I issue a node-red-start on raspberry pi 4 32G SD, and I get a "not running on a pi"  
on a freshly initialied sd from the bash command in node-red documentation.  
I get a warning :  
Not running on a Pi - Ignoring node !!  
it is running on a Pi.

(fileServer listening on ip 192.168.1.91 and port 8098 . it is the ip of the raspberry running nodered. )

and finally it sends a message and reboots !!!

I am a bit clueless... I cannot isolate the problem easily, I would try disabling the flows on by one, but I cannot run the server!

I re imported a project which worked fine.. and this occured after a minor change.

thanks for any lead.

```auto
pi@raspoutine:~ $ node-red-start

Start Node-RED
 
Once Node-RED has started, point a browser at http://192.168.1.91:1880
On Pi Node-RED works better with the Firefox or Chrome browser
 
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
 
To find more nodes and example flows - go to http://flows.nodered.org
 
Starting as a systemd service.

Are you running node-red as root/sudo?

Have you opened firewall port and/or port forwarded to expose node-red to the internet?

This message smells like an intruder.

You can run Node-red in safe mode `node-red --safe` which will run the editor but not start any flows.  
That should allow you to look for a cause of the reboot.  
Probably a good place to start is Search Flows to find Exec nodes.

It might be wise to investigate with the Pi disconnected from your network.

Great suggestion. I will try that !!  
I use vnc (headless raspberry), so I need my local network..  
Thanks!

It is run as pi user. when I : ps -aux | grep node-red  
pi 2235 34.3 1.9 5181028 153272 pts/0 Sl+ 18:45 0:08 node-red  
... Maybe a node was installed as root...  
anyway it is a good lead --- thanks

Not on this one, (port forwarded only on another one (raspberry) which is protected).

Intriguing... (intruder...)  
Thanks..

Have you got the pi setup to require a password for sudo? If not then do so. Otherwise a flow can inject any command it likes, possibly destroying your system.

Hi Colin,  
it is in fact setup NOT to require a password.  
so I set it up requiring a password.

```auto
sudo nano /etc/sudoers.d/010_pi-nopasswd
There's only one line:
pi ALL=(ALL) NOPASSWD: ALL
Changed it to
pi ALL=(ALL) PASSWD: ALL

```

now  
sudo -p [password] [command]  
works fine  
thanks.

Can you share what was causing the reboot?  
It might help other people.
