Hello，guys I use the official card reader， root@debian:/usr/bin# pcsc_scan Using reader plug'n play mechanism Scanning present readers... Waiting for the first reader...found one Scanning present readers... 0: HID Global OMNIKEY 6121 Smart Card Reader [OMNIKEY 6121 Smart Card Reader] 00 00 Sat Jul 15 14:24:05 2023 Reader 0: HID Global OMNIKEY 6121 Smart Card Reader [OMNIKEY 6121 Smart Card Reader] 00 00 Event number: 0 Card state: Card inserted, Unresponsive card, Because there are special symbols in the name of the card reader, so I set this in the bankd configuration file csv "1","0","HID Global OMNIKEY 6121 Smart Card Reader \[OMNIKEY 6121 Smart Card Reader\] 00 00" And set up bankd like this. osmo-remsim-bankd -i 192.168.2.128 -n 1 -b 1 Because my server has a fixed ip I put the simtrace2 link on the linux of client-st2, and set up client-st2.

I tried to make their link. osmo-remsim-apitool -m 1 1 0 0 Because I read the instructions, when linking 1 simtrace2, our client-id and client-slot need to be set to 0 When I link successfully, both bankd and client-st2 have wrong information. as follows 1987 DBANKDW INFO bankd_main.c:655 [000 CONN_WAIT_ID] Rx RSPRO connectClientReq(T=0, N='openstick', SW='remsim-client', VER='1.0.0') 1987 DBANKDW INFO bankd_main.c:442 [000 CONN_WAIT_ID] Changing state to CONN_CLIENT 1987 DBANKDW INFO bankd_main.c:619 [000 CONN_CLIENT] No slotmap (yet) for client C(0:0) 1987 DBANKDW INFO bankd_main.c:450 [000 CONN_CLIENT] Changing state to CONN_CLIENT_WAIT_MAP (timeout=10) 1987 DBANKDW INFO bankd_main.c:967 [000 CONN_CLIENT_WAIT_MAP] Error -2 occurred: Cleaning up state 1987 DBANKDW INFO bankd_main.c:442 [000 CONN_CLIENT_WAIT_MAP] Changing state to ACCEPTING TCP connection to server at 192.168.2.131:9999 DLINP NOTICE input/ipa.c:141 192.168.2.131:9999 connection done DRSPRO NOTICE ../rspro_client_fsm.c:127 RSPRO_CLIENT(bankd){REESTABLISH}: RSPRO link to 192.168.2.131:9999 UP DRSPRO ERROR ../rspro_client_fsm.c:297 RSPRO_CLIENT(bankd){REESTABLISH}: Event SRVC_E_KA_TERMINATED not permitted DRSPRO INFO ../rspro_client_fsm.c:302 RSPRO_CLIENT(bankd){REESTABLISH}: Destroying existing connection to server DRSPRO INFO ../rspro_client_fsm.c:307 RSPRO_CLIENT(bankd){REESTABLISH}: Creating TCP connection to server at 192.168.2.131:9999 I'm wondering if I'm doing something wrong?

osmo-remsim-client-st2 tries to contact bankd at 127.0.0.1
by Adrian Popa 19 Jul '23

19 Jul '23

Hello everyone! I'm new to simtrace and I'm trying to set up a test with a Simtrace2 board connected to a RPI (which I'll call the client from now on) and a different RPI with an attached card reader (which I'll call the server). The server runs osmo-remsim-bankd and osmo-remsim-server (installed from your debian repo). The bankd server has its configuration csv file filled with the correct reader information. The osmo-remsim-server runs on the same machine and has a mapping configured via the python api tool to map client 1 to bank 1, like so: root@rpi-cardem-1:~# python3 /etc/osmocom/osmo-remsim-apitool -a /clients: {'clients': []} /banks: {'banks': [{'peer': 'B1', 'state': 'CONNECTED_BANKD', 'component_id': {'type_': 'remsimBankd', 'name': 'fixme-name', 'software': 'remsim-bankd', 'swVersion': '1.0.0'}, 'bankId': 1, 'numberOfSlots': 5}]} /slotmaps: {'slotmaps': [{'bank': {'bankId': 1, 'slotNr': 1}, 'client': {'clientId': 1, 'slotNr': 1}, 'state': 'ACTIVE'}]} The client runs osmo-remsim-client-st2 like this: root@rpi-cardem-2:~# osmo-remsim-client-st2 --server-ip remsim-server --server-port 9998 --client-id 1 --client-slot 1 --usb-vendor 1d50 --usb-product 60e3 --usb-config 1 --usb-interface 0 --usb-path "1-1.4" However, based on the logs, it tries to contact the bankd server at 127.0.0.1:9999 instead of remsim-server:9999: DRSPRO INFO ../rspro_client_fsm.c:307 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at remsim-server:9998 DLINP NOTICE simtrace2_api.c:271 [0] <= osmo_st2_cardem_request_config(features=00000001) DLINP NOTICE input/ipa.c:141 remsim-server:9998 connection done DRSPRO NOTICE ../rspro_client_fsm.c:127 RSPRO_CLIENT(server){REESTABLISH}: RSPRO link to remsim-server:9998 UP DRSPRO INFO ../rspro_client_fsm.c:307 RSPRO_CLIENT(bankd){REESTABLISH}: Creating TCP connection to server at 127.0.0.1:9999 DRSPRO NOTICE ../rspro_client_fsm.c:127 RSPRO_CLIENT(bankd){REESTABLISH}: RSPRO link to 127.0.0.1:9999 DOWN The bankd server listens on 0.0.0.0 on the server side: root@rpi-cardem-1:~# netstat -tpan | grep osmo | grep LISTEN tcp 0 0 0.0.0.0:9997 0.0.0.0:* LISTEN 409/osmo-remsim-ser tcp 0 0 0.0.0.0:9998 0.0.0.0:* LISTEN 409/osmo-remsim-ser tcp 0 0 0.0.0.0:9999 0.0.0.0:* LISTEN 405/osmo-remsim-ban My question is - how is osmo-remsim-client-st2 getting the IP address of the bankd server? What did I do wrong? I've tried a few tricks to redirect traffic from 127.0.0.1:9999 to remsim-server:9999, but so far have failed. This is what I've tried as a proxy, but the connection seems to get garbled because netcat expects LF terminated strings: nc -l 127.0.0.1 9999 | nc remsim-server 9999 Thanks for the help Cheers, Adrian

Some questions about osmo-remsim-bankd
by bianfang85＠163.com 17 Jun '23

First of all, I installed osmo-remsim-bankd, server, and client-st2 on different virtual machines through the binary package. I inserted the officially purchased card reader and can also read my card

First of all, thank you very much for being so busy and being able to reply to my question of being so mentally challenged. Haha I have tested and found that there may have been some issues with my PCB production, and I have also identified the cause. As shown in Figure 1,[cid:image002.jpg@01D993BA.F5F9A8C0] Through this flywire, I successfully flushed in the required firmware program. Both lights are on, which makes me very excited.[cid:image005.jpg@01D993BA.F5F9A8C0] I linked the firmware and installed the dfu driver under Windows, but the result showed this[cid:image007.png@01D993B3.AA7A4870] I have tried several dfu drivers, and there is a yellow exclamation mark below this icon! At this point, I saw that there was a simtrace in the USB device on my vmbox. I don't know if this is considered a success. I can only continue to try.[cid:image010.jpg@01D993BA.F5F9A8C0] [cid:image011.png@01D993B4.AAF416E0] Can find the current device. I entered the osmo remsim client st2 command according to the user manual I have carefully read the manual, but I am still confused as to which part I should start with. Can you give me a simple idea? Do I first set up the card reader section, then the server section, and finally the simtrace2 section?[cid:image012.png@01D993BA.F5581190] 从 Windows 版邮件<https://go.microsoft.com/fwlink/?LinkId=550986>发送

https://gitea.osmocom.org/sim-card/simtrace/src/branch/master/hardware/pcb/… I am a novice Xiaobai, I am very interested in this project. So I made the pcb by myself, according to the content of the website above. But I can't get it into the program, which annoys me. I don't know if it's my hardware that's wrong. It's still a problem with my software. I hope that the teacher who understands can help me check it out, thank you very much here.

Call for Help: Test data from SIM cards for pySim-shell decoder unit tests
by Harald Welte 29 Jan '23

29 Jan '23

Hi all! I'm currently adding unit tests for the various pySim encoder/decoder classes for the variouus SIM/UICC/USIM/ISIM files. [1] In order to increase the test coverage, I would appreciate any help in obtaining test data, particularly for the more "exotic" (or recently introduced) files, related to DF.5GS, ADF.ISIM or even DF.WLAN or the like. So if you have any SIM cards with related files populated, I would appreciate some test data. You can simply send me a copy+paste of the respective 'read_binary' / 'read_records' command, or a partial 'export'. In the latter case, please make sure to redact/remove your IMSI/ICCID/MSISDN/Kc data to prevent leaking privacy related information. Thanks in advance.

Hello, Recently I acquired a SIMtrace2 card unit with ATSAM3S in order to build a P.O.C. of the communication of the SIM card and the modem remotely, but I could not make the application to communicate via USB with the SIMtrace2. I followed this steps (all of them) https://osmocom.org/projects/simtrace2/wiki/Cardem After I run this command: osmo-remsim-client-st2 --usb-vendor 1d50 --usb-product 60e3 --usb-path 1-2.2 --usb-config 1 --client-id 1 --client-slot 1 --server-ip 127.0.0.1 --server-port 9998 -d DMAIN,1:DST2,1:DRSPRO,1 I'm stuck in this error (even running as sudo): DMAIN DEBUG fsm.c:456 CLIENT_MAIN(main){INIT}: Allocated DRSPRO DEBUG fsm.c:456 RSPRO_CLIENT(server){INIT}: Allocated DRSPRO DEBUG fsm.c:456 RSPRO_CLIENT(server){INIT}: Allocated DRSPRO DEBUG remsim_client_main.c:185 RSPRO_CLIENT(server){INIT}: Received Event SRVC_E_ESTABLISH DRSPRO DEBUG ../rspro_client_fsm.c:355 RSPRO_CLIENT(server){INIT}: state_chg to REESTABLISH DRSPRO INFO ../rspro_client_fsm.c:308 RSPRO_CLIENT(server){REESTABLISH}: Creating TCP connection to server at localhost:9998 DMAIN ERROR user_simtrace2.c:430 can't open USB device Additional information: - Host S.O.: Debian 10 armhf. Also tried on Ubuntu 22 x64 - I've tried to recompile software following `Get and compile the software`, but these steps really doesn't work. Then I tried aclocal, autoconf, automake --add-missing & ./configure but nothing of them can rid of the error: cannot find input file: `include/Makefile.in' - SIMtrace2 firmware: $ sudo simtrace2-list USB matches: 2 1d50:60e3 Addr=8, Path=1-1.3, Cfg=1, Intf=0, Alt=0: 255/2/0 (CardEmulator Modem 1) 1d50:60e3 Addr=8, Path=1-1.3, Cfg=2, Intf=0, Alt=0: 255/255/0 (0.8.1.58-773d) Sorry if this issue was addressed in another email, I even tried looking in the archives but the archives page is not very user friendly. Thanks for your support, Bruno Natali

Unable to complete ATR with remSIM
by Ken Andrews 17 Jan '23

17 Jan '23

Hello, I’m trying to get basic functionality working with remSIM but am stuck with a failure after what looks like an initial handshake. It appears that the client sees an error in the connectClientRes it receives from the server. For now I’m trying to keep things simple by running on a single (VMWare Fusion) Ubuntu 22.04 VM. I’ve noticed that your CI/CD test setup uses multiple VMs. Is this a requirement?

Hi Mychaela Can you tell me what the intent of the C1 capacitor is for? Previously when I probe the signals I just solder fly wires on to the SIM socket on the FPC, but this capacitor intrigues me. Thanks

Observing SIM voltages put out by various old phones
by Mychaela Falconia 01 Dec '22

01 Dec '22

Hello fellow SIM tracers, I just built this little gadget that allows one to observe (easily, safely, non-invasively) what voltages each given phone puts out toward the SIM: https://www.freecalypso.org/members/falcon/pictures/SIM-volt-test/sim-fpc-p… It is a trivial PCB adapter that connects together a SIM socket, an FPC connector that fits existing SIMtrace FPC cables, and a set of plain old 2.54 mm header pins exposing each signal on the SIM-ME interface. This adapter is purely passive, hence it doesn't need power, it does not contain any components that can be damaged by high voltages (in fact, there is not one ESD-sensitive component on this PCB!), and it does not introduce any Heisenbug effects into the SIM-ME interface under test. The usage scenario should be obvious: I insert a fitting SIMtrace FPC cable into the phone under test, the other end of that FPC cable plugs into my PCB, the SIM socket on my adapter is either filled with an actual SIM or left empty depending on the test to be performed, and I observe the voltage between GND and VCC pins. Here is that test being performed with a Nokia 2190E, one of the very first GSM phones sold in USA, circa 1995 or 1996: https://www.freecalypso.org/members/falcon/pictures/SIM-volt-test/N2190-tes… https://www.freecalypso.org/members/falcon/pictures/SIM-volt-test/N2190-tes… And here are some test results: * Nokia 2190E, PCS band equivalent of 2110, powered by a 5-cell NiMH battery: always puts out 5V toward the SIM. * Ericsson I888, powered by a 4-cell NiMH battery: likewise always puts out 5V toward the SIM (will probably be a little under 5.0V, but still within 5V spec, under low battery conditions), but I would not classify this phone as "Phase 1": it supports SMS, USSD, CSD via IrDA, and EFR speech codec. * Nokia 6190, PCS band equivalent of 6110 (first ARM-based GSM phone ever?), powered by a 3-cell NiMH battery: tries 3V first, if the SIM is "3V technology SIM" or "1.8V technology SIM", then the phone stays at 3V, but if there is no good ATR at 3V, then it tries 5V. If a phone is powered by a 3-cell NiMH or 1-cell Li-ion battery, then the only way it can put out 5V is by going through a boost converter, which are of course bad for battery life - thus it seems that once phones went to these lower-voltage batteries, then they started preferring 3V SIMs at the same time (while still supporting 5V SIMs in those days!), whereas phones powered by higher-voltage batteries (4 or more Ni-Cd or NiMH cells) keep it simple and always put out 5V, it seems. Now Nokia 2190E is a really finicky phone in terms of which SIMs it accepts: as the r/vintagemobilephones community on Reddit figured out, there is just one T-Mobile MVNO (LycaMobile) whose SIMs it accepts, while all others are rejected - and the worst part is, it rejects my current Themyscira SIMs too! (My SIMs are FCSIM1, equivalent of old sysmoSIM-GR2.) So what is so special about those LycaMobile SIMs which this phone accepts while rejecting all others? Examining that SIM in a card reader, I see nothing special, same deal as most operator-issued SIMs these days: native UICC/USIM/ISIM, has GSM 11.11 support for backward compat, GSM 11.11 SELECT on MF/DF indicates "1.8V technology SIM", ATR indicates all 3 voltage classes supported. Now that I have proven what I previously only suspected (the fact that this ancient Nokia always puts out 5V toward the SIM), SIMtrace2 is definitely out - however, I now also have a SIMtrace1 board, graciously donated by Kevin, and I am going to see if I can find some time to get SIMtrace1 software working and try sniffing Nokia 2190E to SIM comms in the working and not-working cases.
