A fresh install of NodeRED 2.1.4 at Ubuntu 18 LTS. It seems that it works but...
If I use ping node (this one node-red-node-ping (node) - Node-RED) or config ping (this one node-red-configurable-ping (node) - Node-RED) I get very wierd results when I ping some devices at my own network. I can receive values like 0.452 as well as 238 from the same device.
And if I ping the same device from Ubuntu terminal - I get normal results like 1.85 with deviation 0.5.
What can be wrong? I don't use Ubuntu Snap, Docker or everything.
Tried to use Advanced Ping the same result. It gives more or less correct results. But then provides bad results like 224 ms.
PS. I use english version of OS.
PSS. I did a small investigation. Review the code of the node, found the command promt for Linux. Try to execute in in terminal.
If I use ping -n -4 -w5000 192.168.8.223 and it pings without any stop then I receive good ping results. But if I run several times ping -n -4 -w5000 -c1 192.168.8.223 in a raw then I receive very different results including these strange and large responses like 224.
