In-Depth Information
This is where a free dynamic DNS service comes in handy. It allows you to associate
a domain name with your IP, which will be automatically updated every time your
IP changes. So wherever you may be in the world, all you need to remember is a
name like
gimmepi.mooo.com
and it will always point to your home network's
current external IP address.
Choosing your domain name
Start by signing up with a dynamic DNS service. There are quite a few to choose from
but we're going to look closer at
FreeDNS
. Follow these steps to get started with
FreeDNS:
the bottom of the page.
2. Fill out the form and keep an eye out for an e-mail from
dnsadmin@afraid.
org
.
3. Click on the account activation link in that e-mail to activate your
FreeDNS account.
4. Once you're logged in at FreeDNS, click on
Subdomains
in the menu to the
left, and then click on
Add a subdomain
to add a new subdomain.
5. Leave
Type
as
A
.
6. The
Subdomain
field is the part of the domain name where you get to put
whatever you want—preferably something short, unique, and easy for you
to remember.
7. From the
Domain
drop-down list you pick the second part that makes up
your domain name. The most popular ones are in this list, while another
thousand names or so can be picked from the
Registry
page in the menu to
the left.
8. Your current external IP goes into the
Destination
field. This is the field that
we'll be updating continuously as your IP changes.
9.
That's all there is to it. Click on
Save!
Verifying your domain name
To verify that your domain name has been added correctly and to find out what IP
address it's currently pointing to, we'll use the
nslookup
utility because it works
equally well on the Pi, on Windows, and on Mac OS X. The following are the steps to
verify the domain name:
1.
Install the
nslookup
utility on the Pi with the following command:
pi@raspberrypi ~ $ sudo apt-get install dnsutils
