#from socket import *

import sys

HOST = ''       #any address
PORT = socket.htons(9222)        #same port address as client

class Sock:
     def __init__ (self,parent):
          try:
               self.s = socket(AF_INET,SOCK_STREAM)
          except socket.error:
                print 'socket not created'
          try:
               self.s.bind((HOST,PORT))
          except self.error:
               print 'error in bind'
          try:
               self.s.listen(5)
          except self.error:
               print 'error in listen'
          conn, addr = self.s.accept()
             #  print 'Connected by',`addr`
          while 1:
               data = conn.recv(1024)
               if not data: break
               conn.send(data)
          conn.close()
