Secure Shell Authentication
Secure Shell (SSH) is disabled by default.
Enable SSH using the ip ssh server enable command.
SSH supports three methods of authentication:
• Enabling SSH Authentication by Password
• Using RSA Authentication of SSH
• Configuring Host-Based SSH Authentication
• Using Client-Based SSH Authentication
Important Points to Remember
• If you enable more than one method, the order in which the methods are preferred is based on the
ssh_config file on the Unix machine.
• When you enable all the three authentication methods, password authentication is the backup
method when the RSA method fails.
• The files known_hosts and known_hosts2 are generated when a user tries to SSH using version 1 or
version 2, respectively.
Enabling SSH Authentication by Password
Authenticate an SSH client by prompting for a password when attempting to connect to the Dell
Networking system. This setup is the simplest method of authentication and uses SSH version 1.
To enable SSH password authentication, use the following command.
• Enable SSH password authentication.
