That connects to the NameService that is configured in the omniORB
configuration file (or on the command line). The configured service
need not be on localhost.

The best way is to put the URI for the remote server in the omniORB
configuration file.

corbaloc and corbaname URIs should be given to orb.string_to_object,
not resolve_initial_references.

The :rir: bit means get the result from resolve_initial_references, so
these two lines of code have exactly the same effect:

  obj = orb.resolve_initial_references("NameService")
  obj = orb.string_to_object("corbaloc:rir:/NameService")

You could refer to a specific name service on a specific machine with

  obj = orb.string_to_object("corbaname::my.host.name")

but it is far better to use the configuration file.

Cheers,

Duncan.
