Hi Dimitrios;

The short answer to your question is no, the bwctld.limits file controls 
the BWCTL tool, not the NDT tool.  The NDT tool only runs a series of fixed 
duration TCP tests.  There are some configuration options (see the 
ndt.config man page for more details), but UDP testing is not one of these 
options.

The Knoppix-based NPT (Network Performance Toolkit) Live-CD contains 3 
Intenet2-based tools BWCTL, NDT, and OWAMP, along with PSC's NPAD tool, and 
other tools may be added in the future.  Each tool can provide a different 
view of your network.  Combining these views can help the network 
administrator quickly and easily find/ifx network problems.

Details for all of these tools can be found at the Internet2 E2E web site 
http://e2epi.internet2.edu/  Follow the sidebar links to learn more about 
each tool. Each tool contains it's own configuration file.

I hope this answers your question.

Regards;
Rich
