Howto: Setup a DNS server with bind

location: ubuntuforums.com - date: August 14, 2006
After looking on Ubuntu forum for an easy step-by-step howto for instaling a DNS server, I decided the best idea would probably be to write this howto myself.... So, here it is! Step 1: Install Ubuntu dapper, or use your WORKING installation. Step2: Install bind 9: Code: sudo apt-get install bind9 Step 3: Configure the main Bind files. Usually, if you install Bind from the source code, you will have to edit the file named.conf. However, Ubuntu provides you with a pre-configured Bind, so we will edit another file: Code: sudo vi /etc/bind/named.conf.local This is where we will insert our zones. By the way, a zone is a domain name that is referenced in the DNS server Insert this in the named.conf.local file: Code: # This is the zone definition. replace example.com with your domain name zone "example.com" { type master; file "/etc/bind/zones/example.com.db"; }; # This is the zone definition for reverse DNS. replace 0.168.192

How do I find my DNS servers?

location: ubuntuforums.com - date: January 15, 2009
In windows I can type ipconfig/all to see my DNS servers what can I do in ubuntu to find my primary and secondary DNs servers. Interestingly my Ubuntu network connection is working fine but windows 7 is all fubared and I wanted to try setting a static IP address to see if that fixed it. The problem is I need my DNS servers to do so and I have no idea what they are.

Hey In a few days I am jumping on cloudhosting for hosting my websites - and learn a bit more about servers. But my one problem is the DNS server for my domains I want to host on the cloudhosting. Any of you got a tutorial for setting up dns server with domain names - a tutorial that is not 5 years old? Thanks

specify multiple DNS server

location: ubuntuforums.com - date: July 4, 2008
Hy guys! I simply want to use multiple DNS servers , such as they are specified in Windows like Alternate DNS. I have tried to edit /etc/resolv.conf to be : nameserver first.dns.server.1 nameserver second.dns.server.1 but it seems that it is using only the first entry in the file, so if i comment the first nameserver it will correctly lookup the hosts that are to be found by the second nameserver .... but the machine names corresponding to the first nameserver won't be available... by the way, how do i flush these changes ???(is it enough to only edit and save the /etc/resolv.conf file?) thanks in advance!!

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.

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.
