[http://www.wireshark.org/ wireshark] is a popular Open Source protocol analyzer.  Among many
4
other protocols, it includes dissectors for the GSM Layer 2 (LAPDm) and 3 (04.08).

There also is a GSMTAP protocol dissector (not in wireshark mainline yet, available in our
7
git repository in {{{src/wireshark/gsmtap.patch}}}), which allows real-time capture and
8
decode of GSM protocol messages encapsulated in GSMTAP (which is in turn encapsulated
9
in UDP and IP).

11
So if you have a wireshark version with GSMTAP support, you can have realtime decode and
12
trace of GSM protocol messages.

The OsmocomBB [wiki:layer2] program sends GSMTAP packets to the localhost (127.0.0.1) address
15
of the loopback interface (lo).
