Types

type Credential

type Credential struct {
	Username string
	Password string
}

type SocksAuthenticationPacket

type SocksAuthenticationPacket struct {
	Packet    []byte
	Version   byte
	NUserName byte
	UserName  []byte
	NPassword byte
	Password  []byte
}

type SocksBasicPacket

type SocksBasicPacket struct {
	Raw      []byte
	Version  byte
	NMethods byte
	Methods  []byte
}

*

   The localConn connects to the dstServer, and sends a ver
   identifier/method selection message:
	          +----+----------+----------+
	          |VER | NMETHODS | METHODS  |
	          +----+----------+----------+
	          | 1  |    1     | 1 to 255 |
	          +----+----------+----------+
   The VER field is set to X'05' for this ver of the protocol.  The
   NMETHODS field contains the number of method identifier octets that
   appear in the METHODS field.

第一个字段VER代表Socks的版本，Socks5默认为0x05，其固定长度为1个字节

type SocksConfig

type SocksConfig struct {

type SocksDetailPacket

type SocksDetailPacket struct {
	Packet   []byte
	Version  byte
	CMD      byte
	RSV      byte
	ATYP     byte
	DST_ADDR []byte
	DST_PORT []byte
}

*

+----+-----+-------+------+----------+----------+
|VER | CMD |  RSV  | ATYP | DST.ADDR | DST.PORT |
+----+-----+-------+------+----------+----------+
| 1  |  1  | X'00' |  1   | Variable |    2     |
+----+-----+-------+------+----------+----------+
