This will work if you uncomment the lines in install/setup.sh that refer to creating and installing the service and then run setup. The below still works, but is not great for troubleshooting. It is suggested to use the startup commands @ here to run SFN.

SafeNetworking runs as a system service in Ubuntu. You have the same commands for SafeNetworking as you would for any other service - i.e. systemctl and service.

To view if SafeNetworking is running:

sudo service sfn status

To stop SafeNetworking:

sudo service sfn stop

To start SafeNetworking (this takes a minute):

sudo service sfn start

To restart SafeNetworking (this takes a minute)"

sudo service sfn restart

If, for some reason, SafeNetworking does not start automatically, you can use the 'journalctl' to view the logfile for system errors when trying to start SafeNetworking.
