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 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 NewTproxy

func NewTproxy(opt *cl.Opts[*cl.Protocol_Tproxy]) (netapi.Server, error)

func ReadFromUDP

func ReadFromUDP(conn *net.UDPConn, b []byte) (n int, srcAddr *net.UDPAddr, dstAddr *net.UDPAddr, err 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 Tproxy

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

func (*Tproxy) Close

func (t *Tproxy) Close() error
