Hi,
Yes now it works but can not able to ping the Machines. I am using RFX400
daughter card and set 192.168.200.1 and 192.168.200.2 respectively on machine A
and B.
On machine A: # sudo ./tunnel.py --freq 423.0M --bitrate 500k -A TX/RX -v # #
in another window on A, # ifconfig gr0 192.168.200.1 On machine B: # sudo
./tunnel.py --freq 423.0M --bitrate 500k -A TX/RX -v # # in another window on B
# ifconfig gr0 192.168.200.2
I got the following outputs
ON MACHINE A after setting up the virtual ethernet by sudo ifconfig gr0
192.168.200.1:

You must now use ifconfig to set its IP address. E.g.,
$ sudo ifconfig gr0 192.168.200.1
Be sure to use a different address in the same subnet for each machine.

But i am not able to ping the two machines. The settings and parameters used
looks correct but ping does not work on either.

Try running it with root rights, i.e. "sudo ./tunnel.py". Also make sure
that the device actually
exists, run
"ifconfig tun0".
