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, as described in Enable SSH Access.

  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.

What to do next:

• Perform your rsync migration, as described in Perform an Rsync Migration.
