Accton Technology ES3628C Switch User Manual


 
User Authentication
3-63
3
CLI – This example generates a host-key pair using both the RSA and DSA
algorithms, stores the keys to flash memory, and then displays the host’s public keys.
Configuring the SSH Server
The SSH server includes basic settings for authentication.
Field Attributes
SSH Server Status – Allows you to enable/disable the SSH server on the switch.
(Default: Disabled)
Version – The Secure Shell version number. Version 2.0 is displayed, but the
switch supports management access via either SSH Version 1.5 or 2.0 clients.
SSH Authentication Timeout – Specifies the time interval in seconds that the
SSH server waits for a response from a client during an authentication attempt.
(Range: 1 to 120 seconds; Default: 120 seconds)
SSH Authentication Retries – Specifies the number of authentication attempts
that a client is allowed before authentication fails and the client has to restart the
authentication process. (Range: 1-5 times; Default: 3)
SSH Server-Key Size – Specifies the SSH server key size. (Range: 512-896 bits;
Default: 768)
- The server key is a private key that is never shared outside the switch.
- The host key is shared with the SSH client, and is fixed at 1024 bits.
