Hi, list,
I'm using Kea V1.5.0 and running two dhcp servers in Hot-standby mode. My
lease database is Memfile. I setup NTP for both servers.
Here is part of my configuration,
===============
"high-availability": [ {
"this-server-name": "server2",
"mode": "hot-standby",
"heartbeat-delay": 10000,
"max-response-delay": 10000,
"max-ack-delay": 5000,
"max-unacked-clients": 5,
"send-lease-updates": true,
"sync-leases": true,
"sync-page-limit": 10000,
"sync-timeout": 30000,
"peers": [
{
"name": "server1",
"url": "http://172.16.232.18:8080/";,
"role": "primary",
"auto-failover": true
},
{
"name": "server2",
"url": "http://172.16.232.20:8080/";,
"role": "standby",
"auto-failover": true
}
=============
Yet on standby server ,it says that,

============
I'm sure two severs get correct date time. So what's the reason ?
Is it related to

Thanks and take care.
