Hi,

First check if there is another process using the port you connect to on the (other) host. (port 12865)

You run netperf to send data to netserver.

Is netserver running, on the correct port on the other or localhost?

Regards,
Bob

Since the message "establish_control: connect completes" is seen, as well as some messages about exchanging requests and responses, we can be confident that there is indeed a netserver listening on port 12865 on the remote. If there were not, there would be a different message printed.

Some of the changes I made to satisfy those people wanting to run netperf through evil end-to-end breaking things like firewalls.... broke the UDP_STREAM test. There is a 2.3pl1 on ftp.cup.hp.com I believe fixes that problem.

happy benchmarking,

rick "mr netperf" jones

PS, at present, there is no check in netperf for a verbosity level greater than 2 :) (IIRC)

PPS - netperf is not an official HP product. There is a netperf-talk@netperf.org mailing list one can join to discuss netperf. Send email to netperf-talk-request@netperf.org
