Sometimes you need to check the availability of multiple devices using ping. To do this, you can use the fping utility. Example:
fping -f nodes-ip.txt > result.txt
In the nodes-ip.txt file you need to save the ip of the devices, one per line. Next, fping reads the ip from this file and saves the result to another file, result.txt.
Example:
192.168.201.119 is alive 192.168.201.120 is alive 192.168.201.121 is alive 192.168.201.122 is alive 192.168.201.126 is alive 192.168.201.2 is alive 192.168.201.107 is alive 172.17.5.4 is unreachable 172.17.5.5 is unreachable 172.17.5.6 is unreachable 172.17.5.7 is unreachable 172.17.5.8 is unreachable 172.17.5.9 is unreachable
