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.
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.
■
You must perform necessary configurations on the SSH server for SSH clients to
access.
