server verifies the public key. If the public key is invalid, the authentication fails;
otherwise, the server generates a digital signature to authenticate the client, and
then sends back a message to inform the success or failure of the
authentication.
IV. Session request
After passing authentication, the client sends a session request to the server, while the
server listens to and processes the request from the client. If the client passes
authentication, the server sends back to the client an SSH_SMSG_SUCCESS packet
and goes on to the interactive session stage with the client. Otherwise, the server
sends back to the client an SSH_SMSG_FAILURE packet, indicating that the
processing fails or it cannot resolve the request. The client sends a session request to
the server, which processes the request and establishes a session.
V. Data exchange
In this stage, the server and the client exchanges data in this way:
The client encrypts and sends the command to be executed to the server.
The server decrypts and executes the command, and then encrypts and sends the
result to the client.
The client decrypts and displays the result on the terminal.

1.2 SSH Server and Client Configuration Task List

Many devices can act as the SSH server and client. This document describes two
cases:
The H3C switch acts as the SSH server to cooperate with software that supports
the SSH client functions.
The H3C switch acts as the SSH server to cooperate with another H3C switch that
acts as an SSH client.
Complete the following tasks to configure the SSH server and clients:
