Operation Manual – SSH
H3C S5500-EI Series Ethernet Switches
Note:
Besides password authentication and publickey authentication, SSH provides another
two authentication methods:
password-publickey: Performs both password authentication and publickey
authentication of the client. A client running SSH1 client only needs to pass either
type of the two, while a client running SSH2 client must pass both of them to login.
any: Performs either password authentication or publickey authentication. The
client tries publickey authentication first.
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.
V. Interactive session
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.
Note:
During interactive session, the client can send the commands to be performed by
pasting the text, which must be within 2000 bytes. It is recommended that the text
pasted be commands in the same view; otherwise, the server may not be able to
perform the commands.
If the text exceeds 2000 bytes, you can upload the configuration file to the server
and use the configuration file to restart the server so that the server executes the
commands.
