DNS Resolver Status, no data?



  • Hello. This is probably just some dumb error on my part, but the Status/DNS Resolver page has never contained any data, either in resolver or forwarder mode. Any ideas? It's 2.4.4-RELEASE-p2 on a Gen 1 Hyper-v VM. DNS seems to operate normally, just no stats.



  • Same here. I had never noticed that before.

    I see some data here

  • This morning I had some data, so I added a couple more servers. Had data for them, too. One of the last things I had done was to remove the Resolver from Service Watchdog while I was messing with DNS Resolver resolving/forwarding and dnsmasq. Stats remained but were lost on a reboot. Stats have not populated since even after various nslookups and web use. Baffled.

    If your not seeing status there, then its not asking anything.. You sure your actually using the resolver - and don't have your clients asking someone else? Did you point pfsense to something other than 127.0.0.1?



  • The only client is li'l old me. Most devices are static IPs (outside DHCP range, but registered in DNS), but a few are DHCP. Statics use FW for DNS. Resolver is enabled in forwarding mode right now, DNS servers are Quad9 and Cloudflare (in General Setup) plus localhost. I earlier saw data on them, since cleared. Assuming this data does not save to disk on reboot? Still no data, been surfing for several hours.



  • OK, I have data now. Why? No idea. Is there some job that has to run?
    Still in forwarder mode, removed, Quad9 servers, data page updated to reflect.
    Changed to resolver mode, immediately had 50-60 lines each in Cache Speed and Cache Stats. Baffled x2. Going to reboot now, assuming this data is volatile?



  • OK, so data is there after reboot (and then some...). Still Resolver mode.
    Around 475 lines in each section (Speed and Stats). Both IPv4, IPv6 addresses... Running only IPv4 here. Sorry if I'm being dense.0_1552502264304_Speed-Stats.txt

    My take on this is you don't actually understand what those stats are.. Or how a resolver works..

    If you flip into forwarder mode it will show you that or multiple if it ever asks multiple stats.. But really means nothing in forwarder mode at all.. Those stats are what resolver uses to determine which NS it should ask for a given domain, etc. be it root or domain.xyz..

    If all you do is forward to A, what would be the point.. If you could forward to A or B then guess could use those stats which to ask A or B..

    There is little need for you to even look into what those stats are unless you were troubleshooting specific sort of issue.



  • I run Resolver. No forwarding. Mine is full of stats now. It wasn't yesterday. Uptime is 48 days.

    So what changed? Why no stats yesterday, and a full page today?


  • LAYER 8 Global Moderator

    I have no idea.. You have provided ZERO info on your setup..

    Here resolver mode.., changed to forward mode google, stats

    Its not freaking rocket science here people
    0_1552503156112_resolverforvsresv.png

    Your typical user is going to have ZERO understanding of what those stats even mean to be honest ;) Anyone that would actually want/need them would be able to pull them from the cmd line anyway..

    Now back to resolver mode because forwarding = uuuuggghhhh!



  • That's entirely possible. But I'm in Resolver mode now. All I ever saw in Forwarder mode was data for the servers setup in General, which figures. Why should it ask anybody else? A Resolver goes straight to the roots. But until recently I saw no data at all in either mode. Doesn't resolver use that cache data to know which root server will give it the fastest reply? Without the cache, what happens? Dud DNS?


  • LAYER 8 Global Moderator

    It uses the roots to do the first lookups.. Picks 1 at random... They all that the same info... Your just asking 1 of the root servers for the NS of com, or net or edu or whatever you asking.

    It then keeps a cache at how fast these different NS it talks to respond.. If it finds out that hey root A answers faster than C... Its going to first try A, before it asks C for anything, etc. etc.

    Your typical user has zero use for this info.. Al he wants to know is hey I ask for www.google.com and got back an IP..

    You would really only need to look at this info when troubleshooting the most odd sorts of issues.. Other than just curiosity sake - or overall health to see if your seeing any sort of timeouts and what sort of response times your getting, etc.

    There back to showing stats for normal resolver stuff the second after changing back

    0_1552503703539_backtores.png

    And to be honest would prob not ever look at it in this sort of output.. Its too much info... Your prob going to ask for the infra cache info for the specific domain you are having issues resolving from, etc..

    Why they even put this on a menu item - is nothing more than eye candy if you ask me.



  • And now my list is back to No Data...

    I don't think details of my setup have anything to do with a stats page being filled by a service that is running.

    And now I have some limited data there. All this in the span of 5 minutes. This makes no sense unless this page has a short time threshold before it wipes everything.


  • LAYER 8 Global Moderator

    You have something wrong if your not seeing data and actually using the resolver... After it does one query.. It will store that info.

    Is your resolving actual working? what does your resolver log show?

    For all we know your resolver is running but your not actually asking it anything.

    Maybe you got a browser cache issue that is not showing the info should be showing - do the query from the cmd line of pfsense. One sec and give an example.

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

    And now I have some limited data there. All this in the span of 5 minutes. This makes no sense unless this page has a short time threshold before it wipes everything.

    How often is unbound restarting on your system? Check the logs.


  • LAYER 8 Global Moderator

    Here is from cmd line

    0_1552504214462_infracachedump.png

    All the web gui does it take the output of that and present it..

    No unbound is not going to wipe that data on any sort of schedule.. This the data it uses to know which NS are best to talk to, etc.

    Take a look to see how many actual queries have happened since unbound restarted

    total.num.queries=287
    total.num.queries_ip_ratelimited=0
    total.num.cachehits=218
    total.num.cachemiss=69

    Use
    unbound-control -c /var/unbound/unbound.conf stats_noreset

    Look through for total, etc. How many queries happened, etc. since unbound restarted. If 0 then no nothing going to be in the stats for the infa.



  • You have something wrong if your not seeing data and actually using the resolver... After it does one query.. It will store that info.

    I think pfSense might be doing something wrong. I am definitely using Resolver. I can resolve via Diagnostics - DNS Lookup. The stats page seems to be randomly full or empty.

    Resolver log shows:

    Jan 23 21:36:20 	unbound 	78590:0 	info: start of service (unbound 1.8.1).
    Jan 23 21:36:20 	unbound 	78590:0 	notice: init module 0: iterator
    

    and those are the latest updates.

    Interestingly, a manual nslookup shows the answering DNS server to be one of my AD DCs. Back when I first installed pfSense (2.1.x), I had it configured for DNS Forwarder, and I put my AD DNS into General Settings - DNS Servers. Later on, I disabled Forwarder and ran Resolver instead. Resolver is definitely NOT in forwarder mode. And yet it's still sending request to my DC.


  • LAYER 8 Global Moderator

    If your an AD shop your clients should directly be asking your AD dns anyway... Have it forward to pfsense if you want.. But might as well just have your AD resolve, etc.

    Do the command I asked before - lets see how many queries have been asked of unbound.



  • unbound-control -c /var/unbound/unbound.conf dump_infra

    returns blank, and my stats page is back to No Data. So bizarre.


  • LAYER 8 Global Moderator

    and lets see this

    [2.4.4-RELEASE][admin@sg4860.local.lan]/root: unbound-control -c /var/unbound/unbound.conf stats_noreset | grep total.num
    total.num.queries=336

    total.num.cachemiss=85
    total.num.prefetch=0
    total.num.zero_ttl=0
    total.num.recursivereplies=85
    [2.4.4-RELEASE][admin@sg4860.local.lan]/root: 
    

    How many queries so mine went from 200 something to 336 in the couple of minutes.



  • total.num.queries=7233
    total.num.queries_ip_ratelimited=0
    total.num.cachehits=6981
    total.num.cachemiss=252
    total.num.prefetch=4892
    total.num.zero_ttl=4748
    total.num.recursivereplies=252
    

    and Stats is still blank.



  • @kom No idea if this means anything, but I had a 10 minute time drift between my VM and Real Life. Looks like NTP to pool.ntp.org wasn't quite working for me. Corrected and now seems to be working. Coincidence?


  • LAYER 8 Global Moderator

    Lets see whats in the infra cache.. ask unbound who it would ask for specific domain... For example just did microsoft.

  • @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.


  • LAYER 8 Global Moderator

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

    So it shows such entries

    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.

    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?
    0_1552506529918_whopsensewillaskfordns.png

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



  • 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.

    0_1552506880955_DNS_Resolver.png

    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?


  • LAYER 8 Global Moderator

    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

    0_1552507491808_dnsqueryexample.png

    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.



  • 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:

    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.


  • LAYER 8 Global Moderator

    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?



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


  • LAYER 8 Global Moderator

    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..
