ndt-users list created

["Alex. S." <>]

Hi,

Since the last week, I had been trying to setup a server to test ndt just for fun.

I tried with ubuntu 8.04 LTS, kernels 2.6.33, 2.6.32, 2.6.31, and 2.6.24 (and their respective web100 patches), web100 userland 1.7, but with varying grades of compilation success I was not able to test ndt on my virtual machine.

At the end, my best shot was a version of ndt server and client (3.6.2b) passing the checks for middleboxes, but failing the client to server and server to client tests with messages like "S2C throughput test FAILED!". The worst cases were when the ndt client didn't even pass the checks for middleboxes with "Checking for Middleboxes Protocol error  missed text message!"

Tonight I'm going to try the instructions at https://wiki.chpc.utah.edu/display/CyberInfrastructureLab/Network+Performance+Measurement+Server+using+Fedora+Core+9 using these exact software versions to see.

Before of that I was wondering if there exists a sort of VirtualBox or VMWare image ready for use with ndt (with the right version of web100). If it is, can you point me to there ?

Why is this compilation so difficult?, Is there any methods to validate if everything goes well in every stage? how can I know if the web100 patched kernel is doing well (besides the message "web100 initialization was successful" in dmesg), how can I check if the web100 userland was correctly installed and if it is functioning properly?, how can I know what to blame in case of something goes wrong?, what are the most "stable" combination of software versions involved to try?


Thank you very much for your time and your responses.
