Configuring parameters

The time-stamping and time synchronization parameters are configured in the ntservice.ini file. The ntservice.ini file is located under the installation directory by default. The default directory on Linux is /opt/napatech3/config. The default directory on Windows is C:\Program Files\Napatech3\config or C:\Program Files (x86)\Napatech3\config. The following ntservice.ini code is a typical system configuration for OS time synchronization.

TimeSyncReferencePriority=OsTime

Restart the ntservice daemon or NTService

After changing the configuration in the ntservice.ini file, please restart the ntservice daemon or NTService. The example below shows stopping the ntservice daemon and starting it again on Linux. Please refer to Load the Driver and Start the ntservice Daemon on Linux as well as DN-0379 for details on how to stop and how to start ntservice daemon.

# /opt/napatech3/bin/ntstop.sh
Stopping NTService (this may take a while)
NTService stopped                                           [Done]
# /opt/napatech3/bin/ntstart.sh
Starting NTService (this may take a while)                  [Done]

Stop and restart NTService in service mode

The following command example shows how to stop and how to restart NTService in service mode on Windows. Please refer to Check the Driver and Start the NTService on Windows as well as DN-0394 or DN-1067 for details on how to stop and how to start NTService.

C:\Program Files\Napatech3\bin>NTService.exe -k
Stopping the service: "Napatech Software Suite 64 bit".

C:\Program Files\Napatech3\bin>NTService.exe -s
Starting the service: "Napatech Software Suite 64 bit"
"Napatech Software Suite 64 bit" is started
