No startup Unbound

[Qinn]

Thanks for the reply John, but bind is not installed, it there anyway to find out why during booting pfSense Unbound won't come up?

[johnpoz]

Well look to see what else is using 953 then.

Do a simple sockstat when unbound is not running

[2.4.4-RELEASE][root@sg4860.local.lan]/: sockstat | grep :953
unbound  unbound    49220 27 tcp4   127.0.0.1:953         *:*
[2.4.4-RELEASE][root@sg4860.local.lan]/: 

You can see that unbound is using 953, your error is saying it can not use that port.

[Qinn]

Good idea

With Unbound running, result:

[2.4.4-RELEASE][root@pfSense.localdomain]/root: sockstat | grep :953
unbound  unbound    63945 22 tcp4   127.0.0.1:953         *:*
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:57064
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:1987
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:33822
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:33089
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:64753
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:18454
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:43445

Then a reboot from the console (option 5) below the result in the GUI:

Then:

2.4.4-RELEASE][root@pfSense.localdomain]/root: sockstat | grep :953
[2.4.4-RELEASE][root@pfSense.localdomain]/root:

...but nothing running on 953?

There is something else maybe worth mentioning, it's not every time that Unbound won't start after a reboot, but it's a 50-50 with 3 other services

avahi
pfb_dnsbl
pfb_filter

So the one time Unbound is up and those 3 are down and the other time, it's the other way around?

[johnpoz]

My guess would be something with your pfblocker.. It restarts unbound when it updates - its possible that unbound is not actually stopping and left running..

What is this?

?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:57064

?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:33822
?        ?          ?     ?  tcp4   127.0.0.1:953         127.0.0.1:33089

You can not see the pid of what is bound to 953?

[RonpfS]

When the widget send an unbound-control stats_noreset during an unbound reload, unbound may hang and may need to be kill -9 .

Change the pfblockerNG Widget DNSBL Resolver Query frequency from 5 sec to 60 or 120 sec.

You can also try to enable DNSBL Live Reload Resync so pfblockerNG wont reload unbound.

[Qinn]

[2.4.4-RELEASE][root@pfSense.localdomain]/root: sockstat | grep :953

@johnpoz Your guess is as good as mine , only the first line is unbound?

DNSBL Resolver Query frequency

Thanks RonpfS for stepping in, I can't seem to locate the;

"Change the pfblockerNG Widget DNSBL Resolver Query frequency from 5 sec to 60 or 120 sec."

You've mentioned, of course I will try to enable DNSBL Live Reload Resync and report back.

Click on the Wrench Icon on the pfBlockerNG widget

Thanks, duhhhh, missed out that one, stupid me. I will try that first and if that don't work the
enable DNSBL Live Reload Resync, but it has to wait for tomorrow as some rsync's are running and after that backups are kickin in, so tomorrow I will try and report back!

Thanks again

[Qinn]

@RonpfS setting DNSBL Resolver Query frequency to 60 sec, didn't do much. Next tried the *DNSBL Live Reload Resync, but unfortunately it did not do much either. Still unbound is not running after a reboot...

Anyone any idea's?

Cheers Qinn

Yep.
If you can works a day or two without DNSBL , disable it all together.
Reboot pfSense.
Check.

Doing so will rule out any problems related to DNSBL - or not ....

@qinn said in No startup Unbound:

That is, it should start after a boot. The logs do shows this.
But shortly after that it gets probably restarted, so it stops, and then can't start again.

[Qinn]

@gertjan I stopped and disabled pfb_dnsbl and pfb_filter and rebooted 3 times, on all of them unbound was running and there were no errors in the General Log concerning Unbound and accessing the GUI/Dashboard after reboot now took a few seconds, instead of minutes. It seems very likely that the culprit has found, pfb_dnsbl and pfb_filter and Unbound don't play well , but now to a solution. I hope that @BBcan177 can shed some light on it.

I would concur on this ;) no offense to BBcan177 great work on the package.. But it has become lets call it very complex ;)

@metoo

But the fact is :
pfb_dnsbl import big or can I call them huge - lists.
And when he set them up, it kicks unbound, who starts to parse all these lists using. This needs a lot resources.
I do think a 'correct' setup of pfb_dnsbl would be a good solution.

Yup would concur there as well ;)
