SSH Client Configuration Configuration prerequisites
Make sure that the SSH server is configured. Refer to “SSH Server Configuration”
for configuration details.
Configure the device as an SSH client
When a device operating as an SSH client connects to the server, you can specify
whether the SSH client performs first authentication for the SSH server to be
accessed.
■ With first authentication enabled, when the SSH client accesses the SSH server
for the first time, the user can continue to access the SSH server and the host
public key will be saved on the client even if the server host public key is not
configured on the client. When the SSH client accesses the SSH server next
time, the SSH client uses the host public key saved on it to authenticate the
SSH server.
■ If first authentication is not supported, the SSH client can not access the SSH
server if the server host public key is not configured on the client. Before
configuring a device as an SSH client, you need to configure the host public key
of the server to be accessed on the local device and specify the name of the
host public key file of the server to be accessed. Thus, the SSH client can
authenticate the SSH server to be accessed.
