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;

-jason


There is a copy of the command line client (diag-client) for npad on
the knoppix disk image. When I run it, it tells me:

[warner@Knoppix usr]$ diag-client 128.193.128.237 8200 Using: rtt 10 ms and rate 20
Connected.
Protocol error: bad handshake.
Please make sure you have the latest client, and you have the correct port number.


That port number works with a browser connection. I'd look for the client version,
but it doesn't seem to have one -- and in any case, I don't know what the current
version should be.

Thanks.
