AW: Run dispatcher.d script when lte device is unplugged

["Chauchet, Martin" <martin chauchet fkie fraunhofer de>]

Hi,

thank you for your suggestion.
Unfortunately, starting OpenVPN is not the only thing we need to do when LTE comes up, so until now 
dispatcher.d seems to us what ist the most versatile solution to fit our needs. Anyways, I will give your 
solution a shot when the routers running NM will be back from the field test the are currently on. My last 
resort would be a cron job checking if lte0 is present, otherwise running the "stop" part of our 
configuration.

Best regards

this feature is built in into NetworkManager as far as I understand.
You should be able to setup a connection profile for LTE that is configured to automatically connect and as a 
"secondaries" setting you should be able to specify the UUID of a VPN profie that is automatically connected 
when the LTE profile is active.
https://developer.gnome.org/NetworkManager/unstable/nm-settings.html
is the reference I looked into for these settings.

Kind regards
