Functions ¶

func DialUDP ¶

func DialUDP(network string, laddr *net.UDPAddr, raddr *net.UDPAddr) (*net.UDPConn, error)

DialUDP connects to the remote address raddr on the network net, which must be "udp", "udp4", or "udp6". If laddr is not nil, it is used as the local address for the connection.

func ListenTCP ¶

func ListenTCP(network string, laddr *net.TCPAddr) (net.Listener, error)

ListenTCP will construct a new TCP listener socket with the Linux IP_TRANSPARENT option set on the underlying socket

func ListenUDP ¶

func ListenUDP(network string, laddr *net.UDPAddr) (*net.UDPConn, error)

ListenUDP will construct a new UDP listener socket with the Linux IP_TRANSPARENT option set on the underlying socket

func ReadFromUDP ¶

func ReadFromUDP(conn *net.UDPConn, b []byte) (int, *net.UDPAddr, *net.UDPAddr, error)

ReadFromUDP reads a UDP packet from c, copying the payload into b. It returns the number of bytes copied into b and the return address that was on the packet.

Out-of-band data is also read in so that the original destination address can be identified and parsed.

Types ¶

type Config ¶

type Config struct {
	LocalHost  string `json:"local_addr" yaml:"local-addr"`
	LocalPort  int    `json:"local_port" yaml:"local-port"`
	UDPTimeout int    `json:"udp_timeout" yaml:"udp-timeout"`
}

type Conn ¶

type Conn struct {
	net.Conn
	// contains filtered or unexported fields
}

func (*Conn) Epoch ¶

func (c *Conn) Epoch() time.Time

func (*Conn) Metadata ¶

func (c *Conn) Metadata() *tunnel.Metadata

func (*Conn) Name ¶

func (c *Conn) Name() string

func (*Conn) Recv ¶

func (c *Conn) Recv() uint64

func (*Conn) Sent ¶

func (c *Conn) Sent() uint64

func (*Conn) Tunnels ¶

func (c *Conn) Tunnels() *tunnel.Tunnels

func (*Conn) User ¶

func (c *Conn) User() statistic.User

type Listener ¶

type Listener struct {
	// contains filtered or unexported fields
}

Listener describes a TCP Listener with the Linux IP_TRANSPARENT option defined on the listening socket

func (*Listener) Accept ¶

func (listener *Listener) Accept() (net.Conn, error)

Accept waits for and returns the next connection to the listener.

This command wraps the AcceptTProxy method of the Listener

func (*Listener) Addr ¶

func (listener *Listener) Addr() net.Addr

Addr returns the network address the listener is accepting connections from

func (*Listener) Close ¶

func (listener *Listener) Close() error

Close will close the listener from accepting any more connections. Any blocked connections will unblock and close

type PacketConn ¶

type PacketConn struct {
	net.PacketConn
	// contains filtered or unexported fields
}

func (*PacketConn) Close ¶

func (c *PacketConn) Close() error

func (*PacketConn) Epoch ¶

func (*PacketConn) Recv ¶

func (c *PacketConn) Recv() uint64

func (*PacketConn) Sent ¶

func (c *PacketConn) Sent() uint64

func (*PacketConn) Tunnels ¶
