Prepare the Private Key Before an Rsync Migration

You must prepare the Tenable Appliance tns user's private key before using it during rsync migrations.

Before you begin:

  • Enable SSH access for your Tenable Appliance tns user.

    Note: Tenable recommends generating RSA keys 2048 bits or greater.

To prepare your tns user's private key for use during the migration:

  1. Confirm your private key is in OpenSSH .key format.
  2. Confirm the .key file begins with Begin RSA Private Key.
  3. Copy the the .key file to a directory on Tenable Core.
  4. Run the following command to change the permissions of the .key file:

    chmod 400 <private_key>.key

    Tenable Core updates the file permissions.
