Hi Laurie;

OK, this is a known issue.  The 3.3.x series of NDT package has a bunch of 
changes including IPv4/v6 addressing and a new Firewall Detection 
mechanism.  These changes make the 3.3.x client incompatible with older 
3.1.x servers.  The Java client isn't effected because it is downloaded on 
demand when the client connects to the server.  However the command line 
client will fail.  The client does attempt to detect and report this 
condition so you have some idea of what happened.

The Abilene NDT servers are still the old 3.1.x servers.  You can try 
testing to the web100.internet2.edu server, or some of the remote servers 
that I know have upgrades (SWITCH, NSF, and Stanford).  Or you can grab one 
of the older ndt packages if you want to test to an old server.
