Open Stack

Hi,

Sorry my mistake . I was actually trying it for different ports and 
copied the earlier command on client VM. On client VM I am running

iperf -c 192.168.1.42

and on server

iperf -s

yes the server is listening on port 5001.

netstat -anp | grep 5001
(Not all processes could be identified, non-owned process info
  will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:5001            0.0.0.0:* LISTEN      
20227/iperf

Thanks,
Priyanka
