Next we need to modify the permissions on the script so that it's executable and add the service: etc/rc.d/init.d/functions # uncomment/modify for your killproc As root, copy the following bash script and save it to /etc/init.d/noip2: Now we just need to create an init script that will automatically start the service when Debian boots. Most people can go ahead and say No here. The final question will ask you if you'd like to run a program upon completing a DNS update. 30 is a good default value, if you know that your IP changes more frequently then you may want to lower this value. This controls how often the service will check to see if your IP has changed. If you select No it will go through each host and allow you to pick which ones you'd like to update.Īfter you've made your selections it will ask for an interval (in minutes).
#DEBIAN DYN UPDATER UPDATE#
After you've entered your credentials the installer will tell you how many hosts (domains/subdomains) you have available and if you'd like to update them all. The first two will ask you for your No-IP username and password. Upon running the final command you should be presented with some configuration questions.
#DEBIAN DYN UPDATER INSTALL#
So we'll run a few commands to download the client, unpack it, build it, and install it: Note, if you have several machines all behind the same external IP then you really only need to install the No-IP client on one of your servers. The next step is downloading and installing the No-IP client that will update your DNS with your dynamic IP. By default No-IP will automatically default this value to whatever the external IP is of the system you're browsing the website with. You can do this by making sure that DNS Host(A) is selected and then typing your IP in. You should probably set the IP for the domain initially. The first thing you need to do is secure the domain either by means of creating a free account or purchasing a domain with No-IP.From the Hosts/Redirects tab, under Manage Hosts you'll want to click Add a host if you haven't already. I decided to use No-IP because they're one of the dynamic DNS providers that still offers a free account, this is useful if you're just learning and aren't quite ready to purchase a domain.
Using a dynamic DNS client, in this case with No-IP, we can setup Debian so that it will automatically update your DNS records when your IP changes. Usually your home router has one IP that usually changes from time to time. With all my other tutorials on setting up mail and web servers, I figured it only makes sense to write up a tutorial on setting up a Debian installation with a dynamic DNS client.
