func DefaultRouteInterface

func DefaultRouteInterface() (*net.Interface, error)

DefaultRouteInterface is like DefaultRoute but only returns the interface name.

Types

type DefaultRouteDetails

type DefaultRouteDetails struct {
	// InterfaceName is the interface name. It must always be populated.
	// It's like "eth0" (Linux), "Ethernet 2" (Windows), "en0" (macOS).
	InterfaceName string

	// InterfaceDesc is populated on Windows at least. It's a
	// longer description, like "Red Hat VirtIO Ethernet Adapter".
	InterfaceDesc string

	// InterfaceIndex is like net.Interface.Index.
	// Zero means not populated.
	InterfaceIndex int
}

DefaultRouteDetails are the details about a default route returned by DefaultRoute.
