STEP 5
Establish SSH sessions to the device from a SSH client application such as
PUTTY.
SSH User Authentication
Use the SSH User Authentication page to enable SSH user authentication by
public key and/or password. For a user using public key to establish an SSH
server, its user name and public key must be entered into the SSH User
Authentication Table. For a user using password to establish a SSH session, the
user name and password must be that of a user that has management access.
Before you can add a user, you must generate an RSA or DSA key for the user in
the external SSH key generation/client application (such as PuTTY).
Automatic Login
If you use the SSH User Authentication page to create an SSH username for a user
who is already configured in the local user database. You can prevent additional
authentication by configuring the
Automatic Login
feature, which works as
follows:
•
Enabled
—If a user is defined in the local database, and this user passed
SSH Authentication using a public-key, the authentication by the local
database username and password is skipped.
NOTE
The configured authentication method for this specific management
method (console, Telnet, SSH and so on) must be
Local
(i.e. not
RADIUS
or
). See
for more details).
•
Not Enabled
—After successful authentication by SSH public key, even if
the username is configured in the local user database, the user is
authenticated again, as per the configured authentication methods,
configured on the
Management Access Authentication
page.
This page is optional. You do not have to work with user authentication in SSH.
