echo-client and echo-server on different physical machines, referencing echo.ref

[Keith Christian <keithchristian yahoo com>]

I recently downloaded and successfully compiled the echo example from 
orbit-docs.tar.gz on a Debian Sarge system.  The echo-client and 
echo-server tests ran fine.  (I don't see a version number, but the 
orbit-docs/examples/echo/Makefile datestamp is 2004-07-09 09:34:54.

Since the echo-client and echo-server ran OK on the same machine, the 
paragraph in this web page was interesting:

http://www.gnome.org/projects/ORBit2/orbit-docs/orbit/x182.html

<<<If you want to have fun now, compile orbit on a different machine, 
make echo-client on the different machine, move  echo.ref  from the 
first machine to the second and run echo-client: eh voila - 
client/server over tcp/ip with the same code that ran using unix sockets 
on a single machine.>>>

However, even after copying the echo.ref file as explained in the above 
web page, echo-client could not connect to echo-server.

Has this been fixed, or are there ways to troubleshoot this?  I'd like 
to experiment with echo-client and echo-server on different machines, 
I'm sure it's possible.

Thanks.
