After you setup an offline CA you usually wants to setup one or more online servers to publish certificates and CRL, receive requests and offers a lot of other services to your customers. To do so you have to install the necessary components plus a so called node interface. This node interface is used to manage the communication in the PKI hierarchy between the different servers and to manage the server itself. If you initialize such an online component then you have to use this node interface.
