This blog post shows how to set up the Dynamic Update Client (DUC) for noip.com addresses. This allows access to (free) domains handled by noip.com, such as the one used by this website.<\/p>\n\n\n\n
This is useful if you don’t want to buy a domain name from a domain name registrar. Also, if you have several VMs setup on Oracle Free Tier, only one can have a fixed IP address, so this is useful for any that use a dynamic IP address.<\/p>\n\n\n\n
Note: noip.com used to allow 3 free hostnames per client, but I believe they have now dropped that down to 1 (for new clients). <\/em><\/p>\n\n\n\n Note: You need to sign up with noip.com before you can set up the Dynamic Update Client, as the set up procedure requires noip.com log in information.<\/em> See: https:\/\/www.noip.com\/remote-access<\/a><\/em><\/p>\n\n\n\n You need to have the standard Linux development tools installed in order to compile and install the Dynamic Update Client. Installing the development tools is covered in a separate blog post, see: Setting up development tools on Oracle Free Tier<\/a>.<\/p>\n\n\n\n Assuming you have the development tools installed, change to the root user with Check that the configuration file was created:<\/p>\n\n\n\n The Dynamic Update Client is now installed and configured.<\/p>\n\n\n\n Next, a systemd unit file needs to be created and installed, so that the Dynamic Update Client will automatically start when the system starts. <\/p>\n\n\n\n Change back to the folder that holds the no-ip archive that you downloaded, and create a file named noip2.service, and add the following contents:<\/p>\n\n\n\n Save the file, and then install it with:<\/p>\n\n\n\n Check that the service starts correctly:<\/p>\n\n\n\n There’s more information at: <\/p>\n\n\n\n <\/p>\n","protected":false},"excerpt":{"rendered":" This blog post shows how to set up the Dynamic Update Client (DUC) for noip.com addresses.
