System Function for pinging an IP through script

[pturmel]

Follow Tyler's instructions here:

Script to ping computer

Here is a lengthy recap of the steps that lead to success in using java.net (InetAddress, isReachable) on a Linux server (Ubuntu 20.04.5 LTS) with Ignition running as a non-root system user account. Ran this command... sudo systemctl edit Ignition-Gateway.service Added this text... then saved changes. [Service] AmbientCapabilities=CAP_NET_RAW CAP_NET_BIND_SERVICE Restarted the Ignition gateway... sudo /usr/local/bin/ignition/gwcmd.sh -r Confirmed the service was running without err…

I highly recommend not shelling out to the system's ping executable.
