What Others Think

Mines much faster, but the setup time is longer. (Pings my 40 hosts in about 4 seconds on average) Initial file- #!/bin/bash target=$1 count=$( timeout 0.2 ping -c 1 $target | grep icmp | grep bytes | wc -l ) if [ $count -eq 0 ] then echo -e "\e[1;91m Host is not Alive! Try again later..\e[0m" else echo -e "\e[1;91m IS Alive \e[0m" fi Secondary File with all the hosts you would want to ping. echo "Identity" &&./[Name_Your_Script].sh 0.0.0.IP_Address

The port is covert because the tool must wait for each request to clock out before closing it, which might take a few seconds apiece. To counteract this, the SolarWinds Port Scanner employs multithreading, scanning several ports and/or IP addresses simultaneously.
