Description The configuration of first-time authentication decides the action taken by the SSH
client when it accesses a server in the absence of the server’s public key:
■ With first-time authentication enabled, the SSH client can attempt to access the
server and get the server’s public key through negotiation. Then this public key
could be saved on the client for next access.
■ With first-time authentication disabled, the SSH client rejects to access a server. To
access the server, you must save its public key on the SSH client beforehand.
