What is a Host ID?

Thank you for wanting to evaluate or buy a Cradle Product.

As part of the order or evaluation process, you will need to enter the Host ID of the specific computer which you are going to install Cradle onto. The Host ID will be used to create part of the security code which ties your Cradle installation to that specific computer.

To find your Host ID for Windows installations:

  1. Click on the Start menu at the bottom left of your windows system.
  2. Click on Run.
  3. In the Run dialog type: cmd
  4. Navigate to the boot disk (normally C:\ by typing C: )
  5. In the Command Window type: vol
  6. The Host ID is the Volume Serial Number and it fits the pattern XXXX-XXXX
  7. We require this just as the 8 digits, so for the above the Host ID we would require would be: 3C02B81F

For Linux installations:

  1. We need the Ethernet address of the /dev/eth0 interface, which is the output from an ifconfig -a command
  2. This will return something like:
    > ifconfig -a

    eth0 Link encap:Ethernet HWaddr 00:0c:21:ec:bc:ed
    inet addr:10.0.0.37 Bcast:10.0.255.255 Mask:255.255.0.0
    inet6 addr: fe80::20c:29ff:feed:beff/64 Scope:Link
    UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
    RX packets:9665655 errors:0 dropped:0 overruns:0 frame:0
    TX packets:9829389 errors:0 dropped:0 overruns:0 carrier:0
    collisions:0 txqueuelen:1000
    RX bytes:2335543468 (2.3 GB) TX bytes:1123879531 (1.1 GB)


  3. The last 8 digits (The bit we have coloured green) is what we require, but without the colons.
  4. So for the example above, the Ethernet Address we would require to create a security code would be 21ecbced
  5. So when requesting a Security Code, you would enter 21ecbced in the Host ID box on the form.

For Solaris installations:

  1. We need the output from the command: hostid (It is an 8 character hex number).
