Configuring the device as an SSH client
SSH client configuration task list
Complete the following tasks to configure an SSH client:
Task Remarks
Specifying a source IP address/interface for the SSH client Optional
Configuring whether first-time authentication is supported Optional
Establishing a connection between the SSH client and server Required
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.
Follow these steps to specify a source IP address or interface for the client:
To do… Use the command… Remarks
Enter system view system-view —
Specify a source IP
address or interface
for the SSH client
• Specify a source IPv4 address or interface for the SSH
client:
ssh client source { ip ip-address | interface
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 }
Required
Select either approach
By default, an SSH client
uses the IP address of the
interface specified by the
route of the device to
access the SSH server.
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
