Hi all! Just in time before OsmoDevCon, I managed to releaes a new version of the SIMtrace firmware. The list of changes is quite extensive and should address a number of the reliability problems that people have experienced. The changes include: * don't activate pass-through and LDO supply for the sim card at the same time, leading in power leaking from simtrace into phones * fix a watchdog timer misconfiguration leading to occasional watchdog resets * fix detection of sim insert/removal * better VCC_PHONE detection * reduce the amount of debug logging on the serial console and replace it by statistics (count of bytes, overruns, parity errors, etc) * statistics can be read from the UART by pressing 't'. * no longer crash the simtrace firmware if no simtrace host program is running Using this v0.5 firmware and a pretty aggressiv program causing lots of traffic (hunz' simdump) on a cm3121 reader at card Fi(9) Di(4) ratio 64 didn't cause any lost bytes or SIMtrace resets for me anymore. Any feedback is appreciated.

Hello, I'm interesting of this device to sniff APDUs. Can we talk a bit more details? BR Krzysztof Z.

Loosing 1 byte on each chunk of URB transfer

by Myonium

Hi It seems to me that simtrace looses a byte between 2 URB transfers from the device. To trace the problem down, I wrote a little test-program, running the same APDU against the smart card. I’m using simtrace to trace the card on the HW level and at the very same time I trace on the PCSC layer of the OS. Of cause the 2 APDU traces should give exactly the same results. Surprisimgly I found that the simtrace is swallowing one byte between two URB chunks transferred. Please find below the 2 logs A.) PCSC trace, B.) simtrace output. In this example simtrace is missing 1 byte (“7F”) between the two URB chunks a.) and b.). This missing byte causes to scrow up the analyser (APDU number 5). The same problem occurs also between the next two URB chunks b.) and c.): This time a “00” gets lost ... etc etc. A.)

SIM Trace Appears to Stop Processing APDUs

by Jonathan Thomas

Environment: We have tested on three systems with both Ubuntu and OpenSUSE. Additionally, we have tested with both VMs and as a core system install. Software Installed: Installed the latest using the instructions from the user manual. Issue: With testing against all three of the SIMTrace modules we purchased we have found the trace appears to lock-up or freeze randomly through processing of the APDUs. Since the phone still functions properly I am assuming that the communication between the SIM and the phone are still intact, it is just an issue with the output to screen/file output. Has anyone else experienced this issue? We will try and flash the firmware, but since we saw this issue with all of the hardware we purchased we assumed there might be some other issue. Thank you.

sysmosim - Greencard

by Arjen Smit

Dear all, Hopefully this is the right list for some questions on the SysmoSIM (aka Greencard). I have set the PIN1, PUK1, PIN1, PUK1, ADM1, AUK1, ADM2, AUK2 using the non-standard APDU (80 D4 ..) successfully using the cyberflex-shell. Verification of CHV1 and CHV2 are fine as well. (A0 20 00 01 08 ...) However verification of ADM2 (which I need because I want to change the Authentication algorithm) A0 20 00 0B 08 30 30 30 30 30 30 30 30 returns status : 98 02 (no chv initialized). It looks like I use the wrong APDU sequence for verifying ADM2 (I tried some other sequences as well (e.g A0 20 00 0A .. to A0 20 00 0D ..) but no luck. My main question is : What APDU sequence is needed to verify ADM2 ? Secondary less important questions: -When thinking about AUK1, AUK2, what are these used for ? -Do the cards support 03.48 OTA specs (if yes, can the Kic, Kid be set ?) -Are there actually any specs of these cards available ? (google gives www.elektroda.pl/rtvforum/download.php?id=351846 which matches the ATR of the card, however this spec is of little use though). Thanks in advance for your help. /Arjen

What can be logged?

by Florian Borggräfe

Hello, i have a question about the functionality of the Osmoscon SimTrace hardware system. Can I log everything, also packets like silent SMS (https://en.wikipedia.org/wiki/SMS#Silent_SMS)? Thank you for your request. Flo
