server
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.
z
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 for use in subsequent authentications.
z
Without first-time authentication, a client not configured with the server host public key will be
denied of access to 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.
Enable the device to support first-time authentication
Follow these steps to enable the device to support first-time authentication:
To do... Use the command… Remarks
Enter system view system-view —
