Of course, this is the writing client.

Now I have a small problem with the reading client.

This code works so far:

  sfo = sock.makefile('r')
  taro = tarfile.open(fileobj=sfo,mode='r|')

But it does not writes anything to the terminal to inform the user.

When I use:

  for member in taro.getmembers():
      print('extracting "%s"' % member.name)

I get the error:

  File "/usr/lib/python2.7/tarfile.py", line 556, in seek
    raise StreamError("seeking backwards is not allowed")

Of course, a stream is not seekable.

Any ideas?
