SMS Server Tools 3 or SMS3 is a great piece of SMS Gateway open source software that allows you to send and receive short SMS messages through any number of GSM modem types or mobile phones.
It installs itself as a service on an Ubuntu Linux machine and after some setup configuration the software is good to go, verified by the fact that a service –status-all terminal call should result in showing up SMS3 somewhere in the resulting running services list.
To stop the SMS3 service, you simply need to run this line from a terminal command:
sudo service sms3 stop
To start it up again, use:
sudo service sms3 start
To restart the service completely:
sudo service sms3 restart
(You’ll notice the use of sudo to elevate your user privileges to ensure that you can interact with the possible locked service files.)
