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

My only suggestion is that you verify that you are using the same version of netperf and netserver on both the Linux and Windows machines. You might also use Wireshark to verify that the packets are getting through.
This is what I see when I use the basic commands:
Windows command line:
C:\Program Files (x86)\Netperf>netperf -H 10.8.7.243
TCP STREAM TEST from 0.0.0.0 () port 0 AF_INET to 10.8.7.243 () port 0 AF_INET :

C:\Program Files (x86)\Netperf>netserver

Linux command line:
[demo at appserver ~]$ netperf -H 10.8.7.167

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.
