func (WindowsNetManager) ComputeNetworkConfig

func (WindowsNetManager) GetConfiguredNetworkInterfaces

func (net WindowsNetManager) GetConfiguredNetworkInterfaces() ([]string, error)

GetConfiguredNetworkInterfaces returns all of the network interfaces if a previous call to SetupNetworking succeeded as indicated by the presence of a file ("configured_interfaces.txt").

A file is used because there is no good way to determine if network interfaces are configured on Windows and SetupNetworking may be called during bootstrap so it is possible the agent will have restarted since it the last call.

We return all of the network interfaces as we configure DNS for all of the network interfaces. Apart from DNS, the returned network interfaces may not have been configured.

func (net WindowsNetManager) SetupIPv6(_ boshsettings.IPv6, _ <-chan struct{}) error

func (WindowsNetManager) SetupNetworking
