+Two transport connections to gateway sun are set up, one from client
+carol and the other from client dave. The gateway sun uses
+the Trusted Key Manager (TKM) and is the responder for both connections. The
+authentication is based on X.509 certificates. In order to test the connections,
+both carol and dave ping gateway sun.
