Connect to the FluidFS Cluster CLI Using SSH Key Authentication

You can grant trust to a specific machine and user by performing an SSH key exchange.

1. Generate an RSA SSH key.
   NOTE:The following example uses the ssh-keygen utility. The steps to generate an RSA SSH key can vary by operating system. See the documentation for the respective operating system for more information.
   1. Log in to a UNIX/Linux workstation for which you want to use SSH key authentication.
   2. From the command line, enter the following command:

      ssh-keygen -t rsa

   3. Press Enter at the Enter file in which to save the key (/home/user_name/.ssh/id_rsa) prompt.
   4. Press Enter at the Enter passphrase (empty for no passphrase) prompt and again at the Enter same passphrase again prompt. An SSH key is generated at /home/user_name/.ssh/id_rsa.pub.
2. Copy the SSH key to your clipboard.
3. Log in to the FluidFS cluster CLI through SSH using a password.
4. Enter the following command, pasting in the copied SSH key:

   system administrators passwordless-access add-ssh-keys Administrator add-ssh-keys ssh_key

   Now you can use the following command to log in to the FluidFS cluster from the workstation without needing a password:

   ssh fluidfs_administrator_user_name@client_vip_or_name

   You can also use the following format to run commands from the workstation without needing a password:

   ssh fluidfs_administrator_user_name@client_vip_or_name cli_command
