Operation

3 Configuring the first-time authentication of the server
Use this configuration task to configure or cancel the first-time authentication of
the server performed by the SSH client.
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 choose to 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.
Perform the following configuration in system view.
