用Python写socks5服务器端

用Python写socks5服务器端
参考自RFC1928: http://xiaoxia.org/?p=2672
直接运行这个程序就给本机建立了一个socks5的代理服务器。
代码如下：

1. import
2.   
3. class ThreadingTCPServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer): pass
4. class
5. def handle_tcp(self, sock, remote):  
6.         fdset = [sock, remote]  
7. while True:  
8.             r, w, e = select.select(fdset, [], [])  
9. if sock in
10. if remote.send(sock.recv(4096)) <= 0: break
11. if remote in
12. if sock.send(remote.recv(4096)) <= 0: break
13. def handle(self):  
14. try:  
15. print 'socks connection from ', self.client_address  
16. self.connection  
17. # 1. Version
18. 262)  
19. "\x05\x00");  
20. # 2. Request
21. self.rfile.read(4)  
22. 1])  
23. 3])  
24. if addrtype == 1:       # IPv4
25. self.rfile.read(4))  
26. elif addrtype == 3:     # Domain name
27. self.rfile.read(ord(sock.recv(1)[0]))  
28. '>H', self.rfile.read(2))  
29. "\x05\x00\x00\x01"
30. try:  
31. if mode == 1:  # 1. Tcp connect
32.                     remote = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
33. 0]))  
34. print 'Tcp connect to', addr, port[0]  
35. else:  
36. "\x05\x07\x00\x01" # Command not supported
37.                 local = remote.getsockname()  
38. 0]) + struct.pack(">H", local[1])  
39. except
40. # Connection refused
41. '\x05\x05\x00\x01\x00\x00\x00\x00\x00\x00'
42.             sock.send(reply)  
43. # 3. Transfering
44. if reply[1] == '\x00':  # Success
45. if mode == 1:    # 1. Tcp connect
46. self.handle_tcp(sock, remote)  
47. except
48. print 'socket error'
49. def
50. '', 1080), Socks5Server)  
51.     server.serve_forever()  
52. if __name__ == '__main__':
