testing ORBit2-2.7.0

[Sergio PérezAlcañiz <serpeal disca upv es>]

Hello, I'm new in the CORBA world and I just wanted to test the
echo-client/server program that is located in the test directory
/ORBit2-2.7.0/test#. 

Executing echo-server and echo-client in the same machine is no problem, but
when executing echo-client in a different machine the result is this:

./echo-client
IOR: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

** ERROR **: we got exception IDL:omg.org/CORBA/COMM_FAILURE:1.0 from echoString!

aborting...

Sure that COMM_FAILURE is due to the fact that the client cannot communicate
with the server, but why???

Executing ior-decode-2 shows this:
./ior-decode-2
