Problem with DNS resolver

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??

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?

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.

@johnpoz

I haven't updated pfsense.

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

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..

@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

johnpoz

@Unoptanio yeah the log would show the version from before.. But pretty sure 2.7.2 should of came with 19.1??

Oh my bad, seems 2.7.2 shipped with 18, and pkg upgrade updates it

Mmm, I guess running 'pkg install' somehow left the old version present. Though the output from it looked like it just upgraded it anyway. Which is what I'd expect pkg to do.

In that situation you should really have used pkg upgrade unbound.

@stephenw10
Does the old version need to be uninstalled somehow? or is that okay?

stephenw10

That should be fine. And, just to be clear, I would have expected what you did before to also be fine. pkg shows that it sees that as an upgrade and takes appropriate action.

It shouldn't be possible to have two versions on the same pkg installed.
