It indeed does open a connection - because it wants to register with a NameServer. This is basically a bootstrapping-problem. You have to somehow distribute object references to connect clients to servers. You can do so by using persistent IORs and configure these for the client. You can also place them on a network-location somehow. Or you can configure a name-server for your ORB, and if that name-server is the same for the server, you can look-up an object reference there. This is what the example-code tries to do. So - the easiest solution for now would be to start the omniORB nameserver. On my ubuntu, that's a matter of installing it via apt.
