The MMP ping area was never an officially supported area, I’m not very surprised it does not work on EPIC (Linux vs Coldfire).
Any chance I could talk you into using Node-RED for ping? (Way easier than PAC Control - in regards to ping).
For the network stuff, its not in the API (at the moment), so again, its all there in Node-RED.
See this flow as a good start. (I know, its RIO, but it works the same in EPIC).
Let me know exactly what your looking to do / find and we can see what we can do if you are open to using Node-RED.
