Yes, my network does not use encryption, but I did not
specify TMSI when using ccch_scan.
And, what if I use lots of phones(e.g. 8 or more) to sniff per ARFCN? Will
I capture all the message sent by myself?
Dear Swift,
The gsmmap branch that you are using was created to allow users
to submit their own traffic to gsmmap.org and it's not meant to
be used as a mass interception tool.
If you use ccch_scan _and_ specify your ARFCN _and_ specify your TMSI
_and_ your network does not use encryption, then you will probably be
able to see your SMS in wireshark. Please note that the TMSI may be
re-allocated by the network at any time.
To make testing easier I suggest you to use a second Osmocom phone
running the official mobile application/firmware and set the "stick"
option in the configuration, so the ARFCN will not change.
Cheers,
LM
