Step 3: Download the Data Defender Files - AWS Ground Station

Step 3: Download the Data Defender Files

  1. Create a new directory to store the Data Defender files and download them from Amazon S3 by running the following commands.

    mkdir "ddx_2.6.2-104" aws --region us-west-2 s3 cp --recursive "s3://groundstation-customer-assets-us-west-2/ddx/2.6.2-104" "ddx_2.6.2-104"

    An example output is provided below.

  2. Verify that the hashcode from the downloaded ISO matches the expected hashcode by running the following commands.

    cd "ddx_2.6.2-104" md5sum "ddx-2.6.2-104.iso" > "downloaded-md5-ddx-2.6.2-104.iso.txt" diff "md5-ddx-2.6.2-104.iso.txt" "downloaded-md5-ddx-2.6.2-104.iso.txt"

    The diff command will only produce output to the console if there is a mismatch in the hashcode. There will be no output to the console from the diff command if the ISO’s hashcode matches the expected hashcode. An example output is provided below.
