Request to pfSense.localdomain timed-out
-
Do you have your ACLs setup? Did you mess with those?
To me from that permissions denied statement in the log I think you have your accesslist messed up. And not allowing anyone to query the resolver.
-
nothing is messed up sir. i did nothing just started this morning when i tried to access some websites like redmondpie fb etc.
don't know what happend
-
well without accesslist not going to be able to use resolver.
-
what "without accesslist not going to be able to use resolver"
im using internet without any modification since one month. i didn't added or removed anything from access list.

Sir KOM,
here if i put 8.8.8.8 on machine manually FB open flawlessly but on 192.168.1.1 pfsense ip nothing server not found. only youtube working fine fine
-
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.

You can see it refusing queries from my local network.
Do you have this checked or unchecked?
-
For me resolver is unable to resolve at least these two domans:
github.com
twitter.com -
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.

only youtube is working properly…. How to correct my dns resolver if it get corrupted
-
I plugged Linksys RV042 everything working fine. just pfSense having problem unbound DNS resolving…
Any hope for broken Unbound DNS resolver or fresh install again?? :-\
-
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

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.
-
U need to query pfsense directly with ur dig command because where is linux actualy sending that quer? U are doing query to itself
-
i dont know why 127.0.0.1 unbound unable to resolve domain names. only youtube working. Do i need to update some kind of cache of unbound DNS?
