Hi atomlab,

Thanks for your help! :)

But I still have the same problem..

/usr/local/sbin/web100srv -r -d

Do you have any idea? :(

Hi. I have faced the same problem.
NDT  v.3.4.6

The option "record_revers"  should help to solves this problem

$ man ndt.conf

record_reverse  (6)  -  This boolean flag causes the web100srv program to
retrieve and store the Web100 variables while performing  the client to server
throughput test.  Replaces -r option.

$/usr/local/sbin/web100srv -a -4 --multiple -r

All works!
