Network IP Scan in Script fails

[xtomiff]

I tried to run the script from https://github.com/bbird81/Netbox-ipscanner/blob/master/netbox_ipscanner.py in my netbox.
Unfortunately the networkscan only works with the root user, but not with the netbox user. When I run the script in the GUI, all the subnet scans returned are empty. "No host found in network 10.x.x.x"

When I run the networkscan.py script as root it gives me back the correct IP's on the subnet. So it's not an issue of installed software.

When I try to run the script as root in the CLI I get the
File "/opt/netbox-4.2.8/venv/lib/python3.10/site-packages/django/db/models/query.py", line 649, in get
raise self.model.DoesNotExist(
extras.models.scripts.ScriptModule.DoesNotExist: ScriptModule matching query does not exist.
Error.

What am I missing? Is it a rights issue?
I run my Netbox in an ubuntu container on Proxmox - no Docker or similar.

As I only need the IP-Ping functionality, I don't need any suggestions for Slurp'it or Diode. Thanks :-)

I could solve this:

You need to add the line
net.ipv4.ping_group_range = 0 1000

to the file /etc/sysctl.d/99-sysctl.conf to allow non-privileged users to make pings.
