Re: [orbitcpp-list] Problem with running compiled code on two mac hines.

[Dan K. <dk...@ix...>]

OK.  One thing to worry about is the hostname embedded in the IOR.

Make sure both client and server can do
   ping `hostname`
and make sure they can each ping each other by those names,
since IORs often have hostnames rather than IP adrs embedded.
