Since there is something running on port 7123, the "does not support this 
command line client" seems a reasonable error message to me. Would you prefer 
it say "The server 'ndt.iupui.mlab1.lga01.measuremnet-lab.org:7123' does not 
support this command-line client"?

I understood it to mean that there was a version incompatibility and that if I 
had a client that matched the server it would work, but maybe that's reading 
too much into it.

I would expect an error more like "The server 
ndt.iupui.mlab1.lga01.measuremnet-lab.org:7123 does not appear to be an NDT 
server."
