Frequent unbound restarts
-
Since there is a simple way to fix this extremely frustrating problem, is there any progress on it?
Like, please Netgate, one of the most useful features is not working.
-
What is not working ?
This thread highlights two possible reasons why unbound is restarting.
Because it should restart to take changes in account.@sotirone said in Frequent unbound restarts:

Don't get it.
What progress is needed if a simple fix already exists ?
An even more simple fix ?You agree with me that their will never be a situation that a program/service/ functionality/etc will work for every type of scenario ?

@Gertjan Our problem is mostly because of the dhcpleases sending a HUP request and triggering the unbound reload.
So, changing the code to use unbound-control instead of sending a HUP request is the easy fix, no?
-
I would qualify this as "easy" : Remove the check from here :
Changing https://github.com/pfsense/FreeBSD-ports/blob/9e4bb79caf876017a31a09176947b88d69588f1b/sysutils/dhcpleases/files/dhcpleases.c
is less forward.
Because using unbound-control to administer unbound's internal structures and records is less documented / less known (my opinion).
One minor glitch and the entire local DNS goes down ... or contains wrong info which is even worse.This small program, called dhcpleases,isa process that keeps running as a daemon, wakes up when the dhcp.leases file changes, as this would happen if the DHCP server 'changes' something, like when a new lease is attributed - or a lease is renewed. Note that the latter case is not actually changing the IP thus the required DNS info.
All active leases are then formatted for the system /etc/hosts file, and copied over to that file. When done, unbound is signalled = HUPped. Upon receiving of this signal, unbound .... it restarts it self.
If dhcpleases was using unbound-control, it could transmit the unbound process the 'new' or 'renewed' host name and IP address from the lease info, one by one ( ! ) .
I'm wondering :
When we have a big network, and many, like 48 devices that are hooked up to a 48 ports switch, and this switch powers down and up, 48 PC's will receive an "interface UP" signal. These 48 PC's will fire a DHCP-client request to the DHCP server, pfSense.
48 renewed (== updated) leases will get written, actually : updated, to /var/dhcpd/var/db/dhcp.leases file in a rapid manor.Parsing the /var/dhcpd/var/db/dhcp.leases and adding the distilled content to /etc/hosts file is one thing.
Firing 'unbound-control', a big process by itself, to transmit just one changed 'host name' + IP address, multiplied by 48 because 48 PC are renewing, is another thing.Note : I activated "DHCP Registration" in the Unbound config settings : it look likes dhcpleases contains a minor bug : the DHCP info is added 3 (identical) times :

What is the status on this? I see a lot of ubound restarts, I can't believe this issue has not been fixed since 4 years. Is it that fix is impossible, too hard, or developers are unable to recognize this problem?
-
@lutel Still broken as you can see.
It is actually working in OpnSense, which was previously a pfSense fork but now refactored and based on HardenedBSD rather than FreeBSD.
-
I could present my :
Unbound just restart again.
Or was it because I just upgraded, at 07h00 am, the package pfBlockerNG-devel to the latest ...14 ?
Something I do nearly every day as fine polishing is happening after pfSense 2.5.0 came out.If not, I guess my 'unbound' restarts .... one or twice a week, or less.
unbound restarts can be explained. Up to you to chose if it should happen. This forum is filled up with the why/when/what/what else.So, we have the same code ... what differs is the set up (the admin).
Should I details mine ? -
@lutel I detailed how to fix it more than a year ago. The IPv6 story also hasn't been addressed for years. I think it's time to accept that this product is dying and move onto products that are still being actively improved.
-
@jasonarlouser Your excellent write-up helped me understand this issue -- thank you. I was seeing the same frequent restarts w/ dhcp computer names and long restart times due to pfBlockerNG.
I recently switched (back) to OpnSense, partly for this reason (and partly due to the widening community/pro version split), and have been happy to see that the OpnSense Unbound package now has rudimentary DNSBL baked-in. It doesn't sinkhole to a specific IP for stats-gathering like pfBlockerNG, but it certainly blocks well enough. That, plus zone reloads with unbound-control have (so far) led to a much better experience.

Sorry to hijack this topic but I want to make sure I'm having the same issue:
I have a pihole set as the primary DNS on the DHCP lease. Pihole sends all DNS requests to Pfsense on the same subnet.
Originaly I had pfsense set to forward to clouflare (1.1.1.1) but now I unchecked forwarder mode (see screenshot below)
The dns requests were much faster and website browsing feels faster (so that is positive). But the down side is that one or two times daily (usually in the midnight and when waking up in the morning we have no internet). This is purely a dns issue because I can browse to external IP's (for example 1.1.1.1).
When checking the logs I see:

What pfSense version ?

then, as mentioned, the IP and host name are registered into the DNS.
To do that, the resolver, unbound, has be to restarted.Consider using static MAC DHCP leases - and make the lease time as big as possible.
Or disable those option.@audiaddict said in Frequent unbound restarts:

This is on the other side : WAN : Your DHCP client - remember : it asks a IP from an upstream (ISP ? ) router really lasts 1 minute or 60 seconds ?
Why ?? -
Version 2.5.0-RELEASE (amd64)
built on Tue Feb 16 08:56:29 EST 2021
FreeBSD 12.2-STABLENo idea on the WAN refresh.. this is a Ziggo (vodafone) ISP modem that I have no control over really. It's set to bridge.
Can you confirm by disabling the registering of DNS entries under DNS resolver - this should not cause these DNSresolver restarts?
Also any idea's why I'm getting double DHCP duplicates? See last logs.
I'm using static DHCP entries with mac address under DHCP server.

Then you would be sending them some words like
Geachte support, Is het mogelijk om de lease van iet wat meer dan 60 seconden te krijgen ?

After answering the same question, some 1000+ forum messages, from the last 2 years or so.
Yes, I can confirm.
This was the issue with 2.4.5-p1.How 2.5.0 works these days : dono.
I can see it's still HUPped. Maybe its not restarting anymore, but just re reading the config files, and among them, the modified /etc/hosts file that contains (updated) DHCP client IP hostname information.Cn you imagine what happens if you had a client device that was asking for a new lease every 30 seconds ??
It would totally explode unbound ..... as ir would have to handle the HUP alll the time.Believe me :
Make static DHCP MAC leases for your devices that need a fixed IP - host name relation.
Un check the option.
Done.I have de activated that option several years ago.
unbound is rock solid.edit :
Mar 3 08:43:58 Porsche dhclient[10769]: Cannot open or create pidfile: No such file or directoryisn't good.

@gertjan But the issue is this is mis-implemented. No HUP needs to be sent here and if so all that needs to happen is use the command specified above to reload the local zone (the only one which could possibly be affected by DHCP leases). I can't think of a single other product anywhere that has this problem because every other vendor knows how to deal with DHCP leases adding DNS names.

@jasonarlouser said in Frequent unbound restarts:
No HUP needs to be sent here and if so ....
Please check the "vendors" instruction : the ones who make and maintain unbound.
The question is : when is the local /etc/hosts file re read in ?
Or, you might bask : is there another way to communicate a running unbound process the presence of a new local host + IP ? (answer : yes, there is ..... )Back, in the dark ages, the manual was : look up in the C source code why HUP was needed, and what it does when one is received, etc.
It's time I make this tour again, see how the more recent unbound version behave.
But I'm registering unknown device's DHCP leases any more in my DNS. All the devices I need to contact have chosen host names, and chosen IP's addresses.
Same thing for IPv6.
So, it became a non issue for me.Anyway, the unbound+DHCP leases thing is an ongoing discussion for a couple of years now.
In the past of pfSense :
dnsmasq was used before, but considered to light - and has no DNSSEC support.
So, unbound came up ... and was choosen.
"bind" might be used, but was often left out as to - far to - big. -

@brad-edmondson said in Frequent unbound restarts:
@lutel Still broken as you can see.
It is actually working in OpnSense, which was previously a pfSense fork but now refactored and based on HardenedBSD rather than FreeBSD.
This aged well.

@jwt Sorry, I don't follow.
Are you referencing the wireguard fiasco? Or was there some other news that put this into an updated context? An unbound regression in OpnSense 21.1.5?
On WireGuard, AFAIK OpnSense has a userspace daemon similar to what pfSense has offered for a while, not the in-kernel implementation that was apparently borked and then yanked.
EDIT:
Are you referring to this OpnSense forum post? I think that's isolated as that user had other problems when upgrading w/ unsupported packages (not to say unbound is unsupported, just that theirs seems like a complicated configuration).To be fair I did suffer from some constant unbound restarts on my own OpnSense box yesterday, but I haven't updated that machine from 21.1.4 to 21.1.5 yet so I'm 99% sure that was down to my toggling the ramdisk option for /var and losing unbound data at reboot. (I had read the option as /var/log ramdisk, which I assumed would have no ill effects. The /var option not so much since it encompasses so much more.)

Is there any news on this?

@sotirone still broken.
