RSA Authentication of SSH

The following procedure authenticates an SSH client based on an RSA key using RSA authentication. This
method uses SSH version 2:
Step Task
1 On the SSH client (Unix machine), generate an RSA key, as shown in
Figure 43-9. Generating RSA Keys
admin@Unix_client#ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/home/admin/.ssh/id_rsa):
/home/admin/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/admin/.ssh/id_rsa.
Your public key has been saved in /home/admin/.ssh/id_rsa.pub.
2 Copy the public key id_rsa.pub to the Dell Force10 system.
3 Disable password authentication if enabled.
4 Enable RSA authentication.
5 Bind the public keys to RSA authentication.
Host-based SSH Authentication
Authenticate a particular host. This method uses SSH version 2.
To configure host-based authentication:
