    Description

      Connecting to a hardened Linux box using ECDSA is not supported.
      Elliptic Curve Cryptography (ECC) is gaining wider use due to increased computationally efficient. Ex. a 256-bit ECC public key should provide comparable security to a 3072-bit RSA public key.

      RFC 6239: Suite B Cryptographic Suites for Secure Shell (SSH)

      Connecting to host...
      SSH connection failure: SSH Protocol error: Server and client capabilities don't match. Client list was: ssh-rsa,ssh-dss.
      Server list was ecdsa-sha2-nistp256.
      
      Device test failed.
