Script to ping computer

[pturmel]

Add CAP_NET_RAW to your SystemD service's AmbientCapabilities. That will allow .isReachable() to work in a non-root environment. (I recommend also using CAP_NET_BIND_SERVICE so you can use the standard http and https ports with a non-root service.)

Issue with java.net module import in Ignition V 8.1.5

If on Linux and not running as root, use of any ping-like raw packet requires the CAP_NET_RAW capability (privilege). You can specify that in the SystemD service file (or override) with the AmbientCapabilities=CAP_NET_RAW setting. You can specify multiple capabilities with whitespace. I recommend AmbientCapabilities=CAP_NET_BIND_SERVICE CAP_NET_RAW.
