Functions

func DialMarkedTCP

func DialMarkedTCP(network string, laddr, raddr *net.TCPAddr, mark int) (net.Conn, error)

DialMarkedTCP creates a new TCP connection and marks it with the provided mark.

func GetOriginalDestination

func GetOriginalDestination(conn net.Conn) (net.Conn, net.IP, int, error)

GetOriginalDestination -- Func to get original destination a connection

func MarkConnection

func MarkConnection(conn net.Conn, mark int) error

Types

type ProxiedConnection

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

ProxiedConnection is a proxied connection where we can recover the original destination.

func (*ProxiedConnection) Close

func (p *ProxiedConnection) Close() error

Close closes the connection.

func (*ProxiedConnection) GetOriginalDestination

func (p *ProxiedConnection) GetOriginalDestination() (net.IP, int)

GetOriginalDestination sets the original destination of the connection.

func (*ProxiedConnection) GetTCPConnection

func (p *ProxiedConnection) GetTCPConnection() *net.TCPConn

GetTCPConnection returns the TCP connection object.

func (*ProxiedConnection) LocalAddr

func (p *ProxiedConnection) LocalAddr() net.Addr

LocalAddr implements the corresponding method of net.Conn, but returns the original address.

func (*ProxiedConnection) Read

func (p *ProxiedConnection) Read(b []byte) (n int, err error)

Read reads data from the connection.

func (*ProxiedConnection) RemoteAddr

func (p *ProxiedConnection) RemoteAddr() net.Addr

RemoteAddr returns the remote address

func (*ProxiedConnection) SetDeadline

func (p *ProxiedConnection) SetDeadline(t time.Time) error

SetDeadline passes the read deadline to the original TCP connection.

func (*ProxiedConnection) SetReadDeadline

func (p *ProxiedConnection) SetReadDeadline(t time.Time) error

SetReadDeadline implements the call by passing it to the original connection.

func (*ProxiedConnection) SetWriteDeadline

func (p *ProxiedConnection) SetWriteDeadline(t time.Time) error

SetWriteDeadline implements the call by passing it to the original connection.

func (*ProxiedConnection) Write

func (p *ProxiedConnection) Write(b []byte) (n int, err error)

Write writes data to the connection.

type ProxiedListener

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

ProxiedListener is a proxied listener that uses proxied connections.
