Variables

var NativeEndian binary.ByteOrder

NativeEndian is the ByteOrder of the current system.

Functions

func DisableForwardingForInterface

func DisableForwardingForInterface(iface *net.Interface) error

DisableForwardingForInterface disables forwarding for given interface. The process must run with elevated rights. Otherwise the function will fail with an "Access Denied" error.

func EnableForwardingForInterface

func EnableForwardingForInterface(iface *net.Interface) error

EnableForwardingForInterface enables forwarding for given interface. The process must run with elevated rights. Otherwise the function will fail with an "Access Denied" error.

func GetDefaultGatewayInterface

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

GetDefaultGatewayInterface returns the first network interface found with a default gateway set

func GetInterfaceByIP

func GetInterfaceByIP(search net.IP) (*net.Interface, error)

GetInterfaceByIP tries to get the network interface with the given ip address

func GetInterfaceIP4Addr

func GetInterfaceIP4Addr(iface *net.Interface) (net.IP, error)

GetInterfaceIP4Addr returns the IPv4 address for the given network interface

func IsForwardingEnabledForInterface

func IsForwardingEnabledForInterface(iface *net.Interface) (bool, error)

func NativelyLittle

func NativelyLittle() bool
