I remember reading somewhere that you can’t do ICMP without root. This is for my home maker project that I am switching from node-red to Ignition since I’m using Ignition at work, and since there is so much mu UI support. So I guess for now I just won’t run it in a container until if/when this gets worked out. Thanks for all the input on this!

BTW I tried the ping function mentioned above in the script tool, and that works, just like the popen works. Is that jython running as root?

I changed the title of this to more accurately reflect what it is addressing.
