Configuring the SSH Server

The SSH server includes basic settings for authentication.

Note:

You must first generate the host key pair on the SSH Host-Key Settings page

before you can enable the SSH server.

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: 1-120 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.

Web – Click Security, SSH, Settings. Enable SSH and adjust the authentication

parameters as required, then click Apply. Note that you must first generate the host

key pair on the SSH Host-Key Settings page before you can enable the SSH server.
