Hi,
I want to compare and test few network protocols using USRP1. I have two USRP1

Hi,
I posted my question a couple of days ago but could not get any response,
probably because it was an over-datailed mail. Here, I am just posting a part
of it,
Is there any problem if I do call benchmark_rx.py and benchmark_tx.py with
following command line arguments?
$ python ./benchmark
Hi,
I completed the installations and checked tone generation and benchmark_tx/rx
over a pair of usrp, along with usrp_wfm_rcv.py for or FM reception. These
examles ran pretty fine. Then I tried tunnel.py with command line arguments as
in README file:
./tunnel.py -f 423.0M --bitrate=500k

2- When I tried PINGing the second machine, an error appeared; 'Destination
Host Unreachable'. How to resolve this?

Hi,
I see a series of 'B' while running tunnel.py on one machine and this
