<p>I discovered what I think may be a very obscure bug in 1.0.0 having to do with OFFER replies meant for VMs running on hosts on VLAN trunks (no seriously), so I wanted to check the latest version of the project to see if it’s already been taken care of. I set up a lab system, cloned the repo and made a build with –with-dhcp-mysql. I set up a new database with dhcpdb_create.mysql from Github and inserted a host according to <a href="https://kea.isc.org/wiki/HostReservationsHowTo">https://kea.isc.org/wiki/HostReservationsHowTo</a>.</p>
<p>This test server will happily serve up pool addresses (and will stash the lease info in MySQL, so the database connection is for-sure working) but it completely and obstinately ignores the contents of the hosts database table. I’ve tried both same-subnet and through-a-relay clients and the server claims to be unable to find a host for hardware address such-and-whatever.</p>
<p>Here’s the relevant part of my config file:</p>
<pre><code>"interfaces-config": {
"interfaces": [ "eth0" ],
"dhcp-socket-type": "raw"
},
"lease-database": {
"type": "mysql",
"name": "[REDACTED]",
"host": "[REDACTED]",
"user": "[REDACTED]",
"password": "[REDACTED]"
},
"hosts-database": {
"type": "mysql",
"name": "[REDACTED]",
"host": "[REDACTED]",
"user": "[REDACTED]",
"password": "[REDACTED]"
},
"expired-leases-processing": {
"reclaim-timer-wait-time": 10,
"flush-reclaimed-timer-wait-time": 25,
"hold-reclaimed-time": 3600,
"max-reclaim-leases": 100,
"max-reclaim-time": 250,
"unwarned-reclaim-cycles": 5
},
"option-data": [
{ "name": "domain-name-servers", "data": "[REDACTED]" },
{ "name": "domain-search", "data": "[REDACTED]" }
],
"valid-lifetime": 3600,
"subnet4":
[
{
"id": [REDACTED],
"subnet": "[REDACTED]/24",
"valid-lifetime": 3600,
"option-data":
[
{ "name": "routers", "data": "[REDACTED]" }
]
}
]
</code></pre>
<p>And here’s the SQL statement I used to insert the host reservation:</p>
<pre><code>INSERT INTO hosts (dhcp_identifier, dhcp_identifier_type, dhcp4_subnet_id, ipv4_address, hostname) VALUES (UNHEX(REPLACE('[REDACTED]', ':', '')), (SELECT type FROM host_identifier_type WHERE name='hw-address'), [REDACTED], INET_ATON('[REDACTED]'), '[REDACTED]');
</code></pre>
<p>Am I doing something wrong?</p>
