Questions[dnsmasq](server)

I'd like to resolve a domain name somedomain.com to a CNAME (AWS load balancer, e.g. some-balancer-1213231237.ap-southeast-2.elb.amazonaws.com), but only locally.

What I mean to achieve is that whenever I try to visit somedomain.com, I want to be served by the above mentioned load-balancer - this should only be limited to my own computer.

It's not possible to achieve this by editing /etc/hosts as in there only A records (IP addresses) can be mapped. I read somewhere that dnsmasq would be the most robust solution to achieve this. However, the documentation is very unclear about how this can be achieve. I'd appreciate your advice and perhaps a piece of config with an example. Thanks!

I would like to use only dnsmasq to forward all dns requests to google's dns server and disable dhcp...

How can I achieve this result?

I'm running Ubuntu server on a computer used as a wireless AP, but this AP should resolve all DNS requests to an internal IP address rather than actually performing the lookup.

I want to do the same thing that paid public WiFi hotspots do - you can connect but if you attempt to load any websites they show a default page. I've noticed that they do this by resolving all domains to an internal IP address.

I've added these lines to /etc/dnsmasq.conf:

# Add domains which you want to force to an IP address here.
# The example below send any host in double-click.net to a local
# web-server.
address=/com/192.168.2.1
address=/uk/192.168.2.1
address=/org/192.168.2.1
address=/gov/192.168.2.1
address=/net/192.168.2.1
address=/us/192.168.2.1

which works fine for those TLD's, but I'd like to be able to do it with all domains so I can sleep at night.

I'm working on a network with ~10 kubuntu desktops (and numerous servers and IP phones) and am trying to get dnsmasq to specify another dns server as a failover. I tried using

server=192.168.0.90

but that just added the single dhcp/dns server to /etc/resolv.conf on my test machine (dynamic IP and freshly rebooted with no lease).

I and a small group of developers have just moved to a new office, and I'd like to set up dnsmasq on our development server, so when we deploy web apps there, we don't have to edit our own hosts files. We have a router at 192.168.3.1 which we don't have access to. I figured I'd install a DNS server on the development box, and we all record its IP as a secondary DNS server. Unfortunately, I'm struggling to make this work.

The name of the devel server is devbox, its IP is 192.168.3.99, and it's running the latest Ubuntu Server (Karmic)

My computer is running Ubuntu Desktop (Karmic)

What I'd like to achieve

Let's say I have three websites, website1, website2, website3, running on the development box. I'd like to access them by the URLs:

http://website1.devbox
http://website2.devbox
http://website3.devbox

So I have configured Apache on the devel box, installed dnsmasq, and put the following lines into its hosts file:

192.168.3.99 website1.devbox
192.168.3.99 website2.devbox
192.168.3.99 website3.devbox

and edited my own resolv.conf file to include the devel box as a nameserver:

nameserver 192.168.3.99 

It's working fine, I can access the sites. The problem is that it doesn't scale well. I'd like all the domains ending with .devbox forwarded to the development box, and this is what I'm struggling with.

I have tried putting

192.168.3.99 devbox

into the hosts file, and editing the line in dnsmasq.conf:

# Add local-only domains here, queries in these domains are answered
# from /etc/hosts or DHCP only.
local=/devbox/

But I cannot get it working. If I try any URL that is not explicitly present in the development box's hosts file, the DNS lookup fails.

Is the local directive for something else? Am I looking at the wrong place?
