To be able to decrypt SSL traffic with Wireshark, you need to have the private key of the certificate that is presented in the Certificate message (which is being sent after the ServerHello). In your case this would be the private key of the certificate with the common name of TEST. This private key is stored on the server that you make a connection to.

I have not used IBM ikeyman, so I can't help you there unfortunately...
