The default socket factory implementation performs a * three-tiered approach to creating client sockets. First, a direct * socket connection to the remote VM is attempted. If that fails * (due to a firewall), the runtime uses HTTP with the explicit port * number of the server. If the firewall does not allow this type of * communication, then HTTP to a cgi-bin script on the server is used - * to POST the RMI call.

You can use the {@code RMISocketFactory} class to create a server socket that + * is bound to a specific address, restricting the origin of requests. For example, + * the following code implements a socket factory that binds server sockets to the + * loopback address. This restricts RMI to processing requests only from the local host. + * + *
{@code

+ * return new ServerSocket(port, 5, InetAddress.getLoopbackAddress());

+ *
+ * public Socket createSocket(String host, int port) throws IOException {
+ * // just call the default client socket factory
+ * return RMISocketFactory.getDefaultSocketFactory()
+ * .createSocket(host, port);
+ * }
+ * }
+ *
+ * // ...
+ *
+ * RMISocketFactory.setSocketFactory(new LoopbackSocketFactory());
+ * }
+ *
+ * Set the {@code java.rmi.server.hostname} system property
+ * to a host name (typically {@code localhost}) that resolves to the loopback
+ * interface to ensure that the generated stubs use the right network interface.
