Configuring a remote file server

You can import OS images, device drivers, and boot files into the OS images repository from the local system or from a remote file server. To import files from a remote file server, you must first create a profile that is used to authenticate the connection to the remote file server.

About this task

The following cryptographic algorithms are supported:

The following protocols are supported:

For SFTP public key authentication and HTTPS certificate validation, Lenovo XClarity Administrator validates that the remote file server’ certificate. If the server certificate is not in the trust store, you are prompted to accept the server certificate and add it to the trust store. For information about troubleshooting validation issues, see Server certification validation fails.

Procedure

To configure a remote file server, complete the following steps.

  1. From the XClarity Administrator menu bar, click Provisioning > Manage OS images to display the Deploy Operating System: Manage OS images page.

  5. Enter the server name, address, and port.
  6. For HTTP, HTTPS, FTP, and SFTP with basic authentication, enter a user name and password if authentication is required to access the server.
  7. For SFTP with basic authentication, click Validate Server Certificate to obtain the public key signature.
    Note: A dialog might be displayed informing you that the OS deployment process does not trust the public key of the SFTP file server. Click OK to store and trust the SFTP public key in the OS deployment trusted key store. If successful, the public key signature is shown in the SFTP Server Public Key Signature field.
  8. For SFTP with public-key authentication:
    1. Enter a key passphrase and password and select the key type if authentication is required to access the server.
    2. Click Generate Management Server Key to obtain the public-key signature.

    4. Select the The Management key was copied onto the server checkbox in XClarity Administrator.
    5. Click Validate Server Certificate to validate the public key signature.
      Note: A dialog might be displayed informing you that the OS deployment process does not trust the public key of the SFTP file server. Click OK to store and trust the SFTP public key in the OS deployment trusted key store. If successful, the public key signature is shown in the SFTP Server Public Key Signature field.
    6. Click Save.
  9. Click Save Server.
