Hi list,
Since getting Sylvain's transceiver to work with my C118, I started to look at scapy
and specifically the gsm-um code as another interesting tool in the fuzzer's arsenal.
I see that Laurent Weber's personal website,
http://0xbadcab1e.lu/scapy_gsm_um-howto.txt, where he apparently had posted some examples
and tips on playing with his code, is no longer available.
Does anyone have a copy of those instructions? Has anyone tried running gsm-um with the
TRX firmware? Any tips or pointers before I dive in?
Cheers,
Miguel

But isn't it possible also to use the weber-code with the standard
osmocombb-package,prior to the trx firmware? Since scapy was mentioned in some of the
first talks about osmocombb with the only caveat that there is not a nice integration with
scapy yet?
Also if you need the testcall functionality one possibly must use an earlier version of
openbts.

Thanks for the reply Erich.
I'm not really sure about that. I'm going to experiment a bit if I can find the
time this week.
I see the gsm-um python code mentions it is possible to send out the scapy packets using
udp, tcp and unix domain sockets, so I imagine it should be fairly easy to integrate with
openbts and osmocom, either using the trx firmware or the older "regular" layer1
firmware.
Anyone that has played around with this before have any tips?
Cheers

works for me using 'milenage' branch in https://github.com/zabbal/openbts-p2.8
I've ported testcall patches from previous version of openbts.

Thanks Max,
I'll take a look at that branch soon.
Offtopic: By the way, I'm looking forward to buying the um-TRX to play around with.
Is it still due to start shipping the new batch in July? Does the standard um-trx work
well with GSM or do we have to also purchase the clocktamer?
Cheers,
Miguel

The UmTRX comes standard with a high quality VCTXO (or optionally OCXO
IIRC) based clock source and supports GPS calibration.
No need for external clocking.

Yep, correct.
VCTCXO with GPS by default, OCXO for big batches per request.
External clocking is not needed in both cases.

Yes, planned shipping by July.
