Are DNS requests intercepted?

Hi,
There's a site I'm trying to get to, but when I type in the address & go I always end up at a different site.
I've asked local friends whether they have the same problem & they don't.
I've flushed the dns cache on my pcs (I have the same problem no matter which one I use).
I've restarted the router (which supposedly clears the dns cache there).
I've tried using my phone to go the wireless route.
I always end up at the wrong address.
Thinking it might be an error in the BT DNS server's info I tried changing the dns servers on my PC to Google's and then OpenDNS.
I still end up at the wrong page.
What I'm wondering is whether changing the dns settings on my PCs actually has any effect.
Does BT intercept dns requests & route them through their own servers?
Many thanks.

Hi.
If, by altering the DNS server, you end up at the same place - this indicates it's a local issue.
Can you say what the website is ? If you don't wish it to be public, send me a private message with the website and I'll investigate.

WRT1900AC: Can it block DNS requests?

Hello,
Can the WRT1900AC block DNS request from devices in a home network to public DNS service like GoogleDNS? Can anyone tell me what steps are necessary to accomplish this?
I tried to follow instructions found on the web but I could not add static routes under Advanced Routing, I got errors either about the network submask or the Gateway (mine is 192.168.1.1 and is not accepted). i don't know what to enter in these fields and also what Interface to select (LAN/Wireless or Internet).
My firmware version is 1.1.8.164461.
I would appreciate any help.
Thank you,
Luiz

Hi,
Thanks for replying. I haven't contacted support yet to confirm you suspicion, My cable modem is a Motorola SB6141. I have done some basic research that indicates that it is not capable of NAT.
However, I was able to configure a static route in my router,using the cable modem IP asgateway. After this my ping requests to Google DNS (8.8.8.8 and 8.8.4.4) started to fail. This is probably still not what I need. I don't understand why I can't save my router's IP as gateway as indicated here: http://help.unotelly.com/support/solutions/articles/193662-setup-static-routes-on-linksys-and-cisco-... This link alerts to a bug in Linksys routers but the error message I get is not "invalid static route" as indicated.
Thanks,
Luiz

DNS request timed out. timeout was 2 seconds. *** Request to self timed-out

I am having an issue with one of my domain controllers (Server 2012 R2). It is a DNS server as well and it times out 100% of then time when attempting connect to either of the two trusted forests that are setup as conditional forwarders. There is also a
delay or a time out the first few times when attempting to resolve an external site such as google.com. The domain controller functions fine. All routing seems to fine, because I can telnet on port 53 to the trusted forest's DCs. They can even use the problem
DNS server to resolve hosts. It just does work from my controller to the other forest. Here is an example of what is happening.

There is a firewall between these networks, they connect via campus fiber. I created an any rule to rule that out. I am thinking the DNS server is corrupt, but I cannot figure it out.
Dcdiag /test:dns says everything is great.
Any suggestions?

Hi,
According to your description, my understanding is that the problem DC is configured with conditional forwarders to resolve names about other 2 trusted forests, and always times out. Besides, there is a delay or a time out the first few times when attempting
to resolve an external name.
Use NSlookup to confirm that if the conditional forwarder works. Open CMD on problem DC, type the command below and each line end with enter:
Nslookup
Server <IP address of the condition forwarder which used to resolve names on trust domain>
<name of the trust forest which you want to resolve>
If it works, try to increase time-out period:
Properties of Conditional Forwarders – Number of seconds before forward queries times out
– change the time.
If it doesn’t work, turn on exhaustive debugging mode. Open CMD on problem DC, type the command below and each line end with enter:
Nslookup
Set d2
Server <IP address of the condition forwarder which used to resolve names on trust domain>
<name of the trust forest which you want to resolve>
Post the result here.
Besides, for internet/external name resolving problem, we usually have another DNS server(except for DCs) which connected to Internet/external and used to resolve external/Internet names. And on DCs, configure forwarder and use forwarder to resolve external/Internet
names. If it is your case, check the forwarder setting on the problem DC, or use ping to test the network connectivity. Confirm that if the delay of name resolving caused by network delay.

DNS requests from Solaris 10 box to Bind/MySQL DNS server fail

We have some servers running solaris 9 and some running solaris 10. We also have a DNS server setup running BIND with the MySQL backend. When I query the DNS server from our solaris 9 boxes, they always work just fine. However, when I query the DNS server from our solaris 10 boxes, they always fail. Queries to other DNS servers from the Solaris 10 boxes work just fine - they only fail when being sent to this particular DNS server. Here's exactly what I'm doing:
ON SOLARIS 9 BOX:
bash-3.00$ nslookup google.com calo-sunset
Server: calo-sunset
Address: <IP_OF_DNS_SERVER>#53
Non-authoritative answer:
Name: google.com
Address: 64.233.187.99
Name: google.com
Address: 72.14.207.99
Name: google.com
Address: 209.85.171.99
ON SOLARIS 10 BOX:
bash-2.05$ nslookup google.com calo-sunset
*** Can't find server name for address <IP_OF_DNS_SERVER>: Non-existent host/domain
*** Default servers are not available
In the case of the SOLARIS 10 box, <IP_OF_DNS_SERVER> is correct - it knows the IP address of the DNS server, but apparently it doesn't recognize that it's actually a DNS server.
I am utterly perplexed by this. It seems to me that a DNS request is a DNS request, regardless of your OS. Clearly something is different from Solaris 9 to Solaris 10 though because the requests fail on all of our solaris 10 boxes, and they succeed on all of our Solaris 9 boxes. Incidentally, dig requests from the Solaris 10 box also fail, where they succeed on the Solaris 9 boxes.
I don't really know what other information I could offer that might be useful. If you have any information at all about this or ideas on what I might try to troubleshoot/fix it, I'd love to hear it. Thanks in advance.

First off, I am an idiot. I got this entire post backwards. The fact is that the DNS requests work swimmingly well on our Solaris 10 boxes. They fail on our Solaris 9 boxes. I don't know how I managed to read this post all of these times and not notice that I got that backwards. Nice.
In any case, I've found the problem. It was non-trivial to me because I am not terribly familiar with the inner-workings of DNS. To those who are, it may seem painfully obvious. To me it certainly was not.
The problem was that the DNS server (BIND 9 with MySQL backend) did not contain a reverse DNS entry for itself. Apparently this is a big problem for Solaris 9. I got a hint that this might be the cause when I turned on verbose debugging info when I ran nslookup (nslookup -d2). I had to add the PTR record for the DNS server itself. I don't know why Solaris 9 would require that a DNS server contain reverse DNS information about itself, but sure enough it does. As soon as I added that info, the Solaris 9 boxes were able to successfully query the DNS server. Very odd.
Anyway, I doubt anyone else will come across this problem, but if you do, now you know something that might fix it.

Nslookup: DNS request timed out. time out was 2 seconds. (When the primary DNS is down)

Hi All,
I have set up 2 Windows Server 2012 domain controllers (DCA & DCB). DCA points at DCB as the primary DNS, and itself as the alternate DNS. DCB points at DCA as the primary DNS, and itself as the alternate DNS.
When both DCs are running and if I do an nslookup on DCA: The result is as follows:
Default Server: dcb.testdomain.com
Address: 30.30.30.2
nslookup on DCB:
Default Server: dca.testdomain.com
Address: 30.30.30.1
Client PC (Windows 7 Pro):
1st DNS : 30.30.30.31
Alternate DNS: 30.30.30.32
nslookup on the client PC
Default Server: dca.testdomain.com
Address: 30.30.30.1
Up to here everything is fine. Now if I turn off DCA, and do an nslookup, the result is as follows:
DCB nslookup:
DNS request timed out.
time out was 2 seconds.
Default Server Unknown
Address: 30.30.30.31
Client PC nslookup:
DNS request timed out.
time out was 2 seconds.
Default Server Unknown
Address: 30.30.30.31
I waited for more than 15 minutes an tried again, it didn't help.
I have been reading a few similar posts on this matter, but couldn't find the answer.
I would expected it to display the DCB when I do an nslookup.
Question 1: Shouldn't that display DCB rather than displaying a time out message when I do nslookup?
Question 2: The fact that it displays a time out message, does it mean that more configuration needs to be done? If so please kindly advice what needs to be done.
I did an ipconfig /displaydns command. I realized that the order of DNS have changed on both DCB and the Client PC:
Now, they both display DCB on the top of the list, whereas they were displaying DCA on the top of the list prior to the shut down.
Question 3: Does it mean that the Client PC now knows that the 1st DNS is down and so it's using the 2nd DNS?
If so, why does the nslookup display the time out message?
Question 4: Is it possible to configure either of DNS Server or the DNS client, so it displays the 2nd DNS when the first DNS is not accessible and when I do nslookup?
Thank you for.

Hi Ton_2013,
Based on my understanding, the issue we are experiencing is that: when the primary DNS server is down, the result of the tool Nslookup is to diaplay the time out message at first. Right?
Based on my knowledge, timed out message is means that the server did not respond to a request after a certain amount of time and a certain number of retries. Because the primary DNS server is down, it can't respond to this request and time is out. When
the primary DNS server can't respond, the secondary DNS server works to ensure effective work. And the order is changed as you said.
As to the reason why the result is still the same even when the order has changed, we can try to use Network Monitor to capture network traffic and view and analyze it to find the cause. And the cause may be the cache. For your information, please refer

SL constantly making DNS requests for "local" ?

I've been troubleshooting a problem with my DSL router crashing and noticed that my Macs continuously, even when idle, have nearly 200 open connections at any given time, whereas my Windows boxes peak at 50 and drop down to under 10 when idle. The Macs are running SL 10.6.2.
Poking around in the router logs, I found that the Macs are constantly making udp DNS requests to my router, even when I'm not browsing or doing anything else. tcpdump of udp and port 53 gives me the following:

192.168.0.8 is my Mac and 192.168.0.1 is my DSL router. The Mac is ip'd using DHCP on the router. The router sends DNS requests from my clients out to my ISPs DNS servers.
Eventually, the DNS requests timeout and I get this:
00:21:43.145103 IP 205.171.3.65.53 > 192.168.0.8.52959: 38258 NXDomain 0/1/0 (98)
00:21:43.450086 IP 205.171.3.65.53 > 192.168.0.8.55938: 46832 NXDomain 0/1/0 (98)
00:21:43.763304 IP 205.171.3.65.53 > 192.168.0.8.50265: 62399 NXDomain 0/1/0 (98)
00:21:44.049705 IP 205.171.3.65.53 > 192.168.0.8.59991: 5960 NXDomain 0/1/0 (98)
It's a never-ending cycle that eventually kills my router.
If I'm reading the tcpdump output correctly, SL appears to be looking for some server named "local" 3 times every second. The TTL is roughly 90 seconds, so 3 requests/second gets me to an average of 180 connections at any give time -- which is approximately what my router is showing. If I do start browsing the connection count goes even higher. Trying to use both Macs at the same time has caused my router to crash due to running out of memory (it's obviously a very weak router .
Can someone give me some insight into what SL is doing and how I can stop this?
Thanks,
Randy

Does this server handle DNS requests?
If so, make sure under the local static IP for DNS servers you can try 127.0.0.1, and server IP.
Under the DNS tab make sure you have the ISP IP's under forwarder.
As a safety open terminal and run
su changeip -checkhostname

Cbac and dns requests

can anyone tell me why my dns requests on cbac are not working, I allowed everything from inside out, but dns requests are not allowed for some reasons...

I have set up two public dns servers, it works ok until i enable access-list 102, i solved this problem by adding to acl 102 entry permit tcp any eq 53 any, but on different router (also 2911) everything was ok and cbac and same config were similar. What could be wrong?

Routing DNS requests in a zone to a default host

Hi,
What I'd like to do is to direct all DNS requests for non-existent hosts to a single host by default. So even if I haven't defined a hostname in my zone, the request will still resolve (to this default host). Any ideas?
Ben

It's possible to do via wildcard DNS, but you cannot do it via Server Admin (it doesn't permit the * for the wildcard name), therefore you have to get under the hood and edit your zone file directly.
You'll need to find your zone's domain file in /var/named and add a line like:
* IN A 1.2.3.4
(where 1.2.3.4 is, obviously, the IP address you want all unknown addresses to point to).
You'll also need to increment the serial number in the SOA record near the top of the file (otherwise your change won't be noticed)
Restart named (e.g. via killall -HUP named or via Server Admin), and now any lookup for an unknown host will return the specified address.

DNS request timed out. timeout was 2 seconds

Hi
Why it is saying DNS request timed out was 2 seconds and showing the IPs under non-authoritative answers?
This is member DC windows 2008 R2. Primary DNS is set as 127.0.0.1 and secondary DNS is set to 192.168.10.6 which is main DC.

Username and password are being requested by

I can't open my firefox browser. An authentication required message pops up saying- a username and password are being requested by https://proxyvip.econ.mpg.de:444. The site says "Radius" - What do I do to get firefox working again? i can't do anything with it

You can check if you can start Firefox in <u>[[Safe Mode|Safe Mode]]</u> by holding down the Shift/Options key.
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
See if you can use the Profile Manager to start Firefox in Offline mode.
*http://kb.mozillazine.org/Profile_Manager
Try to start Firefox with the about:blank page by creating a copy of the current Firefox desktop shortcut and add a space and <b>-url "about:blank"</b> to the target/command field.
If that allows to start Firefox then check the connection settings.
*Firefox > Preferences > Advanced > Network : Connection > Settings
*https://support.mozilla.org/kb/Options+window+-+Advanced+panel
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

What are you talking about?
Either restate the question, or post in your native language. "So i request the concerned authority to provide me RESTORE PASSWORD to improve the status of my iphone 4" Is unclear at best.
If you're having some kind of problem, then explain what it is including the exact text of any error messages you're getting.

How to drop DNS requests for banned sites?

Hi
I'm looking to create a number of signatures to drop DNS requests for banned sites, the only way I've successfully implemented this is creating a signature (string UDP), to drop any UDP/53 traffic containing the regex string of banned site.
I would like clarification from any experts to verify that this is the only way of acheiving this, I know that there's a Service DNS Engine, but I can't seem to specify the FQDN within this. I'm not sure if I'm missing something?
Many thanks

You're on the right track. A custom UDP signature is the only way you'll find the requests you want to drop.
The DNS engine does not allow for custom string matches.

DNS request behind content switch: troubleshooting

Hi, sometimes we experience problems resolving a dns name behind a content switch. The problem solves himself after 5 minutes or something like that. We see the dns request on the dns servers subnet. It looks like the is a problem when the packet returns. I'm thinking of a nat problem. How can i best troubleshoot this?

Can i e-mail you the config file? I will also e-mail as soon as possible a network capture in front of the CSS. Where can i e-mail it? For the moment dns is working so i will have to wait for network capture untill it fails again.
Kind regards,

DNS request when Anyconnect launch the tunnel

Hi, just a quick question, I am trying Anyconnect client v3.1.03103-k9. I would like to setup an ipsec tunnel on a private ip, the IP has no dns entry. If I specify the IP address and try to connect the tunnel does not come up as there is a dns request to resolve the entry. Can I bypass this dns request ?
Thanks,
Jerome
