Still doesn't work.

import socket

#create an INET, STREAMing socket
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#bind the socket to a public host,
# and a well-known port
serversocket.bind((socket.gethostname(), 8888))
#become a server socket
serversocket.listen(5)

When I try it on windows I get this:

Traceback (most recent call last):
   File 
"C:\Python22\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", 
line 301, in RunScript
     exec codeObject in __main__.__dict__
   File "C:\Documents and Settings\patrick\Desktop\p2pdev\simple.py", 
line 1, in ?
     import socket
   File "socket.py", line 72, in ?
     errorTab[10004] = "The operation was interrupted."
   File "C:\Python22\lib\SocketServer.py", line 273, in ?
     class TCPServer(BaseServer):
   File "C:\Python22\lib\SocketServer.py", line 316, in TCPServer
     address_family = socket.AF_INET
AttributeError: 'module' object has no attribute 'AF_INET'

On Linux I get this:
patrick@enterprise /opt/data $ python simple.py
patrick@enterprise /opt/data $

but

patrick@enterprise /opt/data $ nmap -p 8888 localhost

Starting nmap 3.27 ( www.insecure.org/nmap/ ) at 2003-06-23 23:10 BST
The 1 scanned port on localhost (127.0.0.1) is: closed

Nmap run completed -- 1 IP address (1 host up) scanned in 0.318 seconds
patrick@enterprise /opt/data $


So something is still failing badly here.

Could you try this code on your machine please?  I need a sanity check!
