Hi, We tried to test the SSHD with OpenSSH as peer, using the "ecdh-sha2-nistp384" key exchange, but it failed to establish connection. SSHD was the client and OpenSSH the server, and the OpenSSH closed the negotiation. If we used ecdh-sha2-nistp521 or diffie-hellman-group-exchange-sha256, then the connection was created.
We haven't (yet) checked what goes wrong in the negotiation, but if someone can either confirm or deny the interoperability with 384, it would be nice to hear. Thanks, Heikki Mattila
