[netperf-talk] Loopback test on XP "connection forcibly closed"; WDK errors

[Kevin Murphy]

Thanks- I used the netserver.c you supplied and got the exact same results
after running netserver and then netperf on the same machine.

I ran "netserver -v 2 -d" and "netperf" (no options)

The small netperf.debug file in C:\Temp\ is
C:\Temp>type netperf.debug
*Starting netserver at hostname 0.0.0.0 port 12865 and family AF_UNSPEC*
*nfo returned the following for host '0.0.0.0' port '12865' family AF_UNSPEC
*
*        cannonical name: '(nil)'*
*        flags: 4 family: AF_INET: socktype: SOCK_STREAM protocol
IPPROTO_TCP addrlen 16*
*        sa_family: AF_INET sadata: 50 65 0 0 0 0*
*Starting netserver at port 12865*
*CreateProcessfailure: : The system cannot find the file specified.*
*
*
Trying to figure out how to capture loopback traffic on XP with Wireshark.
Not easy.

Will try to run on two different servers.

If anyone has 2.4.5 running on XP SP 2 or 2K3 binaries appreciated.

Thanks - kevin
