Peter;

Thanks for the feedback and pointer to the howtoforge web site.

The NDT server is designed to run a quick test and then use the 
Web100 statistics to analyze the test results.  While you can extend 
the test length, I don't recommend it.  However, if you do make 
changes, please consider sending them back to the ndt developers for 
inclusion into the contrib directory.

There are several points in the code that need to be modified to 
increase the test time.  Both the client (applet and command line 
version) and the server have timers to prevent the system from 
hanging.  For example the Applet contains several calls to the 
setSoTimeout() function to set a watchdog timer for each test.  There 
are similar alarm() function calls in the command line client and 
server code.  You will need to reset these watchdog timers along with 
the specific test time if you want to increase the test time period.

I would be happy to talk with your network engineers if they want 
more details about what the NDT system is doing and why 10 second 
tests are reasonable.

Rich Carlson
