Starting ntservice at boot time

ntservice can be managed by systemd including starting ntservice on boot.

Running ntservice as a service as a root user

After the Napatech Link-Capture™ Software installation is complete, it is possible to enable ntservice as a service via systemd.

Create a file named ntservice.service and include the following properties:

[Unit]
Description=Napatech 3GD Service

[Service]
Type=forking
GuessMainPID=yes
User=root
Group=root
RuntimeDirectory=root
RuntimeDirectoryMode=775
RuntimeDirectoryPreserve=yes
ExecStart=/opt/napatech3/bin/ntstart.sh --managed
ExecStop=/opt/napatech3/bin/ntstop.sh --managed
TimeoutStartSec=0
TimeoutStopSec=0
Restart=on-abnormal
SuccessExitStatus=0 1
RestartPreventExitStatus=1

[Install]
WantedBy=multi-user.target

Place the file in the following directory.

/etc/systemd/system/

Run these commands.

systemctl daemon-reload
systemctl enable ntservice

The first command reloads the systemd configuration, and the second command enables ntservice as a service. For the first time, you can start or stop the service as follows:

systemctl start ntservice
systemctl stop ntservice

ntservice is enabled by default in the subsequent reboots.

Running ntservice as a service as a non-root user

Add EPEL as described here: https://docs.fedoraproject.org/en-US/epel/.

Install DKMS. For example:

dnf update
dnf install dkms

Install Napatech Link-Capture™ Software. See Compile and Install the Linux Driver and the Tools.

Build and install the driver using DKMS. For example:

export PACKAGE_VERSION=$(cat /opt/napatech3/driver/src/driver/VERSION)
cp -r /opt/napatech3/driver/src /usr/src/ntdrv-${PACKAGE_VERSION}
cp /opt/napatech3/examples/integration/dkms/dkms.conf /usr/src/ntdrv-${PACKAGE_VERSION}/
dkms build ntdrv/${PACKAGE_VERSION}
dkms install ntdrv/${PACKAGE_VERSION}
cp /opt/napatech3/exampels/integration/modules-load.d/nt3gd.conf /etc/modules-load.d/nt3gd.conf

Copy files for systemd as follows.

cp -r /opt/napatech3/examples/integration/sysusers.d /etc
cp -r /opt/napatech3/examples/integration/systemd/ntservice.service /etc/systemd/system/

Run these commands.

systemctl daemon-reload
systemctl enable ntservice

The first command reloads the systemd configuration, and the second command enables ntservice as a service. For the first time, you can start or stop the service as follows:

systemctl start ntservice
systemctl stop ntservice

ntservice is enabled by default in the subsequent reboots. For the systemd setup files and instructions, see systemd integration in DN-0449.

Note: This procedure needs to be repeated after upgrading the kernel to a newer version.
