Every SSH connection involves two types of authentication:

  • Server authentication

    For server authentication, the client verifies the identity of the SSH server. The SSH server authentication process uses the server's host public key to ensure that the SSH server is not an impostor.

  • User authentication

    For user authentication, the server verifies the identity of the user requesting access. The user authentication process uses the authentication methods specified in the server configuration file to verify the user's identity.

You enable the authentication methods by editing the server and client configuration files, as described in Chapter 3.

If your server also runs Kerberos for OpenVMS, you can enable Kerberos-based authentication, as described in Chapter 6.
