Configuring Security Features

Configuring SSH Version 2 for Secure Communication

This section discusses how to configure a user to use SSH version 2 encryption.

This feature is only available for the following devices.

Password Protection

To configure simple password authentication for an SSH user, no SSH-specific configuration is

required. Simply configure a user by entering the following commands:

set user name=name password=on

newpass name=name

where name is a user name

Example

set user name=ssh-user1

newpass name=ssh-user1

Using a Public Key

To enable public key authentication and to associate a public key with a user, enter the following

command:

set user name=name loadkey=host:key

where

• name is the name of a user

• host is either an IP address or DNS name of a host running TFTP that holds

• key is the name of a file that contains the DSA public key. If your host’s implementation requires

a complete path to the file, specify the path here as well.

Example: set user name=secure loadkey=143.191.2.34:ssh-file
