DNS Resolver Status, no data?

KOM

@johnpoz My output is similar to yours.

I suspect I've managed to confuse things by having DNS listed in General Setup - DNS Servers even though I'm using Resolver. There is no reason why it should return results from my AD DCs. The General Setup servers should be completely ignored when running with Resolver.

The time on my pfSense VM is correct.

johnpoz

ignored by who? Sure resolver will ignore them, but not pfsense.

So it shows such entries

That have data in them... Then your infra cache is there and being used... Why your not seeing the info your gui is cosmetic, and or browser problem, etc..

Your on 2.4.4p2?

You learn something new every day. I thought that those DNS were ignored unless Forwarder was in use, or Resolver in forward mode. The info even says that. It doesn't say anything about pfSense using it internally for whatever reason.

Yes, latest version.

@kom said in DNS Resolver Status, no data?:

192.55.83.30 expired, rto 43388736 msec, tA 0 tAAAA 0 tother 0.

Dude that is expired... RTO was it could NEVER talk to it.. All of yours is like that... Looks to me your resolver Not WORKING AT ALL!!

Do the command for some domain you talk to all the time from a client on your network asking pfsense for dns.

Look in your system widget what does it show for dns?

If you have more than loopback there - then yes its possible pfsense could ask any of those NS for dns.

KOM

I had turned off the DNS Servers dealie long ago to save on vertical space in the browser. It's showing me that my AD DCs are my DNS.

At this point, I fully admit that I have no idea what's going on or why. So even when you are using Resolver, if you include any servers in General Settings then it's going to silently forward instead?

johnpoz

NO!! Pfsense (itself) will use what you have listed in the general setup... But if a client asks resolver on pfsense running listening on port 53, then that will either resolve or forward.

But if you do not have loopback listed - then when pfsense needs to check if update, or look for packages, etc. its going to ask those name servers. When you go to the dns lookup menu... its going to ask what is set for in the general tab or gets from dhcp on your wan, etc.

Out of the box pfsense should only ask itself.. which should be the resolver in resolver mode, with dnssec enabled.

Your settings show that your not even doing dnssec.. And from what you showed... Id doubt your resolver can even talk to atleast not the NS for MS, etc.

From a client on your network do a query to pfsense lan IP... Do you get an answer?

Here is 2 example of specifically asking pfsense (resolver) for query of a fqdn

On your client when you do nslookup it comes back with your pfsense as the NS, see how mine says sg4860.local.lan - 192.168.9.253.. That is pfsense lan IP.

See when do a dig, I specifically called out my pfsense lan IP and it answered.

KOM

These DNS settings were mostly inherited form my original 2.1.x installation 4+ years ago. I have no idea what the current default settings are nowadays.

And yes, I can run nslookup, point it to pfsense and resolver some unknown host:

Replaced real hosts/domains with ???

PS C:\Users\KOM> nslookup
Default Server:  ???.???.local
Address:  10.10.0.1

> server 10.10.4.1
Default Server:  wpad.???.???.local
Address:  10.10.4.1

> www.boogers.com
Server:  wpad.???.???.local
Address:  10.10.4.1

Non-authoritative answer:

johnpoz

So you sure dns forwarder is not running and you have a race condition..

So your pfsense is called wpad?

So unbound is specifically bound to 53?

Flush your infra cache, then do some queries direct to pfsense... Then look in your infra_cache you can flush with.
flush_infra all

Do quite a few queries for different things..

You just flushed the cache, so it can answer stuff from its cache... So you need to ask for stuff that is not in the cache

Why would squid be doing the lookups? It's not listening on 53. And I'm not going through the proxy personally (explicit mode, not transparent) so squid is out of the loop.

johnpoz

Why would you be running a proxy if not using it? Makes ZERO sense to run a proxy if not having clients use it.

When browser asks proxy for www.whatever.com - proxy is what looks up www.whatever.com no the client wanting to go to www.whatever.com

Your current infra has bunch of shit blocked with those expired and RTO... Dump its cache, then do some queries direct to pfsense and then look at the infra cache..

We are trying to get some info that unbound is actually working!

You sure you didn't put in a dns redirect and sending your dns queries to pfsense to your AD?

KOM

You're getting off-track here. I run a proxy for my non-admin users. I''m the admin. No proxy for me.

johnpoz

You have shown no info at all that unbound is even working... When you show proxy running... Then I assumed that is what the VAST majority of stuff would be using to get to the net and could explain not seeing large infra cache, etc.

Do my test.. with the dump and explicit queries to pfsense running unbound so we can get some valid info in your infra cache... But RTO of bajillion tells me your not talking to anything..

@jimp, any insight into what's going on here?

jimp

We just show what unbound dumps out. If it's empty, then it's empty in unbound. That could be for any number of reasons, all up to unbound. If you have something like pfBlockerNG and DNSBL active that could contribute to any differences you see. Also keep in mind if you have DHCP registration active for the DNS resolver, unbound will restart for each lease change that triggers a hostname update.

Well that output looks normal... That is your infra cache for that domain, in what would be used to look it up... So you should see the full cache output in the gui then.

As jimp stated all that gui is showing you is the output of the command dump_infra

Yes, I get that. What I don't get is how this list is empty, then 5 minute later it's full, then 5 minutes later it's empty. Does it really flush that frequently?
