Re: [Discuss-gnuradio] TunTap Interace for GNU Radio IEEE 802.11 a/g/p module

[Wen Cui]

Hi Bastian,

Thanks for your wonderful project. I have the same question that bothers me a lot. I have tried to set up the TUN/TAP things many days but I still cannot get the result that you have got in your example video, such as getting some packets from or to another terminal.

I followed the nic.sh file and your replies to others in the mail list. I really want to know whether it is only related to the TUN/TAP setup thing or it is related to the gnuradio code. I don’t know how to figure out the setup problem of the transceiver and where is the good place to ask this question. If you'd like to give me a hint, I will really appreciate about that.

PC1:
//wireless card in PC1
Tap0, IP: 192.168.123.1 MAC: 12:34:56:78:90:ab
wls5, IP: 192.168.123.20 MAC: a8:96:8a:f6:d5:2e

//USRP connected the PC1 through Ethernet cable
enp10s0, IP: 192.168.10.100 MAC: 40:6a:7f:bc:f2:2f
USRP, IP: 192.168.10.5 MAC: 00:80:2f:0a:cf:68

PC2:
//wireless card in PC2
wlp8s0, IP:192.168.123.50 MAC: 74:e7:0f:34:42:ba

I did the same config code as nic.sh does in PC1 but with changed IP and MAC address. I also set the arp and route things in PC2.

After I turn the tap0 up in PC1, I cannot PING PC1 anymore through PC2, and vice versa. The PC1 can hear the ICMP request from PC2, but cannot reply for that.

Best regards,
Wen Cui
