pysim-shell: export is missing some files
by Riemer, Björn 10 Nov '21

10 Nov '21

Hi, i recently noticed that the `export` command from pysim-shell is failing on some basic files like EF.ICCID. However if i manually select the file it can be read. This happens on a generic USIM and on the orange sysmousim-SJS1. see the logs below to illustrate. Cheers Bjoern sysmo usim: <..snip..> ################################################################################ # Export summary # ################################################################################ # total files visited: 165 # bad files: 75 # MF/EF.DIR, string indices must be integers # MF/EF.ICCID, string indices must be integers <...snip...> pySIM-shell (MF)> select EF.ICCID "621e8202412183022fe2a506c00100ca01808a01058b032f06048002000a8800" pySIM-shell (MF/EF.ICCID)> read_binary_decoded { "iccid": "8988211000000169394" } ------- KDDI USIM: Using PC/SC reader interface Waiting for card...

enabling ssh on nano3g s8
by Erich Dachleger 06 Nov '21

06 Nov '21

Hi all,Is there some special routine for enabling ssh on nano 3gs8 device?Or is the unit "useless" if the ssh-daemon is not running?(I have no way of seeing whether or not it is running) I can access by telnet to dmi interface, the telnet commands from the wiki are present and have read the docs from accelerate 3g but I think there might be some subtle info I miss regarding starting ssh. Port 22 is blocked is the errror message I get and i also tested the aes-method suggested in the wiki, same error, port 22 blocked also in that case. Could this be the situation where one has to try setting up a tr069 server? Regards /erich

USA or Mexico alternative to OsmoDevCon?
by Mychaela Falconia 05 Nov '21

05 Nov '21

Hello fellow telecom hackers, Seeing that OsmoDevCon 2022 is being discussed, I would like to propose a more inclusive alternative, to be held in either USA or Mexico. There are two severe lack-of-inclusion problems with OsmoDevCon: 1) Since its very beginning, ODC has been exclusionary, limited only to Osmocom developers specifically, excluding those developers and tinkerers who work on non-Osmocom projects in the "indie" telecom space, "indie" being defined as independent of major commercial vendors and industry. I hold the opinion that all monocultures are bad in principle, and an Osmocom monoculture is no better than, say, a Microsoft monoculture. Osmocom is currently in the dominant position, outweighing all others by some orders of magnitude, but might does not make right, and we need more diversity. We need more players in this niche space than just Osmocom! 2) The recent decision to limit OsmoDevCon only to those who have agreed to put a certain class of pharmaceutical into their bodies, *on top* of the Osmocom-only restriction of the previous paragraph, makes the proposed conference even more exclusionary and therefore of no service to the wider telecom hacker community. Of course it is not my place as a Russian-American to try to tell EU countries whom to allow or not allow within their borders, nor is it my place to tell private individuals like our Fearless Leader Harald whom to allow or not allow in their private spaces. But what I *can* do instead is to step forward and offer to organize and host a more inclusive alternative, and that is what I am doing with this post. Specifically I am offering to organize and host a physical in-person gathering of telecom (all telecom, not just wireless) hackers, enthusiasts and tinkerers, very similar in spirit to OsmoDevCon, but more inclusive: 1) Welcoming everyone who has devoted a major portion of his or her life to *any* project in the indie telecom space, regardless of which domain that project is hosted under, and regardless of whether that project is FOSS or merely PSS. (PSS = Published Source Software, a superset of FOSS.) 2) Welcoming everyone regardless of personal medical choices - what you do with your body is your business, not mine - you don't tell me what I should or shouldn't put in my body, and I won't tell you what you should or shouldn't put into yours. Also no forced testing: if you wish to get yourself tested for this or that before attending, it is your sovereign choice to do so, but no one will *ever* be turned away from an event which I organize and host, neither for refusing to test nor for any other reason. If there is anyone interested in such an inclusive in-person gathering of telecom hackers, I am offering to host one in my part of the world. Where is it geographically? I live in USA, near San Diego, and right next to the border between USA and Mexico. Depending on who is interested in joining and where they will come from, I can host our InclusiveDevCon on either side of the border, i.e., either in USA or in Mexico. It is my understanding that gaining entry into Mexico is much easier than gaining entry into USA, hence for that reason I suggest that we hold our get-together on the Mexican side of the border. If we do choose Mexico as our host country, the specific location will need to be in the northern part of that country, specifically in the Mexican state of Baja California; the candidate cities would be Tijuana or Ensenada, somewhere close to the border with USA. However, if the only people who are interested in joining either already live in USA or can easily enter this lovely country, then holding our Inclusive- DevCon in USA would make more sense - in that case it will be somewhere in San Diego area. Alternatively, if there is anyone in the community who shares my stated values of wider inclusion but cannot or does not wish to travel to USA or Mexico, if you would be willing to host an inclusive event in your part of the world, then I will consider traveling to attend your event - but *only* if your event is open to non-Osmocom PSS developers *and* open to those who refuse injections. Please note, however, that I cannot enter Russia - other parts of the former USSR including Transnistria are potentially accessible to me, but not Russia - I was born there, but I permanently lost the ability to visit my birthplace as a result of having done my gender transition while living in USA, with all steps for legal name and gender change done under the American system, as opposed to Russian.

Catching missing #include of <endian.h>
by Vadim Yanitskiy 01 Nov '21

01 Nov '21

Hi list, today I fixed a header file in libosmocore: https://gerrit.osmocom.org/c/libosmocore/+/26044 TL;DR, using OSMO_IS_{LITTLE,BIG}_ENDIAN macros without including the <osmocom/core/endian.h> header leads to empty struct definitions, and thus weird compiler warnings like 'struct `foo` has no member `bar`'. We may want to catch missing #include of the <endian.h> automatically, so I wrote a simple script to check whether it is absent: https://gerrit.osmocom.org/c/osmo-ci/+/26045 Below is an example of using it: $ cd libosmocore/ $ verify_endian_header.sh $(find . -name "*.[hc]") File './include/osmocom/gsm/protocol/gsm_44_004.h' does not #include <osmocom/core/endian.h> What's still missing is the actual integration into the build verification process. I guess there is currently no easy way other than calling this script from 'contrib/jenkins.sh' of each project? P.S. I found out that we also have 'scripts/verify_log_statements.py' in osmo-ci.git, but we don't seem to call it anywhere?

GSMTAP messages not generated
by Mario Lucas 30 Oct '21

30 Oct '21

Dear All, I am running a GSM stack: osmo-stp smo-msc osmo-hlr osmo-bsc osmo-bts-trx osmo-trx-lms It seems that my transmitter is emitting radio-waves into air (osmo-bts-trx and osmo-trx-lms communicate with each other through ports 5702 / 5802 — pls see attached printscreen), however i could not make GSMTAP tracing. Osmo-bts-trx does not send GSMTAP messages to port 4729. In most recent version of osmo-bts, GSMTAP tracing is arranged through config file: bts 0 gsmtap-remote-host 127.0.0.1 gsmtap-sapi ccch I could not run the GSMTAP tracing even in previous verions of osmo-bts where you have to specify in synopsis when you call a program: /usr/bin/osmo-bts-trx -s -c /etc/osmocom/osmo-bts-trx.cfg --gsmtap-ip 127.0.0.1 I thought may be i am having some issues in stack components behind osmo-bts for example in osmo-bsc or behind and i tried to run virtual bts. When i tried to run osmo-bts-virtual GSMTAP messages were visible in wireshark (please see attached file osmo-bts-virtual), therefore bts-bsc communication is good. However I still could not figure out why my osmo-bts-trx does not send GSMTAP messages. Or would you advise what log might be helpful to see what i am doing wrong …. Thank you for your always helpful assistance -- Mario Lucas ---------------------------------------------------------------------- -- Mario Lucas

Osmocom redmine upgrade / Let me know if something broke
by Harald Welte 28 Oct '21

28 Oct '21

Dear Osmocom community, today we finally upgraded our redmine installation from the unmaintained 3.4.x to the latest 4.2.3. The upgrade had been overdue for years, but today we (actually, Kevin) finally managed to find out how to make the openid_provider plugin to work with modern rails 5.x. In any case, I'm just informing you in case there is some unexpected fallout. I've verified that at least the following appears working: * logging into redmine * openid authentication from gerrit.osmocom.org (also after logout/relogin) * graphviz rendering * mscgen rendering There could however still be unexpected problems, particularly in features such as * e-mail notifications from redmine * updating redmine issues via e-mail * git integration ("Closes: OS#xxxx") If you run into any troubles, pleas report to https://osmocom.org/projects/osmocom-servers or if that also fails, feel free to send e-mails.

nano3g 237A <apologies if this is a repost>
by Paul Atreides 27 Oct '21

27 Oct '21

Not sure if this is a repost, i just joined the list and i don't think i had confirmed my account when i sent it (the confirmation was in my spam). Anyways, not trying to be a bad list member. I just picked up this IPAccess model which supports band 2/5 and has the same housing as the other units on the accelerate3g5 project docs. I've been pouring over docs and trying a lot of network configurations in my home lab. I have the login information for the factory reset and can access the web gui on port 8089 during the reset process, but ssh and telnet DMI seem to be disabled. I've been fuzzing ports and i've tried static as well as DHCP for IP addresses. My thought was that if i point the nano3G to the IP of my osmo-hNodeB machine that it would at least stimulate the device and maybe i'd see some log messages in the HNodeB gateway, but so far i haven't seen anything in the logs. i've also tried abisip-find and that doesn't find anything. Wireshark shows basic 'who has' Layer 2 messages and also DHCP requests sent to 0.0.0.0, both from the nano3g. The nano3g does get an ip from my lab router and i can ping it. The LAN behind that router can also access the 0.ipaccess ntp server, but again no telnet DMI or ssh so i'm unsure where to go from here. Layer 1 seems to show nothing on the uarfcn in the web gui, so it seems that its not crossing all the right bridges. I will admit, i haven't run any other osmo network components for the network, but as far as i was reading the home nodeb gateway and ntp should be the only things necessary to at least start the process. Any insight on what to try next would be very helpful. Does anyone have experience with this model? thanks

Subscriber Auto Provision in new split stack OSMO-NITB version
by Justin 21 Oct '21

21 Oct '21

Hi Osmocom, May I ask if we have similar feature of auto provisioning of subscribers who are trying to camp to the network similar to auth-policy accept-all in osmo-nitb? Is the new version supports also the auto provisioning of subscribers? Regards, Justin Mark Repollo

Hello, im Using a default configuration for my osmo-bsc setup using B210. I managed to get a working amplifier with specifications below. My question is, what should be the best config that i should use in order to maximize tge power and range of my amplifier? What are the best configs for osmo-trx, osmo-bts, and other applications related to osmo-bsc. Proper settings such as osmotrx tx-attenuation, nominal power, ms max power and other related configurations that are valid or matched for my amplifier. Listed below is my amplifier's specification. AMPLIFIER SPECS: band: uplink 885-915MHz / downlink 930-960MHz Max output power: downlink 47±1dBm Max allow input power: uplink -10dBm / downlink +10dBm gain: Uplink 25±2dB Downlink 28 to 53±1dB ALC: Uplink ≥10dB Downlink ≥10dB SWR: Uplink ≤1.5 Downlink ≤1.5 Passband ripple: Uplink ≤2dB Downlink ≤2dB Noise floor: uplink ≤2dB third order intermodulation: Uplink ≤-55dBc@-8dBm/ch/2ch Downlink ≤-36dBc@2ch Voltage: 28V Currency: ≤4.5A Thanks a lot!
