Access to Red Node via ip adress:1880

Hello
I'm very new to Venus OS large, just installed it and try to connect to signal K and Node Red to have a look. Unfortunately I'm not able to connect to the Node Red server at all. Seams there is a mistake I do. May someone can help me out, as I could not find any further infos.
I tried:

- via venus.local:1880
- via IP:1880

but both does not work at all. I'm able to connect to signalK via both methods :3000

I tried with switched on both signalK and Node Red and just one.
I tried on different browsers, all the same "access denied" error.
As it works with SignalK :3000 I'm don't believe it has something to do with browser setting.

Thanks for your help

Hi @Silvio Franceschini,

did you reboot after activating node-red?

Anything in /var/log messages?
Is node-red running? Login to the console and type in

ps | grep node-red

@Stefanie

Thanks for reply and help

I reboot and change OS back to original and back to large OS, switched on and off Node Red and reboot.


Now I can’t follow you anymore. Not to much into console etc. I know about them on a computer can use it a bit, tried to find something about venus OS commands etc. online but I guess it exceeds my knowledge.

looked trough some of the manuals but I’m probably more on the enduser side as development.

Looks I need to change to "super user" and create a password etc?

Not sure you want to guide me through all of this. but if you can advice which manual may can bring me forward, would be cool. Gracias

It's not that difficult.

Yes, to get root access you need to set access level to superuse, create a root password and enable sshd.

Here is the guide how to do this: Venus OS Root Access

Once you have access vis the console, follow my questions from the other post to make sure node-red is running.

Hello again

Have setup root pw and enter via terminal console, easy. but now :-)

root@einstein:~# ps | grep node-red

830 root 1604 S supervise node-red

1450 root 1748 S multilog t s25000 n4 /var/log/node-red

5175 root 102m R node /usr/lib/node_modules/node-red/red.js

5388 root 2684 S grep node-red

root@einstein:~#

To enter the var/log directory I fail. Got some lists with terminal commands, tried around with cd.. , cd/ , ls , etc was not working at all :-/

only thing worked was:

root@einstein:~# pwd

/home/root

Also tried again to reach :1880

Thanks -

Please confirm exactly which large image FW image you have installed (provide the file name) and what GX device you are using - there was an issue with a recent FW preventing NodeRED access on VenusGX devices, this issue was rectified in the very latest available large image FW.

PS. I have also moved this question into the 'Modification' section.

Thanks for that, also to Stefanie.

Sadly can not post my answer in the comments. nothing happens after press publish ??

I run it on a cerbo GX and use the "venus-swu-einstein-20210113205511-v2.70_3-large-12.swu" which I guess is the latest version.

I have the same problem accessing Node Red offline. Unfortunaly I have no internet connection on site. I suspect that the software want to acces https://registry... but can't. The device is a Multiplus GX with a nanopi, large image version 16 and later on version 17. I had no problem on my test setup with a raspberry pi 4 device, however this rpi4 has access to the internet.node-red-nanopi.png
