Authentication will fail if the number of authentication attempts (including both
publickey and password authentication) exceeds that specified in the ssh server
authentication-retries command.
Complete the following tasks to configure an SSH client:
Task
"Specifying a Source IP address/Interface for the SSH client" on page 1928
"Configuring Whether First-time Authentication is Supported" on page
1928
"Establishing a Connection Between the SSH Client and the Server" on
page 1929
This configuration task allows you to specify a source IP address or interface for
the client to access the SSH server, improving service manageability.
To do...
Enter system view
Specify a source
IP address or
interface for the
SSH client
When the device connects to the SSH server as an SSH client, you can configure
whether the device supports first-time authentication.
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.
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:
Specify a source IPv4 address or
interface for the SSH client
Specify a source IPv6 address or
interface for the SSH client
