IGEL Third-party Endpoint Partners: Ensuring Image Integrity with a Checksum
Overview
To ensure the integrity of your master image, it is recommended to create checksums and compare them between the original image and the images derived from it. This article describes how to create checksums for IGEL OS images that have been created using the IGEL OS Creator (OSC).
Requirements
IGEL OS Creator (OSC) with IGEL OS 11.05.120 or higher
Instructions
For IGEL OS images that have been created with IGEL OSC Creator (OSC), partition 4 of the main device must be checked with the checksum method.
In the following example, the main device is /dev/sda:
Open a terminal on the device that contains the image. For more information, see Terminals.
In the terminal, enter sha512sum /dev/sda4 The result should look like this: 7d5a25fac1756ef81ac78398d49db197904f60a0cf6594eac92071a5f6a8d6d4562fd3c8dc127cf22f89f6894000ca94918703c7143bfb11f1dd2ec052eaa52d /dev/sda4
Repeat this process for all IGEL OS image copies you want to check and compare their checksums. If the checksums are identical, the images can be deployed.
