Can't get expected result.
My TLS-Attacker version is 5.1.6. I use TLS-Attacker as a client to connect to an openssl server whose version is openssl1.0.1f. I modify the WorkflowTrace according to https://web-in-security.blogspot.com/2019/03/playing-with-tls-attacker.html and the concrete xml file (trace.xml) is shown below.
<Send>
<messages>
<ServerHello/>
</messages>
</Send>
<Receive>
<expectedMessages>
<ServerHello/>
<Certificate/>
<ServerHelloDone/>
</expectedMessages>
</Receive>

But I haven't got the same consequence.
The server:
The client:
So I want to ask for help about the reason and what I should yo do .Thank you!
You are sending a ServerHello message not a ClientHello message, this is why the server is (rightfully) complaining. ClientHello and ServerHello are two different messages in TLS.
