[netperf-talk] Built trunk on Windows, OS interoperability

I tried it both directions, so with Windows 2008 as both a sender and as
a receiver.

I was using the most basic:

> netperf.exe -H <ip_of_Linux>
> netserver.exe

And on the linux side...
# netperf -H <ip_of_win2k8>
# netserver

The machines are on the same subnet, firewalls disabled, all that.
I can telnet back and forth on the control port 12865.

Jonathan, a point of interest is that the executables you emailed me
behaved the same as the ones I compiled today; in that they don't pass
traffic when testing between operating systems.  telnet test still
passes.  I understand those exe's work fine for you.

Further oddity, I have netperf 2.4 exe's generated eons ago by a
colleague, and those have no problems between operating systems on my gear.

I suppose I'll setup a Win7 build environment to rule that out...

I have been using netserver on Linux and netperf on Windows without a problem. I built my Windows executable in the Windows XP x86 free build environment and it works on both XP and Windows 7.  You might want to try that.
