RSA Authentication of SSH
To authenticates an SSH client based on an RSA key using RSA authentication, follow these steps. This
method uses SSH version 2:
Host-Based SSH Authentication
Authenticate a particular host. This method uses SSH version 2.
Step Task Command Syntax Command Mode
1 On the SSH client (Unix machine), generate an RSA key (Figure 28-11).
