      @Derelict:

      Try this at a shell prompt:

      rm /var/log/resolver.log

      ls -l /var/log

      Get the size of the other logs default is 511488

      clog -i -s 511488 /var/log/resolver.log

      chmod 600 /var/log/resolver.log

      bounce unbound

      Thanks! That did the trick! I had assumed that they were just ordinary text files but that makes a lot more sense haha.

      Strangely enough….. now my DNS query return is different AND www.aviationweather.gov loads immediately with no problems...  :o

      The only thing I did different than the last post is accidentally screw up my resolver.log and then get it back up with Derelicts instruction.

      Why would a log have any effect at all? Assuming it must have been something else but I can't imagine what? I had already restarted Unbound & rebooted the system a couple of times so that wasn't new.

      dig is different now too:

        It wasn't the log. It is probably just resolving for you now.

          May never know what what going on, since you can not seem to grasp how to do a directed query.. In all the nonsense you posted.. Not one of them was a query to one of the NS authoritative for that domain…

          Just like you query @yourpfsenseIP

          Do you query direct to one of their NS.. as I did in my example..  And why and the F are you doing a query for "www.aviation.gov"

          Glad its working for you - since troubleshooting to where the problem actual is with what your posting would be fruitless..

            Eh, yeah. I have literally zero background in IT or anything computer or networking related. If I haven't read it for fun or been told something, I don't know it. So it doesn't surprise me I got it wrong, I do apologize though, I appreciate that you've taken your time out to help me.

            I was querying aviationweather.gov because it's the only site that I've ever had trouble with, and the reason I started this thread.
            EDIT: reading back I see you mean why i mistyped "aviation.gov" instead of "aviationweather.gov" and posted that output, that was totally unintentional, I was tired!

            I thought that the following was the Name Server for aviationweather.gov (which is what I assumed you meant by NS?)since it was listed in the return for aviationweather.gov, and start with "ns".

            bash@DESKTOP:~$ dig ns-e.noaa.gov
            

            I don't even know what you mean by this?

            Just like you query @yourpfsenseIP

            I think the only IP i queried was:

            bash@DESKTOP:~$ dig 140.90.33.237
            

            Network information
            IP address 140.90.33.237
            Reverse DNS (PTR record) ns-e.noaa.gov

            Is that what you mean?

            I'd be happy to learn if you're willing to educate me, but I also totally understand if you're no longer interested.
            Either way, thank you for taking your time and I apologize for the frustration.

              "dig 140.90.33.237"

              All that did was query you default dns for that IP..

              Thee are 3 NS listed for this domain.. If you want to ask them directly then you would use the @

              So

              dig @140.90.33.237 then what you want to ask it..

              so

              dig @140.90.33.237 www.aviationweather.gov

              dig @140.90.33.237 www.aviationweather.gov

                OK, thank you! It is once again not working for me.

                I also attached the resolver log.

                  Well that dig command says you could not reach that NS

                  "connection timed out; no servers could be reached"

                  So its either down, or your isp is having issues talking to that network.  I do not show any problems talking to any of them.. Try one of the 2 others ones..

                  ns-e.noaa.gov.          86400  IN      A      140.90.33.237
                  ns-mw.noaa.gov.        86400  IN      A      140.172.17.237
                  ns-nw.noaa.gov.        86400  IN      A      161.55.32.2

                  dig @140.90.33.237 www.aviationweather.gov +short
                  aviationweather.ncep.noaa.gov.
                  aviationweather.cp.ncep.noaa.gov.
                  140.90.101.207

                  dig @140.172.17.237 www.aviationweather.gov +short
                  aviationweather.ncep.noaa.gov.
                  aviationweather.cp.ncep.noaa.gov.
                  140.90.101.207

                  dig @161.55.32.2 www.aviationweather.gov +short
                  aviationweather.ncep.noaa.gov.
                  aviationweather.cp.ncep.noaa.gov.
                  140.90.101.207

                  Simple solution would be prob to just put in a host override for www.aviationweather.gov to point to the IP 140.90.101.207, while they have a really short ttl 120 seconds, and then 300 seconds for that cname the IP has not changed since this thread has started 140.90.101.207..

                  edit:  BTW I don't see anything in that log for aviationweather.gov

                  If you queried it directly unbound would not have any knowledge of that or log that..

                      If you can not get to those servers then yeah your not going to be able to resolve records they are authoritative for.  And since the ttl they have on them are very short..  This problem is going to come up all the time..

                      Can you ping them??

                          well that is a bad test - I should of tried pinging them first before suggesting that.. they don't seem to answer ping..  But not having any problems doing dns queries to them..

                            Weird, it's in and out for me. I also have no issues with them when not using the resolver. I'll do the override and deal with it I suppose.

                            Thank you again for taking your time to help me out!

                              But you can plainly see using proper DNS diagnostic tools like dig that the problem is not in the resolver, but in the ability to reach their authoritative servers.

                              Maybe their name servers are overloaded because of the short-ass TTLs they're using.

                              It used to be bad form to use such short TTLs.

                              Still is, IMHO, for most anything but DDNS (which could be debated is no solution at all) and in advance of known, pending changes.

                                I would think such a site gets quite a bit of traffic.. Using 120 second ttl has got to just be crazy for the amount dns queries their servers are taking.. which then points to another cname - that has a ttl of 300.. Really freaking stupid if you ask me!!

                                And to top it all off that ending IP has not changed..

                                And then to top of that one of their IPv6 is just down..

                                Whoever is running their dns seems to be a sleep at the wheel..

                                  I was assuming that it worked when I don't use the resolver because public DNS has the IP cached already? Seems like doing a host override is basically doing the same thing until their IP changes?

                                  Thanks, I will send them a message!

                                    Yes using the forwarder would have you just get what they have cached..  But its going to have to be asking them ever 120 seconds as well ;)

                                    Your going to get something shorter as your answer because it will come from their cache..  So see when I ask googledns the ttls on the records are something shorter then what the authoritative servers set them too.  While if I ask one of the authoritative servers I get the full ttl to cache.

                                    I don't see that site changing.. might as well just put in a override for it vs some domain override to ask google or opendns.. Since your just going to be asking them over and over again just like your doing with the authoritative servers your having problem talking too.  While if you put in an override you can set the ttl to whatever you want so that clients just ask pfsense very X seconds..

                                    I think the default host overrides are 3600 seconds.  But you can always put in whatever ttl you want if you use the custome/advanced box to put in the record.

                                      Very short TTLs are used for certain sites like akamai where they are used for additional load balancing and redundancy. On this type of site it's lunacy though, it's only going to bog down the authoritative servers that are most likely not very beefy this being a US government site.

                                        Sure a CDN with thousands of servers and sites that point to multiple IPs in a round robin, etc. etc.  They have a network to support such short ttls..

                                          Thanks, I put in the override and all is well!

                                          I am having issues accessing www.aviationweather.gov and I believe that it is due to your DNS servers setup.
                                          Specifically your DNS servers TTL is abnormally short, resulting in for more queries to your server than are necessary.
                                          As a result my queries often time out and I cannot access aviationweather.gov to check weather for my flights.
                                          You can see discussion and network testing of your DNS servers here: https://forum.pfsense.org/index.php?topic=127400.0
                                          Please forward this to the relevant people and ask them to adjust your DNS server settings to be more efficient and reliable, thank you!/ncep.awcweb@noaa.gov

                                            well just some idiot passing it on.. The developers prob have zero to do with the dns most likely.. And its a given in your email to them you were using the www ;)

                                            But hopefully it will work up the chain.
