Changing default DNS Server

Hi,
I'm a new BT broadband customer.
Like most, I have a house full of pcs and gadgets connecting to the Internet. Many belong to my children. Naturally, as a responsible parent, I want to do my utmost to limit their access to inappropriate content.
The basic first line of defence is obviously to have dns filtering.
However, my Home Hub 3 won't let me change the default dns gateway to some filtering service like OpenDNS, nor is there anything to suggest that BTs own dns service has this capability.
Can you please, as a matter of the greatest urgency (I believe that my children are currently able to access the most inappropriate content on their mobile devices), tell me how to get this in place.
Thanks

Many thanks for the replies on this thread - they are much appreciated, especially the email address.
As I said, I would regard dns filtering as the first line of defence. And a very necessary one, as my main concern is with my kids wifi connecting mobile devices.
What interests me about all this is that, as people have pointed out, there are ways to set the dns gateway per device. To my mind that completely undermines any argument for not allowing it to be changed on the HH.
Why might BT want to disable dns setting in the Home Hub?
i) Because they can then offer valuable dns based services, such as 404 redirection?
   But users can override the dns setting on each device!
ii) Because it is one less thing that could be miss-set, so cutting down support calls?
   But users can override the dns setting on each device!
iii) Because Government might ask us to ban access to certain sites and controlling the dns lookup would help us do this?
    But users can override the dns setting on each device!
Am I missing something here? Is there actually a really good reason - because I would shut up if there was one!
Meanwhile, my kids remain unprotected for a 3rd day

Pragmatically change the DNS server

I have been trying to figure out how to write a program to change the DNS server, like you can in the control panel. I have played with Resolv.conf and a whole bunch of low level APIs.
From the terminal window, things like nslookup work (use the right dns server) but Safari doesn't. It still is using the original DNS server. I can stop and start safari and go to web pages it has not visited before and it still uses the old DNS server, so its not just pulling up cached pages.
It seems the low-level API stuff doesn't work for higher level applications like Safari (its the only high level app I know of that uses DNS to test with).
What is the API to use to change the DNS server address such that everyone,, like safari, will use the new DNS address?

Yeah, but I am changing all the DHCP entries in the system and it still gets out. However, it is solved by updating the system config. I was just curious as to where it got its DHCP server info from when the system config was blank and resolv.conf was set to my DHCP server.

Change of DNS server setting caused Exchange outages!

I am trying to google/bing my way through this, but here are the main points:
All remote Exchange servers had a) static IP addresses and b) were instructed to use DNS servers in Edmonton and Calgary
If WAN links dropped, they lost DNS
SOLUTION! Point remote servers to the domain controller in that location as the primary DNS server. WAN outage means Exchange still resolves names locally.
Well the day came and we add the local DNS server for each remote site as the primary DNS server at the top of "DNS server addresses, in order of use" portion of advanced TCP/IP settings dialogue box.
A reboot is performed
Voila! Exchange shits the bed! Hub transport servers in Edmonton and Calgary cannot resolve remote server names; as in no host(a) record exists for them anymore. And we have a 91 minute outage until the DNS is sorted out (ipconfig /registerdns run on each
server).
Has anyone encountered this or have some deep knowledge of DNS (relative to my own) that could at least throw out a theory as to why this might happen?

Hi, please issue Get-ExchangeServer -Identity "ServerName" -status | fl and check:
CurrentDomainControllers
CurrentGlobalCatalogs
CurrentConfigDomainController
The server must been linked to the wrong server. You can change that in powershell too.

How i can change default Deployment server in Creator 2 ea 2.

Hi
Thank you for reading my post.
I want to change Creator 2 ea 2 , deployment server
I used to use centeralized deployment server . and i want to change Creator server , and set it to that server.
How i can do this ?

Here is what worked for me.
changing the default application server.
1) Verify that JSC2 is creating a WAR file in the project's dist directory.
2) Download the Sun Java System Application Server 8.1
3) Install the application server on another computer. E.g. 192.168.1.110
I changed the default port from 8080 to 80 because I wanted to port forward.
Don't know if this is required.
4) Start the server! Browse to 192.168.1.110:80 and verify the server started.
5) Run the admin console (192.168.1.110:4848) and manually deploy the WAR file
If you can't do this, it wont go.
Your browser might appear to get stuck. Wait for it to finish! Check your logs for errors.
If you get stuck, doublecheck that the server directory isn't write-protected.
Test with a browser 192.168.1.110:80/ProjectName
6) Tell JSC2 about the new server
Servers Tab -> Remote Servers -> rightclick -> Add Remote Server...
Select the right kind of server (Sun Java System Application Server 8.1)
Admin Host: 192.168.1.110
Admin Port: 4848
Username: admin or whatever
Password: shhhhh!
7) Configure JSC2 to deploy the project to a different server during testing.
Projects Tab -> Right-click the project -> Properties -> Run -> select the new server.
8) Click the little green triangle and it should deploy and start a browser to test.
Trouble-shooting:
- Problems will occur if you attempt to do things to fast. Don't cancel out of operations.
- Don't modify any of you build.xml files
- Don't compress the war file
- Restart everything if you hit a problem
- Don't ask me, I don't know anything about it. I just fiddled with it till it worked.
- Turn off Netlimiter! (or any other bandwidth manager)
- Turn off Antivirus monitoring software (stuff runs faster - security rish though)

Default DNS server unknown its coming while resolving`

Hi
i have windows 2012 domain controllers, able to successfully resolve dns queries.
But the problem is while resolving default server field its coming unknown. i created reverse lookup for dns server(Domain controller) after that host name is coming..
But after one day again hostname disappeared, default server field unknown coming..
If anybody knows this issue..

Hi,
Have you checked if the reverse lookup record is still present in the reverse lookup zone. Domain Controllers use dynamic registration to register A/PTR records for itself. Make sure Enterprise Domain Controllers group has permissions over the records so
these can be updated. This is found in on the security tab at the record/zone propetties. If you manually created the PTR record then it should have no timestamp therefore it will not be scavanged in case you enabled that function.
Hope this helps.

Calin

Change default X server to tty1

The default X server starts at tty6. How to change it to tty1 or others?

How exactly do you start it? https://wiki.archlinux.org/index.php/Start_X_at_Boot
exec xinit -- /usr/bin/X -nolisten tcp vt7
'vt7' means it will start on tty7.

DNS Host record of a computer is deleted after you change the DNS server assignment

Hi All,
This is a critical bug in Windows 7/Windows 2008 and Windows 2008 R2. Is there any way to get rid of it? I am planning for for a deployment with new DNS server IPs.
Thank you.

Changing the default dns server

I have edited the file /etc/resolv.conf and added the nameserver of the google public dns. How can i verify if google dns are used?

Install dnsutils.

DNS utilities: dig host nslookup
[bill@Jeremiah ~]$ dig www.google.ca

This is the output of my machine which is set to use Google DNS. Notice the "SERVER" part: 8.8.8.8 which is Google DNS.
Also, once you've edited resolv.conf then a reboot may overwrite your settings.
Put:
nameserver 8.8.8.8
nameserver 8.8.4.4
In it for Google DNS, THEN:
sudo chattr +i resolv.conf
To make it immutable so no other program can overwrite (change) the file. If you ever want the file to be changeable again "chattr -i resolv.conf"

Changing primary DNS server in Unity 10.5

We have a Unity server that has a DNS setting that is no longer valid. I was wondering if it would change the license MAC and invalidate the licenses if I were to change that primary and secondary DNS setting.
Thanks,
Jordan

I believe you only need to delete and add again in PLM if you do that, and you're using co-res PLM where you're changing that

Default DNS server IP addresses

I was having problems tracking down the default IP addresses for the FIOS DNS servers and saw others were having the same problem. Finally got them (at least, the ones for Maryland FIOS) and figured I'd post them in case they were of use to others:
4.2.2.1
4.2.2.2
4.2.2.3
4.2.2.4
4.2.2.5
Hope this can help someone.
Solved!
Go to Solution.

DNS Server change

Forgive me if this has been asked before, I've been searching for an answer and can't seem to find one.
i am using the previous version of iweb and i have just published my site.
I am trying to figure out how to use my registered domain name.
I know i need to change my DNS server but don't know how to find out what the .mac one is..
and if iweb 06 can even do this.
also, when i published my site to my .mac account the first page comes up but none of the other pages that i linked from the main page.
any thoughts or suggestion would be greatly appreciated.
aavalenti

Hi aavalenti,
For the Domain I'd like you to have a look at the following page
http://alyeska.altervista.org/en/iWeb_Domains.html
However .mac doesn't provide DNS servers.
For the question about the page and not working links you need to reupload the site from iWeb by making a publish all. Seems like some pages aren't on the server.

Cédric

Changing DNS Server on Lion OD/Kerberos Master

I have an interesting task ahead of me, but am unsure how best to proceed.
I spent days setting-up my new Lion Server and attached Pegasus RAID array. There are 140 users, 8 share points, and hundreds of different ACL permutations within the AFP shares that reside on a thunderbolt-attached Pegasus array. The only services running on the box are DNS, AFP, and OD.
I added a secondary server and intended to use it as an OD replica (redundancy is great, but the speed increase would also be great). Problem is that I set them both with .local names. I can't get an OP replica to run unless they are within the same DNS zone, and so that is what I am looking to do.
I have read a lot of Apple support documents and a couple books, and understand that changing the DNS server will likely break OD (certainly Kerberos).
My goal is to re-zone the DNS while preserving OD users, groups, passwords, and most importantly: how they relate to the ACLs on the Pegasus unit (I would very much like to avoid having to re-do all those permissions - particularly within the Lion Server UI).
If I need to do a re-install and then laterally migrate, I certainly can. I am hoping for the path of least headache to be sure.
If anyone has advise on how to do this as painlessly as possible, I would appreciate it.

Will the OD archive contain the old DNS settings and somehow muck this up?
I don't know the answer to all of your questions but I do know this: If you have an OD archive from a master that had an incorrect hostname, this information was put into your archive.
"Open Directory" is comprised of three components: PasswordServer, LDAPv3 and Kerberos. This is what is backed up during an OD Archive. So if you have a archive from a machine with messed up DNS, I would not trust that everything will be fine after the restore.
Maybe somebody else can chime in and offer you further help...

Can't change DNS server setting on airport express

new airport express, comcast cable ISP, i cannot change the DNS server settings, they are greyed out. why is there no way to change this?

Mark-
Did you get the AE to actually use the OpenDNS servers? I have the new AE and Airport Utility 6.3.1 and while I can enter the OpenDNS server settings (208.67.222.222 and 208.67.220.220), they don't work. When I use a Wi-Fi connected device (my iPhone, for example) it sill uses the Comcast DNS settings, totally ignoring the OpenDNS settings. I don't know when they stopped working, but they worked in the past. I've used the old Airport Utility as well (5.6) and it says the OpenDNS settings are active, but they aren't.
I want to use the OpenDNS settings for Wi-Fi connected devices in my home for content filtering. If anyone knows of a DOCSIS 3 cable modem that allows setting DNS servers, that would be an option too, but unfortunately, my Motorola SurfBoard SBG6580 does not.

How can I get my Tiger Sever to look at itself as a DNS Server

I have installed Tiger server remotely and have no GUI.
I want to change the DNS Server ip address with that Server
If I had access to the System Prefs/Network panel I could simply make the change.
Can I do this via a command line in Terminal ??
Thanks

Two options come to mind.
First is networksetup, the command-line interface to network settings:
networksetup -setdnsservers "Built-in Ethernet 1" 127.0.0.1
(you can add additional name servers in order if you want).
The other is to just rewrite /etc/resolv.conf which stores the active name server settings (although this might get rewritten at boot).
