[Discuss-gnuradio] how to test hydra

[rui qian]

Dear all
I have installed hydra-0.4 and gnuradio3.2.2 on two different machines.
and I use tunnel.py to test gnuradio3.2.2, This allows two machines to talk.
When I run the command:
# hydra-tunnel /opt/hydra/gr/share/hydra/sconf-1
to test hydra-0.4, it is executed successfully without error and
warning. However, ping fails always.
I don't know why. please tell me how to test and use hydra.
thank you!
