Problem with DNS resolver

stephenw10 · Jun 6, 2024, 12:22 PM

Run pkg upgrade to check if there are any updated system packages available.

We build newer versions of packages if they are available with fixes for specific issues that users may be hitting. They are then available to upgrade to but these are not expected or required upgrades.

In the instance that upgrades are required for security issues we would usually either issues an announcement or a point release of pfSense depending on the severity.

I would not expect the Unbound version to be the issue here. But it also doesn't hurt to update it and it's an easy test.

Yup, you can upgrade curl. But not upgrading it should not be an issue.

disabled DHCP Registration

Rebooted the system and the problem recurred. unbound DNS Does not resolve

stephenw10 · Jun 6, 2024, 4:03 PM

And it's still just continually restarting?

Is there anything in the main system log that's looping? Something else could be restarting Unbound.

Unoptanio · Jun 6, 2024, 4:08 PM

@stephenw10

I stopped the service and restarted it and it worked right away.

But in the service list it always showed it running green even when it's not working

stephenw10 · Jun 6, 2024, 4:13 PM

And in the main system log?

johnpoz · Jun 6, 2024, 5:07 PM

@Unoptanio why/how can you have both unbound 1.18 and 1.19.1 on the same system both starting?

Did you upgrade pfsense? That is a pretty fast upgrade

LIke 1 minute?

stephenw10 · Jun 6, 2024, 5:39 PM

Huh, nice catch! Well that seems suspicious!

@stephenw10

Latest updates on the situation:

This morning I restarted pfsense at 06:30AM

After the first restart, the unbound DNS in the service list is displayed with a working green icon.
But it's not actually working.
I did a manual restart of the service and it started working.
This problem occurs every time I restart pfsense.

Below is a log made at 08:45 AM showing the two startups of the service just described

Using the "pkg search unbound" command we discovered that my pfsense 2.7.2 had DNS unbound version 1.18.0_1.

Using the command "pkg install unbound-1.19.1" I installed the new update to version 1.19.1

I did a system reboot.

Throughout yesterday the log showed the two versions but I think it's normal, there are times that demonstrate the relevant version at that moment.

Using the command "cat /var/log/resolver.log | grep 'start'" I can see that only version 1.19.1 appears in today's logs

I had also disabled DHCP Registration in Unbound DNS because it caused the service to continually restart.

The situation has improved, there are no longer continuous restarts of the unbound DNS service and we also have the latest version 1.19.1.
What can I do to resolve the problem that after the first start of pfsense the unbound DNS does not work (even if in the list of services the unbound DNS appears with a working green check box icon) and I have to restart the service manually?

Thanks to you I discovered another interesting command "pkg upgrade" which checks if there are updates on all packages

The situation has improved, there are no longer continuous restarts of the unbound DNS service and we also have the latest version 1.19.1.

So this was the real culprit ...

Maybe enable verbose logging to see if there is a hint in the log what is causing unbound not to start properly ...

Where do you enable verbose logging?

Don't worry about this one. The domain "mobile-webview.google.com" doesn't exist ....
I've tried several revolvers world wide : not found.

@Unoptanio said in Problem with DNS resolver:

You've set yourself "mobile-webview.google.com" as filterdns is trying its out most best to resolve it.
Not very useful.

This line can create 'huge' problems with DNS :

@Unoptanio said in Problem with DNS resolver:

Jun 7 07:00:02 filterdns 37407 Adding Action: pf table: Block_Facebook host: web.facebook.com

Read this : Aliases.

This is a typical case of :

Where "not useful" is an understatement.
When a typical *.facebook.com host name is resolved, it will return many, like a lot, of IP addresses.
The filterdns process is executed every xx seconds or so to update the relation 'host name' => IPs. If the list with IP changes, and it will change constantly, the firewall is reload, .... and process (like unbound) get restarted.
Do you see where this is going ?

Remove all your references to google or facebook in your aliases tables. If you need to filter these, use pfBlockerng.
Your unbound will say thank you to you.

Disable unbound listening on the WAN and see if it stays up.

Yeah the first thing I would do is remove those two failing hosts that don't exist.

Ok!. It seems like everything is working fine now.
I restarted the PC at 7:00 am.
After the reboot everything works fine.
Unbound DNS works.

In summary: steps to solve the problem

Disabled DHCP Registration in DNS Unbound (caused continuous restarts of the service)
Disable unbound listening on the WAN (caused the service to be restarted twice)
It is recommended to install the latest version of the Unbound DNS service
