Are you talking about sniffing USRP
data? Gnuradio doesn't have "packets" -- it only knows about raw
samples. If you're using a USRP, UHD will packetize those samples
on their way to/from the hardware; we use the VITA 49/VRT protocol
for this. You can use the VRT dissector found here:
https://github.com/bistromath/vrt-dissector ...to view those packets, although there's not a lot of information there aside from the samples themselves. Alexander Chemeris and Ivan Kluchnikov put together a dissector for the control protocol N-series USRPs use, which can be found here: https://github.com/chemeris/uhd_dissector Hope this helps, --n On 03/21/2013 09:12 PM, Matt D wrote: -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone, Does anyone know to sniff packets coming out of gnuradio? I am spinning my wheels trying to figure this out on my own. Is there some sort of sink that goes to an ip address or a USB port that will show up in wiresharks interface?
