Receive packet using socket

[tspiegelman at amplify.com]

Hey all,

I am trying to use socket to send / receive a packet (want to recreate some functionality of hping3 and port it to windows and mac as a tcp ping).  I am having some problems with the recv functionality of socket.  Below is the script I am using.  I get an ack from the server (used wireshark to ensure it was working) when I run this, but the script doesn't see the ack for some reason and the script exits with this error or a timeout:

  Traceback (most recent call last):
  File "./tcpgcmtesttristedit.py", line 21, in <module>
    s.recv(1024)	
socket.error: [Errno 104] Connection reset by peer

Here is the script:

import socket
import time

numberofpackets = int(raw_input("How many packets should be sent?\n> "))
hostname = 'mtalk.google.com'
port = 5228

for i in range(numberofpackets):
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.settimeout(4)
        s.connect((hostname, port))
        s.send('data')
        start_time = time.time()
        s.recv(24)
        print time.time() - start_time
        s.close()


Any help would be much appreciated.  Thanks, Tom.
