Hi, Solomon and all,
I already have tried your suggest and that's OK but in this case I need a
third PC which accomplish the role of sniffer while the other two PCs
sending data traffic, because the third PC in monitor mode can't send nor
receive data traffic. This case have a drawback which is the third PC sends
802.11 beacon periodically therefore it puts undesired traffic in the two
PCs scenario. Is there any way that third PC don't send beacons?
By the reason mentioned above I tried to use only two PC with one of them
capturing 802.11 data traffic while send and receive data traffic. Thereby I
tried to use "prism" pseudo-interface instead of wlan0 interface in monitor
mode. Is it possible to capture 802.11 data packet without monitor mode?
BR,
Johnny
