Configuring Whether First-time Authentication is Supported
When the device connects to the SSH server as an SSH client, you can configure whether the device
supports first-time authentication.
• With first-time authentication, when an SSH client not configured with the server host public key
accesses the server for the first time, the user can continue accessing the server, and save the host
public key on the client. When accessing the server again, the client will use the saved server host
public key to authenticate the server.
• Without first-time authentication, a client not configured with the server host public key will deny to
access the server. To access the server, a user must configure in advance the server host public key
locally and specify the public key name for authentication.
