SOCKS Protocol Version 5 Library.

完整 TCP/UDP 和 IPv4/IPv6 支持. 目标: KISS, less is more, small API, code is like the original protocol.

Struct的概念 对标 原始协议里的概念

• Negotiation:
  • type NegotiationRequest struct
    • func NewNegotiationRequest(methods []byte), in client
    • func (r *NegotiationRequest) WriteTo(w io.Writer), client writes to server
    • func NewNegotiationRequestFrom(r io.Reader), server reads from client
  • type NegotiationReply struct
    • func NewNegotiationReply(method byte), in server
    • func (r *NegotiationReply) WriteTo(w io.Writer), server writes to client
    • func NewNegotiationReplyFrom(r io.Reader), client reads from server
• User and password negotiation:
  • type UserPassNegotiationRequest struct
    • func NewUserPassNegotiationRequest(username []byte, password []byte), in client
    • func (r *UserPassNegotiationRequest) WriteTo(w io.Writer), client writes to server
    • func NewUserPassNegotiationRequestFrom(r io.Reader), server reads from client
  • type UserPassNegotiationReply struct
    • func NewUserPassNegotiationReply(status byte), in server
    • func (r *UserPassNegotiationReply) WriteTo(w io.Writer), server writes to client
    • func NewUserPassNegotiationReplyFrom(r io.Reader), client reads from server
• Request:
  • type Request struct
    • func NewRequest(cmd byte, atyp byte, dstaddr []byte, dstport []byte), in client
    • func (r *Request) WriteTo(w io.Writer), client writes to server
    • func NewRequestFrom(r io.Reader), server reads from client
    • After server gets the client's *Request, processes...
• Reply:
  • type Reply struct
    • func NewReply(rep byte, atyp byte, bndaddr []byte, bndport []byte), in server
    • func (r *Reply) WriteTo(w io.Writer), server writes to client
    • func NewReplyFrom(r io.Reader), client reads from server
• Datagram:
  • type Datagram struct
    • func NewDatagram(atyp byte, dstaddr []byte, dstport []byte, data []byte)
    • func NewDatagramFromBytes(bb []byte)
    • func (d *Datagram) Bytes()

高级 API

这可以满足经典场景，特殊场景推荐你选择上面的小API来自定义。

Server: 支持UDP和TCP

• type Server struct
• type Handler interface
  • TCPHandle(*Server, *net.TCPConn, *Request) error
  • UDPHandle(*Server, *net.UDPAddr, *Datagram) error

举例:

server, _ := NewClassicServer(addr, ip, username, password, tcpTimeout, udpTimeout)
server.ListenAndServe(Handler)

Client: 支持TCP和UDP, 返回net.Conn

• type Client struct

举例:

client, _ := socks5.NewClient(server, username, password, tcpTimeout, udpTimeout)
conn, _ := client.Dial(network, addr)
