US Patent 10257280 Systems and methods for remote management of appliances

The present disclosure describes systems and methods for remote management of appliances. The appliance may be configured to periodically check in a predetermined online location for the presence of a trigger file identifying one or more appliances directed to contact a management server for maintenance. If the file is present at the predetermined location and the file includes the identifier of the appliance, the appliance may initiate a connection to the management server. If the file is not found, then the appliance may reset a call timer and attempt to retrieve the file at a later time. To avoid having to configure addresses on the appliance, link local IPv6 addresses may be configured for use over a virtual private network, allowing administration, regardless of the network configuration or local IP address of the appliance.
