Functions

func AddHost

func AddHost(hostname, address string) error

AddHost adds a host to the map of known hosts An error is returned if the address has a wrong format or the hostname already exists The added host will not persist between program executions

func ChoosePathByMetric

func ChoosePathByMetric(pathAlgo int, local, remote *snet.Addr) *sciond.PathReplyEntry

ChoosePathByMetric chooses the best path based on the metric pathAlgo

func ChoosePathInteractive

func ChoosePathInteractive(local, remote *snet.Addr) *sciond.PathReplyEntry

ChoosePathInteractive presents the user a selection of paths to choose from

func GetDefaultDispatcher

func GetDefaultDispatcher() string

GetDefaultDispatcher returns the path to the default SCION dispatcher

func GetHostByName

func GetHostByName(hostname string) (libaddr.IA, libaddr.HostAddr, error)
