Node-red-node-ping always return false

General
1

Hello,

I am new to node-red. And new to this forum too! In the links please replace "-" with "." :slight_smile:

For learning purposes I want to try ping a target and show the result on an dashboard :slight_smile:

I use "node-red-node-ping" and hoped to get the Roundtriptime in ms as msg.payload. But I was wrong...

The following targets are "not pingable" and I get "false" as return value:

(IPVx = Automatic or =IPV6)
www-google-de
google-de
localhost
heise-de

The following URL does work correct:
(IPVx = Automatic)
ipv4-google-com

(IPVx = IPV4)
heise-de

For me it seems that ping to IPV6 targets does not work correct.

My Desktop is a Windows 10 with IPv6 as default.

Please try to reproduce. And If you have a hint for me I would be very thankfull.

Kind Regards
Rainer

Does the command line ping command work with ipv6?

3

yes in the "cmd" Commandline everything works fine

4

I thought it was necessary to use ping6 for IPV6 addresses.

Hello Colin,

what do you mean with "ping6"? This is not an windows cmd command nor an node-red task.

6

Linux = ping6
Windows = ping -6 [IPV6 address]

7

Have you tried both options ?

@dceejay,

yes I tried IPV6 also and for better reading. I edited the original Forumstext.

@edje, Colin11: ping -6 force the usage of ipv6 but in my environment it is not necessary cause my host use ipv6 as default. ping -6 does work correct :slight_smile:

Which version of node-red, nodejs and node-red-node-ping are you using?
node -v to get nodejs version.

It is working ok for me on Ubuntu, specifying my own ipv6 local address.

10

Node-RED version: v2.1.3
Node.js version: v16.13.0
Windows_NT 10.0.19042 x64 LE

node-red-node-ping 0.3.1

Everything installed on Monday (this week).

11

Is your system set up to use IPV6?

12

Hello ghayne,

my Desktop is a Windows 10 with IPv6 as default.

13

ipv6

Yes, it looks as your screenshot :slight_smile:

15

Just a thought :slight_smile:
[edit - I missed that you had done it successfully from the command line!]

16

Can you post your flow please.

17

Do you mean export and upload?
