Ping node doesn't work in node-Red

I have made a complete reinstall of my AXC F 2152, starting from factory default.

Then, FW 2019.3, then node.js from the PlcNetx store, and then, node-red.

Then, I install ping node from the node-red palette.

Here is the result :

2019-05-15T09:57:17.180Z Install : node-red-node-ping 0.0.16

2019-05-15T09:56:50.124Z npm install --no-audit --no-update-notifier --save --save-prefix="~" --production node-red-node-ping@0.0.16
2019-05-15T09:57:25.541Z [out] + node-red-node-ping@0.0.16
2019-05-15T09:57:25.541Z [out] added 1 package from 1 contributor in 14.572s
2019-05-15T09:57:26.244Z rc=0

So then, as the result code is correct, I think the node will work correctly.

So, I create a simple ping node connected to a debug node :

[{"id":"dcb4bee1.e30e1","type":"debug","z":"c71d23e6.4d3ab","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"payload","targetType":"msg","x":611.53125,"y":301.9375,"wires":[]},{"id":"ea125913.57d348","type":"ping","z":"c71d23e6.4d3ab","name":"","host":"www.google.com","timer":"5","x":407.7890625,"y":304.7734375,"wires":[["dcb4bee1.e30e1"]]}]

 

And I get this reply in the debug node :

15/05/2019 à 12:03:35node: ea125913.57d348msg : string[29]

"ENOENT ping command not found"

 

Of course, when I use a ping in the console, it succeeded :

admin@axcf2152:~$ ping www.google.com
PING www.google.com (172.217.22.132): 56 data bytes
64 bytes from 172.217.22.132: seq=0 ttl=47 time=15.803 ms
64 bytes from 172.217.22.132: seq=1 ttl=47 time=14.257 ms
64 bytes from 172.217.22.132: seq=2 ttl=47 time=13.349 ms

I really don't understand why that fails, and waht i can do.

I tested the same thing with an exec node, making a ping, and i have the same result.

An advice?

Thanks

    Hi Michel,

    sorry but at least we from the PLCnext support team are not that deep into node red.

    It might be the best when you just raise a question on stackoverflow and tag it with "node-red".

    I'm sure that you'll get a fast feedback there.

    Take care

    Frank

    Hi Michel,

    To Ping, you can use the 'Exec' node and in command parameter: /bin/ping 'IP Address' and '-c 4' in 'extra input parameters'.

    Regards,

    Amilton.
