Or you can use a switch to connect those interfaces to. You will still need to manually configure the interfaces using a unique subnet. Will probably want to populate the /etc/hosts file on each system to specify the private address and associate that with a system name that you can use to transfer data over the private network. Do these systems use a common Internet connection through a router? If so they can communicate over that router through the currently active interfaces.
