Usage Guidelines

Usage Scenario

When an SSH client accesses an SSH server for the first time and the public host key of the SSH server is not configured on the SSH client, run the ssh client first-time enable command to enable the first authentication function. The SSH client then can access the SSH server and save the public host key on the SSH client. When the SSH client accesses the SSH server next time, the saved public host key is used to authenticate the SSH server.

Precautions

To log in to the SSH server successfully at the first time, you can also run the ssh client assign command to pre-assign a public host key to the SSH server. When you use STelnet or SFTP to connect to the server, you need to specify the public key authentication algorithm for server authentication as the ECC, RSA, or DSA key algorithm.
