[Kea-users] error message

[Peter Davies]

Hi Christian, 
The incoming request was from 172.21.11.104, and the lease request is for 
172.21.11.104. 

I don't know what the request packet contains, but Kea tries to send the reply 
to 255.255.255.255 - this is a Limited Scope Broadcast Address; unlike other 
types of broadcasts, packets sent to 255.255.255.255 do not pass through routers. 
Therefore, it's confined to the sender's local network segment. 

If the client with mac address b8:27:eb:12:96:74 is located in the same broadcast 
domain as the Kea server, you will need to define "dhcp-socket-type": "raw". 

See: https://kea.readthedocs.io/en/kea-2.6.1/arm/dhcp4-srv.html#interface-configuration

Hi Peter, 



Dhcp-socket-type is: 

"dhcp-socket-type": "udp" 



Kea is running as user “_kea”, installed on debian with the subscriber package from isc in version 2.6.1. 

In general kea works, but some clients get this error. 

I’ve shared the config in this thread on the email before to Darren. 



Best regards, Christian

Hi Christian, 


What is the value of "dhcp-socket-type" in your "interfaces-config" definition? 





Also, what users are you running Kea as? If Kea is not run as root, there may be 


permissions issues.
