Specifying a Source IP address/Interface for the SSH client

This configuration task allows you to specify a source IP address or interface for the client to access the
SSH server, improving service manageability.

Configuring Whether First-time Authentication is Supported

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. When accessing the server again, the client will use the saved server
host public key to authenticate the server.
Without first-time authentication, a client not configured with the server host public key will deny to
access 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:
To do...
Enter system view
Enable the device to support
first-time authentication
Disable first-time authentication
For successful authentication of an SSH client not supporting first-time authentication, the server host
public key must be configured on the client and the public key name must be specified.
