Unbound is not registering new DHCP lease

[janci]

Hi

I was reporting this issue in 21.7 release. After some time it was fixed.

I did upgrade to 23.1 and and I'm seeing the problem again.

happen just now:
- new device connected to network
- new devices get IP and it can access local network and internet
- I can ping that new device from my laptop BUT only using IP
- if I am using hostname I get error saying not able resolve name ...

I did login to router and run this command:

Code Select Expand

sudo ps -aux|grep unbo
root    88022   5.1  3.3 197748 134948  -  S    Sun14      34:07.57 /usr/local/bin/python3 /usr/local/opnsense/scripts/unbound/logger.py (python3.9)
unbound 84539   0.0  1.4 145996  56208  -  Ss   Sun14       0:38.30 /usr/local/sbin/unbound -c /var/unbound/unbound.conf
root    87907   0.0  0.1  12756   2232  -  Is   Sun14       0:00.00 daemon: /usr/local/opnsense/scripts/unbound/logger.py[88022] (daemon)
jano    95697   0.0  0.1  12748   2364  0  S+   18:45       0:00.01 grep unbo

then I did restart unbound in web gui and run that command on console again:

Code Select Expand


sudo ps -aux|grep unbo

As you can see after restarting unbound service watcher is running. But was not.

Just let me know which log to check (maybe I need to tune log level)  to find out more details so I can help to find out what's going on.

Seeing the same on 23.7.8_1

After random period of time it is working again (DNS resolution).
Please find attached a host monitoring graph (last 35 days) of one access point that periodically is failing for a random time.
The AP was up and running fine all the time, but name resolution via unbound is not possible.

Since I set my dhcpd lease time < 86400 s this did not occur anymore.
