[Discuss-gnuradio] bbn_80211b_tap.py with tcpdump or wireshark

[Jane Chen]

Hi all,

 

I ran the bbn_80211b_tap.py.  I used both tcpdump and wireshark to try to  capture the packets. However, it doesn't work.

 

My steps:

1. ./bbn_80211b_tap.py.

2.ifconfig gr0 192.168.111.2

3. tcpdump -i gr0 -e -X

 

I have no idea what's wrong.

 

Could anyone please help me to capture the 802.11 packets?

 

Thank you,

Jane
