|

==================
|
||||
|
||||
This package adds a script to change the SSID when there is no connection to any
|
||||
gateway. This Offline-SSID can be generated from the node's hostname with the
|
||||
first and last part of the node name or the MAC address allowing observers to
|
||||
recognize which node does not have a connection to a gateway. This script is
|
||||
called once every minute by ``micron.d`` and check gateway-connectivity. It will
|
||||
called once every minute by ``micrond`` and check gateway-connectivity. It will
|
||||
change the SSID to the Offline-SSID after the node lost gateway connectivity for
|
||||
several consecutive checks. As soon as the gateway-connectivity is back it
|
||||
toggles back to the original SSID.
