Ping flood ( ping -f ) vs Default Ping ( e.g ping -i 0.2 )
<p>We currently have a Zabbix app running in CentOS Linux that we use to log our network rtt and packet loss. We came in a internal discussion of what kind of ping we should use</p>

<p>Ping Flood:
ping -f -c 500 -s 1500 -I {$HOSTVLAN2} {$DEST1IPSEC} | grep packet | awk -F" " '{print $6}' | sed -e s'/%//' -e '/^\s*$/d'</p>

<p>'Default' ping:
ping -c 100 -i 0.2 -s 1500 -I {$HOSTVLAN2} {$DEST1IPSEC} | grep packet | awk -F" " '{print $6}' | sed -e s'/%//' -e '/^\s*$/d'</p>

<p>Thats a screen we made to compare results of packet loss:</p>

<p>So we would like an external view of this case. What you guys think about?</p>

<p>We came in several topics regarding network load, DDoS, realiable values of pkt loss etc..</p>

<p>thanks in advance</p>
