Changing DNS in Ubuntu 12.10 and 12.04
location: ubuntuforums.com - date: October 31, 2012
Okay so I was in the process of making Firefox perform Google searches from the address bar and realised that I was being redirected to my ISP's page not found screen. This I determined was because of the DNS that was set by default in Ubuntu to 127.0.1.1 or 127.0.0.1. I went to change this to Googles DNS 8.8.8.8 and 8.8.4.4. To do this in previous releases
Code:
gksudo gedit /etc/resolv.conf
Change this:
Code:
nameserver 127.0.1.1
to this:
Code:
nameserver 8.8.8.8
nameserver 8.8.4.4
This no longer works in Ubuntu 12.10 maybe not 12.04 either the only way that I found around this was to:
Code:
gksudo gedit /etc/resolvconf/resolv.conf.d/head
and to add this:
Code:
nameserver 8.8.8.8
nameserver 8.8.4.4
at the bottom. Then run this code to update the resolv.conf file
Code:
sudo resolvconf -u
If there is a better way to do this please let me know as I am sure others would appreciate it was well.
what's my dns server address?

ubuntu as DNS server
location: ubuntuforums.com - date: April 12, 2013
I am new here. Hope my post is clear and appropriate.
I configured my ubuntu 12.10 in VMWare as my DNS servers. My friend designed a website. He tried to access his website using my DNS server as preferred DNS server, which is in the same network. I stored his website's domain name and ip address in Forward Look up zone and reverse look up zone.
He failed to access his website but he could access all the other sites like google and yahoo using my DNS since my DNS server is forwarding it to ISP's DNS server.
In short, my DNS server cannot resolvequeries using its data base but simply forwarding queries to ISP's DNS server as I used it as forwarder. Kindly provide me with a solution of how DNS could resolve a query using its database (Forward and Reverse look up zones).
Thanks much
anytime
DNS server not working
location: ubuntuforums.com - date: March 8, 2013
Hello!
I've been trying to configure my own server but I'm currently stuck and I don't know what else to try.
I've got a domain ganganadores.cl and I'm trying to host my own DNS servers.
I'm using ISPConfig 3 and Bind9. I've used the guide from http://www.howtoforge.com/perfect-se...ot-ispconfig-3
For some reason the DNS server is not working, if I try pinging ganganadores.cl I get an error as the server can't be found.
http://www.intodns.com/ganganadores.cl shows the same thing.
What can I be doing wrong? here is my ISPConfig.
Dynamic DHCP update to DNS
location: linuxquestions.com - date: December 31, 2011
Ok, I've thrown everything at this, and I cannot get my Ubuntu 10.04 server to handle dynamic DNS updates from DHCP. The IP lease itself is fine. It's only the DNS update.
Unfortunately, that's worse than where I used to be. In earlier attempts to get it working, I saw error messages about dynamic updates timing out. But now, I get nothing at all.
The last try for dynamic updates gave these messages from the DHCP server's syslog:

IPv6 DNS server using BIND
location: linuxquestions.com - date: July 14, 2009
hi,
I am trying to setup BIND as a DNS server for local IPv6 name resolution within a LAN.
heres the network:
Ubuntu 8.10 running BIND 9.5.0-P2
IPv4 - 192.168.1.8
IPv6 - fe80::a00:27ff:fe56:7f27/64
hostname - dnsserver
Windows XP SP2
IPv4 - 192.168.1.7
IPv6 - fe80::a00:27ff:fea8:81ed%5
hostname - winclient
Both the IPv6 are autoconfigured, while IPv4 addresses are via DHCP.
As long as iam working with IPv4, things work. I forced dnsserver's IPv4 address on winclient's DNS settings.
i can ping winclient and it resolves its IPv4 address. (i get replies from the IPv4 address)
However, as soon as i add dnsserver's IPv6 address as DNS using

Ubuntu dns server SRV records
location: linuxquestions.com - date: April 11, 2011
I am quite interested in one thing. I am trying to code my dns server that when i connect to one of my subdomains it connects not only to an ip adress but to an ip : port adress.
For this i tried using SRV record, but with lack of success.
Dns server specification:
OS Ubuntu server 10.10 and using bind9
I have configured everything so that my subdomains work on an ip address, but i need some of them to work on ip : port too.
in my brfconcept.lv.db file i used: (what i mentioned below isn't the full content of the file)
Code:
[SOLVED] DNS lookup failed ubuntu server routing between subnets.
location: linuxquestions.com - date: March 18, 2013
So, I'm routing traffic between subnet .0.0/24 and .1.0/24
From Dev. A, I can get a ping to reach Google using an IP, and can obviously get to the site using the IP, -but- whenever I use the URL, a DNS lookup fails.
I've spoken to someone who thinks that it's something to do with DHCP not passing on DNS information to the leased IP's. And that the Device will be looking for DNS information from the access point, and not the router.

^^ link to a visual example of what I'm talking about.
Basically, ping from Dev all the way through the network to the internet works. But DNS fails.
Any clues as to what might be causing it? I'll do some work on it later and keep you all informed.
Thanks in advance for the replies.

Ubuntu Server manually set DNS
location: linuxquestions.com - date: October 9, 2012
Hey LQ,
Quick question here. I have a ubuntu server up and running with a static IP address, no issues there. The problem I'm having is that whenever I reboot the machine it seems to lose it's DNS settings. I can set the DNS settings manually by doing a sudo nano /etc/resolv.conf and manually adding in "nameserver 192.168.1.254" and then DNS begins to work, but for some reason I lose this configuration upon reboot.
How do I get around this?
