z
password-publickey: Performs both password authentication and publickey authentication if the
client is using SSH2.0 and performs either if the client is running SSH1.
z
any: Performs either password authentication or publickey authentication.
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. After successfully processing the request, the server
sends back to the client an SSH_SMSG_SUCCESS packet and goes on to the interaction 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.
Interaction
In this stage, the server and the client exchanges data in the following way:
z
The client encrypts and sends the command to be executed to the server.
z
The server decrypts and executes the command, and then encrypts and sends the result to the
client.
z
The client decrypts and displays the result on the terminal.
z
In the interaction stage, you can execute commands from the client by pasting the commands in
text format (the text must be within 2000 bytes). It is recommended that the commands are in the
same view; otherwise, the server may not be able to perform the commands correctly.
z
If the command text exceeds 2000 bytes, you can execute the commands by saving the text as a
configuration file, uploading the configuration file to the server through Secure FTP (SFTP), and
then using the configuration file to restart the server.
