Hey Richard,

This is great work. Thanks for doing it! One question I had, would it be possible to split out the three different things covered by the patch into three separate patches (i.e. kernel mode setting, bugfix for the issue you reported, and the web10g changes)? It'd make it a bit easier to review each.

Cheers,

Aaron

Hi,

As part of an internship at WAND, I've been working on a web10g version of ndt.

The patch is attached.
I've also got some Web10g patched linux kernels for Debian(squeeze or wheezy should work) here.
https://docs.google.com/folder/d/0B-PiO7DvhNkJUDNwcTZjVGtJNmc/edit

NOTE: The kernel needs a slight modification to the Web10g kernel patch. Which is included in the Google drive folder above.

I've incorporated Web10G into the code in such a way that both the web100srv and web10g can be built. Besides some bug fixes the web100srv is unchanged. The configuration process should detect web100 and web10g libraries and build accordingly. Web10G variable logging is not implemented - this shouldn't have any effects on the results.

For the most part the client hasn't been changed, so an old client can connect without issues. The only things that could go wrong with an old client are TCP Timestamps/ECN may be incorrectly detected as on.

This patch also includes a few fixes for both clients and servers, including those I logged as issues #69 #70 #71 #73.

Along with web10g this adds code in ndt/src/kernel_* files which will check some of the kernel configuration for a Web10G server and print warnings about incorrect configuration.(If the server is run with -k option these will be corrected).

Look at ndt/WEB10G README for more information.

I would be great to get this incorporated into the ndt trunk (or branch). Although the Web10G code still needs more testing the web100 parts of the code are unchanged.

Send me an email if you have any issues all feedback is welcome.

Cheers,

Richard
