Hey Guys;

I guess the best thing to start off would be sending 
'/var/log/ndt/web100srv.log’, it may not have what we need though.  Also send 
the version of NDT you are using, e.g.
 
> [zurawski@localhost
>  ~]$ rpm -qa | grep ndt
> ndt-3.6.5.2-6.el6.x86_64
> ndt-client-3.6.5.2-6.el6.x86_64
> ndt-server-3.6.5.2-6.el6.x86_64

Thanks;

-jason
