Types

type IntraListener

type IntraListener interface {
	intra.UDPListener
	intra.TCPListener
}

type OutlineTunnel

type OutlineTunnel interface {
	Tunnel
	// SetUDPEnabled indicates whether the tunnel and/or the network support UDP traffic.
	SetUDPEnabled(isUDPEnabled bool)
}

Tunnel represents a tunnel from a TUN device to a server.

func NewTunnel

func NewTunnel(host string, port uint16, isUDPEnabled bool, tunWriter io.WriteCloser) (OutlineTunnel, error)

NewTunnel connects a tunnel to a SOCKS5 server and returns a `Tunnel` object.

`host` is the IP or domain of the SOCKS server. `port` is the port of the SOCKS server. `isUDPEnabled` indicates if the SOCKS server and the network support proxying UDP traffic. `tunWriter` is used to output packets back to the TUN device.

type Tunnel

type Tunnel interface {
	// IsConnected indicates whether the tunnel is in a connected state.
	IsConnected() bool
	// Disconnect disconnects the tunnel.
	Disconnect()
	// Write writes input data to the TUN interface.
	Write(data []byte) (int, error)
}

Tunnel represents a session on a TUN device.

func NewIntraTunnel

func NewIntraTunnel(fakedns, udpdns, tcpdns string, tunWriter io.WriteCloser, listener IntraListener) (Tunnel, error)

NewIntraTunnel creates a connected Intra session.

`fakedns` is the DNS server (IP and port) that will be used by apps on the TUN device.

This will normally be a reserved or remote IP address, port 53.

`udpdns` and `tcpdns` are the actual location of the DNS server in use.

These will normally be localhost with a high-numbered port.
