Functions ¶

func EncodeUDPPacket ¶

func EncodeUDPPacket(addr Addr, payload []byte) (packet []byte, err error)

func ServerHandshake ¶

func ServerHandshake(rw net.Conn) (addr Addr, command Command, err error)

ServerHandshake fast-tracks SOCKS initialization to get target address to connect on server side.

Types ¶

type Addr ¶

type Addr []byte

Addr represents a SOCKS address as defined in RFC 1928 section 5.

func ClientHandshake ¶

func ClientHandshake(rw io.ReadWriter, addr Addr, command Command) (Addr, error)

ClientHandshake fast-tracks SOCKS initialization to get target address to connect on client side.

func DecodeUDPPacket ¶

func DecodeUDPPacket(packet []byte) (addr Addr, payload []byte, err error)

DecodeUDPPacket split `packet` to addr payload, and this function is mutable with `packet`

func ParseAddr ¶

func ParseAddr(s string) Addr

ParseAddr parses the address in string s. Returns nil if failed.

func ParseAddrToSocksAddr ¶

func ParseAddrToSocksAddr(addr net.Addr) Addr

ParseAddrToSocksAddr parse a socks addr from net.addr This is a fast path of ParseAddr(addr.String())

func ReadAddr ¶

func ReadAddr(r io.Reader, b []byte) (Addr, error)

func SplitAddr ¶

func SplitAddr(b []byte) Addr

SplitAddr slices a SOCKS address from beginning of b. Returns nil if failed.

func (Addr) String ¶

func (a Addr) String() string

func (Addr) UDPAddr ¶

func (a Addr) UDPAddr() *net.UDPAddr

UDPAddr converts a socks5.Addr to *net.UDPAddr

type Command ¶

type Command = uint8

Command is request commands as defined in RFC 1928 section 4.

const (
	CmdConnect      Command = 1
	CmdBind         Command = 2
	CmdUDPAssociate Command = 3
)

SOCKS request commands as defined in RFC 1928 section 4.

type Error ¶

type Error byte

Error represents a SOCKS error

func (Error) Error ¶

func (err Error) Error() string

type SockListener ¶

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

func NewSocksProxy ¶

func NewSocksProxy(addr string, cb SocksCallback) (*SockListener, error)

func NewSocksProxyV2 ¶

func NewSocksProxyV2(addr string, cb SocksCallback, meter snellapi.TrafficMeter) (*SockListener, error)

func (*SockListener) Address ¶

func (l *SockListener) Address() string

func (*SockListener) Close ¶

func (l *SockListener) Close()

type SocksCallback ¶

type SocksCallback func(net.Conn, Addr)
