Want to do paid work on Osmocom? sysmocom is hiring
by Harald Welte 31 Oct '17

31 Oct '17

Dear Osmocom community, I would like to point out that at sysmocom, we're currently (again) hiring [1]. If you happen to have an interest in open source cellular communications and are fluent in C language development, we would love to hear from you. sysmocom probably doesn't need any introduction here, but just in case: The company was founded by Holger Freyther and Harald Welte, two of the leading OpenBSC and Osmocom developers from the very early days of the project. Today we are responsible for by far the largest number of commits to the Osmocom GSM/3G infrastructure related git repositories. Among our current priorities are automatic testing for the GPRS PCU, generalization of the OsmoMGW media gateway, support for load-based hand-over, inter-BSC hand-over as well as various improvements on the lower layers of the GPRS protocol stack. We're very dedicated to the cause in furthering the capabilities of open source cellular infrastructure from 2G to 4G. We believe in working upstream, no open core or dual licensing. If you have an interest working with an enthusiastic, strong technical and dedicated team of Osmocom hackers, please don't hesitate to let me know, best by e-mail to jobs(a)sysmocom.de Thanks, Harald p.s.: I hope this kind of message is not disturbing to anyone. I think it is important to the Osmocom project to have more paid people working on the stack, so it is justified. The positions we are seeking to fill will work [almost exclusively] on Osmocom, so it's not a random job ad but in the very interest of Osmocom, and hence on-topic for this list.

Planning for OsmoCon + OsmoDevCon
by Harald Welte 14 Oct '17

14 Oct '17

[cross-post to many lists, please follow-up-to openbsc(a)lists.osmocom.org] Dear all, time is flying, and I would like to start early with discussions and planning about OsmoCon and OsmoDevCon in 2018. It helps to start early. Side note: We have some pending issues about the events from last year at http://osmocom.org/projects/osmo-dev-con/issues - I've incorporated them in the text below. == OsmoDevCon == For OsmoDevCon, I think it's easy: We keep it as-is. Same procedure as every year, which means: * same venue, same catering options * same concept of 'anyone contributing to Osmocom can apply for registration until all seats are taken' * same idea of inviting some few speaker[s] doing other FOSS mobile communications work to join us The parts that we need to change, IMHO: * don't reduce from 4 to 3 days like last year. Have full 4 days again * sort topics per day / half-day, i.e. have "GSM/UMTS Cellular Infrastructure" days for BTS/BSC/NITB/MSC/HLR/SGSN/GGSN & Co, but then have other days for other projects. This would enable people not interested in the [continued evolvement] of the cellular projects be able to skip those days, or to simply meet in an adjacent room for parallel hacking sessions/discussions * try to be a bit more structured with the schedule in general. The existing approach works for people who attend all the event all day long, but not so well for people with other plans / limited time Any further change requests or topics to discuss? Please note that Pablo Neira has offered to kindly host an OsmoDevCon in Seville (Spain). I've attended a number of netfilter workshops he organized there, and he's doing a great job! However, given the large number of attendees from Berlin (and Germany in general), I think this would make things more complicated, and more expensive for most attendees. If you disagree with that assessment: I'm open for having the discussion, I just thought it's more practical/economic to do it in Berlin. === 10 year Anniversary Party === Given that 2018 marks the 10 year anniversary of Dieter and me hacking with the Siemens BS-11 in 2008, I think the 2018 incarnation deserves some special celebration of some form. I have no concrete idea yet, but for sure we should so something, and it should be at/around OsmoDevCon. And for sure we should have a BS-11 around :) == OsmoCon == The public OsmoCon was welcomed and was a success. However, let's start this discussion with a review of last years event. === Registration === * Registrations came in way too late. Two weeks ahead of the event, we were considering to cancel it. And then within the last few days, we had to turn people down due to limited seating capacity * To make planning more reliable, we see on other option but to significantly raise the registration fee combined with an equally significant discount for early booking === Duration === * Many people requested multiple days rather than just one, in order to make more out of (long distance) travels. This is obvious, but as we had no idea how many people would attend at all (or if we have to cancel due to lack of attendance), planning multiple days in the first incarnation would have been high risk and a multitude of work * I would suggest to expand to two or even three days this week, possibly one days with tutorials and the other day with tech talks * Slightly less crammed schedule due to multiple days === Venue === We recognize this yearso venue was not the best option, due to * Bad ventilation in the basemenet * Difficult to find * No space next to the conference room where people can meet / hang out in parallel to talks (not everyone attends every talk) I still like the "understatement" of the venue. I'd prefer any hostel / non-profit / hackerspace / university over luxurious hotels any time. Going to an expensive venue means more or less automatically more expensive ticket fees, which again is more likely to exclude pure community members without a commercial activity related to Osmocom. So any future venue would ideally: * be able to hold slightly more people than this year * have a second room or large lobby in which people can meet for extended coffee breaks in parallel to some talks, as needed * be slightly easier to find (and we have to put up some signs outside and in the lobby) * have better WiFi and/or wired connectivity === Programme / Format === * less crammed over multiple days * some more "interactive" formats were requested, for users to provide feedback to developers * there was some discussion about topics / speakers in redmine last year, but not too much participation [until it was too late]. * I'd suggest a more formal CfP process with a submission deadline that allows us to publish a preliminary schedule long ahead of the event === Video Recordings === I think they were a big success, and it was a very big surprise that the CCC Video Operations Center was volunteering to help such a small and niche-interest event like OsmoCon. We should make sure that we can repeat this for 2018. == Dates / Frequency == Having OsmoCon and OsmoDevCon back to back becomes somewhat long, if OsmoCon is 2-3 days and OsmoDevCon is 4 days. Basically we're looking at a full week for those of you who would like to attend both events. But then, I think the number of people attending both events is actually not all that big. Without checking the details, I think not more than half of the OsmoDevCon attendees were attending OsmoCon. I would expect that tendency to remain or even increase. I still think it's good to keep them back-to-back. In terms of frequency, I would actually suggest we move to a 6-month cycle rather than a 12-month cycle. There's a lot of development going on at all time. I understand that not everyone is able to attend two events just on Osmocom, especially if it's a spare time / hobby type activity. That's ok, I think there's no problem with attending either of the two only, and catching up by video recordings and/or mail on the other. The qeustion is: Should that second event be developer-oriented or user-oriented? Or again both? Any comments here? Ok, that was a somewhat lengthy e-mail. Please make sure to provide any feedback you may have as early as possible, to increase the chances of your feedback being reflected in the planning.

Without that the user was expected to either patch the Makefiles or to get a toolchain with the arm-elf- prefix.

simtrace as a remote sim solution
by pozsy＠uhulinux.hu 01 Oct '17

01 Oct '17

Hi All, Just found this project which seems to be quite interesting to me. Tried to read through all the information on the project page before asking, but not everything is clear yet :) So what I would like to achieve is basically the man-in-the-middle (mitm) mode. I do not actually need to modify any communication on its way, all I would like to do is to have: a) the sim card in a reader connected to host (A), while b) the gsm module is connected to an other host (B) and relaying their communication back and forth through some IP network. I guess I would need two pieces of simtrace hardware for that, as well as firmware and software modifications. Now the questions :) - Do you think this could work with the current hw/fw design? - Has anyone done something similar in the past? - What would be the maximum network delay allowed? - Do you know of any alternative solutions for my needs? Would be great to hear from you. Thanks, Balazs ps: I would also be willing to pay for professional consultancy services on this topic.
