Re: [Discuss-gnuradio] Wireshark Help

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:

Hope this helps,

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?
Thanks,
Matt D
