Problem with DNS resolver

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?

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

Jun 7 06:51:28 unbound 17795 [17795:0] notice: init module 0: iterator

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

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.

stephenw10 · Jun 7, 2024, 12:24 PM

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

Good to hear you've sorted it.
Having unbound serve dns records for DHCP leases is known to cause restarts. I think many here disable it and create static leases for those hosts they do want to resolve.
I found explicitly selecting listening interfaces often caused problems with unbound not starting. I set it to 'all', relied on firewall default blocking to prevent access where it wasn't desired, no more unbound start-up issues.
I doubt the upgrade contributed to fixing the issues you were seeing. I reckon it came down solely to the listening interfaces selection!

this should be taken care of by just upgrading pfsense - still not understanding how you had both on the system??

Unoptanio · Jun 8, 2024, 10:55 AM

@johnpoz

Initially I only had version 1.18.0_1 of the unbound DNS.
After updating to version 1.19.1, despite restarting the PC, the two versions were the same. The next day only version 1.19.1 remained.
In the meantime, other PC reboots were made

But isn't it just the log of versions at various times?

@Unoptanio said in Problem with DNS resolver:

After updating to version 1.19.1,

And how did you do that exactly? You updated pfsense, you updated packages on pfsense? You installed it on your own? I can not see a way that both would of been on the system at the same time??

You should never see this

There should only ever be 1 version installed.

Unoptanio · Jun 8, 2024, 10:57 AM

@johnpoz

I haven't updated pfsense.

I only updated the unbound DNS service which strangely was not the latest version

johnpoz · Jun 8, 2024, 11:00 AM

@Unoptanio said in Problem with DNS resolver:

And how did you do that, you ran the package update from cmd line of pfsense - you manually iinstalled a package from outside pfsense repository?

What version of pfsense are you running exactly?

Pretty sure 2.7.2 came with 19.1, let me fire up my VM.. and check..

Unoptanio · Jun 8, 2024, 11:06 AM

@johnpoz

If I updated the unbound DNS service at 1.03.49 PM I think it is normal for it to display the old version which was in operation previously at 1.02.36 PM

try checking the version with the command:

pkg search unbound

with this command you only update the unbound DNS service to the version 1.19.1

 pkg install unbound-1.19.1

with this command check if there are any updated system packages available.

pkg upgrade
