Re: [Kea-users] migrating from DHCPd to Kea

2024-04-16 Thread Brendan Kearney


Peter,

thanks for the quick reply.  please let me know if there is more detail 
needed.  i run Kea with ERROR level logging, so if more verbose logs are 
needed, i would need to set up some time to test and collect the logs, etc.


the logs from the testing i did, as collected by my syslog receiver:

Hi Fabio,
  If you are building Kea from source, you will need to rebuild the 
binaries if any dependencies are updated.


Kind Regards Peter

Re: [Kea-users] migrating from DHCPd to Kea

2024-04-16 Thread Peter Davies


Hi Brendan,
   Kea will not be able to grant leases if it cannot contact its lease 
database.

Your configuration file and logging would be helpful.

Also, setting  the "authoritative" to true will force Kea to always 
reject INIT-REBOOT requests from unknown clients

list members,

i am trying to migrate to Kea and have 2 HA+MT instances stood up.  
when i start relaying dhcp requests to Kea, i get bunch of failed 
attempts to obtain leases on the clients, which i believe is due to 
the clients not having active leases from Kea.  i am wondering if 
there is a means to have the clients get new assigned leases without 
having to jump through hoops like reboots.


as an aside, i also find the below error in my logs, which seems to 
indicate a malformed database query.

connection to server during query (error code: 2013).


the select, if pasted into any mariadb client, fails since the "?" is 
not proper syntax.  i dont know if the behavior i am seeing with the 
clients not getting new leases and the database error above are 
related or if there are a couple of issues to be worked through.


what info should i provide, to understand where i have issues to 
address?  i am running Kea 2.4.0 on fedora 38.


thanks in advance,
