  1. Download the server installation package, nns3_server_package_*.tgz, into your server install directory.

  2. Optional. The product contains a SHA‑256 checksum that allows you to verify that the downloaded package is complete, unaltered, and safe to use. To take advantage of this checksum feature, download the checksum file nns3_server_package_*.tgz.sha256sum.txt. Place the .tgz file and the .txt file into the same directory and calculate the hash for the package using the following command:

    sha256sum -c nns3_server_package_*.tgz.sha256sum.txt

    If the result shows “OK” then the file is valid.

  3. Untar the package. For example, if your install directory is /opt:

    cd /opt 
tar -zxvf nns3_server_package_*.tgz

Untarring creates a directory called mfas where the files are unpacked. Using the previous example command, the directory /opt/mfas is created. /opt/mfas is referred to as <NNL_HOME>.

You can see the contents of the tarball in Server Tarball Contents.
