Use the ssh client first-time enable command to set the SSH client to perform 
the first-time authentication of the SSH server to be accessed.

Use the undo ssh client first-time command to cancel the first-time 
authentication.

The first-time authentication means that when the SSH client accesses the server 
for the first time in the case that there is no local copy of the server’s public key, 
the user can proceed to access the server and save a local copy of the server’s 
public key; when the client accesses the server next time, it uses the saved public 
key to authenticate the server.

If the first-time authentication is not supported, when there is no local copy of the 
public key of the connected server, the client assumes that the server is illegal and 
will refuse to access the server. The user can save a copy of the server’s public key 
locally by other means beforehand.

By default, the client does not perform the first-time authentication.

# Set the SSH client to perform the first-time authentication of the SSH server to 
be accessed.
