Assuming that you downloaded the Linux tar file from Step #1 ...
It is recommended that you should install Ixia APIs in a central network location where everybody can access
them, but you can put it anywhere you want.
For this example, the Ixia API package ixos8.0_ixnetwork8.0_ixload8.0_hlt8.0.tar.gz
is copied to the directory /automation/ixia
CD to /automation/ixia directory.
Enter: chmod +x ixos8.0_ixnetwork8.0_ixload8.0_hlt8.0.tar.gz
(To make the file executable)
Enter: tar -zxvf ixos8.0_ixnetwork8.0_ixload8.0_hlt8.0.tar.gz
(To decompress the tar.gz file)
If you get an error: gzip: stdin: not in gzip format
Enter: tar -xvf ixos8.0_ixnetwork8.0_ixload8.0_hlt8.0.tar.gz
Your are done installing it.
Now your full path to the Ixia APIs is: /automation/ixia
Next step, configure the Linux environment variables in step 3.
