As you probably already know, one of the main problems when you’re doing multiple projects is to organize them properly, first for fast local testing of changes, second for your own sake, to not get lost on your own computer. One more problem are the testing local domains. Well, the easiest way when you create a project is to create a new project folder, put a new domain (and every subdomain you’ll use) into your /etc/hosts file, create a new virtual host in the apache config, run a2ensite #### (or however you enable a new site on your distribution), restart the webserver… Which means, you need to do that everytime when you’re creating a new project. Not a very convenient way if you ask me, as you’re bloating your /etc/hosts file and your Apache2 virtualHost file(s).

I do a lot of work with subdomains, managing them locally on my development and test machines has always been a bit of a pain. Going way back, I can remember manually editing the hosts file in system32\drivers\etc\ on Windows! On the Unix we have /etc/hosts. Unfortunately /etc/hosts doesn’t allow wildcard definitions for subdomains, so you have to manually specify each one.

In a previous article, I talked about using subdomains in Rails 3. Since then, many people have elaborated on the topic. There's even been a great Railscast. I've found Tim Pope's post particularly useful. Basically, he has set up a domain name that resolves to locahost/127.0.0.1. This save you from having to specify subdomains in you /etc/hosts file - which is a hassle! I'd like to offer another alternative using Dnsmasq. With Dnsmasq, you can set up a simple DNS server locally, then you can use an apache virtual host to deal with wildcard domains.

Since 12.04 NetworkManager needs dnsmasq-base as a dependency, If dnsmasq is installed ie apt-get install dnsmasq it will try to bind to port 53 which is already in use because of NetworkManager. To resolve first comment the dnsmasq line from networkmanager.

Dnsmasq is a lightweight, easy to configure, DNS forwarder and DHCP server. It is designed to provide DNS and optionally, DHCP, to a small network. It can serve the names of local machines which are not in the global DNS. The DHCP server integrates with the DNS server and allows machines with DHCP-allocated addresses to appear in the DNS with names configured either in each host or in a central configuration file. Dnsmasq supports static and dynamic DHCP leases and BOOTP/TFTP for network booting of diskless machines.

Before you edit any files, you'll need to obtain some information. Log into the Linode Manager and click the "Remote Access" tab. You'll find your IP addresses (both public and private, if you have a private IP assigned), gateways, netmasks and DNS resolvers. Keep this information handy, because you'll need to refer to it as you configure your Linode's network settings. Since Linodes only have one virtual ethernet interface (eth0), you'll need to assign additional IPs to aliases on that interface. This means you'll append a colon and a number to the interface name. For these examples, the aliases are numbered in the order they were given, but most outbound connections will originate from the IP assigned to the eth0 interface. If you need server daemons to bind to a particular IP address, you'll need to specify the correct IP in their configuration files.

If the intricacies of bind are too much to navigate and all you really need is lightweight DNS services for your LAN, dnsmasq might fit the bill: Configure it with /etc/hosts, use it for easy DHCP services, and put the kibosh on the likes of Sitefinder's DNS-breaking marketing scheme. There you are on your small home LAN, or small business, feeling ignored by the Linux world. You want to take advantage of nice labor-saving tools like DHCP (dynamic host configuration protocol) and DNS (domain name system), but it feels like only uber-geeks need apply.
