I have a simple C ++ / Java Calc application with CORBA. The server is written in C ++, the client in Java. I use omniORBs omniNames as a name service.
I would like to run my omniNames and server on my localhost (Ubuntu) and run my client on Windows XP SP3 in VirtualBox installed on my localhost Ubuntu.
(I mean: I installed Ubuntu OS on my local host, and on Ubuntu I installed VirtuaBox with Windows XP SP3 "inside."
I finally did this and installed host-only optinon in VirtualBox using this: https://superuser.com/questions/429405/how-can-i-get-virtualbox-to-run-with-a-hosts- only-adapter themes. Now I have another problem. My client finally sees my server and can even connect to it and send him a message, but he has problems receiving a response from the server: (this time my application is a simple calculation):

Where 192.168.56.1 is the IP address for the VirtualBox host only. Please help :) In the example here, the response from the server should be 8 (because, as we all know, 2 * 4 = 8;)
OK friends, sorry to bother all of you :) I found the answer: I added these lines to my /etc/network/interfaces file:
allow-hotplug eth0 iface eth0 inet dhcp
