          Yes, I understood that the first time you said it.  You are either having a DNS problem with your upstream or your configuration is somehow broken.  Since a couple of people are complaining about DNS today, I thought it might be related to the DDoS of DynDNS.

            Yeah there is a major ddos to a major dns provider going on right now.  If they are hosting the authoritative servers for domains your interested in looking up then you going to have a problem.

            Looking up pfsense own name has nothing to do with outside dns though.  You have to have a access list to be able to query resolver.  I you can not query pfsense own name, then resolver not running, your not allowed because of accesslist or you have connectivity issue or something broke in the resolver.

            I upped the logging level in my resolver.

                yeah those are listed as two of the domains that are hosted there..

                github.com.            172800  IN      NS      ns1.p16.dynect.net.
                github.com.            172800  IN      NS      ns3.p16.dynect.net.
                github.com.            172800  IN      NS      ns2.p16.dynect.net.
                github.com.            172800  IN      NS      ns4.p16.dynect.net.

                twitter.com.            172800  IN      NS      ns1.p34.dynect.net.
                twitter.com.            172800  IN      NS      ns2.p34.dynect.net.
                twitter.com.            172800  IN      NS      ns3.p34.dynect.net.
                twitter.com.            172800  IN      NS      ns4.p34.dynect.net.

                dynect.net is what is under ddos.

                      Yet again. Nothing todo with Unbound per se. Just try some different upstream DNS servers to test. I had problems a few days ago, too and adding e.g. an opendns and another local free dns server in addition to 8.8.8.8 helped solving it as even the Google DNS couldn't resolve twitter and github anymore. A few others had other cache timings etc. so could still resolve them. That helped.

                      Also restart/refresh unbound so it resolves the domains again and doesn't use negative caching against you.
                      Use "ipconfig /flushdns" as you're using windows. That caches negative DNS, too.
                      Not everything is simply a pfSense problem ;)

                          Ya think maybe your pfblocker dns might have something to do it it ;)

                          lets go over this again..  Can you query pfsense own name from something on your network?

                          example

                          dig pfsense.local.lan

                                lubuntu@lubuntu:~$ nslookup pfsense.localdomain
Server:		127.0.1.1
Address:	127.0.1.1#53

Name:	pfsense.localdomain
Address: 192.168.2.1

                                Small correction pfsense.localdomain not pfsense.local.lan. This  is all what i get dig output, using same configuration since 16days no reboot. suddenly stopped resolving hostnames,  somehow only youtube working fine without any problem.

                                should i need to specify dns ip also - System/General Setup/ DNS Server setting

                                also using some packages like SNORT, pfblockerNG, squid proxy transparent mode. ClamAV.

                                        any idea what i do now, because 127.0.0.1 not resolving domains…..... DNS look also keep searching but nothing

                                        NOTE:-- tested this - when i do DNS Query Forwarding - Enabled and put google DNS 8.8.8.8 in System/General setup eveything works normal. But before that i use to keep uncheck DNS Query and no DNS in System/General everything just works fine....

                                          dude so when you query the pfsense directly??

                                          dig @pfsenseIP pfsense.localdomainname.tld

                                          does that respond or not?

                                          On pfsense using the resolver and pointing to itself, can it resolve other domains?

                                          Your problem is your linux is asking some service running local, that does what?  does it forward to what?

                                          Its possible pfsense resolver is having an issue talking to roots and the authoritative ns.  But it should be able to resolve its own name when asked by itself or other clients

                                          Its also possible you just don't have an Accesslist that allows your client to even query pfsense for anything that the resolver can resolve either your own local names or host overrides or outside.
