Configuring Whether First-Time Authentication Is Supported - HP 6125G Configuration Manual

Step
1. Enter system view.
2. Specify a source IP
address or interface for
the SSH client.

Configuring whether first-time authentication is supported

When the switch acts as an SSH client and connects to the SSH server, you can configure whether the
switch 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 refuse to
•
access the server. To enable the client to access the server, you must configure the server host public
key and specify the public key name for authentication on the client in advance.
Enabling the switch to support first-time authentication
Step
1. Enter system view.
2. Enable the switch to support
first-time authentication.
Disabling 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.
To disable first-time authentication:
Step
Enter system view.
1.
2. Disable first-time
authentication support.
3. Configure the server host
public key.
Command

interface-type interface-number }
•
Specify a source IPv6 address or interface for the
SSH client:
ssh client ipv6 source { ipv6 ipv6-address |
interface interface-type interface-number }

Remarks
N/A
Select either approach.
By default, an SSH client
uses the IP address of
the outbound interface
defined by the route to
the SSH server to access
the SSH server.
Remarks

Optional.
By default, first-time authentication
is supported on a client.
Remarks

By default, first-time authentication
is supported on a client.
The method for configuring the
server host public key on the client
is similar to that for configuring
client public key on the server.
