Using the '' makes it listen on all interfaces.

Okay, I changed this:
server = SimpleXMLRPCServer.SimpleXMLRPCServer((localhost, 8000),

for this:
server = SimpleXMLRPCServer.SimpleXMLRPCServer(('', 8000), )
Replacing localhost with two simple quotes ' makes it work.
Anyone knows the reason for this?

Thank you for the quick reply John...
Is there a way to sort this out? Should I specify another address
here:
server = SimpleXMLRPCServer.SimpleXMLRPCServer((localhost,
8000), )
instead of localhost ?
I'm kind of new to client/server programming, so I'm at a loss here.
Thank you very much for your attention.

Once I execute the program (see below) only one file (instead of x

The program is as follows:

Re: Security on XML-RPC
dcrespo wrote: Hi all, Anyone knows a simpler but stronger control access to XML-RPC functions than the one I comment here? My actual system works like this: I have a TCP Server and an XML-RPC Server. Both of them verify if the IP address is allowed. The TCP Server works for validate and register an IP address if it wasn't validated previously, while the XML-RPC Server works only if the requester IP address was allowed through the mentioned TCP Server. This means, anyone who wants to connect to the XML-RPC Server has to pass the TCP Server. How a client connects to the TCP Server and authenticate his IP? Well, there is an interchange of encrypted data between the Client and the TCP Server, where, in few words, the client sends a UserName and a Password, all this through the send() function of the Socket connection. If the TCP Server authenticate an IP address, then that Client will be able to connect to the XML-RPC Server and use its defined functions. The problem I see here is that if I want someone to taking advantage of my XML-RPC functions, I have to tell him all these. I would like to get a strong but simpler way of doing all these. Thank you for reading and thinking. Daniel Not the most secure, but I have a modified XMLRPC Server/client using Digest auth, if that's any use?

I agree with this too, but if you're a programmer on the Windows platform with possibility to install software on the machine you work with, I strongly suggest that you install cygwin or something equivalent. Not just for man python. Tools like grep and find are vastly superior to anything I've seen natively on windows if you want to process the data you find in some automated way. In my experience, Windows 2000 and later are fairly decent operating systems if you have Python and cygwin installed, but I'd feel awfully handicapped without those tools. As a programmer on Win32, and *nix platforms, I agree with needing better tools. however, I find cygwin a pita. For tools such as grep and find, try this http://unxutils.sourceforge.net/. No need for cygwin ( though that's not say cygwin isn't useful ). J -- http://mail.python.org/mailman/listinfo/python-list
More Rewrite Request Within SocketServer?
OK, I'm guessing what I was after ( see below ) isn't possible. Does anyone know of an easy way of having verify_request inform the request handler of certain events, say client is unauthorised? I thought of having it set a flag, and referring to it from the handler class ( self.server.hostAllowed for example ), but that wouldn't work quite right in a threaded server. Any ideas?

Defunct Processes With subprocess.Popen
Hi! I'm currently writing a script which launches external programs, but it keeps leaving zombie/defunct processes behind, until I kill the launching script, which is a bit of a pain, as it's supposed to be a daemon. The code I'm using is: newPid = subprocess.Popen( cmdLine[ 1: ], executable=cmdLine[ 0 ], close_fds=True ).pid I've tried calling it using the shell=True flag, but that leaves a zombie for the sh, instead. I'm not interested in any output, the only thing I need returning, is the pid of the new process. I've tried using spawn*, with the same results. Does anyone have any ideas? Thanks.
