8.7.4 Configuring the First Successful Login to Another Device
(Allocating an RSA Public Key to the SSH Server)
To configure the first successful login to another device on the SSH client, you need to allocate
an RSA public key to the SSH server before the login.
Context
If the first-time authentication is not enabled on the SSH client, when the SFTP client logs in to
the SSH server for the first time, the SFTP client fails to pass the check on the RSA public key
validity and cannot log in to the server.
Do as follows on the router functioning as an SSH client:

The public key is edited.
The public key must be a string of hexadecimal alphanumeric characters. It is automatically
generated by an SSH client. You can run the display rsa local-key-pair public command to
view a generated public key.
Step 5 Run:

NOTE
Before being assigned to the SSH server, the assigned peer RSA public key must be obtained from the SSH
server and must be configured on the SSH client. Then, the STelnet client client can successfully undergo
the validity check on the RSA public key of the SSH server.
