The roadwarriors carol and dave set up a connection each to gateway moon
using EAP-TTLS authentication only with the gateway presenting a server certificate and
the clients doing EAP-MD5 password-based authentication.
In a next step the EAP-TNC protocol is used within the EAP-TTLS tunnel to determine the
health of carol and dave via the TNCCS 2.0 client-server interface
compliant with RFC 5793 PB-TNC. The IMC and IMV communicate are using the IF-M
protocol defined by RFC 5792 PA-TNC.
The first time the TNC clients carol and dave send their measurements,
TNC server moon requests a handshake retry. In the retry carol succeeds
and dave fails. Thus based on this second round of measurements the clients are connected
by gateway moon to the "rw-allow" and "rw-isolate" subnets, respectively.
