Use the Remote Administration Client (RAC) software

This chapter describes how the Remote Administration Client can be used to participate in a quorum remotely.

Requirements

For all quorum members:

  • Remote screen sharing tools such as WebEx, VNC or RDP. Should be able to pass RDP session to each Smartcard holder in turn and make the presenter.

  • IPv6 link-local address with the interface, IPv6 address, IPv4 address or hostname to the Remote Administration Service.

  • Port number or numbers at which the Remote Administration Service accepts calls from Remote Administration Clients.

For the quorum member who will execute the HSM administration task:

  • Tool to connect from the local machine to the Remote Administration Service.

Use the RAC GUI to create an association with a dynamic slot

The wizard-based GUI consists of a series of dialogs that enable you to associate a TVD with the appropriate HSM using one of its Dynamic Slots.

When you are using the GUI, keep in mind the following:

  • If you click Exit, or close the RAC GUI at any time, you must restart the nShield Remote Administration Client and repeat all steps.

  • If you click Back on the Use Card Reader page, the slot on the HSM will be released for use by another card reader.

  • If the network connection is lost, an error message displays.

  • If you disconnect the TVD while using the nShield Remote Administration Client, an error message displays and you are returned to the Select Card Reader (step 3 of 3) page to select a new reader.

  • Windows 8.1+ only

    If you disconnect the TVD while you are on the Use Card Reader screen, the Windows Smart Card service SCardSvr displays an error and terminates.

  1. Launch the remote screen sharing tool that will be used between the quorum members.

  2. Start the RAC:

    • On Windows, double-click the Remote Administration Client icon.

    • On Linux:

      • Make sure the pcscd service is running.

      • Navigate to /opt/nfast/bin/racgui, or the appropriate installation directory.

    • On macOS, open the Launchpad and click the RemoteAdminClient icon.

      The Connect to Service (step 1 of 3) wizard page displays.

    Connect to Service (step 1 of 3)

  3. Enter the IP address or hostname of the required Remote Administration Service, or select the appropriate entry in the drop-down list that stores the last 10 connections that have been used. Examples of supported IP address types are:

    • IPv4 address: 194.3.4.106

    • IPv6 address: 2001:db8::2:1

    • Link-local IPv6 address with interface name: fe80::1%eth0

    • Link-local IPv6 address with interface number: fe80::1%2

      If the communication port has been changed from the default 9005, you can also enter the correct number here, separated by a colon. For example, Hostname:Port, 192.0.2.146:9006.

      Please note you need square brackets to distinguish between IPv6 and its port. For example:

    • IPv6 address: [2001:db8::2:1]:9006

    • Link-local IPv6 with interface name: [fe80::1%eth0]:9006

    • Link-local IPv6 with interface number: [fe80::1%2]:9006

      Square brackets are not required but are permitted for IPv4 addresses and hostnames.

  4. Click Connect to connect with the Remote Administration Service.

    An error message displays if a connection cannot be established with the IP address or hostname. You can retry or connect to a different Remote Administration Service.

    Depending upon your network environment, there may be a short delay in establishing a connection.

  5. On the Choose HSM (step 2 of 3) wizard page, select the appropriate HSM from the list, according to its ESN, and click Next.

    Choose HSM (step 2 of 3)
    HSMs that do not support Dynamic Slots because they do not have the appropriate firmware, or do not have any dynamic slots configured, cannot be selected. However, they still appear in the list.

  6. Ensure that an nShield Trusted Verification Device is connected to your local computer. The tool shows that no Smartcard have been inserted yet in nShield TVD:

    Select Card Reader (step 3 of 3)

    Select the Card Reader, insert the Smartcard in the nShield TVD slot, and click Next.

    You can connect the Trusted Verification Device after the nShield Remote Administration Client has been started. But you must connect it either before you reach the Select Card Reader (step 3 of 3) page, or while it is still being displayed, to be able to proceed.

  7. Check the displayed ESN against an independent record of the expected ESN.

    Card reader
    Do not just check the ESN against the one displayed on the last wizard page of the GUI.

    • If the ESN is correct, press OK on the nShield Trusted Verification Device to confirm. The screen of the device displays Accepted.

    • If there is a problem with the ESN, press C on the nShield Trusted Verification Device. The screen of the device displays Abort OK?. Press OK. The Card Status field on the Use Card Reader page displays Unknown card.

    • If you have selected the wrong HSM, return to the Choose HSM (step 2 of 3) page and select the correct one. Otherwise, proceed according to the security policies of your organization.

    If you remove and reinsert the card after you have confirmed the ESN of the HSM, the secure channel connection window re-displays. Select the HSM by its ESN again.

  8. The Use Card Reader dialog is displayed with information about the Remote Administration:

    Remote Administration Service

    <ip-address> of the Remote Administration server
    HSM ESN

    <hsm-esn>
    Slot Number

    Number of the dynamic slot used by the card
    Card Inserted

    Yes when the card is inserted in the TVD
    Card Serial Number

    <serial-number> of the Smartcard

The Remote Administration connection is now set up. All remote users will have to enter there passphrases as and when they are instructed to do so.

Do not exit or close the Use Card Reader dialog until you want to terminate the session.

Use the raccmd command-line utility to create an association with a dynamic slot

The raccmd command line utility is available on the machine on which the Remote Administration Client was installed. It enables you to:

  • List all available HSMs and select the appropriate one

  • List all locally available TVDs

  • Associate a TVD with an HSM, if a Dynamic Slot is available

Run the following command:

raccmd [-h] [--address ADDRESS] [--port PORT] [-v] [--version] {listhsms,listreaders,associate} ...

On macOS, you need to explicitly specify the path to the command-line utility:

/Applications/RemoteAdminClient.app/Contents/Resources/raccmd [-h] [--address ADDRESS] [--port PORT] [-v] [--version]
    {listhsms,listreaders,associate} ...

If the Remote Administration Client application has been installed for only the current user, then use ~/Applications/….

Example to connect to an HSM using raccmd

  1. At the command prompt, execute the listreaders and listhsms commands to check or confirm the information you will need for parameters of the raccmd command.

    c:\Program Files\nCipher\nfast\bin>raccmd.exe listreaders
1. name_of_TVD
2. name_of_another_card_reader_attached_to_machine
c:\Program Files\nCipher\nfast\bin>raccmd.exe --address Remote_Admin_Service_IP_Address listhsms
1. esn_number

    In this example, the TVD is listed as the first reader so the value of TVD_ID will be 1 for the raccmd command.

  2. Connect to the HSM:

    c:\Program Files\nCipher\nfast\bin>raccmd.exe --address Remote_Admin_Service_IP_Address associate -
interactive esn_number TVD_ID
Associated with slot 2
Reading...
Confirm HSM ESN on TVD

Example: load a Security World with quorum members presenting their cards via RACs

  1. All quorum members connect through a remote screen sharing tool.

  2. One quorum member connects to the Remote Administration Service, for example with ssh.

  3. All quorum members who need to present their cards remotely launch their Remote Administration Client and connect to the Remote Administration Service. See:

  4. The quorum member who is connected via ssh can confirm with the slotinfo command that dynamic slots have been configured so that other quorum members can present their cards remotely:

    Linux:

    #/opt/nfast/bin/slotinfo -m2

    Windows:

    C:\Program Files\nCipher\nfast\bin>slotinfo.exe -m2

    The following example is an output that shows a card present in the physical slot (Slot #0) of the HSM and a card presented via the Remote Administration client in a dynamic slot (here identified as Slot #2 with Flags ADa where D is dynamic).

    Module 2:
Slot    Type            Token       IC  Flags   Details
#0      Smartcard       present     1   A
#1      Software Tkn    -           0
#2      Smartcard       present     5   ADa
#3      Smartcard       -           0   AD

  5. The quorum member who is connected via ssh changes the HSM mode to Initialization remotely using the nopclearfail command:

    Linux:

    #/opt/nfast/bin/nopclearfail --initialization -m2
Module 2 command ClearUnitEx: OK

    Windows:

    C:\Program Files\nCipher\nfast\bin>nopclearfail.exe --initialization -m2 Module 2, command ClearUnitEx: OK

  6. The quorum member who is connected via ssh executes the new-world command.

    Linux:

    #/opt/nfast/bin/new-world -l -m2

    Windows:

    C:\Program Files\nCipher\nfast\bin>new-world.exe -l -m2

  7. The following message will be displayed:

    18:16:43 WARNING: Module #2: preemptively erasing module to see its slots!
Indoctrinating Module:
Module 2: 0 cards of 2 read
Module 2 slot 0: empty
Module 2 slot 2: empty
Module 2 slot 3: empty
Module 2 slot 2: Admin Card #3

  8. Each quorum member is now prompted to present their card. Members who are connected through RAC are prompted to use insert the Smartcard in the nShield TVD when the RAC Use Card Reader window appears.

  9. The quorum member connected via ssh can monitor the status of the remote cards in the messages:

    Module 2 slot 2:- passphrase supplied - reading card
Module 2: 1 card of 2 read
Module 2 slot 2: Admin Card #3: already read
Module 2 slot 2: empty
Module 2 slot 2: Admin Card #4
Module 2 slot 2:- passphrase supplied - reading card
Card reading complete.
security world loaded on 1 module; hknso = 78abcd62770e79eba69f556c4b596b9ed1d59e87

  10. When all cards were read, the HSM can be changed back to Operational mode with the nopclearfail command:

    Linux:

    #/opt/nfast/bin/nopclearfail --operational -m2 Module 2 command ClearUnitEx: OK

    Windows:

    C:\Program Files\nCipher\nfast\bin>nopclearfail.exe --operational -m2 Module 2, command ClearUnitEx: OK

  11. The mode of the HSM can be confirmed with the enquiry command on the ssh prompt:

    Linux:

    #/opt/nfast/bin/enquiry

    Windows:

    C:\Program Files\nCipher\nfast\bin>enquiry

    The Module#2 part of the configuration file is shown below:

    Module #2:
enquiry reply flags none
enquiry reply level Six
serial number 49D5-C944-F159
mode operational
.....

  12. The remote task has been completed. Remote quorum members can disconnect their Remote Administration Clients and the ssh connection can be closed.
