Functions

func DialTCP

func DialTCP(laddr, raddr *net.TCPAddr, isnonblocking bool) (*net.TCPConn, error)

DialTCP will open a TCP connection to the specified destination with the specified local address.

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

Types

type Conn

type Conn struct {
	*net.TCPConn
}

Conn describes a connection accepted by the TProxy listener.

It is simply a TCP connection with the ability to dial a connection to the original destination while assuming the IP address of the client

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) AcceptTProxy

func (listener *Listener) AcceptTProxy() (*Conn, error)

AcceptTProxy will accept a TCP connection and wrap it to a TProxy connection to provide TProxy functionality

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
