SSH Terminal Service 777
By default, the server is compatible with the SSH 1.x client.
SSH Client Configuration The following sections describe the SSH client configuration tasks.
■ Set to perform the first-time authentication on the SSH server to be accessed
■ Specifying the public key of the server
■ Configuring the first-time authentication of the server
Starting the SSH client
Use this configuration task to enable the SSH client, establish the connection with
the server, and carry out interactive session.
Perform the following configuration in system view.
Specifying the public key of the server
Use this configuration task to allocate an existing public key to the client.
Perform the following configuration in system view.
Configuring the first-time authentication of the server
Use this configuration task to configure or cancel the first-time authentication of
the server performed by the SSH client.
The first-time authentication means that when the SSH client accesses the server
for the first time in the case that there is no local copy of the server’s public key,
the user can choose to proceed to access the server and save a local copy of the
server’s public key; when the client accesses the server next time, it uses the saved
public key to authenticate the server.
