I have a client server application written in C for Linux.
Here the authentication is done using SSL.
I have to test whether my server is vulnerable or not.
But I am not getting as to how my client will specify the ssl versions while connecting to server.
There is some openssl commands where we can specify sll v2 or v3.
openssl s_client -connect IP:PORT -ssl3
openssl s_client -connect IP:PORT -ssl2
To which server will these command connect to?
Is it possible that openssl_s client will connect to my server daemon using ssl?
