Installing RPM Packages

Use this procedure to install the Napatech driver and tools from RPM packages.

About this task

The package installer dnf is used in this example. You can of course use your distributions preferred RPM package installer.

Unless you have GPG signed the RPM packages, you may have to use the --nogpgcheck option with dnf, for example:

$ sudo dnf --nogpgcheck install nt-driver-3gd-<version>.x86_64.rpm

Before you begin

Kernel headers for the running kernel are required if you do not install the nt-driver-3gd-modules package, or if you want to enable automatic rebuild of the kernel modules after kernel upgrades.

The tools profiling and monitoring depend on ncurses.

Steps

To install RPM packages and enable ntservice to start at boot time:

Procedure

If you have made the nt-driver-3gd-modules package optional, or if you want to enable automatic rebuild of the kernel modules after kernel upgrades, ensure that kernel headers for the running kernel are installed before installing the nt-driver-3gd package:
```
$ sudo dnf install kernel-devel-$(uname -r) gcc make
```

Install the nt-driver-3gd-modules package, unless you have edited the spec file to make the nt-driver-3gd-modules package optional:

$ sudo dnf install nt-driver-3gd-modules-<version>.x86_64.rpm

where:

version is the version identifier of the package.

Note: Upgrading from an older package to a newer package may generate an error message as follows:

$ sudo dnf install nt-driver-3gd-modules-3.29.2.91-5.14.0_407.el9.x86_64.rpm

  file /opt/napatech3/config from install of nt-driver-3gd-modules-3.29.2.91-5.14.0_407.el9.x86_64 conflicts with file from package nt-driver-3gd-modules-3.28.12.10-5.14.0_407.el9.x86_64

The old packages must be removed first with the following command:

dnf remove nt-driver-3gd-modules nt-driver-3gd nt-tools-3gd

Install the nt-driver-3gd package:
```
$ sudo dnf install nt-driver-3gd-<version>.x86_64.rpm
```
where:
- version is the version identifier of the package.

Optionally, install devel, examples, doc and tools packages:

$ sudo dnf install nt-driver-3gd-devel-<version>.rpm
$ sudo dnf install nt-driver-3gd-examples-<version>.rpm
$ sudo dnf install nt-driver-3gd-docs-<version>.rpm
$ sudo dnf install nt-tools-3gd-<version>.rpm
$ sudo dnf install nt-tools-3gd-docs-<version>.rpm

where:

version is the version identifier of the package.

Start the driver with the following commands.
```
$ sudo modprobe nt3gd
$ sudo modprobe nt3gd_netdev
```
Note: This step is not required on every boot as the driver is automatically loaded during boot.

Enable ntservice to start at boot time:

$ sudo systemctl start ntservice
$ sudo systemctl enable ntservice
