[arm-allstar] Announce when Internet is lost

[Dave Petrie]

Is there anyway to run a script that would ping let's say 8.8.8.8 and
announce
over the local repeater the hamvoip raspberry is controlling, that the
internet has been lost, disconnected.
I am helping a Ham friend that is a History teacher at a school and is
setting up, with the support and enthusiasm from school staff and
principal, a uhf repeater with a internet hotspot that recently stopped
working, i know there are lots of reason for the disconnect, we just want
to know when it happens.
Thanks
Dave
