Weirdester [sorry] DNS issue, appending local domain to querries inconsistently
-
Thanks for the reply, I tried the DNS flushing and it didn't work, and the linked post is about hostoverides which I am not using and I can't find anything there that seems to help, maybe I am too obtuse. With an external DNS as first goto in windows, everything works fine, but if the pfsense lan address is used, I get the anomalous behavior.
I installed firefox on one PC-was using palemoon, and it could not find freebsd.org as its first link tried, and it can load youtube pages but many videos error out. And, over on the DMZ, in a linux system, trying to browse to www.freebsd.org gives me my home webserver, also on that machine, but an nslookup without a period at the end gives the expected IP-8.8.178.110. Trying that in the browser, http://8.8.178.110, and it immediately switches to 'www.freebsd.org' in the address bar and gives me my home server again???????
I've tried with and without the rebinding attack protection, I've searched for anything causing these pages to be blocked and that isn't happening, and shouldn't with the default rules. I've flushed the DNS cache in windows numerous times on different machines, no change. Doing a DNS lookup on pfsense webconfigurator gives back 'wfe0.ysv.freebsd.org.', plugging that into the box, less the period on the end, and I get the 8.8.178.110 that is its IP address, is that normal? Many of the DNS queries I looked at with wireshark had such returns, I think they are the nameservers of the sites getting queried. Also, the 127.0.0.1 entry in the DNS diagnostic in pfsense webconfigurator is giving no response, which it had been returning responses earlier, I don't know what I did to make that happen, but when pfsense is first installed, it usually didn't give an answer, but then it just started up after ??????????.
There is probably some switch somewhere I've very stupidly set but I sure can't find out what is going wrong. Why are only certain IPs not working, some pages don't render right because only part of the contents come from url's that are getting screwed up To sum it up succinctly, aaaaarrrrrggggghhhhhhh. I am utterly flummoxed, nonplussed and feeling thoroughly minused.

Ok for starters where does pfsense get its dns, if your asking it? Your isp? open, googledns what?
Its not behind another router and asking is it?
Second, windows can cache dns and so does your browser. I know how to turn it off in firefox, but would have to look up how to do it in others if possible. Turn off in ff, about:config network.dnsCacheExpiration set to 0
Lets just get some pure clean facts so we know what your getting in your queries for starters.
Fire up your fav analyzer - I like wireshark because it runs on windows, linux, etc. very easy to use. Fire it up first thing before you go trying to get anywhere. Then using your browser trying to go somewhere and we will see exactly what you asked for, and exactly what you go back.
You can run tcpdump, diag capture on your wan interface as the same time and we can see if pfsense went and asked for what, and from who and what got sent back, etc..
So you mention this www.freebsd.org a couple of times. lets use that for my example test since you want to get there and are having issues.
I don't believe I have been there since i have started my machine or my browser so I fire up wireshark on my box, and running capture on pfsense.
So looks like pfblocker is blocking that to me!! So in my wiresharks you can see I send out asking for www.freebsd.org and get back the
And here is what I see happen.
In the one capture you see my browser send out query and get back the correct cname and IP.. And you see in other capture that pfsense as designed send it to every dns configured, both my isp at ipv4 and ipv6 dns. I have blocked out my ips in both sniffs for privacy concerns.
Now I had the same issue site would not load, but clearly its getting back the right IP. I even queried the owning servers after looked them up via whois
Name Server:NS1.ISC-SNS.NET
Name Server:NS2.ISC-SNS.COM
Name Server:NS3.ISC-SNS.INFOdig @NS1.ISC-SNS.NET www.freebsd.org +short
wfe0.ysv.freebsd.org.
8.8.178.110All come back with that same cname and IP.. but seems you must be using same lists as I am using from iblock with pfblocker, notice the firewall rules using pfblock aliases and popup screenshot that 8.8.178.0/24 is blocked!
Which is in one of the lists I put in my spyware list – wtf they have against freebsd.org? I don't think that freebsd is serving up any spyware. And if you lookup that network AS10310 Yahoo-prod Yahoo, Inc. production AS, I doubt its serving up spyware -- so someone made a mistake on their list I think.
So it seems you have a blocking problem as you first thought and not a dns issue.
edit: So disable the rules that were using the lists from iblock with pfblocker - and shazam freebsd.org pops right up in the browser.. see added image

Thank you for johnpoz for all that effort.
pfsense is connected directly to a timewarner cablemodem
My DNSs:
127.0.0.1
70.85.0.141
129.115.102.150
67.214.64.27
199.192.200.41I tried the DNScache setting in browser and it did not help, I didn't think it would because a new firefox install exhibited this anomalous behavior on its first URL attemp, which was www.freebsd.org.
Early on, I did have freebsd getting blocked, that was an early confounding/confusing element in the really overcrowded mix of issues, it is blocked in the iblockads list, with 'Maven Networks:8.8.178.0-8.8.178.255' listing, don't know anything about that, just deleted that line. Since I can browse to that site on the PCs I set 8.8.8.8 as preferred DNS, and can browse there on some of the PCs with pfsense as primary some of the time also, it definitely isn't getting blocked. ALL systems using pfsense as first DNS all exhibit anomalies, they are inconsistent and intermittent.
This install is the 3rd try, the first two lasted a few days and I couldn't get certain things right in them, so this is third, neither had this issue, and this install was working for a few days before I tried to install blocker using the host file from http://winhelp2002.mvps.org/hosts.htm, designed to block sites using the hosts file in windows, it is a long list of sites all directed to 127.0.0.1 in order to block them. pfblocker didn't seem able to parse the file since it wasn't blocking the sites, so I went with some of the iblock lists. I keep bringing this up because of the timing, the problem started after I tried that hosts file in pfblocker, which had been removed and substituted with the iblock lists, and I've turned blocker off, and none of this stopped this behavior.
So, the PC I'm on right now and 8.8.8.8 set for DNS, so it was working fine, I just set it back to 10.0.0.1-the lan address for pfsense. From a windows command line I got this[173.174.xx.xx is my external IP]:

And the browser shows "Pale Moon can't find the server at www.freebsd.org."
I just did another flush and this time freebsd.org comes up in the browser!!!! arrrggghhh^googol,
But, trying another high-failure rate www.ip-adress.com, and that fails. Looking at the wireshark captured data, the DNS queries for the successful and the failed www.freebsd.org are the same:
www.freebsd.org: type A, class INThis is flushing DNS and what the command line sees:
C:\Windows\System32>ipconfig /flushdns Windows IP Configuration Successfully flushed the DNS Resolver Cache. C:\Windows\System32>nslookup www.ip-adress.com Server: pfsense.MYDOMAIN.org Address: 10.0.0.1 Non-authoritative answer: Name: www.ip-adress.com.MYDOMAIN.org Address: 173.174.xx.xx C:\Windows\System32>nslookup www.ip-adress.com.

This behavior seems perverse, it changed while I writing this post, the browser has:
network.dnsCacheExpiration;0
I flushed the DNS before both the successful and unsuccessful freebsd attempt. NOW, I reset-to checked-the 'append parent suffixes of the primary DNS suffix' in the advanced dns config settings for the NIC/connection, I did this because I hadn't seen any queries with the mydomain appended as I had seen before, this is within 10 minutes of the above 'not-working' to 'working' on freebsd, and now it again couldn't get to freebsd, AND it could find ip-adress, another random sitcheroo. Of note, when I tried freebsd addresses, there was NO query to pfsense!!!!!??????!!!!!.I want to go home, [but [i]leave the toys]. There is some kind of caching/time-to-live/DNS resolving interaction going on with this intermittent thingie is the only thing I can remotely figure, and it is some setting somewhere that got mis-set somehow, but it has to be in pfsense since everyone started going crazy at the same time [or is this mistaken somehow?]. The lack of response on a DNS query in the webconfigurator for 127.0.0.1 when it had been working earlier, could that mean something significant? Could this be a NIC hardware issue, the symptoms don't seem like that is likely??? Why do all youtube pages load but many to most of the videos don't? I've been on the verge of just re-doing the install, it isn't that big of a deal, but I really wanted to figure this out. So I will wait a couple of days, see if anyone sees where I've po'ed the network gods, and if not, reinstall.
To all who've bothered to look through all this, thanks!

Ok I don't have time right at this minute to read all through that info - but this jumps out at me
" I just set it back to 10.0.0.1-the lan address for pfsense. From a windows command line I got this[173.174.xx.xx is my external IP]:"
C:\Windows\System32>nslookup www.freebsd.org
Server: pfsense.MYDOMAIN.org
Address: 10.0.0.1Non-authoritative answer:
Name: www.freebsd.org.MYDOMAIN.org
Address: 173.174.xx.xxWhat is this MYDOMAIN.org thing?? Are you changing that, or is really mydomain.org? Since its all CAPS what are you changing this out for?
And do you see how I did a sniff, where is your sniff. I want to see exactly what your doing a query for and to where?
Those IPs you list don't seem like your ISP dns to me
dig -x 70.85.0.141 +short
8d.0.5546.static.theplanet.com.dig -x 129.115.102.150 +short
juliet.it.utsa.edu.dig -x 67.214.64.27 +short
dns1.telwestonline.comdig -x 199.192.200.41 +short
ct41.7wei.com.Those are not the dns servers for timewarner - where did you come up with using those?
And your config still shows the aliases for pfblocker and using the ad list that blocks freebsd.org network.
Lets see the sniff of your query, I really don't think your local domain is MYDOMAIN.org is it? And if it is - you do understand that is a public domain!! and I doubt you own it

But this is telling me it was cached at the server for that fqdn with your suffix on the end
Non-authoritative answer:
Name: www.freebsd.org.MYDOMAIN.org
Address: 173.174.xx.xxNot sure what this means..
nslookup www.freebsd.org.
Server: pfsense.MYDOMAIN.org
Address: 10.0.0.1Name: www.freebsd.org
Served by:- L.ROOT-SERVERS.NET
- M.ROOT-SERVERS.NET
- A.ROOT-SERVERS.NET
But clearly the box does not have a clue about that request. If it just throws back roots, but since it did not throw back a nxdomain, I would assume its telling you it needs to be forwarded??
Ad some point did you try and run local dns on pfsense? unbound? Or tiny? And I don't understand why your using those odd ball dns for your forwarders? Why not your provider? Or some more well known public dns, 4.3.3.3, 4.2.2.2
How about using debug on your nslookup, your going to see that windows is going to ask with its suffix attached
So you got something going on with that suffix your using? Lets see what is going on exactly, where is the sniff of the traffic from your client to pfsense, and then what pfsense sends out and gets back. Or what it answers back because it has that record.

I really appreciate you taking so much time trying to help. I blanked out the particulars of my domain name and external IPs for privacy/paranoia issues, the name itself isn't something that will get by censors. The DNS servers are ones that score the highest in DNSBench from http://www.GRC.com, the Gibsdon Research folk [ShieldsUp etc], plus one from my the DNSexit folk that I get my dynamic DNS workings. The ad-blocking list I am using is a static text file with the offending blockage removed, I can surf to freebsd.org with no problem, as I detailed above, right in the middle of writing the previous post, my main machine went from its typical not finding freebsd, to finding it, and then not finding it, all in 10 minutes, where the only thing I changed was checking the box on the 'append parent suffixes of the primary DNS suffix' in the advanced dns config settings for the NIC/connection in windows.
I can't figure out how to copy from wireshark, I get little pieces, but the query for freebsd looks like this:
www.freebsd.org: type A, class IN
I'm doing something wrong here, image: https://skydrive.live.com/redir?resid=CD4A1DE1B932EC1E!96107when doing the testing above, when it changed from not working to working to not working, after the initial query, there was not another one, the initial query for ip-adress.com was normal. I'm sorry this is the best I can do at the moment, I have some things I am running late for right now, and will be gone for most of the rest of the day, but tonight I will figure out how to suck more data from wireshark, I haven't used it all that much so I got some learnin' to do in that regard.
Again, thanks, really really thanks, for taking so much time. Have a good one.

What does get by censors mean? I am more worried about the tld, for a private domain you use on your lan for your local machines. I would not suggest you use any sort of valid tld, you run into an issue where it could resolve on the public net.
using mydomain.lan or .local or .foo etc. would be better options.
The query for freebsd.or looks like that where - on your lan, or that is what is going out the wan of pfsense when you ask for it?
For you to get a response with your public IP as the answer, something has to answer with that? It should not be possible for an external dns to respond – so I have to assume pfsense is responding.
Your pointing to 127.0.0.1 - pfsense itself for dns. So did you at some point try and run unbound or tiny dns, or some other dns -- did you install bind for example.
What do you have in your Host Overrides in dns forwarder under services?
By default windows will add its primary suffix to queries when looking for stuff that does not answer. So what is domain your using locally? mydomain.org is a valid domain on the internet - this is not something you should be using as your primary domain on your local boxes. Unless of course you owned and controlled that domain and wanted to do that??
Lets fully understand your local domain and hostnames and how they query, and then we can figure out how what your seeing is happening.
PM me your details of your domain if you don't want it public. But I don't see how something like curseword.lan would be an issue. the .tld is part I am curious about. org, net, com, info, biz, etc.. not good choices for local domains if you ask me.
More than happy to remote in and take a look with you if you want. We could use teamviewer to one of your local hosts and then access your pfsense gui and shell with you watching everything that we do, etc.
Just send me a PM and we can schedule a good time.

Okay, this is the best I can do, PC tsub, has pfsense as sole DNS, the details of a DNS query that fails at the browser:

Now, PC ivy, has an external DNS server as primary, the browser browses to freebsd.org. The firrst line is something that started recently, don't know what causes that yet, I have to disable and re-enable the NIC and it connects and works fine, the words are copied from the ever-unhelpful diagnostic from windsows.
Windows couldn't automatically bind the IP protocol stack to the network adapter.
ivy has an external primary DNS, this is how a freebsd query went on it:

I've set something stupid somewhere, but have no idea what and how I did anything any differently than previous installs of pfsense. thanks for any info

So when you asked pfsense for www.freebsd.org it responded with the root servers. This is could happen I guess when you ask a server for a recursive lookup for something its not authoritative for and it won't do recursive for you. Normally it should just be a refused response.
But I did that query to the NSers you have listed – and guess what

Now notice how fast the response was!! 20 ms – so pfsense by default as you saw in my wireshark trace send the query you ask it to ALL your dns listed. And the first one that responds wins.. So when you query for www.freebsd.org and this guy at 199.192.200.41 answers first with the root servers and a NOERROR as status - pfsense will just hand that back to you.
Remove that guy from your list of dns servers and your issues should go away, the other servers seemed to respond correctly from my test.
edit: I would only suggest you use good dns, that server might have been listed in your benchmark software, but he does not seem to respond to recursive queries..
I asked him for www.goggle.com for example - and again he responds with just the roots

;; MSG SIZE rcvd: 243But he sure responds FAST ;) So he would be a problem child for all your dns stuff to be sure!! I would think you could be having more issues than your reporting with using him.
From a PTR query, that sure doesn't look like a legit public NS to me
;; ANSWER SECTION:
41.200.192.199.in-addr.arpa. 86400 IN PTR ct41.7wei.com.See where I bolded that he is not doing recursive lookups - he normally should respond with REFUSED vs sending you back roots.. But not sure what that box actually is or who configured it, or what its running for dns, etc.. etc.
This would also explain why you say it works for awhile and then stops working - if you get a response from one of the other NSers listed with the good info, then pfsense would hand that off to your client. But if he gets this garbage back of just roots, he would hand that off just as well. It doesn't know any better - just forwarding what your asking, and then returning what it gets back ;)
If your not happy with your ISP dns, or any of the other openpublic like google or open or norton, scrubit, etc. Then I would suggest 4.2.2.2 I have had good luck with it over many many years. I personally normally just run my own local that queries roots directly, this was working great when unbound was part of the distro.. And was suppose to be included with 2.1 but seems it has gotten put on the back burner. It will be great day when they fully integrate it into pfsense ;) And I always have my local copy of bind on my ubuntu box I can query, or I have box out in CA and some in EU I use for dns testing for geographic diversity when they are using geoip, etc.
Isn't DNS fun!!! ;)

THANKS!! I haven't tested it yet, but it sure sounds like the right answer. That DNS is one of 4 that DNSexit says I need to use, or at least one of them, there is an implication that the dynamic part won't work right if I don't use their server, but I've rarely used one of theirs, and been okay. I should have known better since DNSBench almost always failed on all 4of those, I assumed it was no response, which shouldn't matter, I'm not clever enough to realize that what I was getting was basically garbage. FUN FUN!
So far so good, got to freebsd, and ip-tools.com, and I just got this, the query without the period always returned the local address and had the local domain appended:
C:\Windows\system32>nslookup www.freebsd.org
Server: pfsense.fuckyouandfuckyourgod.org

"That DNS is one of 4 that DNSexit says I need to use"
Yes to point your domain to as your NS at your registrar, not to use for recursive lookups. That one returning roots is ns3.dnsexit.com
I just tested with your domain, and yes that server does respond as authoritative for your domain, but he does not allow recursive lookups. If those are the 4 your using… They have a really bad setup!!
Authoritative servers normally should NOT allow for recursive -- your just asking to be used in a dos, or have a dos against you. It would not be very difficult to keep those servers really really busy doing recursive to the point that they could not serve up the zones they are suppose to be authoritative for.. DNS can be used in an amplification type attack, you can send very small amounts of data, and get best more data in return. small query, large answer/work doing recursive.
And they claim 100% uptime since 1998?? From what I have seen I would have to say dumb luck ;)
None of those should be used as your forwarders in your pfsense setup. They are used when someone is looking up your domain. Not to be used when looking up freebsd.org or google.com, etc.
Just do whatever it is you do to keep your dynamic updated, I just looked and pfsense dynamic dns has dnsexit listed to keep updated on a wan IP change, etc..
As I stated before if you don't like your isp dns, there are other public dns you can use. googledns should work, if they don't have something close enough to you for your liking try the 4.2.2.2 one or 4.2.2.(1-6) works.
You could also use ntt servers - they allow public queries 129.250.35.250 or .251 you could use the ones at http://www.public-root.com/ they have 2 in US. You could use level3 -- they have a large dns setup, use 209.244.0.3 or .4
Or jut google for public name servers that you can query. But those you using are NO GOOD for recursive lookups ;)

That was the only dnsexit I was using, the rest came from running DNSBench, from Gibson Research Corp, at https://www.grc.com/default.htm , the site has a great deal of good info and tests, seems like a great resource, but probably too basic for you. The benchmark will configure itself with a custom list of dns servers to test, and the ones you mention he also has a great deal of praise for. It's surprising those aren't in my custom list, but I added them and they make a very good showing, so I'm adding the fastest one to the top of my list. Timewarner really sucks so I'm ignoring them. This is the first of about 54 servers tested.

Level 3 CommunicationsThanks again, I've been using the system extensively and only a couple of stray failures, nothing out of the ordinary!!!!
Oh, and thanks to all of the guys behind pfsense, it's amazing how simple it all is and so so easy to set up, especially considering the power/versatility.

"so I'm adding the fastest one to the top of my list"
The order doesn't really matter - you do understand that pfsense queries all the ips listed at the same time, and then uses the one that answers first. Prob doesn't make a lot of sense to have more than a couple of them.
Nor is it going to make much different .016 vs .018 or .05 vs .06
Yeah I know Steve – he likes to make a lot of noise ;) Don't you recall how the raw sockets of XP was going to end the internet as we knew it? Or the whole WMF nonsense? I really wouldn't recommend that site to anyone, be careful of hype he likes to promote. Sure some basic info is there -- and he can explain things in simple terms, but no I wouldn't recommend that site to be honest. Do a simple google "What the World Thinks of Steve Gibson" some fun quotes to be read.

Wow, thanks for the heads up, I knew none of that, all I know of the guy before was his site, the utilities there, like ShieldsUp and DNSBench, which I'd seen recommended by somewhere reputable, seemed genuinely useful, and I don't have the technical chops to seriously evaluate much of any of it. That 'What the world…' page, pretty harsh. Well, great, now I feel even stupider, especially because empty hype disgusts me no end, and false hype is way worse. Have a good one.
