# The purpose of this script is to check if VPN connection is active
|
|
# This script will be called (via a service) in 2 situations:
|
|
# On a regular basis when transmission is running
|
|
# This will be achieved with a timer started and stopped with transmission service
|
|
# On transmission starting
|
|
# When the script exits with failure, associated service should try to start transmission service
|
|
# Thus this script will be executed again
|
|
# We can enter an infinite loop, but this will effectively prevent transmission from connecting
|
|
# If both services are stopped, this script will never be run by error
|
