Before performing the following tasks, you must generate an RSA public key pair
(using the client software) on the client, save the key pair in a file named key.pub,
and then upload the file to the SSH server through FTP or TFTP. For details, refer to
"Configuring the Device as an SSH Client" on page 1928.
# Import the client's public key from file key.pub.
[Router] public-key peer Router001 import sshkey key.pub
# Specify the authentication type for user client002 as publickey, and assign the
public key Router001 for the user.
[Router] ssh user client002 service-type stelnet authentication-type
publickey assign publickey Router001
Configure the SSH client
# Generate an RSA key pair
Run PuTTYGen.exe, choose SSH-2 RSA and click Generate.
