Hi Martyn;

The easiest thing to do is:

1) edit the src/web100srv.c file and add the missing shutdown() line (see 
my previous email on where this line goes).

2) save the file and then run the make and make install commands.  This 
will update the server processes but it will not disrupt the customized web 
page.

3) then kill and restart the NDT server processes, the easiest way is to 
run the "conf/ndt restart" command or you can kill off the web100srv and 
fakewww processes and run the conf/start.ndt command again.
