The server responds. There is a new message here – one we haven’t talked about. The Certificate Request. The server is indicating to Jetdirect that it must send it certificate to the server to be validated. We are in good shape because Jetdirect already stored a certificate capable of doing Client and Server authentication. That is a good thing!

Here we have a TLS Alert indicating Unknown CA. Jetdirect is sending this message to the server. This means that Jetdirect performed some checks on the server certificate and couldn’t verify that it was trusted. In short – Jetdirect needs a CA certificate configured.
