Installation and Operations Manual
Telnet/SSH
The Telnet/SSH configuration page enables or disables Telnet and SSH support and configures the port
number that the Telnet or SSH server watches.
Enabling or disabling Telnet or SSH support:
Select Enabled or Disabled from the appropriate Server drop-down menu and click Apply.
Changing the Telnet or SSH server port number:
In the appropriate Port field, enter the port number and click Apply.
Enabling or disabling SSH server authentication methods:
The SSH server supports the Password and the Keyboard-Interactive authentication methods for security.
Password is an authentication method in which the SSH client gathers username/password credentials and
makes the authentication request to the SSH sever with the credentials. The Password method is controlled
by the SSH client.
Keyboard-Interactive is an authentication method in which the SSH server controls an information field
followed by one or more prompts requesting credential information from the SSH client. The client gathers
credential information keyed-in by the user and sends it back to the server. The Keyboard-Interactive
method is controlled by the SSH server.
Individual enabling and disabling of the Password and Keyboard-Interactive authentication methods are
supported to allow an SSH client to be forced to use a specific method. Although both methods are
available, by enabling the Keyboard-Interactive method and disabling the Password method, the SSH client
is forced to used Keyboard-Interactive, which is required to display the login banner.
NOTE: At least one authentication method must be enabled.
Select the Password checkbox and/or the Keyboard-Interactive checkbox and click Apply.
