nmap fails to obtain mac addresses on

[cometchaser]

The problem

Hi

I wanted to use the Nmap Tracker to monitor my network. However, no devices are found. I am using Homeassistant in version 2024.8.0.

In the logs I only find the note that no MAC address was found for the respective devices:

2024-08-11 10:24:12.506 DEBUG (SyncWorker_0) [homeassistant.components.nmap_tracker] Scanning ['192.168.2.0/24'] with args: -F -T4 --min-rate 10 --host-timeout 15s --exclude 192.168.2.254 --reason -v
2024-08-11 10:24:35.237 DEBUG (SyncWorker_0) [homeassistant.components.nmap_tracker] Finished scanning ['192.168.2.0/24'] with args: -F -T4 --min-rate 10 --host-timeout 15s --exclude 192.168.2.254 --reason -v

2024-08-11 10:24:37.362 INFO (MainThread) [homeassistant.components.nmap_tracker] No MAC address found for 192.168.2.3

This problem looked similar to #87623. But this one should be solved.

I tried to fix my problem by following https://github.com/home-assistant/core/issues/87623#issuecomment-1422701870 and add

import getmac
from getmac import get_mac_address
getmac.getmac.FORCE_METHOD="ArpFile"

to /usr/src/homeassistant/homeassistant/components/nmap_tracker/__init__.py. But it doesn't fix to problem. Also the installation of apk add arping doesn't fix the issue.
