Using 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.
1. On the SSH client (Unix machine), generate an RSA key, as shown in the following example.
2. Copy the public key id_rsa.pub to the Dell Networking system.
3. Disable password authentication if enabled.
CONFIGURATION mode
no ip ssh password-authentication enable
4. Bind the public keys to RSA authentication.
EXEC Privilege mode
ip ssh rsa-authentication enable
5. Bind the public keys to RSA authentication.
EXEC Privilege mode
ip ssh rsa-authentication my-authorized-keys flash://public_key
Example of 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.
