Re: [Discuss-gnuradio] TUN/TAP PDU not working

[Mojtaba Mansour Abadi]

I think I found out the possible source of problem.

 

Toda I found out the following issues with “Packet Encoder/Decoder” blocks.

 

I replaced the  TUNTAP PDU block with a Wav File Source and Audio Sink blocks at the transmitter and receiver, respectively.

 

I noticed that always the receiver side must be executed after the transmitter side. Otherwise I cannot hear any audio.

 

Now I wonder how I can solve this problem.

 

BTW, I also tried to use the gnuradio tunnel.py example in /example/digital/narrowband; But it won’t work and it always give an error.

The other tunnel.py example in /examples/digital/ofdm, however, works fine. But still I cannot ping the machines.

 

Cheers.

 

Regards,
Mansour.

Did you bring up the interfaces?

 

Are the IP addresses of the tuntaps reachable with a ping from your PC?
