Dell PowerFlex Appliance with PowerFlex 4.x Administration Guide

Generate SSH key pairs (Optional)

To create the SSH keys for a PowerFlex node, switch, OS Admin, OS User, use this procedure to manually generate the SSH keys that is of RSA type and ensure the key is generated without pass phrase.

1. Generate a private key using the following command:
   ssh-keygen -b 2048 -t rsa
2. Enter a file path to save the public and private keys or proceed with the default file path without a pass phrase:
   Sample output:

   Enter file in which to save the key (/root/.ssh/id_rsa):
   Enter passphrase: # do not enter a passphrase
   Enter same passphrase again: # do not enter a passphrase

   Sample output that indicates the public and private keys are saved in the default file path:

   Your identification has been saved in /root/.ssh/id_rsa
   Your public key has been saved in /root/.ssh/id_rsa.pub
   The key fingerprint is:
   SHA256:fKIllqp5UXeuEW7xuYeE7PNHpvjAUatNx6I/bisRqRU root@PFMP2-4
   The key's randomart image is:
   +---[RSA 2048]----+
   |                 |
   |        E        |
   |         o.      |
   |      .oB..o     |
   |     .+*SO=.o    |
   |    .o.=BO=oo    |
   |    ...o=*.*     |
   |   o.   *o* o    |
   |  o.     B*=     |
   +----[SHA256]-----+

3. Verify that the public and private keys are saved in the default file path: /root/.ssh/.
   Sample output:

   cd /root/.ssh
   ls

   • id_rsa.pub indicates a public key.
   • id_rsa indicates is a private key.
