11.2.2 SSH servers basic Settings (Password Settings)

This section describes the settings required to use SSH servers function of the Switch. The user authentication method uses the same password authentication as telnet.

Points to note

The following shows an example of setting a password for a user account used to connect to SSH, and an example of setting a SSHv2 server to operate. If you do not need a SSHv1 for security-related reasons, limit SSH to SSHv2 versions.

Be careful to set a password when creating a logged-in user. This is because users who have not set a password cannot log in with SSH password authentication. For details about creating login users, see 10.1.3 Creating and deleting login users.

When a SSH client connects to the Switch for the first time, SSH client displays a fingerprint of the host public key and asks if it is correct. For details about how to display the host public key and fingerprint of the Switch, see 11.2.7 Checking the host public key.

3. (config)# line vty 0 2
