[netperf-talk] How to fix the following error message ?

[Lei Lu]

Hi folks,

I am trying to measure the cpu overhead when the system is sending out
packets with certain rates. To control the packets sending rate, I use the
following command (by changing -b values):

" netperf -t UDP_STREAM -H 172.16.2.150 -b 120 -l 300 -w 10 -- -m 1400 -s
256K -S 256K" (12000pkts/sec)

I have to use the packet size as max as possible, so I choose 1400 in this
case.

The problem is that when I increase the -b values, the following error
message begin to show up:

"UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to
172.16.2.150 (172.16.2.150) port 0 AF_INET : interval
netperf: receive_response: no response received. errno 4 counter -1"

What could be the reason of this error message? How should I fix this one
and continue with my works or is there any pass away method ?

Thanks in advance for any thoughts!
Lei
