Hi Jim;

The NPAD server's HTTP port listens on 8200, the connect port for actual 
NPAD tests is 8100:


[knoppix@Knoppix
 ~]$ diag-client 128.193.128.237 8100
Using: rtt 10 ms and rate 20
Connected.
Control connection established.
port = 8003
Starting test.
Parameters based on 108 ms initial RTT
peakwin=27400 minpackets=3 maxpackets=83 stepsize=8
Target run length is 608 packets (or a loss rate of 0.16447368%)
Test 1a (11 seconds): Coarse Scan
Test 1b (11 seconds): ...
...


Thanks;
