Securing SimpleXMLRPCServer?

[John Abel]

I've set up an server, and client, which works OK, but now I want to
secure the server.  Is there a way I can query the IP of the connecting
client?  I've looked through the documentation, and can see that
SimpleXMLRPCRequestHandler is based on BaseHTTPServer, which has
client_address, but I can't seem to get access that variable.

Any pointers would be much appreciated.
