title: iperf error: connect failed: no route to host
body: <p>I have installed same version of iperf (2.0.5) on 2 different ubuntu systems.
  But when i execute command <code>iperf -s -p 45678</code> on one system and <code>iperf -c 172.18.41.17 -p 458 -t 10</code> on another system. It gives me error "connect failed: No route to host".</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>EDIT: One system is working as server but the same system is not working as client.</p>
