I have doing an analysis of IBM z/OS environment. I notice something very
strange. It seems that when I turn on decode to do SSL I get packets that are
indicated to be SSL/TLS but aren't.
I used NBA for Z/OS from Service Pilot to capture packets that I fed into
Wireshark.
The following shows a packet with SSL indicated:
