Thread-topic: How to detect internet becoming available

Hello,

we have an Linux ARM board that can be connected to the internet

using a wired connection.

Chrony is started at boot time.

After a power failure it can happen that our board starts up BEFORE

internet becomes available, for example because the router it is

connected to has a higher startup-and-sync time than our board.

How can I inform chrony that internet is available?

I know I can use the command "chronyc online", but how can I trigger

that without using network manager?

Uwe Fechner
