xml-rpc, O'Reilly cookbook example not working???

[Meehan, Francois]

Hi all,

In the process of learning Python, I bought the O'Reilly cookbook. I am
curious about xml-rpc, tried the example 13.2 and 13.3, they worked as long
as the client and server were on the same machine. Since rpc stands for
remote procedure, I tried to run with the client and server on different
machines. 

The server does not respond to remote query, did also try telnetting the
ports, always gets "connection failed".

Any ideas?

Here is the first example code: 

# server coder sxr_server.py
# needs Python 2.2 or the XML-RPC package from PythonWare

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 directly through XML-RPC because
        # it starts with an underscore character '_', i.e., it's "private"
        pass

    def chop_in_half(self, astr):
        return astr[:len(astr)/2]

    def repeat(self, astr, times):
        return astr * times

if __name__=='__main__':
    server = SimpleXMLRPCServer.SimpleXMLRPCServer(("localhost", 8000))
    server.register_instance(StringFunctions())
    server.register_function(lambda astr: '_' + astr, '_string')
    server.serve_forever()
