Subject: Re: [Discuss-gnuradio] bbn_80211b_tap.py with tcpdump or wireshark
Are you getting any errors when you run bbn_80211b_tap.py? What
hardware (USRP, daughterboard?) are you using? What OS? I think the
tun/tap interface is only supported on Linux and some BSD's (I've only
tried under Linux myself). If you don't see anything over tcpdump, are
you sure there are 1 and 2Mbps packets nearby on the frequency you are
tuning to (if you don't specify one, the default is 2437MHz)? The
README.txt in the examples directory
gives some help on the options you
can specify. If you are able to get
bbn_80211b_rx.py to see packets with
certain options, make sure you use the same with
_tap.py.
