Installing Napatech Link™ Capture Software

Install Napatech Link™ Capture Software using the package installer script included in the product release package.

Before you begin

You need to install the following:

Linux kernel development headers, GCC version 4.0 or later, glibc, and make (you should have already installed these in Installing the OPAE Framework)
ncurses version 5.0 or later (only applies to the monitoring, profiling and setup_wizard tools):
```
sudo yum install ncurses
```

Procedure

Go to the Napatech site: https://www.napatech.com/products/link-capture-software-for-intel/.
From the toolbar, click Download Software.

Scroll down to Link™ Capture Software for Intel® Programmable Acceleration Card with Intel Arria® 10 GX FPGA and download either the Windows or Linux product package.
Unpack the product package:
```
tar xzf ntanl_package_3gd_intel_pac-x.y.z-linux.tar.gz
cd ntanl_package_3gd_intel_pac-x.y.z-linux
```
The unpacked product directory contains:
- Product package release notes.
- A readme file, describing the product package content.
- A package install shell script, a product package install script.
- A documentation subdirectory.
- A subdirectory for each product package component, containing release notes and an installer file for the component.
Install the Napatech driver and tools:
Note: You need root privileges to install and compile the Linux driver and the tools.
```
sudo package_install_3gd-x.y.z.sh
```
The product package installer script is located in the root directory. This installs the driver software, the tools, documentation, FPGA images, and optionally a version of libpcap.

If the product package installer script detects that a version of the driver software is already installed, you can update the existing installation, delete the existing installation before commencing, or quit the installation script.

You can install a version of libpcap with Napatech extensions. For more information about libpcap with Napatech extensions, see DN-0428.
The /opt/napatech3/ directory, including subfolders, is created. The driver is installed and compiled to match the target Linux kernel version.

Note: Napatech Link™ Capture Software with Intel® PAC A10 GX does not show up as a standard network interface when you run network tools such as ifconfig or ip. See Overview for more information.
