XP-> linux socket (XMLRPC) connection errors

[getafixx]

Hello everyone,

We have a linux server (Fedora core 7, default install, firewall turned off) and a bunch of windows XP machines on network/domain.

All machines are visible and I can get to both windows and linux by various methods.

We are trying to resolve a problem of not being able to connect to the linux box from the xp machines using python XMLRPC. (This is the module used in the software I am trying to set up)

Python is at 2.4 and 2.5 on windows machines and 2.5 on Linux.

Using this sample code from
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/81549/index_txt

# Server code
 
import SimpleXMLRPCServer
 
class StringFunctions:
    def __init__(self):
        # Make all of the Python string functions available through
        # python_string.func_name
        import string
        self.python_string = string
 
    def _privateFunction(self):
        # This function cannot be called through XML-RPC because it
        # starts with an '_'
        pass
 
    def chop_in_half(self, astr):
        return astr[:len(astr)/2]
 
    def repeat(self, astr, times):
        return astr * times
 
server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", 8000))
server.register_instance(StringFunctions())
server.register_function(lambda astr: '_' + astr, '_string')
server.serve_forever()
 

# Client code
 
import xmlrpclib
 
server = xmlrpclib.Server('http://localhost:8000')
print server.chop_in_half('I am a confidant guy')
print server.repeat('Repetition is the key to learning!\n', 5)
print server._string('<= underscore')
print server.python_string.join(['I', 'like it!'], " don't ")
print server._privateFunction() # Will throw an exception
 

I can get XP machines to talk to each other and if I run it on the linux server it connects to itself, but if I try and get XP->Linux or Linux->XP I get connection errors such as

socket.error: (10061, 'connection refused')
or
socket.error: (10060, 'Operation timed out')

If I try and run the server on a port on the linux box and then from xp try to telnet to it, I get
Connecting To Linux-Server...Could not open connection to the host, on port 55670: Connect failed

But if I try to telnet from XP to the server running on a port on another XP machine, I can connect and when I type garbage I get a response, in the form of an error and the server prints out what I typed..
eg response = Message: Bad request syntax ('ssdsadsdasdasdasdasdasdasd')
server message = <my computer> - - [30/Oct/2007 17:06:50] code 400, message Bad request syntax ('ssdsadsdasdasdasdasdasdasd')

So what I need help with is what is going on with the connection between the two different operating systems? Is there anything I can try/read/look at to get this stuff working, as we/I am really stumped here.

I hope I have explained this properly, and someone out there can help.

This really makes me wish that I had a linux box to test this on. The project that I am currently working on may soon need to cross this platform barrier and I'm looking forward to setting one up. But it's crunch time at the moment so that will have to wait a while.
