Functions

func CreateInterface

func CreateInterface(fd uintptr, ifName string, flags uint16) (createdIFName string, err error)

func TunIdRandom

func TunIdRandom(min, max int) int

Types

type IfReq

type IfReq struct {
	Name  [0x10]byte
	Flags uint16
	// contains filtered or unexported fields
}

type Interface

type Interface struct {
	io.ReadWriteCloser
	// contains filtered or unexported fields
}

Interface is a TUN/TAP interface.

func NewTAP

func NewTAP(ifName string) (ifce *Interface, err error)

Create a new TAP interface whose name is ifName. If ifName is empty, a default name (tap0, tap1, ... ) will be assigned. ifName should not exceed 16 bytes.

func NewTUN

func NewTUN(ifName string) (ifce *Interface, err error)

Create a new TUN interface whose name is ifName. If ifName is empty, a default name (tap0, tap1, ... ) will be assigned. ifName should not exceed 16 bytes.

func (*Interface) Close

func (inet *Interface) Close()

func (*Interface) GetFd

func (ifce *Interface) GetFd() int

func (*Interface) GetFdOS

func (ifce *Interface) GetFdOS() *os.File

func (*Interface) GetName

func (ifce *Interface) GetName() string

func (*Interface) IsTAP

func (ifce *Interface) IsTAP() bool

Returns true if ifce is a TAP interface, otherwise returns false;

func (*Interface) IsTUN

func (ifce *Interface) IsTUN() bool

Returns true if ifce is a TUN interface, otherwise returns false;

func (*Interface) Name

func (ifce *Interface) Name() string

Returns the interface name of ifce, e.g. tun0, tap1, etc..

func (*Interface) Open

func (tap_conn *Interface) Open(mtu uint, tapNum string, ifType string) (err error)

******************************************************************** ** Tap Device Open/Close/Read/Write ** ******************************************************************** NOTE: legacy tap device create method used with in tap driver only for now
