OK, great.

This sounds like a port permissions or firewall problem.  The NDT system 
uses 2 server processes
        fakewww (TCP 7123)      This process handles the web services.  You
                                can run a real web server or this simple 
server.
                                The default port is 7123, and you can 
change it
                                with the -p option

        web100srv (TCP 3001, 3002, 3003)
                                This process handles the testing and analysis
                                functions.  The applet connects back to the
                                server on port 3001.  Once connected the 
applet
                                opens 2 more data connections, one for each
                                test.  The server, and any firewall box in 
front of
                                it, must allow connections on these 3 ports.
I suspect that there is a firewall filter that is blocking ports 3001 - 
3003.  The message above indicated the connection on port 3001 failed.  I 
need to improve the error reporting message.

Yes, this just says the web100srv process is running and a test request was 
received, but no test was performed.
