If you run `ss -nulp` does it show the interface that would be receiving those
DHDP discovers from the relay listening on port 67?

Subject: [Kea-users] kea dhcp4 not responding to requests
[EXTERNAL EMAIL]
list members,
i am working to convert from dhcpd to kea, and have the configs i think i want,
but in testing, the kea-dhcp4 instances are not responding to relayed requests.
i have dhcp-socket-ype set to UDP, so relayed packets should be responded to,
as well as declaring the relay/ip-address in the subnet definition. i can see
the relay send the dhcp packets, and the hosts running kea-dhcp4 see the
incoming packets, but there is no indication that kea is accepting the packet,
much less responding to them. tcpdump shows no response and running kea-dhcp4
in the foreground does not show anything past the startup of the listener. it
seems i have some odd config that is preventing kea from acknowledging the
incoming request.
i can post the config json, the debug output or whatever else is needed, but
how do i find out why the listener is started but not accepting incoming
requests?
thanks in advance,
brendan kearney

thanks, matt. i needed to adjust the loggers config, so that my logs
went to stdout when debugging. the boxes are listening on port 67, and
tuning the loggers showed the traffic. now i am on to why things bomb
out when i try to cutover all dhcp traffic to kea.
