware + firmware * pySim and related tools for working with SIM/USIM/UICC cards * any other information / discussion related to SIM/USIM/UICC cards, like OTA, ARA-M, ... == osmodevcon(a)lists.osmocom.org == This has been a private list for people attending OsmoDevCon I would like to open up list membership to the general public, and ensure it also covers the new OsmoDevCall. We could then have discussions regarding feedback, topics, scheduling, etc. on that list. Maybe rename it to osmocom-events(a)lists.osmocom.org instead? To differentiate: osmocom-event-orga(a)lists.osmocom.org should remain a private list related to organizational / administrative topics of those involved with organizing future events. == nextepc(a)lists.osmocom.org == Should have been renamed to open5gs(a)lists.osmocom.org quite some time ago, I simply forgot about it. My apologies. -- - Harald Welte <laforge(a)osmocom.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

remsim: SIM inventory, mapping by IMSI
by merlin.chlosta+simtrace＠rub.de 06 Feb '21

06 Feb '21

Hi everybody, we try to use remsim for sharing SIMs across teams (multiple locations). We already set up the basic SIM sharing in a VPN. From a usability perspective, we’d like to have something like a SIM inventory and select SIMs by ICCID/IMSI rather than slots. We drafted some over-the-top service with a simple web application. pySim reads available cards, sends them to the service and generates a config for bankd. Kinda works, not really nice though. So before going much further, we’d like to ask: * is there something similar already? * are there similar features planned, like * automatically reading ICCID, IMSI and sharing them through remsim service directly? * mapping by card properties (IMSI/ICCID) instead of slot maps? We found it challenging to preserve the mappings across reboots, as PCSC indices change. We might just use remsim wrong, so any thoughts and feedback welcome. Besides, do you see any major blockers? Like… sharing across locations doesn’t really make sense if plugging-in-and-out is required, and we’re not sure if e.g. connection issues would require that. Happy for any thoughts! Merlin

Laser Cut SIMtrace Case
by Nick 29 Dec '20

29 Dec '20

Hi all, Had some free time this afternoon so I put together a laser cut case for the SIMtrace (photos attached), It's just cut out of 2mm perspex, with openings for the cards, flexible SIM adapter, USB and 2.5mm jack. They open up from the top for changing the flexible SIM adapters and accessing the buttons / flashing, The designs are attached for anyone who has got access to a makerspace or laser cutter wants to make one, - *SimTrace_2mm_box_version_7.dxf *is the DXF for the design, should work with any cutting software, file is in MM - *Simtrace_Final.rld *is the RDworks layout with the logo in it (most low end lasers use this software) and it has the nesting & logo baked in (DXF does not have the logo embedded) - *Osmocom_Logo_No_Gradient.jpg* is an adjusted version of the Osmocom logo as the laser CAM software doesn't deal with gradients I'm not sure where the best place to put the files are, so others can make their own - on the SIMtrace page on the Wiki or in the Repo itself? Cheers, Nick [image: image.png] [image: SIMtrace.png]

simtrace2-remsim set-atr flag - code offer
by Leonard Hübner 26 Oct '20

26 Oct '20

Hey there SIMTrace-Community! In the context of my current project I needed to set the ATR, which the SIMTrace2(cardem firmware) sends to the SIM-Terminal. To this end I added a cli flag (--set-atr) to the simtrace2-remsim host software which takes an ATR and signals to the cardem firmware to use this ATR. The later functionality is already present and therefore I only implemented the cli flag and the string to hex transformation (using osmo_hexparse). Would you be interested in this code? If you are, how can I contribute it? It currently lives inside a git branch on my machine. Thank you very much for making the code freely available! Leonard Hübner

OsmoDevCon / COVID-19
by Harald Welte 04 Sep '20

04 Sep '20

Dear fellow Osmocom developers, as you all know, we've sadly had to postpone OsmoDevCon 2020 back in April this year. At the time, we discussed to re-visit the situation in October 2020. While legally it is no problem at all to host an event with ~ 20 participants in Berlin/Germany (specific regulations really only start from 50+ participants) - I'm not entirely convinced it would be the smartest move. Legality and public health regulations are only one part of the equation - common sense and profound care for the key members of our community for sure are more relevant considerations to me. I'm not 100% in favour and not 100% against. Hence, I would like to get your input. Should we a) try to get an event organized on-site in Berlin? We'd have to move to a larger venue than IN-Berlin with proper ventilation and sufficient space so we can keep physical distance, but I think that's manageable for sysmocom as organizer. b) simply postpone to 2021? I'm convinced the situation will not change significantly (in a positive way) until late April 2021, so it's not really a "solution" as it will likely mean we have to think of late 2021 or 2022. c) plan some kind of online conference? To be honest, I think this model works fine for events where a single speaker wants to give lectures to hundreds or thousands of participants. But OsmoDevCon is much more interactive. We could record or live-stream some talks or screencasts from home, sure. But that only captures one part of the event. We could also try to set a date for a collaborative mumble, or the like - for the "hallway track". What are your thoughts? Let's avoid cross-posting the discussion to all of the mailing lists and simply have it on openbsc(a)lists.osmocom.org.

Osmocom scheduled outage on *2020-07-19 9am CEST*
by Harald Welte 19 Jul '20

19 Jul '20

There is an urgent need to migrate our most important public infrastructure to a new server, and I will be doing that on *Sunday, July 19 2020*, starting about 9am CEST. The migration involves redmine (main osmocom.org website), jenkins, gerrit, git, and cgit. In theory, the migration should be quick. I would expect (significantly) less than one hour of downtime. However, we all know Murphys law. Services not affected are mail (including mailman lists), ftp, dns. So in case of doubt, we can still use mailing lists to communicate. In case anyone urgently needs osmocom source code on Sunday morning during the downtime: There are public mirrors available on github.
