Greetings,
We have embedded OpenSSL 1.0.2j in our application order to securely
communicate with a Java Servlet engine (such as Tomcat). Our application uses
SSLv23_method(), so I expect it to negotiate up through TLS 1.2 (right?).
A customer claims to have configured the web (app) server to only allow TLS 1.2
(by disallowing up through TLS 1.1), and says that the client code (which we
know is based on OpenSSL 1.0.2j) is nevertheless connecting using TLS 1.1. We
are setting up a similar environment internally to diagnose what's happening,
and I wonder if anyone has any advice on the "best" tool for "watching" the TLS
version negotiation when the connection is being established.
The client environment is Solaris 10. I'm obtaining the necessary privileges
to use the snoop command. Does anyone have any do's or don'ts for using snoop?
Thanks in advance!
