title: Python Sockets connect to FTP don't receive what I expect
body: <p>I am using python socket to connect to ftp.rediris.es and I don't receive the answer I expect after sending data. I explain this better with my code and answers:
  This is my code (test.py)</p>
  
  <pre><code>#!/usr/bin/env python
  
  import socket
  
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
  print "Socket Created"
  
  port = 21
  
  host = "ftp.rediris.es"
  
  ip = socket.gethostbyname(host)
  
  print ip
  
  print "ip of " +host+ " is " +ip
  
  s.connect ((ip, port))
  
  print "Socket Connected to "+host+" on ip "+ ip
  
  message = "HELP\r\n"
  
  s.sendall(message)
  
  reply = s.recv(65565)
  
  print reply
  </code></pre>
  
  <p>This is the answer when I run the code:</p>
  
  <pre><code> python test.py
  Socket Created
  130.206.1.5
  ip of ftp.rediris.es is 130.206.1.5
  Socket Connected to ftp.rediris.es on ip 130.206.1.5

  <p>I have tried this on the port 80 towards www.google.com, sending a GET / HTTP/1.1\r\n\r\n and seen the header perfectly. 
  What happens¿? Am I not sending the command right to the server¿? Thank you in advance</p>
