🚨 ALERT: Python execution capabilities (NET_RAW/NET_ADMIN) are missing.
The Python binary in this image has file capabilities (+eip) that
require these bits in the container's bounding set. Without them,
the binary will fail to execute (Operation not permitted).
Restart with: --cap-add=NET_RAW --cap-add=NET_ADMIN

══════════════════════════════════════════════════════════════════════════════
⚠️ WARNING: Reduced functionality (NET_BIND_SERVICE missing).
Tools like nbtscan cannot bind to privileged ports (UDP 137).
This will reduce discovery accuracy for legacy devices.
Consider adding: --cap-add=NET_BIND_SERVICE

⚠️ WARNING: ARP flux sysctls are not set.
Expected values:
net.ipv4.conf.all.arp_ignore=1
net.ipv4.conf.all.arp_announce=2
Note: If using 'network_mode: host', setting these via docker-compose sysctls
requires the NET_ADMIN capability. When granted, these sysctls will
modify the host namespace. Otherwise, you must configure them directly
on your host operating system instead.
Detection accuracy may be reduced until configured.

I also get this same error when running NetAlertX from the HA side bar, but it runs fine when clicking "Open Web UI" from the Settings>Apps>NetAlertX

Hi,
Thanks for the update and no issue with update to 26.3.16-6. Alert on python is always present in log file, but I can see the interface
