[Kea-users] problem after upgrade from kea 261

[Darren Ankney]

Hi Ralf,

It seems that you compiled from source as I see you using keactrl to
start the processes?  It also appears that you are root from your
prompt.  One thing you can try is to execute the commands manually
that keactrl shows being executed:

/sbin/kea-dhcp4 -c /etc/kea/kea-dhcp4.conf
/sbin/kea-dhcp-ddns -c /etc/kea/kea-dhcp-ddns.conf
/sbin/kea-ctrl-agent -c /etc/kea/kea-ctrl-agent.conf

But, I encourage you to check apparmor as I suspect that apparmor is
tripping you up.  Debian 12 does not use plain text logs, so here is
how you might check for apparmor problems (as root):

journalctl -xe | grep audit | grep DENIED

There are certainly specific switches to get journalctl to find
exactly what you are after, but the above should work.

A good source of information about apparmor:
https://wiki.debian.org/AppArmor/HowToUse

Thank you,
Darren Ankney
