dsgwdashboard/util/NOTE.md

I have localized all of the configuration files in /usr/local/etc:

dashboard.ini - configuration for the dashboard (with some values also take from dstargateway.cfg)
dgwremotecontrol.cfg - configure remote control port and password
dgwtimeserver.cfg - this controls time announcements and other parameters
dstargateway.cfg - configure the gateway itself

The program systemctl is how your manage these services (as root using sudo) there are five functions which you will typically control

enable - turning on automatic startup when you reboot the system
status - tells you the current status of the service
start - start up a service that is currently inactive
stop - stop an active service
restart - issues a stop followed by a start
disable - turning off automatic startup when reboot

for example: ** sudo systemctl status dsgwdashboard
sudo systemctl enable dsgwdashboard
sudo systemctl start dsgwdashboard
sudo systemctl stop dsgwdashboard
sudo systemctl restart dsgwdashboard
sudo systemctl disable dsgwdashboard

sudo systemctl status dgwtimeserver
sudo systemctl enable dgwtimeserver
sudo systemctl start dgwtimeserver
sudo systemctl stop dgwtimeserver
sudo systemctl restart dgwtimeserver
sudo systemctl disable dgwtimeserver
**

and so forth.

To view the systemctl manual - type
man systemctl

Also spend some time with DStarGateway README (and the README.md in each subdirectory)
