Hi Benchmarkers,

I am new to netperf, so please bear with me.

I am trying to run netperf-2_1pl1 and netserver-2_1pl1 (binaries for
Win32) between two Windows 95 PC's, equipped with ForeRunner PCA-200E
ATM adapters. (The PC's are connected via an ATM switch). For TCP_STREAM
tests, everything works 'as advertised'. However:

- when I try UDP_STREAM, netperf prints the following message on the
line following the banner:
'send_udp_stream: error on remote: Unknown error'

(Since I have an HP Internet Advisor monitoring the link between one of
the PC's and the ATM switch, I can observe that data is actually being
sent at the expected rate).

- when I try TCP_RR, netperf prints after the banner:
'netperf: remote error 10038Unknown error'

- when I try TCP_CRR, I get:
'netperf: receive_response: no response received. errno 0 counter 0'

Any clues as to what is going wrong? Are these all symptoms of the same
problem?

Any and all help appreciated...
