Hello everybody, osmocom is down (sad) so I cant look for the answer
there. How do I tunnel the gnu radio into wireshark? is there a sink
that goes to an ip address or a usb port or something? I am stuck here
without the instructions on osmo.
Thanks,
Matt

My copy of the repo isn't terribly recent, but, from what I can see,
we're implementing a UDP socket in one of the op25 blocks to deliver
packets to Wireshark.
There are a couple of implementations of GNU Radio blocks that send data
over UDP or TCP, but we're not using them, probably because they are
more suitable for sending a stream of samples rather than packets.

So I have the patched wireshark up and the flowgraph running.
wireshark is telling me there are no interfaces to capture. I am not
doing something here?

The op25 code is sending UDP packets to 224.0.0.1 which probably should
show up on your primary external interface.
You should be able to capture on your that interface (e.g. eth0 or
wlan0) or on your loopback interface (e.g. lo) in Wireshark. If you
can't, you have a Wireshark problem (maybe permissions?).

The original way that we used was in the receiver after the P25 frames were received and
reassembled they were encapsulated and written to the Linux TUN/TAP interface. When
properly configured, this interface (typ. 'tun0') shows up as a standard interface
in ifconfig (and in the list of allowed network interfaces that wireshark can listen on).
Then later our repeater stuff added support for writing received frames to UDP, using UDP
port 23456. See file repeater/src/python/usrp_rx.py.
In response to this, Mike added a UDP option to the wireshark plugin - see this message:
