I have:

  sock = socket.create_connection((server,port))
  bs = kB64
  taro = tarfile.open(fileobj=sock.makefile('w',kB64),mode='w')
  
  
        
Traceback (most recent call last):
  (...)
  File "./fexit.py", line 1838, in sex_send
    taro = tarfile.open(fileobj=sock.makefile('w',kB64),mode='w')
  File "/usr/lib/python2.7/tarfile.py", line 1695, in open
    return cls.taropen(name, mode, fileobj, **kwargs)
  File "/usr/lib/python2.7/tarfile.py", line 1705, in taropen
    return cls(name, mode, fileobj, **kwargs)
  File "/usr/lib/python2.7/tarfile.py", line 1566, in __init__
    self.offset = self.fileobj.tell()
AttributeError: '_fileobject' object has no attribute 'tell'
